I believe you mean 1.02*10^24 so I did
1.02*10^24/(6.02*10^23) * 54.938. I got d) 9.31*10^1 g as my answer.
Answer:
All liquid glow products depend on a chemical process known as CHEMILUMINESCENCE to produce their light. Chemiluminesence is a chemical reaction that causes a release of energy in the form of light. To produce this light the electrons in the chemicals become excited and rise to a higher energy level.
To utilise this process glowsticks contain two liquids; hydrogen peroxide and tert-butyl alcohol. When mixed together it is these liquids that create the glow. Fluorescent dyes are also used in the alcohol to alter the colour of the light emitted.

Explanation:
mass = Moles * molar mass
molar mass of BaSO4 = 112+32+64= 208
= 1.72*208 = 357.76
Answer:
A) vinegar-acidic Baking soda-basic Tomato juice-acidic Sugar-neutral.
Explanation:
Hello,
In this case, it is widely acknowledged that vinegar is a diluted and processed form of acetic acid which is of course acidic as well as tomato juice which has a pH of about 4.2. Baking soda, which is chemically known as sodium bicarbonate has a pH greater than 7, for that is reason it is basic. Finally, sugar, is known by its neutrality, for which its pH is about 7, for that reason it is neutral. In such a way, answer is A) vinegar-acidic Baking soda-basic Tomato juice-acidic Sugar-neutral.
