The question is incomplete, here is the complete question:

Gaseous compound Q contains only xenon and oxygen. When a 0.100 g sample of Q is placed in a 50.0-mL steel vessel at 0°C, the pressure is 0.230 atm. What is the likely formula of the compound?

A. XeO

B. $XeO_4$

C. $Xe_2O_2$

D. $Xe_2O_3$

E. $Xe_3O_2$

<u>Answer:</u> The chemical formula of the compound is $XeO_4$

<u>Explanation:</u>

To calculate the molecular weight of the compound, we use the equation given by ideal gas equation:

PV = nRT

Or,

$PV=\frac{w}{M}RT$

where,

P = Pressure of the gas = 0.230 atm

V = Volume of the gas = 50.0 mL = 0.050 L (Conversion factor: 1 L = 1000 mL)

w = Weight of the gas = 0.100 g

M = Molar mass of gas = ?

R = Gas constant = $0.0821\text{ L atm }mol^{-1}K^{-1}$

T = Temperature of the gas = $0^oC=273K$

Putting value in above equation, we get:

$0.230\times 0.050=\frac{0.100}{M}\times 0.0821\times 273\\\\M=\frac{0.100\times 0.0821\times 273}{0.230\times 0.050}=194.9g/mol\approx 195g/mol$

The compound having mass as calculated is $XeO_4$

Hence, the chemical formula of the compound is $XeO_4$

How many moles of helium gas would it take to fill a balloon with a volume of 1000.0 cm 3when the temperature is 32 o C and the

vekshin1

The number of moles of the gas is 0.0396 moles.

<h3>What is the ideal gas equation?</h3>

The ideal gas equation is used to determine the relationship between the variables; temperature, pressure, volume and the number of moles of a gas. We know that the gas laws are used to understudy the parameters that has to do with gases.

Thus;

Volume = 1000.0 cm 3 or 1 L

Gas constant = 0.082 atmLK-1Mol-1

Temperature = 32 o C + 273 K = 305 K

Pressure = 752 mm Hg or 0.99 atm

Thus;

PV = nRT

n = PV/RT

n = 0.99 atm * 1 L/0.082 atmLK-1Mol-1 * 305 K

n = 0.0396 moles

The equation below shows the reaction of zinc with hydrochloric acid (HCl).

777dan777 [17]

Answer:

Explanation:

Zn + 2HCl ⇄ ZnCl₂ + H₂

A system in equilibrium will try to annul any stress placed on the system for it to maintain the equilibrium position.

For reactions in which concentration changes are effected, the equilibrium shifts to the right if the concentration of species on the reactant side is increased and vice versa.

In the reaction above, if the concentration of the HCl is decreased, the equilibrium will shift to the left in order to increase back the concentration of both the Zn and HCl. Therefore, the acid HCl will become more acidic.
