Christians call Jesus "the Christ” because of the meaning behind the word. The term “Christ” comes from the Greek word “Christos” which means “the anointed one” or “the messiah”.

This title was given to Jesus because of the many prophecies in the Old Testament that foretold of a coming messiah who would save the people of Israel from their enemies and bring peace and justice to the world.

The term “Christ” is also associated with the Latin word “Nazareth”, which is the town where Jesus was born. This further reinforces the idea of Jesus as the messiah, as it was prophesied that the messiah would be born in Bethlehem, which is a town near Nazareth.

Finally, the term “Christ” is also associated with the Latin word “resurrection”. This is because Jesus was believed to have been resurrected from the dead, which was seen as proof of his divine power and the fulfillment of the prophecies about the messiah. This further emphasizes the idea of Jesus as the messiah and savior of the world.

In conclusion, Christians call Jesus “the Christ” because of the meaning behind the word and because of the many prophecies in the Old Testament that foretold of a coming messiah who would save the people of Israel from their enemies and bring peace and justice to the world. The term is also associated with the Latin words “Nazareth” and “resurrection”, which further emphasize the idea of Jesus as the messiah and savior of the world.

Explanation:

Hydrogen bond is an intermolecular interaction/bonding that are formed between an electronegative atom (such as nitrogen, oxygen and fluorine) and a hydrogen atom. They are weak intermolecular bonds compared to covalent bonds but account for the high boiling point of water because of the strong hydrogen bond presence between the water molecules. Water molecules form hydrogen bonds between each other; since an oxygen atom (in a water molecule) has two lone pairs on it's outermost shell, it forms an hydrogen bond with two hydrogen atoms of other water molecule. Due to the fluidity of liquid water molecules, hydrogen bonds keep getting broken (although recreated/formed almost immediately), hence, individual hydrogen bonds in liquid water does not exist for long.

In the explanation above, it was stated that the strength of the hydrogen bond in water is the reason for it's high boiling point. The atoms in a water molecule are bent NOT linear hence the strength of hydrogen bond does not depend on the linearity of the atoms involved in the bond.

Answer:

2.8 atm.

Explanation:

From the question given above, we obtained the following data:

Initial volume (V1) = 6.2 mL

Initial pressure (P1) = 1.4 atm

Final volume (V2) = 3.1 mL

Final pressure (P2) =?

The final pressure of the gas cylinder can be obtained by using the Boyle's law equation as shown below:

P1V1 = P2V2

1.4 × 6.2 = P2 × 3.1

8.68 = P2 × 3.1

Divide both side by 3.1

P2 = 8.68/3.1

P2 = 2.8 atm

Therefore, the final pressure of the gas cylinder is 2.8 atm

Answer:

c. 100:1.

Explanation:

Hello,

In this case, considering the Henderson-Hasselbach equation:

[tex]pH=pKa+log(\frac{[A^-]}{[HA]} )[/tex]

And the pH two units above the pKa:

[tex]pH=pKa+2[/tex]

We obtain the required ratio as follows:

[tex]pKa+2-pKa=log(\frac{[A^-]}{[HA]} )\\\\\frac{[A^-]}{[HA]} =10^2=100[/tex]

Which is also a c. 100:1 ratio containing 100 parts of base per 1 part of acid.

Regards.

According to Henderson - Hawelbach equation:

[tex]\to pH = pka + \log (\frac{A^{-}}{HA})...........(a)[/tex]

According to question pH two unit above pka:

[tex]\to pH = pka + 2[/tex]

Put value of PH is equation (a)

[tex]\to pKa+2=pKa+ \log (\frac{A^{-}}{HA})\\\\\to 2= \log (\frac{A^{-}}{HA})\\\\\to (\frac{A^{-}}{HA})= 10^2\\\\\to (\frac{A^{-}}{HA})= 100\\\\[/tex]

So, the ratio is [tex][100 : 1][/tex]

Therefore, 100: 1 Ratio containing 100 part of base per 1 part of acid.

