Because it has more protons than electrons. Protons are positive so if there is more of them than electrons, the ion will have a positive charge.
Answer : The number of grams of calcium perchlorate is, 0.00253 grams.
Explanation :
Molar mass of calcium perchlorate = 238.9 g/mol
As,
formula units present in 238.9 g of calcium perchlorate
So,
formula units present in
of calcium perchlorate
Therefore, the number of grams of calcium perchlorate is, 0.00253 grams.
Answer:
B! SPIRAL CAUSE ITS SPINNY AND PRETTY UWUUUUUU hehe :3
I hope my photo helps. since oxygen goes from a charge of 0 to -2, it gains electrons because electrons have a negative charge. nitrogen goes from 0 to +2 meaning that it is losing electrons to make it a positive charge.
