Calculate the molar mass of the following compounds in g/mol.
CH3CO2H

Answers

Answer:

60g/mol

Explanation:

By using nucleon numbers given on the periodic table, the mass of 1 mole of each element is:

C= 12g

H= 1g

O= 16g

Since molar mass is the sum of the masses of each element present in the compound,

Molar Mass (Mr) = 12+3(1)+12+16(2)+1 = 60g/mol

Answers

Answer:

Explanation:

The temperature changes for the water and the metal is

ΔT (water) = 4.7°C

ΔT (metal) = - 72.9°C

Specific Heat

The quantity or amount of heat per unit mass required to raise the temperature of a body by one degree Celsius is known as specific heat. The unit of specific heat are joules or calories per gram per degree Celsius. Specific heat is an intensive property.

Calculate the temperature changes

Relationship between temperature and heat is expressed as:

Q = mcΔT

where,

Q is heat energy in Joules (J)

m is mass (in grams)

c is specific heat in J/g°C

ΔT is change in temperature

Now calculate the temperature changes for the water

ΔT (water) = T(final) - T(initial)

                 = 27.1 - 22.4

                 = 4.7°C

Now calculate the temperature changes for the metal

ΔT(metal) = T(final) - T(initial)

                = 27.1 - 100

                = -72.9°C

Thus, from the above calculation we can see that the temperature changes for the water and the metal is

ΔT (water) = 4.7°C

ΔT (metal) = - 72.9°C

How do the HOX genes in the paddlefish match the HOX genes in human

Answers

Answer:

Hox are transcription factors that are evolutionarily conserved across bilaterians and, therefore, they share sequence homology between paddlefish and humans .

Explanation:

The Hox genes represent a family of homeodomain transcription factors that play roles in the development of the axial and appendicular skeleton, being therefore critical during embryonic development. In this case, the human Hox genes are homologous to homeobox genes found in the paddlefish. These genes have a DNA-binding domain of 60 amino acids which is evolutionarily conserved in bilaterian species including paddlefish and human species.

A transformer has ten turns of wire on the input side and 50 turns of wire on the output side. If the input voltage is 120 V, what will the output voltage be?

Answers

Answer:

600 V

Explanation:

The transformer equation helps us to calculate the relationship between the ratio of the number of turns of coils in the input and output sources to their respective voltages.

It states that the ratio of the secondary to primary voltages in a transformer equals the ratio of the number of loops in their coils.

Number of input turns/Number of output turns = input voltage/output voltage

10/50 = 120V/output voltage

output voltage = 120 V/0.2

Output voltage = 600 V

6.87 x 107N
5.72 % 1014 N
1.03 * 1018 N​

Answers

Answer:

The gravitational  force between the satellites is [tex]3.81\times 10^{10}\ N[/tex].

Explanation:

Mass of satellite 1, [tex]m_1=5.3\times 10^{12}\ kg[/tex]

Mass of satellite 2, [tex]m_2=3.5\times 10^8\ kg[/tex]

Distance between masses is 1.8 m

It is required to find the gravitational  force between the satellites. The formula used to find the force between two masses is given by :

[tex]F=G\dfrac{m_1m_2}{r^2}\\\\F=6.67\times 10^{-11}\times \dfrac{5.3\times 10^{12}\times 3.5\times 10^8}{(1.8)^2}\\\\F=3.81\times 10^{10}\ N[/tex]

» POH = 3
pH =
» [OH ) = 1 x 10-2 M
pH =
» POH = 7
pH =

Answers

Answer:

The answer to your question is given below

Explanation:

1. Data obtained from the question include:

Hydrogen ion concentration, [H+] = 1x10^-9M

pH =..?

pH = - log [H+]

pH = - log 1x10^-9

pH = 9

2. Data obtained from the question include:

pOH = 3

pH =.?

Recall:

pH + pOH = 14

pH + 3 = 14

Collect like terms

pH = 14 - 3

pH = 11

3. Data obtained from the question include:

Hydroxide ion concentration, [OH-] = 1x10^-2M

pH =..?

First, we shall determine the pOH. This is illustrated below

pOH = - Log [OH-]

pOH = - Log 1x10^-2

pOH = 2

Finally, we can obtain the pH as follow:

pH + pOH = 14

pOH = 2

pH + 2 = 14

Collect like terms

pH = 14 - 2

pH = 12

4. Data obtained from the question include:

pOH = 7

pH =.?

Recall:

pH + pOH = 14

pH + 7 = 14

Collect like terms

pH = 14 - 7

pH = 7

They can warm up the water. Sugar dissolves much faster in warm/hot water.

A perfect example of this is when you put sugar in your hot coffee/tea -> it will dissolve almost immediately. If you put sugar in cold water, you will have to stir it for quite some time before it dissolves.

Answers

Answer:

Percent by mass of solute is (10/35) x 100 =  28.57%

Percent by mass of solvent is (25/35) x 100 = 71.43%

Explanation:

10.0 grams of solute

25.0 grams of solvent

Total Mass = 35 grams

percent by mass = (Mass A / Total Mass) x 100

Percent by mass of solute is (10/35) x 100 =  28.57%

Percent by mass of solvent is (25/35) x 100 = 71.43%

Ok so water is H2O and cabon dioxide in the air is CO2, so the water goes through the carbon dioxide and makes acid rain H2SO4.

Now we have our limestone which is CaCO3.

What happens is that the acid breaks apart our limestone into Ca2+ and CO3 2-. This then reforms into Calcium bicarbonate Ca(CO3)2.

Calcium bicarbonate is soluble in water and is hence washed away by the rain eroding the limestone.

Let's say you added too much magnesium in the amount of 0.1594 g. How much 8.00 M HCl (in mL) would be required to decompose the excess Mg present?
Mg(s) + 2 HCl(aq) --> MgCl2(aq) + H2(g)

Answers

Answer:

1.65×10^-3 L or 1.65 mL

Explanation:

Number of moles of magnesium in the excess reagent= mass of excess reagent/ molar mass of magnesium

Mass of excess magnesium= 0.1594 g

Molar mass of magnesium= 24 gmol-1

Number of moles of magnesium= 0.1594/24 = 6.6×10^-3 moles

From the reaction equation;

1 mole of magnesium reacted with 2 moles of HCl

6.6×10^-3 moles of magnesium will react with 6.6×10^-3 moles × 2= 13.2×10^-3 moles of HCl

But we know that;

Number of moles of HCl= concentration of HCl × volume of HCl

Volume of HCl= number of moles of HCl/ concentration of HCl

Since concentration of HCl= 8.00M

Volume of HCl= 13.2×10^-3/8.00= 1.65×10^-3 L or 1.65 mL
