It could both the 2nd and the 3rd,
because if you add the exponents (2 + 1 + 6 = 9) you don't get 10.
and also each orbital level can and has to carry 2 electrons, and the 2s only has 1 there.
Answer:
true
Explanation:
heat will destroy the salt components quicker
Answer:
4 Sb (+3) + 2 Br (2) O (3) ----> 4 SbBr + 3 O(-2)
In the equation, place the valences in parentheses and the stoichiometric balance numbers so that the reaction is balanced, place them in bold.
Explanation:
In this chemical equation it seems to me that the valences of BrO are wrong.
That is why I will complete the equation, demonstrating the chemical reaction, and also use the appropriate valences.
Assuming that Sb has a valence of +3 and that the Br that appears in the form of oxide with oxygen (valence -2) has a valence of +3 (because -3 does not exist as valence or oxidation state of bromine).
Answer:
pretty sure it's D but I'm not exactly sure
