The way that you can determine what type of mineral it is by checking their physical property and doing different methods to determine what type of mineral it is.

Do a scratch test on a ceramic plate to determine the streak color. Use Mohs hardness scale to determine the hardness. Try to identify its cleavage. Determine if the mineral has any kind of shine or luster. Find out if it is magnetic, if it has an odor. Color, alone, usually is not going to be enough to identify by.

How many grams of mgo are produced during an enthalpy change of -231 kj ?
SCORPION-xisa [38]

The reaction for the formation of MgO(s):

2 Mg (s) + O2(g) -à 2MgO(s)                     ΔH = -601.24 kJ/mol

<span>The enthalpy information is taken from: http://webbook.nist.gov/cgi/inchi?ID=C1309484&Mask=2</span>

From the equation and with an enthalpy change of -231 kJ:

-231 kJ * 2 mol Mg * (1/-601.24 kJ/mol) = 0.76841 mol Mg

Then, with the molar mass of MgO = 40.3,

0.76841 mol Mg *(2 mol MgO/2 mol Mg)* 40.3 g/mol MgO = <span>30.967 g MgO</span>

FrozenT [24]

For any spontaneous process, universe entropy intensifies is known as the second law of thermodynamics.

<h3>What is entropy?</h3>

Entropy is defined as the degree of randomness or disorderliness of a system.

The entropy of a system generally increases for any spontaneous process.

This is according to the second law of thermodynamics.

In conclusion, the entropy of a system is the a measure of randomness of the system.
