Answer:

A. Charles's law

Explanation:

Charles's law states that volume of given gas is directly proportional to the temperature at constant pressure. Directly means if one increases, the other also increases. If temperature of a gas increases, the particles of gas molecules start expanding. Due to expansion, the particles occupy more space and thus volume of the gas molecules increased.

The percentage yield of the following reaction is 85 %. 2 Al, +31--> 2 AICI. How many grams of AICI, will be actually obtaine
Readme [11.4K]

Answer:

Assuming the product is AlCl3

Assuming its 1008 g of metalic Al

It will yeld 4234 g of aluminium chloride.

Explanation:

Al molar mass is 26.98 g/mol, so in 1008 g of Al there is 37.36 mols of Al

The stoichometry ratio between Al and AlCl3 is 1:1, so 37.36 mols of Al would form 37.36 mols of AlCl3 if the reaction were complete, but only 85% yelds, so 1008 g of Al makes up to 0.85x37.36 mols of AlCl3 (31.76 moles)

AlCl3 molar mas is 133.33 g/mol, so 31.76 moles has 4234 g

Which is a Characteristic of a non elecrolyte​
myrzilka [38]

Answer:

A nonelectrolyte is a substance that does not exist in an ionic form in aqueous solution. Nonelectrolytes tend to be poor electrical conductors and don't readily dissociate into ions when melted or dissolved. Solutions of nonelectrolytes do not conduct electricity.

In a titration of 0.35 M HCl and 0.35 M NaOH, how much NaOH should be added to 45.0 ml of HCl to completely neutralize the acid?
Rom4ik [11]
<span>M(HCl) * </span><span>V(HCl) </span>= <span>M(NaOH) * </span><span>V(<span>NaO<span>H)
</span></span></span>
M(HCl) = 0.35
<span>V(HCl) = 45mL
</span>M(NaOH)= 0.35

now, solne for V(NaOH) by putting these values in the above equation.
M(HCl) * <span>V(HCl) </span>= <span>M(NaOH) * </span><span>V(NaOH)</span>

<span>0.35 * 45 = 0.35 * V(NaOH)</span>

<span>V(NaOH) = 45 mL</span>

What is molarity of 50.0 g of mgcl2 dissolved in 150 ml of solution?
Ivahew [28]
To find the molarity of the compound, simply determine the molar mass of MgCl2 and then convert 50 g to moles using the molar mass of the compound. Then convert 150 ml to L = 0.15 L

Then divide the moles amount by the volume in L.
