Answer:
The statement H is the correct one: The number of atoms on the reactant side equals the number of atoms on the product side.
Explanation:
The law of conservation of mass states that mass can not be created or destroyed, just can be transformed. The mass of a system can not be added or removed, thereby the transfer of mass in a reaction must remain constant.
This implies that the mass of the molecules on the side of the reactants before the reaction must be equal to the mass of the atoms on the side of the products after the reaction.
Therefore, the statement H is the correct one: The number of atoms on the reactant side equals the number of atoms on the product side.

The suns powerful UV rays hit her skin without any protection (sunscreen)
The solution for this problem is:
If they feel 50% of their weight that means that the
centripetal force is also 50% of their weight 1g - 0.5g = 0.5g
Then 0.5* 9.8m/s² * 18m = 88.2 would be v²
Then get the square root, the answer would be:
and v = 9.391 m/s is the answer.
Answer:
