1. The mass of the water is 8.13 g.

2. The density of the water is 1 g/mL

Density is related to mass and volume by the following equation:

<h3>Density = mass / volume </h3>

<h3>1. Determination of the mass of water. </h3>

Mass of cylinder = 56.98 g

Mass of cylinder + water = 65.11 g

<h3>Mass of water =? </h3>

<h3>Mass of water = (Mass of cylinder + water) – (Mass of cylinder) </h3>

Mass of water = 65.11 – 56.98

<h3>Mass of water = 8.13 g</h3>

Thus, the mass of the water is 8.13 g

<h3>2. Determination of the density of water. </h3>

Mass of water = 8.13 g

Volume of water = 8.15 mL

<h3>Density of water =? </h3>

Density = mass / volume

Density = 8.13 / 8.15

Density of water = 0.998 g/mL

<h3>Density of water ≈ 1 g/mL </h3>

Therefore, the density of the water is 1 g/mL

tekilochka [14]

The next test would be the lime water test.

Explanation:

If placing the gas in lime water will turn the solution milky, then the gas is most probably carbon dioxide, the lime water (Ca(OH)₂) turns milky due to the formation of solid CaCO₃ that is insoluble after reaction with carbon dioxide.

Carbon dioxide also puts out the flame in the splint test because it does not support combustion.

What term is used to describe the energy level of any level higher than the ground state of a particle?
Xelga [282]

Answer:

B. Excited state

Explanation:

Energy levels higher than the ground state are called the excited states. This concept is based on the premise that electrons can move round the nucleus in certain permissibe orbits or energy levels.

The ground state is the lowest energy state available to the electron. This is usually the most stable state.

The excited state is any level higher than the ground state. An electron  in an energy level has a definite amount of energy associated with it at that level.

is a secondary resonance stabilized carbocation more or less stable than a nonrez stabilized tertiary carbocation
olasank [31]
In a secondary carbocation, only two alkyl groups would be available for this purpose, while a primary carbocation has only one alkyl group available. Thus the observed order of stability for carbocations is as follows: tertiary > secondary > primary > methyl.
