Answer:
Explanation:
Equation of reaction:
2HCl → H₂ + Cl₂
From the equation of reaction,
From ideal gas equation,
PV = nRT
P = pressure of the ideal gas
V = volume of the gas
n = number of moles
R = ideal gas constant
T = temperature of the gas
At STP,
P = 1.0atm
T = 273.15K
R = 0.082J/mol.K
PV = nRT
1 .0 × 11.2 = n × 0.082 × 273.15
11.2 = 22.398n
n = 11.2 / 22.398
n = 0.50mole
From the equation of reaction,
2 moles of HCl = 1 mole of Cl₂
X moles HCl = 0.5mole
X = (2 × 0.5) / 1
X = 1 mole of HCL
Number of mole = mass / molar mass
Molar mass of HCl = 1 + 35.5 = 36.5g/mol
Mass = number of mole × molar mass
Mass = 1 × 36.5
Mass = 36.5g
36.5g of HCl is required to to produce 11.2L of Cl₂
<span>Which of the following gases would be most likely to experience ideal behavior at high pressures?
a. F2
b. Ne
c. C2H6
Yes. The answer is (b) Ne (Neon). This is because monoatomic gases such as neon do not experience </span><span>intermolecular attractions and thus most likely to be close to ideal gases behavior. Not only that, Neon is a noble gas and is unreactive. </span>
Answer:
<h3>The answer is 8.89 g/cm³</h3>
Explanation:
The density of a substance can be found by using the formula
From the question
mass = 75.6 g
volume of copper = 8.5 cm³
We have
We have the final answer as
<h3>8.89 g/cm³</h3>
Hope this helps you
