Calcium’s atomic number is 20. it forms ions with 18 electrons. what is the electrical charge of a calcium ion?
Gnom [1K]
It would be a positive charge because it lost two electrons, if the charge was neutral it would be the same amount of protons and electrons, if the charge was negative the electrons would be 20 instead of 18. So in this case it is positive.

Ammonium perchlorate NH4ClO4 is a powerful solid rocket fuel, used in the Space Shuttle boosters. It decomposes into nitrogen N2
patriot [66]

Answer: 0.055 moles of O_2 are produced by the reaction of 0.055 mol of ammonium perchlorate.

Explanation:

The balanced chemical reaction for decomposition of ammonium perchlorate is:

2NH_4ClO_4\rightarrow N_2+Cl_2+2O_2+4H_2O  

According to stoichiometry :

2 moles of NH_4ClO_4 produce = 2 moles of O_2

Thus 0.055 moles of NH_4ClO_4 will produce =\frac{2}{2}\times 0.055=0.055moles of O_2

Thus 0.055 moles of O_2 are produced by the reaction of 0.055mol of ammonium perchlorate.
