Chemistry

Ede4ka [16]3 years ago
6 0

The family on the periodic table that has a filled outer energy level is VIIIA. The answer is letter D. They are also called the noble gases or inert gases. They are virtually unreactive towards other elements or compounds. They are found in trace amounts in the atmosphere. Their elemental form at room temperature is colorless, odorless and monatomic gases. They also have full octet of eight valence electrons in their highest orbitals so they have a very little tendency to gain or lose electrons to form ions or share electrons with other elements in covalent bonds.

What is the maximum amount of kci that can dissolve in 200 g of water?
Anuta_ua [19.1K]

The solubility of KCl in water is 34.2 g per 100 g of water.

That means at STP, 34.2 g of KCl is dissolved in 100 g of water.

So, 100 g of water dissolved= 34.2 g of KCl

1 g of water dissolved=\frac{34.2 g of KCl}{100}

200 g of water dissolved=\frac{34.2 g of KCl}{100}\times 200

=68.4 g of KCl

So, the maximum amount of KCl that can dissolve in 200 g of water is 68.4 g.

sveticcg [70]

Answer:  You meant in constant temperature?

Because temperature is not mentioned at the beginning.

I suppose temperature remains constant, otherwise

there is no enough data for solving the problem

Explanation: According Boyle´s law in constant temperature

pV = constant.  So p1V1 = p2V2   and pressure p2 = p1V1 /V2

= 88 atm · 18 l / 12 l =  132 atm.
