The density of the unknown liquid has a mass of 7.553g is 0.7553 g/ml
<h3>What is density?</h3>
Density is the measurement of how tightly a material is packed together.
Given data:
Weight =7.553g
Volume = 10.0ml
Density =
Density =
Density = 0.7553 g/ml
Hence, the density of the unknown liquid has a mass of 7.553g is 0.7553 g/ml.

The right answer is
Table A Organic solvent
No Perfume No Fuel No Anesthetic No Adhesive Yes
A solution's pH will be a number between 0 and 14. A solution with a pH of 7 is classified as neutral. If the pH is lower than 7, the solution is acidic. When pH is higher than 7, the solution is basic. These numbers describe the concentration of hydrogen ions in the solution and increase on a negative logarithmic scale. For example, If Solution A has a pH of 3 and Solution B has a pH of 1, then Solution B has 100 times as many hydrogen ions than A and is therefore 100 times more acidic.
Answer:
A. unexpected change in odor
Explanation: Common physical changes include melting, change of size, volume, color, density, and crystal form. Example the classic baking soda and vinegar reaction provides evidence of a chemical change due to the formation of a gas and a temperature change.
D:
When electrons are gained, the charge of the atom decreases.
When you are given an atom with a charge, the oxidation of that atom is the charge. So by going from a Cr^3+ (Oxidation Number = 3) to a Cr^2+ (Oxidation Number = 2), the Oxidation Number thus decreases.
