Answer:
2AlPO4(aq) + 3Mg(s) -------> Mg3(PO4)2(aq) + 2Al(s)
Explanation:
The principle of writing balanced chemical reaction equations states that; the number of atoms of each element on the right hand side of the reaction equation must be equal to the number of atoms of the same element on the left hand side of the reaction equation.
The reaction is between aqueous aluminum phosphate reacts and solid magnesium to produce solid aluminum and aqueous magnesium phosphate. The equation is represented as follows;
2AlPO4(aq) + 3Mg(s) -------> Mg3(PO4)2(aq) + 2Al(s)
Coal can replace petroleum base fuel when you are just heating something that dont need big amount of heat. examples of it is when producing steam, coal is just used to heat water and produce steam because coal is much cheaper and the coal can already do the job in heating the water
Answer:
Explanation:
The equation tells you that for every mol of H2 you need 2 mols of Na to get it.
1 H2 / 4 mols H2 = 2 mols Na / x Cross multiply
1*x = 4 * 2
x = 8 mol Na
Answer: C... Because Zinc is made of only one type of atoms.
Explanation: All elements are made of one type of atom. Pure gold is made out of only gold atoms, silver out of only silver atoms, etc.
