Answer:

Find the steps and explanation below.

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.

If you have a density of 100 kg/L and a mass of 1000 g what is the volume (please explain)
olchik [2.2K]

Answer:  Volume =  0.01L

Explanation:

The density of a substance is given by; Density =  Mass / Volume.

In this question, Mass = 1000g, Volume = ? and Density = 100 Kg/L

For the units to be uniform, we convert 1000g to Kg = 1Kg

Therefore, Volume = Mass / Density =  1Kg / 100Kg/L = 0.01L

Describe what happened when Ag+ combined with Na2CO3. what does this indicate?
lisabon 2012 [21]
When Ag+ is combined with Na2CO3, the substances formed are Ag2CO3 and Na+. In this case, Ag performs single substitution over the element Na to form another set of substances. There are other types of reactions like double displacement, decomposition, etc.

The rate constant for the decomposition of nitrogen dioxide NO2(g) LaTeX: \longrightarrow⟶ NO (g) + 1/2 O2(g) with a laser beam
aleksley [76]

Answer :

The time taken by the reaction is 19.2 seconds.

The order of reaction is, second order reaction.

Explanation :

The general formula to determine the unit of rate constant is:

(Concentration)^{(1-n)}(Time)^{-1}

Unit of rate constant                           Order of reaction

Concentration/Time                                        0

Time^{-1}                                                              1

(Concentration)^{-1}Time^{-1}                                 2

As the unit of rate constant is M^{-1}min^{-1}. So, the order of reaction is second order.

The expression used for second order kinetics is:

kt=\frac{1}{[A_t]}-\frac{1}{[A_o]}

where,

k = rate constant = 1.95M^{-1}s^{-1}

t = time = ?

[A_t] = final concentration = 0.97 M

[A_o] = initial concentration = 2.48 M

Now put all the given values in the above expression, we get:

1.95\times t=\frac{1}{0.97}-\frac{1}{2.48}

t=0.32min=0.32\times 60s=19.2s

Therefore, the time taken by the reaction is 19.2 seconds.
