How many formula units make up 30.4 g of magnesium chloride (mgcl2)?

ahrayia [7]

There are 1.923×10^23 formula units in 30.4g mgcl2

molar mass of mgcl2= 95.211g/mol
magnesium= 24.305g/mol
chlorine= 35.45g/mol times 2
24.305+(35.45*2)= 95.211g/mol

sample divided by molar mass times Avogadro's number gives u the formula units

30.4÷ 95.211= .31929
.3193*6.022=1.9288

The process that is the opposite of sublimation is called deposition. Use the example of frost formation to infer why this proce

Vedmedyk [2.9K]

Answer:

See explanation

Explanation:

Sublimation refers to the movement of molecules directly from solid into the vapor or gas phase while deposition refers to the movement of molecules directly from the gas phase into the solid phase. The two are opposite to each other.

Frost is formed in a situation where a substance cools to a temperature that is lower than its dew point. In this situation, the vapour is directly deposited on a surface to form a frost without passing through a liquid phase. Hence the name, deposition.

The equilibrium-constant expression depends on the ________ of the reaction. Group of answer choices temperature stoichiometry m

slavikrds [6]

Answer:

temperature and mechanism

Explanation:

Arrhenius equation gives us the idea about the factors affecting equilibrium constant.It is given as:

where k=equilibrium constant

A=pre-exponential factor

$E_{a}$ =Activation energy

T=temperature

R=Universal gas constant

<h3>It is clear that k depends only on temperature and activation energy.</h3>

Activation energy of a reaction is different for different mechanisms or pathways.Hence k depends on both temperature and mechanism.
