A is a model of a decomposition reaction
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.

The answer would be A: its container.
Gas will expand to fill whatever container it is put in.
Answer: The correct statements are ; A and B.
Explanation:
The strength of the magnetic field(B) in an electromagnet can be calculated using formula:
= Relative permeability
N = number of turns
I = Current in the wire of the solenoid
L = length of the solenoid or electromagnetic
As we can see from the formula:
So, by increasing the turns and increasing current flowing through wire one can increase the strength of an electromagnet.
Hence, the correct statements are ; A and B.
Answer:
a. 0.5 mol
b. 1.5 mol
c. 0.67
Explanation:
Fe3+ + SCN- -----> [FeSCN]2+
a. The ratio of the product to Fe3+ is 1:1. Meaning that if 0.5 mol of product was produced up then 0.5 mol of Fe3+ was used. Leaving 0.5 mol remaining at equilibrium
b. The ratio of the product to SCN= is 1:1. Meaning that if 0.5 mol of product was produced up then 0.5 mol of SCN- was used. Leaving 1.5 mol remaining at equilibrium
c. KC = 0.5/(0.5*1.5) = 0.67
