What is the oxidation state of Hg in Hg2Cl₂?
O A. +1
OB. -1
O C. +2
OD. -2

Answers

Answer:

+1

Explanation:

The oxidation state of Hg in Hg2Cl2 is +1. It has +1 state. 0=2Hg +2 (-1) Hg=+1. Mercury chloride (HgCl2) is considered as the dominant form of mercury in coal combustion flue gas. The oxidation state of an atom is the charge of this atom after ionic approximation of its heteronuclear bonds. The oxidation number is synonymous with the oxidation state. Determining oxidation numbers from the Lewis structure (Figure 1a) is even easier than deducing it from the molecular formula (Figure 1b). The oxidation number of each atom can be calculated by subtracting the sum of lone pairs and electrons it gains from bonds from the number of valence electrons. Bonds between atoms of the same element (homonuclear bonds) are always divided equally. When dealing with organic compounds and formulas with multiple atoms of the same element, it's easier to work with molecular formulas and average oxidation numbers (Figure 1d). Organic compounds can be written in such a way that anything that doesn't change before the first C-C bond is replaced with the abbreviation R (Figure 1c). Unlike radicals in organic molecules, R cannot be hydrogen. Since the electrons between two carbon atoms are evenly spread, the R group does not change the oxidation number of the carbon atom it's attached to.

Calculate how many grams would be required to prepare 600. 0 ml of 0. 150 m of naf? molar mass of naf is 41. 9 g/mo

Answers

Considering the definition of molarity and molar mass, the mass of NaF required is 3.771 grams.

Definition of molarity

Molar concentration or molarity is a measure of the concentration of a solute in a solution and indicates the number of moles of solute that are dissolved in a given volume.

The molarity of a solution is calculated by dividing the moles of solute by the volume of the solution:

[tex]molarity=\frac{number of moles}{volume}[/tex]

Molarity is expressed in units [tex]\frac{moles}{liters}[/tex].

Definition of molar mass

The molar mass of substance is a property defined as its mass per unit quantity of substance, in other words, molar mass is the amount of mass that a substance contains in one mole.

Mass of NaF required

In this case, you know:

molarity= 0.15 M= 0.15 [tex]\frac{moles}{L}[/tex]number of moles= ?volume= 600 mL= 0.6 L

Replacing in the definition of molarity:

[tex]0.15\frac{moles}{L} =\frac{number of moles}{0.6 L}[/tex]

Solving:

0.15 [tex]\frac{moles}{L}[/tex] × 0.6 L= number of moles

0.09 moles= number of moles

The molar mass of NaF is 41. 9 g/mol. So, you can apply the following rule of three: If by definition of molar mass 1 mole of the compound contains 41.9 grams, 0.09 moles of the compound contains how much mass?

[tex]mass=\frac{0.09 molesx41.9 grams}{1 mole}[/tex]

mass= 3.771 grams

Finally, the mass of NaF required is 3.771 grams.

What is the volume in L of a 0.825 mole sample of Ar at 600 mm Hg and 300 K?

Answers

Answer:

V = 25.7 L

Explanation:

To find the volume of Argon (Ar), you need to use the Ideal Gas Law equation. This looks like:

PV = nRT

In this formula,

        > P = pressure (atm)

        > V = volume (L)

        > n = number of moles

        > R = constant (0.0821 L*atm/K*mol)

        > T = temperature (K)

While there is a different constant that can be used if you want to keep the pressure in mmHg, there is a more common constant used when the pressure is in atm. So, to find the volume, you need to (1) convert mmHg to atm (by dividing by 760) and then (2) calculate the volume (using Ideal Gas Law).

(Step 1)

600 mm Hg              1 atm
-------------------  x  ---------------------  =  0.789 atm
                              760 mm Hg

(Step 2)

PV = nRT

(0.789 atm) x V = (0.825 mole)(0.0821 L*atm/K*mol)(300 K)

(0.789 atm) x V = 20.32

V = 25.7 L

Taking into account the definition of density, the density of the glucose is 1.03 [tex]\frac{g}{mL}[/tex].

What is density

Density is defined as the property that matter, whether solid, liquid or gas, has to compress into a given space.

In other words, density is a quantity that allows us to measure the amount of mass in a certain volume of a substance. Then, the expression for the calculation of density is the quotient between the mass of a body and the volume it occupies:

[tex]density=\frac{mass}{volume}[/tex]

From this expression it can be deduced that density is inversely proportional to volume: the smaller the volume occupied by a given mass, the higher the density.

Density of the glucose

In this case, you know that:

Density= ?Mass= 20.6 gVolume= 20 mL

Replacing in the definition of density:

[tex]density=\frac{20.6 g}{20 mL}[/tex]

Solving:

density= 1.03 [tex]\frac{g}{mL}[/tex]

In summary, the density of the glucose is 1.03 [tex]\frac{g}{mL}[/tex].

This will cause the conversion because the molar mass exists as a ratio; technically, the ratio states that there are 101.96 grams per every 1 mole Al₂O₃. It is important to arrange the ratio in a way that allows for the cancellation of units. In this case, the desired unit (grams) should be in the numerator.

a. 1.38e4
b. 42.0
c. 93.8
d. 18.1

Answers

Answer:

a.  [tex]P_2=1.38*10^4[mmHg][/tex]

Explanation:

If the Temperature of a gas remains constant (and if the amount of gas molecules doesn't change), then compressing the gas from 12.11 L to 0.669L will increase its pressure through Boyle's Law:  [tex]P_1V_1=P_2V_2[/tex]

We'll also need to recall that atmospheric pressure with units of mmHg (since that is the unit requested in the answer) is 760 mmHg.

Letting the initial Pressure and Volume be the P1 and V1, and the final pressure be the P2 and V2, we can substitute and solve:

[tex]P_1V_1=P_2V_2[/tex]

[tex](760[mmHg])(12.11[L])=P_2(0.669[L])[/tex]

[tex]\dfrac{(760[mmHg])(12.11[L \!\!\!\!-])}{0.669[L \!\!\!\!-]}=\dfrac{P_2(0.669[L]\!\!\!\!\!\!\!\!\!\!\!\!\!\!\!\!\!\!\!\!\!\!{----})}{0.669[L]\!\!\!\!\!\!\!\!\!\!\!\!\!\!\!\!\!\!\!\!\!\!{----}}[/tex]

[tex]13757.2496[mmHg]=P_2[/tex]

Since the final pressure is only measured to 3 significant figures, we round the pressure accordingly

[tex]13800[mmHg]=P_2[/tex]
