The equation for the reaction between hydrogen gas and oxygen gas is: 2H2(g) + O2(g) ---> 2H2O(l) i) How much hydrogen will react with 8g of oxygen? ii) how much water will be formed when 6g of hydrogen react? i would appreciate your help.

My question is very simple Why do metals when react with oxygen are called oxides like " magnesium oxide" whereas non metals reacting with oxygen become dioxides like "carbon dioxides" , note that the two react with oxygen which has 2 molecules

Chemicals don't react in grams. They react in moles. For example, the equation 2NaOH + H2SO4 ==> Na2SO4 + 2H2O tells you that 2 moles NaOH react with 1 mole H2SO4 to produce 1 mole Na2SO4 and 2 moles H2O. If we start with grams NaOH and want to know how many grams H2SO4 ...
