Answer:
Natural Gas
Explanation:
It is when fossil fuels like coal and other <em>natural gasses</em> are burned that greenhouse gas is emitted. Nuclear power does hold some danger if left unchecked, but does not contribute to greenhouse gasses in a significant way. Hydroelectric energy does not produce any greenhouse gasses as well. Geothermal energy is also something that does not produce greenhouse gasses and is renewable. The main reason why natural gasses are still used although they produce large numbers of dangerous gasses is because they cost much less than the other energy sources on this list.

Explanation: don't have one :P
Answer:
i) Upwards delivery
ii) Downwards delivery
Explanation:
The methods used in the collection of gases are quite different depending on the state of the gas. The solubility and density of gases are the factors that determine the method of collection to be used.
Upwards delivery is used to collect gases that are soluble in water and lighter compared to air. Examples of these kind of gases include; Cl2 and SO2
Downwards delivery is used to collect gases that are soluble in water and denser than air. An example of this kind of gas is ammonia gas, NH4.
Molar mass FeTiO3 => 151.7102 g/mol
atomic mass Ti => 47.867 u
% ( atomic mass Ti / molar mass FeTiO3 ) x 100
= ( 47.867 / 151.7102) x 100
= 0.3155 x 100
= 31.55 % of Ti
hope this helps!
A) decomposers
Decomposers help break down organic matter and that produces things like minerals
