What do you put in the calculator to get the molar mass of Mg3P2
olga55 [171]

Input the atomic masses of Mg and P to give 134.84g/mol

Explanation:

The molar mass of a substance (atom or molecule or compound) is the mass in grams of one mole of the substance:

When dealing with an element the molar mass is the relative atomic mass expressed as g/mol.

For compounds, you add the atomic masses of the component atoms and you sum up.

You simply input the atomic mass of 3 atoms of Mg and 2 atoms of P

Atomic mass of Mg = 24.3g/mol

                             P = 30.97g/mole

Molar mass of Mg₃P₂ = 3(24.3) + 2(30.97) = 134.84g/mol

The lowest value of the henry's law for methane gas (ch4) will be obtained with __________ as the solvent and a temperature of _
NikAS [45]

The lowest value of the henry's law for methane gas (CH₄) will be obtained with H₂O as the solvent and a temperature of  349 K.

The lowest value of the henry's law for methane gas (CH₄) will be obtained with H₂O as the solvent and a temperature of 349 K.  

Henry's law: This law states that at a constant temperature, the amount of a gas dissolved in a given type and volume of liquid is directly proportional to the partial pressure of that gas that in equilibrium with that liquid.

Mathematically it can be written as:

          C_{g}=k\times P_{g}

So, for the methane gas , lowest value of the henry's law obtained at  349 K and with H₂O as the solvent.

A wildfire can destroy thousands of acres of forest. Explain two positive effects and two negative effects that a wildfire can h
Lynna [10]

Explanation:

Wildfires destroy forests that are great carbon sinks. This means that large amount of carbon dioxide are released back into the atmosphere. Carbon dioxide is a greenhouse gas and this will contribute to global warming.

An advantage is that the wildfire will spur secondary ecological succession. This kind of succession improves the biodiversity of the forest. Biodiversity improves the productivity of the ecosystem.
