Answer : The volume of water produced by this reaction would be, 4.75 liters.
Explanation : Given,
Volume of HCl gas = 9.5 L
The balanced chemical reaction will be:
As we know that at STP, 1 mole of gas occupy 22.4 L volume of gas.
By the stoichiometry we can say that:
As, 4 liter volume of HCl gas react to give 2 liter volume of water
So, 9.5 liter volume of HCl gas react to give 
volume of water
Therefore, the volume of water produced by this reaction would be, 4.75 liters.
The correct answer is option 4. In a double covalent bond, two pairs of electrons are bonded or there is a total of four electrons being shared in a bond. For example, we have oxygen. Two atoms of oxygen share two pairs of electrons to have a stable structure.
Answer:
Explanation:
We can use the Ideal Gas Law to calculate the density of the gas.
pV = nRT
n = m/M Substitute for n
pV = (m/M)RT Multiply both sides by M
pVM = mRT Divide both sides by V
pM = (m/V) RT
ρ = m/V Substitute for m/V
pM = ρRT Divide each side by RT
Data:
p = 1.00 bar
M = 49 g/mol
R = 0.083 14 bar·L·K⁻¹mol⁻¹
T = 0 °C = 273.15 K
Calculation:
ρ = (1.00 × 49)/(0.083 14 × 273.15) = 2.2 g/L
The density of the gas is .
Answer:
C
Explanation:
When fossil fuels are burned, they release large amounts of carbon dioxide, a greenhouse gas, into the air.
