Answer:
m O2 = 116,16 g
Explanation:
Ca(ClO3)2 ------------> CaCl2 + 3O2
n Ca(ClO3)2 = 250/207 = 1,21 mol
n O2 = 3n Ca(ClO3)2 = 1,21 * 3 = 3,63 mol
m O2 = 3,63 * 32 = 116,16 g
Answer:
2 Moles
Explanation:
12 grams of carbon contains 1 mole
1 gram contains [1 mole/ 12 grams ] x 1 gram
24 grams contains [1 mole/ 12 grams ]* 24 gram = 2 moles.
Answer: This means that the answer can be proven wrong.
Explanation:
Hope this helps!!
Answer:
Because Rutherford's model was weak on the position of the electrons, Bohr focused on them. He hypothesized that electrons can move around the nucleus only at fixed distances from the nucleus based on the amount of energy they have. ... However, an electron could never exist in between two energy levels
