Explanation:

It is known that density is amount of mass present in per unit volume of the substance.

Mathematically,      Density = \frac{mass}{volume}

It is given that mass is 6.32 \times 10^{2} g and density is 1.29 g/L.

Therefore, calculate the volume by putting the given values into the above formula as follows.

                Density = \frac{mass}{volume}

                  1.29 g/L = \frac{6.32 \times 10^{2} g}{volume}

              volume = 489.92 L

Thus, we can conclude that volume of the air is 489.92 L.

4.90× 10^2 L

I am guessing that the mass of the air is 6.32 × 10^2 <em>g</em>. Then,

Volume = 6.32 × 10^2 g × (1 L/1.29 g) = 4.90× 10^2 L

Match the following. 1. A mixture that does not have a uniform composition and the individual components remain distinct. polar
Ganezh [65]

Answer:

Explanation:

1. A mixture that does not have a uniform composition and the individual components remain distinct.

HETEROGENEOUS

An heterogeous mixture is a mixture with components in different phases.

2. A mixture that does have a uniform composition throughout and is always in the same state.

HOMOGENOUS

Homogenous mixtures have just one phase that is uniform all through.

3. A substance that will not dissolve in a solvent.

INSOLUBLE

When a solute cannot dissolve in a solvent to form a solution, we say it is insoluble.

4. A homogeneous mixture

SOLUTION

Solutions are made up of homogenous mixtures solute and solvent.

5. A molecule with no internal charge variation due to bonding.

NON-POLAR

Even distribution of charges especially between species whose electronegativity difference is 0 would lead to the formation of a non-polar compound. Here,

6. A molecule with an uneven distribution of charge due to unequal sharing of electrons during bonding

POLAR

Unequal sharing of electrons forms a polar compound. The more electronegative attracts the shared electron to itself and there is separation of charges. This leads to polarity.

7. A solution which has dissolved as much solute as it can at a particular temperature.

SATURATED

A saturated solution cannot dissolve more solute beacuse it contains enough solute as it can dissolve at a temperature.

8. A solution which is still able to dissolve solute.

UNSATURATED

An unsaturated solution is able to dissolve more solute.

(environmental science) 1.which aspects of climate are most important to forest ecosystems?
mamaluj [8]
Probably the CO2 concentration. If the earth gets warmer by rising greenhouse gases (one of which is CO2), the amount of rainfall and precipitation increases. I am not an expert, but that's my first guess.
