Given :
15 g of potassium react with water .
To Find :
How much potassium hydroxide and hydrogen gas will be produced by the chemical reaction .
Solution :
Balanced chemical equation is given by :
Number of moles of potassium are :
From the chemical equation we can see that 1 mole of potassium produce 2 moles of KOH and 1 mole .
So , 0.38 mole of potassium will produce :
Mass of KOH produced , .
Mass of produced , .
Therefore , mass of potassium hydroxide and hydrogen gas produced is 42.56 g and 0.76 g respectively .
Answer:
Nitrogen and Argon
Explanation:
These gases are part of a class of "noble" gases because they don't react with anything.
