Answer:
Higher levels of organization are built from lower levels. Therefore, molecules combine to form cells, cells combine to form tissues, tissues combine to form organs, organs combine to form organ systems, and organ systems combine to form organisms.
KOH + H2SO4 —> K(+) + HSO4(-) + H2O
Or a total reaction
2 KOH + H2SO4 —> 2 K(+) + SO4(2-) + 2 H2O
Which is the correct order of ease of carbon dioxide production by heating the group II metal carbonates?
A) 
B) 
C) 
D) 
Answer:
Explanation:
The correct option is A:
<h2>
</h2>

On the periodic table, carbonates required stronger heating as one does down the groupings in order for them to decompose. The implication is that the stability of compounds will increase from
to
.
So the carbonates will be stable according to the following order:
, thus making B the correct answer.