Answer:

The correct answer is 0.50 mol (NH₄)₃PO₄

Explanation:

The balanced chemical equation between liquid ammonia (NH₃) and H₃PO₄ is the following:

3 NH₃ + H₃PO₄ → (NH₄)₃PO₄

According to the equation, 3 mol of ammonia produce 1 mol of ammonium phosphate. Thus, the stoichiometric ratio is 1 mol (NH₄)₃PO₄/3 NH₃. To calculate the moles of (NH₄)₃PO₄, we multiply the ratio by 1.50 mol NH₃:

1.50 mol NH₃ x 1 mol (NH₄)₃PO₄/3 NH₃ = 0.50 mol (NH₄)₃PO₄

Answer:

Option A. 0.330 atm.

Explanation:

To know the correct answer, we simply do the following:

1. Conversion of 251 torr to atm

760 torr = 1 atm

Therefore,

251 torr = 251 torr / 760 torr × 1 atm

251 torr = 0.330 atm

2. Conversion of 251 torr to psi

1 torr = 0.0193 psi

Therefore,

250 torr = 250 torr / 1 torr × 0.0193 psi

250 torr = 4.825 psi

From the above illustrations, 251 torr is equivalent to both 0.330 atm and 4.825 psi. Therefore, only option A is correct.

C) 107 g

Explanation:

Step 1: Calculate the molar mass of Ca(NO₃)₂

We can calculate the molar mass of Ca(NO₃)₂ by adding the masses of its elements.

M = 1 × Ca + 2 × N + 2 × 3 × O

M = 1 × 40.08 g/mol + 2 × 14.01 g/mol + 6 × 16.00 g/mol

M = 164.10 g/mol

Step 2: Calculate the mass corresponding to 0.650 moles of Ca(NO₃)₂

We multiply the number of moles by the molar mass.

0.650 mol × 164.10 g/mol = 107 g

Explanation:

The following data were obtained from the question:

Mass of SF6 = 45.0 g

Number of mole of SF6 =..?

Next, we shall determine the molar mass of SF6.

This can be obtained as follow:

Molar mass of SF6 = 32 + (19×6)

Molar mass of SF6 = 32 + 114

Molar mass of SF6 = 146 g/mol

Finally, we shall determine the number of mole in 45 g of SF6 as follow:

Molar mass of SF6 = 146 g/mol

Mass of SF6 = 45.0 g

Number of mole of SF6 =..?

Number of mole = mass /Molar mass

Number of mole of SF6 = 45 /146

Number of mole of SF6 = 0.31 mol

Therefore, 0.31 mol is present in 45 g of SF6.

Answer:

Reaction: [tex]\rm HF + H_2O \rightleftharpoons F^{-} + H_3O^{+}[/tex].

Explanation:

In the Bronsted-Lowry acid-base theory, the acid in a reaction is the species that loses a proton, [tex]\rm H^{+}[/tex]. The resultant species would be the conjugate base of that acid.

On the other hand, the Bronsted-Lowry base in a reaction is the species that accepts a proton [tex]\rm H^{+}[/tex]. The resultant species would be the conjugate acid of that base.

Identify the conjugate acid-base pairs in this reaction. Note that the two species in each pair are related by the gain or loss of a single proton. Therefore, their formula should look similar to each other.

For this reaction, [tex]\rm HF[/tex] and [tex]\rm F^{-}[/tex], as well as [tex]\rm H_2O[/tex] and [tex]\rm H_3O^{+}[/tex] form two similar-looking reactant-product pairs:

Answer:

The limiting reactant is CH₄

26.0g of CH₂Cl₂ is the maximum amount that can be formed

4.15g CCl₄ will remain

Explanation:

The reaction of methane, CH₄, with carbon tetrachloride, CCl₄ is:

CH₄ + CCl₄ → 2CH₂Cl₂

To find the maximum mass of dichloromethane that can be determined we need to find moles of methane and carbon tetrachloride:

Moles CH₄:

2.45g * (1mol / 16.04g) = 0.153 moles

Moles CCl₄:

27.7g * (1mol / 153.82g) = 0.180 moles

That means just 0.153 moles of CCl₄ will react until CH₄ is over.

