Mark my answer as brainalist
The formula or chemical formula of a compound is same irrespective of source / mode of synthesis . Thus if a sample of compound has one carbon atom for every two atoms of oxygen (CO2), the formula will remains the same
So the answer is that for all other samples the compound X should hold this ration true.
Answer:
Potential Energy
Explanation:
Right now, the match is giving off no energy to it's environment.
<em>Light</em><em> </em><em>it</em><em>.</em>
Now it's giving off a few kinds:
- Thermal energy (heat)
- Light energy
The match has the potential to have energy, but it currently has none.
Answer:
The molarity of the solution remains unchanged.
Explanation:
Consider the formula for the molarity 
of a solution:
,
where
is the number of moles of solute in this solution, and
is the volume of the solution.
For this salt solution,
, and
.
Initial molarity:
.
Final molarity:
.
In other words, the molarity of the solution remains unchanged.
