Adaptation actually and also following control measures on how to avoid it from happening
The first one is D, the second one is A and the last is C and D
Answer:
- 53 protons
- 131g
- Iodine
- Halogens
Explanation:
atomic no. = no. of protons
= 53 proton
mass = no. of protons + no. of
neutrons
= 53 + 78
= 131
Convection currents are caused by the movement of the magma in the mantle.
Hope This Helps You!
Good Luck Studying :)
No atoms are lost or made during the chemical reaction so the total mass of the products is equal to the total mass of the reactants. In an atom, protons and neutrons contribute to the mass and since the number of them doesn’t change, the mass doesn’t either.
