TRUE
Explanation:
Covalent bonding occurs when pairs of electrons are shared by atoms. Atoms will covalently bond with other atoms in order to gain more stability. By sharing their outer most electrons, atoms can fill up their outer electron shell and gain stability. So, it is true.
Answer:
yes

The cell theory states that all biological organisms are composed of cells; cells are the unit of life and all life come from preexisting life. The cell theory is so established today that it forms one of the unifying principles of biology.
Make a ratio of the number of moles and do the calculations. Do you get it?
For the answer to the question above,
I am going to assume that MnO2 is a catalyst most likely breakdown of H2O2
H2O2----MnO2------> H2O + 1/2 O2
<span>in that case, B) is answered in the trump suit </span>
---
<span>edit: I need to have a plate account to see - which I don't </span>
is it something like
2H2O2 ---------------> 2H2O + O2
...............MnO2
<span>where MnO2 is underneath the arrow, in that case, it means it is a catalyst and production will DRASTICALLY decrease in production</span>
