Answer: Option (b) is the correct answer.
Explanation:
According to ideal gas law, the product of pressure and volume is equal to the product of number of moles, gas constant and temperature.
Mathematically, PV = nRT
So, when there are two gases with equal number of moles behaving ideally then the ideal gas equation will be as follows.
=
and =
Hence, when temperature and pressure of both the gases will be constant then = 1.
Thus, we can conclude that constant temperature and pressure is the conditions that must be met for a volume ratio to be created from a balanced chemical equation.
Answer:
B.) 2x
Explanation:
Hello,
In this case, we can apply the following rule of three, knowing that 0.1 dm³ equals x and 0.2 dm³ is the unknown:
Thus, solving for the unknown we find:
Therefore, the answer is B.) 2x.
Best regards.
