Metamorphic rocks with a non-foliated texture show metamorphic change that involves ____.

matrenka [14]

Answer:

b. growth in the size of the mineral grains

Explanation:

Non-foliated texture shown by a metamorphic change is depicted by growth in the size of the mineral grains.

Examples of non-foliated metamorphic rocks are quartzite and marble.
In these metamorphic rocks, mineral grains are not aligned with their long axis.
Non-foliated texture occurs under high temperature and low pressure conditions.
As minerals are able to grow, the size can be used to show a metamorphic change.

A sample of oxygen has a volume of 128 milliliter at a pressure of 500.0 mmhg calculate the volume this sample would occupy at s

leva [86]

Answer:

84.2mL

Explanation:

The following data were obtained from the question:

Initial volume (V1) = 128mL

Initial pressure (P1) = 500mmHg

Final pressure (P2) = stp = 760mmHg

Final volume (V2) =..?

Thus, the new volume of the gas can be obtained by using the Boyle's law equation as follow:

P1V1 = P2V2

500 x 128 = 760 x V2

Divide both side by 760

V2 = (500 x 128)/760

V2 = 84.2mL

Therefore, the new volume of the gas is 84.2mL

All molecules are made of similar type of atom true or false

vichka [17]

Answer:

False

Explanation:

Not all molecules are compounds, since some molecules, such as oxygen gas (above image of molecule of-O2) or ozone (O3), consist only of one element or type of atom. Water is also a molecule because it is made from atoms that have been chemically combined.
