M of CH2O= 12+2+16=30 g/mol
So 30g/mol = 3.5 mol
=> 16g/mol*3.5 divide by 30 = 1.86 mol
I think
The number of moles hydrogen produced when 6 moles of sodium are used is calculated as below
2Na + 2H2O = 2NaOH +H2
by use of mole ratio between Na to H2 which is 2:1 the moles of H2 is therefore
= 6 x1/2 = 3 moles of H2
Answer:
The relative number of products and reactants
Explanation:
- The numerical coefficients in chemical equations show the ratio of the molecules of each substance involved in a chemical reaction that is both reactants and products.
- The coefficients in a balanced chemical equation indicate the relative number of moles of reactants and products.
- Additionally, coefficients are important to prove the law of conservation of mass.
I don’t know if this is right but... would it be 9.81 m
