Explanation:

A. Kids make slime following these basic steps;

1. In a bowl, is 1/4 cup of water is added to 1 oz. of glue. Add coloring if you wish to.

2. 1/4 cup of Borax solution, also known as Sodium Tetraborate is added to the mixture and gradually stirred.

3. The mixture is kneaded with the hands to ensure a smooth consistency.

4. Water remnants are discarded and the slime is stored in a plastic bag and kept in the fridge.

B.

What each ingredient does

Polyvinyl acetate present in the glue acts as a liquid polymer.

Borax binds the liquid polymers together.

Water eases the mixing process

C.

If lesser ingredients are used, the slime will not have its characteristic slimy nature. If excess of the ingredients are used, the slime becomes very sticky.

 stoichiometry of C</span>₄H₁₀ to O₂ <span>is 2:13
stoichiometry applies to the molar ratio of reactants and products. Avagadros law states that volume of gas is directly proportional to number of moles of gas when pressure and temperature are constant.
 Therefore volume ratio of reactants is equal to molar ratio, volume ratio of C</span>₄H₁₀ to O₂<span> is 2:13

John has a solution. It turns yellow when he adds red cabbage juice. Predict what colour the solution would turn if he added hib
FrozenT [24]

As the solution turns yellow when re cabbage juice indicator  is added it implies that its base solution so the color of the  solution when hibiscus flower juice added is dark grey to green.

when hibiscus indicator added Anywhere from dark pink to pale pink usually indicates an acid, while dark gray to green colors usually indicate a base.

Dark blue should be the color of  red cabbage indicator. The cabbage indicator's color will shift to red or pink if the solution is an acid, and to green or yellow if the solution is a base. In the event that the test solution is neutral, it will stay purple or blue
