Answer:
Explanation:
The limiting reactant (or limiting reagent) is the reactant that gets consumed first in a chemical reaction and therefore limits how much product can be formed.
GPE is the gravitational Potential Energy which is given by mgh.
mg is the gravitational force(a force) and h is the height of the object(or distance of the object from earth's surface)
SO GPE = mg (force) x h (distance)
B. Regulating Services
Explanation:
Pollination is an example of regulating ecosystem service.
- Ecosystem services are the direct and indirect contribution to human life.
- Humans relies on the ecosystem for a wide range of provisions.
- These services are categorized into different forms.
- Regulating services are the values derived from controlling the ecosystem.
- Pollination is one of such things.
- Plants are pollinated by insects. This helps to continue and sustain life.
- Pollination helps to fertilize plants and ensures reproduction.

Answer:
pH = 3.65
Explanation:
given data
pKa of HNO2 = 3.40
nitrous acid (HNO2) = 0.110 M
NaNO2 = 0.200 M
to find out
What is the pH
solution
we get here ph for acidic buffer that is express as
pH = pKa + log(salt÷acid) ........................1
put here value and we get
pH = 3.40 + log(0.200÷0.110)
pH = 3.65
