A hypothetical gas that perfectly fits all the
assumptions of the kinetic- molecular theory is Ideal gas.
(they actually don't exist)
Honestly just look at the question deeper and find it inside the equation of the fraction
Answer: you have to be sure to cite evidence
Answer:
Rate of hydrogen formation is 0.05 mole per second
Explanation:
Firstly, we write the equation of reaction.
When alkali earth metals react with dilute mineral acid, the reaction is vigorous with the production or evolution of hydrogen gas as a result of the displacement of the hydrogen from the acid by the metal. This is one of the basic reactions of mineral acids
Ca + H2SO4 ——> CaSO4 + H2
Looking at the reaction, 1 mole of calcium gave 1 mole of the hydrogen gas
What we do now is to calculate the number of moles of calcium produced by 20g of Ca
Mathematically;
number of moles = mass/atomic mass
number of moles of calcium is thus
20/40 = 0.5 moles
Now, if 1 mole of calcium produced 1 mole of the gas
Definitely, 0.5 mole of calcium will produce 0.5 mole of the gas
So the rate of gas formation would be 0.5/10 = 0.05 mole/second
