1 mole ------------- 6.02 x 10²³ atoms
0.70 moles -------- ( atoms zinc )
atoms platinum = 0.70 x ( 6.02 x 10²³ ) / 1
<span> = </span>4.2 x 10²³ atoms zinc
<span>hope this helps!</span>
Answer:
The entity that decreases is the Weight.
Explanation:
Every object on the surface of the earth is usually pulled downwards by the action of gravity. The force or weight is W = mg
Now, the farther one gets away from the surface of the earth by climbing a mountain, the further the person is from the Earth's centre of gravity.
We know that the formula for Force of gravity away from the Earth's surface is given by;
F_g = GM1M2/r²
So the greater the distance, the lesser the gravitational force.
Now, the gravitational force equals the weight of the individual.
Thus, the entity that decreases is the Weight of the individual.

Answer:
A. It is the ratio of the concentrations of products to the concentrations of reactants.
Explanation:
The equilibrium constant of a chemical reaction is the ratio of the concentration of products to the concentration of reactants.
This equilibrium constant can be expressed in many different formats.
- For any system, the molar concentration of all the species on the right side are related to the molar concentrations of those on the left side by the equilibrium constant.
- The equilibrium constant is a constant at a given temperature and it is temperature dependent.
- The derivation of the equilibrium constant is based on the law of mass action.
- It states that "the rate of a chemical reaction is proportional to the product of the concentration of the reacting substances. "
