The volume : V₁ = 1.29 ml
<h3>Further explanation</h3>
Given
V₂=450 ml
M₂=0.02
M₁=7.0
Required
V₂
Solution
Dilution is the process of adding solvent to get a more dilute solution.
The moles(n) before and after dilution are the same.
n₁=n₂
Dilution formula :
M₁V₁=M₂V₂
Input the value
V₁= (M₂V₂)/M₁
V₁ = (0.02 x 450)/7
V₁ = 1.29 ml
Answer:
The definition of conceptual is something having to do with the mind, or with mental concepts or philosophical or imaginary ideas. An example of conceptual is when you formulate an abstract philosophy to explain the world which cannot be proven or seen. "Conceptual."

Explanation:
The <u>First Law of Thermodynamics</u> states that energy cannot be created or destroyed in an isolated system. In other words, energy can be converted from one form into another, but it cannot be created nor destroyed.
<u>Conduction</u> is the transfer of energy from one molecule to another by direct contact. This transfer occurs when molecules hit against each other, which can take place in solids, liquids, and gases.
When you put your cold hands under your legs to warm your hands up, the heat energy from your legs is being transferred to your hands through conduction. However, since energy cannot be created, there is no extra heat energy that can instantaneously replace the heat created by your legs.
Explanation:
In any chemical change, one or more initial substances change into a different substance or substances. ... According to the law of conservation of matter, matter is neither created nor destroyed, so we must have the same number and kind of atoms after the chemical change as were present before the chemical change
Example:
The carbon atom in coal becomes carbon dioxide when it is burned. The carbon atom changes from a solid structure to a gas but its mass does not change.
