Answer:
2 CH2 + 3 O2 = 2 CO2 + 2 H2O
Explanation:
This is what I think that you meant by the question listed. When balancing a chemical equation, you want to make sure that there are equal amounts of each element on each side.
Originally, the equation's elements looked like this: 1 C on left & 1 C on right; 2 H on left & 2 H on right; 2 O on left and 3 O on right. Because these are not balanced, you need to add coefficients.
When adding coefficients, you need to make sure that all of the elements stay balanced, not just one that you are trying to fix. I know that some equations are really difficult to balance, and when that is the case, there are equation balancing websites that can help out.
However, what always helps me is making a chart and continuing to keep up with the changes I am making. It is a trial and error process.
Answer:
No more than 0.1 mL of hydrochloricton acid
Answer:
The molarity of the solution is 0.29
Explanation:
Molarity, or molar concentration, is a measure of the concentration of a solute in a solution, be it some molecular, ionic or atomic species. It is defined as the number of moles of solute that are dissolved in a given volume.
Molarity is calculated as the quotient between the number of moles of solutes and the volume of the solution:
Molarity is expressed in units .
In this case:
- number of moles of solute= 2.1 moles
- volume= 7.3 liters
Replacing:
Molarity= 0.29
<u><em>The molarity of the solution is 0.29 </em></u><u><em></em></u>
