The charge of a proton is +1, of an electron is -1, and of a neutron is 0.
12*(+1) +10*(-1) +14*0
= 12 -10
= +2
The correct answer is (2) +2.
Hope this would help~

Answer: homeostasis, the state of maintaining a stable internal environment despite changing external conditions.
Temperature, amount of sugar, and amount of water are some conditions that need to be right in the body for cells to work properly. When all the conditions are just right, the cells function properly.
The answer is b because as the air gets cooler and the moist in the air will drop as we call it dew
Answer:
For Mass N, Mass H, and Mass O, the mass is 28.0 g N, 4.0 g H, and 48.0 g respectively
Explanation:
The computation of the mass of each element is given below:
As we know that
A1 mole of ammonium nitrate i.e. 2 mol N, 4 mol H, 3 mol
Now we multiply each of above by the molar masses
For N
= 14.0 g/mol × 2
= 28.0 gN
For H
= 1.0 g/mol × 4
= 4.0 gN
ANd, for O
= 16.0 g/mol × 3
= 48.0 gN
Hence, For Mass N, Mass H, and Mass O, the mass is 28.0 g N, 4.0 g H, and 48.0 g respectively
