Answer:
a. add a little distilled water to see which layer the water adds to
Explanation:
The problem tells us to keep in mind two major aspects of the test: It has to be <em>simple</em>, as well as <em>non-destructive</em>:
- Adding distilled water can be made in under a minute, without requiring specialized laboratory equipment, unlike IR.
- It is also non-destructive, because the contents on either layer won't change due to the added distilled water.
Answer is: A. solute
.
Solvation is the interaction of solvent (in this example water) with molecules or ions (in this example carbon dioxide)) in a solute.
Solvent (usually a liquid, but can also be a solid or a gas) is a substance that dissolves a solute (dissolved in the solvent).
Solvent is always the same state of matter as the solution. In this example, soft drink is a liquid, so water is a solvent.
The expected outcome would be A. The reaction will speed up after adding a catalyst to a chemical reaction.
On the first one it is supposed to be 18. when you have a +1 charge you subtract it once. how i got 18 tho was from the protons. there was 19 so i subtracted that with 1 and got 18. hope that helped! :)
btw i’m not the best at explaining, i’m sorry :/
Balanced Equation is
4H2SiCl2+4H2O → H8Si4O4 + 8HCl
