Petroleum is used as a fuel to power vehicles and machines.
Petroleum products include fuel oils for heating and electricity generation.
It is a feedstocks for making the chemicals and plastics.
We use petroleum to produce electricity.
Answer:
0.57 water
Explanation:
To solve this problem, we need to write the reaction expression first.
The reactants are oxygen gas and hydrogen gas.
They react to give a product of water
2H₂ + O₂ → 2 H₂O
Given that;
Number of moles of hydrogen gas = 0.57moles
From the balanced reaction expression;
2 moles of hydrogen gas produces 2 moles of water
So;
0.57mole of hydrogen gas will also produce 0.57 water
I’m pretty sure the answer is A.
In a nucleotide, we find CARBOHYDRATE making up a piece of the nucleotide itself. An example of the type of carbohydrate found in nucloetides is de-oxy ribose. Deoxyribose is a five carbon sugar {pentose} which is part of the building blocks of nucleotide.<span />
Answer:
(4)KBr(aq)
Explanation:
A mixture is an impure substance made up of two or more substances that are joined together. Their composition is indefinite and not easily represented by a simple chemical formula.
KBr
is a mixture because it made up of an aqueous solution of KBr. This suggests that the substance KBr is placed inside water.
Here, we have two states of matter which is the solid and the liquid coming together.
As with both mixtures, they can be separated by physical means, KBr aqueous solution can also be done this way.
