How many mols of chlorine are in 120g of chlorine gas

xz_007 [3.2K]

Answer:

Number of moles of chlorine = 3.38 mol

Explanation:

Given data:

Mass of chlorine = 120 g

Moles of chlorine = ?

Solution:

Formula:

Number of moles = mass/molar mass

Molar mass of chlorine = 35.5 g/mol

Now we will put the values in formula.

Number of moles = 120 g/ 35.5 g/mol

Number of moles = 3.38 mol

Are ions of alkali metals larger or smaller than ions of alkaline earth metals from the same period

PtichkaEL [24]

Because size of an atom INCREASES from top to bottom and DECREASES from left to right on the periodic table. If to elements are in the same period they can't increase in size based on the up or down trend. Instead, notice that Alkali Metals are LEFT of Alkaline Earth Metals. Therefore, the Alkali Metal will be larger than the Alkaline Earth Metals.

A kinetics experiment is set up is set up to collect the gas that is generated when a sample of chalk consisting primarily of so

inn [45]

Answer:

Correct option -D

Explanation:

Here, A kinetics experiment is set up is set up to collect the gas that is generated from the cacarbonate and methanoic acid.

Among the given conditions, decreasing the particle size of calcium carbonate only increases the production of gas.

Smaller particles of reactant increases the surface area then followed by rate of reaction will be increases it leads to increases the production of gas.

Therefore, the suitable experimental condition most likely to increase the gas production is-

Decreasing the particle size of the $CaCO_{3}$ by grinding it into a fine powder.

Hence, correct option -D.
