False, because water vapor, water vapour or aqueous vapor, is the gaseous phase of water. It is one state of water within the hydrosphere. Water vapor can be produced from the evaporation or boiling of liquid water or from the sublimation of ice. Unlike other forms of water, water vapor is invisible.
Explanation:
<h3>The mixture in which the particles of the components of solute and solvent are equally mixed is called homogeneous mixture. </h3>
Answer:
About 7.89g/cm^3, I think.
Explanation:
Find the volume. Divide the mass by the volume.
Answer:
atom ion
Explanation:
When an atom gains/loses an electron, the atom becomes charged, and is called an ion.
Answer:

Explanation:
We want to find the new volume given the temperature, so we use Charles's Law. This states the volume of a gas is directly proportional to the temperature. The formula is:

We know the original volume is 20.0 liters and the temperature is 23.0 degrees Celsius. The temperature changes to 45.0 degrees Celsius, but we don't know the new volume. Substitute the known values into the formula.

We are solving the new volume, so we need to isolate the variable V₂. It is being divided by 45.0 degrees Celsius. The inverse of division is multiplication, so we multiply both sides by 45.0 °C.


The units of degrees Celsius cancel.


If we round to the nearest hundredth, the 0 in the thousandth place tells us to leave the 3.

The new volume of the balloon is approximately <u>39.13 Liters.</u>
