Answer:
the answer is 10
Explanation:
Al2 is 2 atoms by itself
(SiO3)2 is 8 because Si is a single atom and O3 is 3 oxygen atoms but because of the subscript outside of the parentheses it doubles and becomes 2 and 6 respectively
Answer: Theoretical yield is calculated based on the stoichiometry of the chemical equation. The actual yield is experimentally determined. The percent yield is determined by calculating the ratio of actual yield/theoretical yield.
Explanation:
Answer:
mass of CH4 = 14
Molecular mass of CH4 16.04gmol
No of mole of CH4 = 14/16.04
No of mole of CH4 = 0.8728mol
Stoichiometrically, from the above
2 Molecules of Hydrogen will produce 1molecule of methane
Therefore, 2*0.8728 mole of Hydrogen will produce 0.8728mol of Methane.
The no of molecule of hydrogen is 1.7456
Atomic number The atomic number of each element is different than other Elements.