The limiting reactant is CH₄

Assuming the whole 0.153 moles will react, the moles of CH₂Cl₂ will be:

0.153 moles CH₄ * (2 moles CH₂Cl₂ / 1 mole CH₄) = 0.306 moles of CH₂Cl₂

The mass is (Molar mass dichloromethane: 84.93g/mol):

0.306 moles of CH₂Cl₂  * (84.93g / mol) = 26.0g of CH₂Cl₂

The moles of CCl₄ that remain are:

0.180 moles - 0.153 moles = 0.027 moles

In grams:

0.027 moles * (153.82g / mol) = 4.15g CCl₄

Answer:

A. 3.7 x 10⁻³

Explanation:

In the beginning of the reaction there are 0.200 moles of reactant. After 25 minutes, remain 0.108 moles. That means the moles that wer descomposed are:

0.200 moles - 0.108 moles = 0.092 moles of reactant were descomposed.

That descomposition occurs in 25 minutes. The average rate of descomposition in moles / minute are:

0.092 moles Methyl isonitrile / 25 minutes = 3.7x10⁻³ mol/min.

Right option is:

Answer:

C. NaOH(s) + HCl(aaq) rightarrow NaCl(s) + H2O(aq)

Explanation:

A neutralization reaction may be defined as the reaction where an acid when it reacts with some base, the products formed are a salt and water.

Simply, we can write,

acid + base --->  salt + water

Here in option (C),

NaOH is sodium hydroxide is an base

HCl is hydrochloric acid

NaCl is sodium chloride and is the common salt

H20 is water

So, option C).  NaOH(s) + HCl(aaq) -----> NaCl(s) + H2O(aq)   is a neutralization reaction.

an experiment should be replicated for one: it my give more reason to people who did not do it them selves two: during the experiment one variable could have been wrong like a gust of wind or a draft that's why you should conduct the experiment 3 to 4 times then get the medium or the average of your results giving you a more accurate answer.

Answer:

A. When a liquid is first placed in a closed container, the evaporation rate is higher than it is in an open container under the same conditions.

Explanation:

Evaporation refers to the process by which a liquid changes to gas or vapor. It usually occurs at the surface of a liquid.

Factors that affects evaporation include; nature of the liquid, surface area of liquid exposed, temperature and wind.

Considering the options given:

A. When a liquid is first placed in a closed container, the evaporation rate is higher than it is in an open container under the same conditions. = False

This is false because, the more the surface of the liquid exposed, the higher the rate of evaporation.

B. When a liquid is first placed in a closed container, the evaporation rate is higher than the condensation rate. = True

This is true because when a liquid is first placed in a container, the equilibrium position favors evaporation initially than condensation as saturation of the space above the liquid with vapor has not been achieved.

C. When the rates of evaporation and condensation are equal, the system has reached dynamic equilibrium.= True

Dynamic equilibrium is achieved when the rate of forward and backward reaction, in this case, evaporation and condensation are equal.

D. Vapor pressure refers to the pressure of a gas at a given temperature in equilibrium with its liquid phase. = True

E. Stronger intermolecular forces within the liquid typically result in a lower vapor pressure under a given set of conditions.  = True

Strong intermolecular forces between the molecules of the liquid causes the liquid to remain in the liquid state rather than turning to vapor, thereby lowering vapor pressure

Answer: d. The temperature of the liquid is 60°C.

Explanation:

A quantitative observation is an observation of measure of variables sing in the study or experiment . Variables can be length, weight, temperature , volume etc which can be measured.

From all the given options only option d. is describing a measure ( 60°C).

Hence, an example of a quantitative observation: "The temperature of the liquid is 60°C."

So correct option is d.

Answer:

A good experimental design should always: include more than one independent variable. have predictable outcomes. be repeatable.
