Explanation:
Element is a pure substance which is composed of atoms of similar elements.It can not be decomposed into simpler constituents using chemical reactions.Example: Copper
Compound is a pure substance which is made from atoms of different elements combined together in a fixed ratio by mass.It can be decomposed into simpler constituents using chemical reactions. Example: water
Mixture is a substance which has two or more components which do not combine chemically and do not have any fixed ratio in which they are present. Example: Air
Here’s the math for your answer, which is 3.3 L HCl
Answer: A balanced equation for the given reaction is .
Explanation:
The reaction equation will be as follows.
Number of atoms on the reactant side is as follows.
- O = 2
- C = 1
Number of atoms on the product side is as follows.
- Ni = 1
- O = 2
- C = 1
Since number of atoms on both the reactant and product sides are equal. Hence, the reaction equation is balanced.
Thus, we can conclude that a balanced equation for the given reaction is .
