What mass of CaCl2 (in g ) should the chemist use?

solmaris [256]

The mass of the solute required is 250.25 g.

<h3>What is the mass of the solute?</h3>

We know that the number of moles of the solute can be used to obtain the mass of the solute that is required. We can now try to find the mass of the solute that is required.

Concentration of the solution = 0.350M

Volume of the solution = 6.5 L

Number of moles of the solute = 0.350M * 6.5 L

= 2.275 moles

We now have the mass of the solute as;

2.275 moles * 110 g/mol

= 250.25 g

Th measured mass of the solute that we would have to use is 250.25 g.

When cac2 reacts with water, what carbon-containing compound forms? when reacts with water, what carbon-containing compound form

meriva

Notice that each reactant is made up of two elements. To predict the products, all you have to do is interchange the combination of the two reactants while taking note that metal comes first, followed by nonmetals. With that being said, the reaction would be:

CaC₂ + 2 H₂O --> C₂H₂ + Ca(OH)₂

<em>So, the answer is C₂H₂.</em>

What is a major problem with CFCs?

oksian1 [2.3K]

The major problem with CFCs is that It is a greenhouse gas, Option A is correct.

Chlorofluorocarbons (CFCs) are nontoxic, nonflammable chemicals containing atoms of carbon, chlorine, and fluorine.

They are used in the manufacture of aerosol sprays, blowing agents for foams and packing materials, as solvents, and as refrigerants.

CFCs are classified as halocarbons, a class of compounds that contain atoms of carbon and halogen atoms

The major problem with CFC's is that they are green house gases

It destroys ozone in the upper atmosphere (stratosphere).

CFCs can produce more than 10,000 times as much warming, pound for pound, once they are in the air.

It is not only because of their dramatic warming potential but also

They were found to be the primary cause of the rapidly escalating destruction of the Earth’s ozone layer,

which protects the planet from dangerous, cancer-causing levels of ultraviolet radiation.

Therefore The major problem with CFCs is that It is a greenhouse gas, Option A is correct.
