Answer:
B6Br4
Explanation:
Chemical formula gives a representation of the number of atoms that each element in a compound or molecule. In this question which is asking to give the formula of hexaboron tetrabromide, the hexa means 6 while the tetra means four.
Since the number of atoms of each element is written as a prefix before the main element, this means that the chemical formula of hexaboron tetrabromide will be B6Br4.
Answer:
a) Sm
Explanation:
Hello,
This substantiation could be done by knowing how to compute the released energy for 1 mol the oxide. Thus, for Sm, the computation turns out into:
The sign just indicates that the heat is released due to the chemical reaction and it matches with the indicated heat in the statement.
Best regards.
Answer:
when they have eight valence electrons.
Explanation:
When atoms do not have a full valence shell, the atoms are more likely to react with other and vice versa.
