b. False is the correct answer.

The standard unit for measuring mass is kilogram (kg), which is equal to 10^3 g. In chemistry, we use grams for measuring mass because we just usually use small amounts of stuff, so using grams is more sensible.

Hope this helps~

notka56 [123]

Well if we think about a food pyramid there are consumers that eat plants and if there are no plants to eat then those primary consumers die. Which means that the secondary consumers have no prey to eat and die as well, eventually leading to the top predators who have absolutely nothing to feed on.
They are the most affected because energy level decreases the higher up you go so the top predators need to eat more and if there is less and less to eat they die out quicker

Question 2 :

• While naming ionic compounds, follow the formula → "metal" + "non-metal ending with ide "

• i.e; Sodium Chloride:

Question 3 :

• The answer above that question is perfect.

Question 4 :

1 atom → Mono. But it is highly recommended to ignore it

2 atoms → DI

3 atoms → TRI

4 atoms → TETRA

5 atoms → PENTA ( such as pentaoxide )

7 atoms → HEPTA ( such as heptaoxide )

Question 5 and 6:

Are perfectly answered.
