Volume will increase. As you put particles back together then it would make it a lot heavier, giving it more volume.

The volume will increase it means more mass is being added to the object or liquid :)

What does it mean when a rock is foliares?
yan [13]
Started out as some other type of rock, but have been substantially changed from their original igneous, sedimentary, or earlier metamorphic form. Metamorphic rocks form when rocks are subjected to high heat, high pressure, hot mineral-rich fluids or, more commonly, some combination of these factors.

Most of the water a vascular plant takes in ______. Goes back into the soil Evaporates in the process of transpiration Is used t
MatroZZZ [7]

Answer:

EVAPORATES IN THE PROCESS OF TRANSPIRATION

Explanation:

Plants takes in water from the soul via it's root system. Small amount of the water are used for growth and metabolism of the plants. Some are used in the process of photosynthesis. The bulk of the remaining are lost through transpiration. This takes place in the stomata of the plants. The stomata are numerous on the leaf surfaces and are guarded by cells which allow for opening and closing of the stomata. Transpiration helps the plants to remove CO2 produced by photosynthesis, cools the plant and also changes osmotic pressure of the plant which allows for the flow of nutrients and water from the root to the leaves, flowers, fruits.

- How many grams are in 4.6 x 1016 molecules of phosphorus trichloride (PCI)?
MariettaO [177]

Answer:

0.0000101 grams.

Explanation:

First of all, use Avogadro's number to convert from molecules to moles.

Avogadro's number is 6.02 x 10^23.

Second of all, to convert from moles to grams, find the substance formula of phosphorus trichloride. After finding the substance formula, then find the molar mass of phosphorus trichloride.

Phosphorus trichloride is PCl3

Now find the molar mass of PCl3

P = 31.0 amu

Cl = 35.5 amu

They are three chlorine atoms and one phosphorus atom. So you do this.

31.0(1) + 35.5(3) = 137.5 g/mol

Now use dimensional analysis to show your work

4.6 x 10^16 grams of PCl3 * 1 mol/ 6.02 x 10^23 * 137.5 g/mol / 1 mol

The grams and the moles cancel out.

So now do [(4.6 x 10^16) / (6.02 x 10^23)] x 137.5

and you will get 0.000010507

4.6 has the fewest digits which is 2.

So use sig figs and the answer rounds to the nearest millionths.

0.000010507 rounds to 0.0000101

So the final answer is 0.0000101 grams(don't forget the units)

Hope it helped!
