Answer:
D - chemical and physical
Explanation:
Only chemical and physical changes can reach the level of dynamic equilibrium. Nuclear reactions cannot reach dynamic equilibrium.
- A system is in dynamic equilibrium when the rate of forward reaction is the same as that of backward reaction in a reversible reaction.
- Nuclear reactions cannot be reversed.
- Dynamic equilibrium is prominent in chemical reactions. It is commonly found that as a reaction occurs, the backward and forward reactions can reach equilibrium levels.
- In physical changes, this can also occur when certain conditions of pressure and temperatures are satisfied.

Explanation:
A carbohydrate is formed from carbon, hydrogen and oxygen. These three elements are combined in every carbohydrate.
Even though carbohydrates are composed of only these three atoms, the number of atoms of these elements in each carbohydrate as well as the spatial arrangement of these atoms in each carbohydrate is not the same.
This means that different carbohydrates contain different number of carbon, oxygen and hydrogen atoms which are arranged in different ways in space. This gives room for the existence of many different types of carbohydrates all consisting of carbon, hydrogen and oxygen atoms.
The changes the masses of chalk on the scale because when it was dropped in Golden Hammer
(35 kg)*(1000 g / 1 kg)
(35 kg / 1 kg)*(1000 g)
kg units cancel, you're left with units of g
35/1*1000 = 35,000
ANSWER:
35,000 g
