Answer:

68 grams is the maximum amount of KCl that can be dissolve in 200 g of water.

Explanation:

Let the maximum amount of KCl dissolved in water be x

Solubility of KCl in water = 34g /100 g

This means that  34 g of KCl can be dissolved in 100 g of water at 20°C

Maximum amount of KCl dissolved in  1 g of water = \frac{34}{100} g

Maximum amount of KCl dessolbved in 200 g of water :

\frac{34}{100}\times 200=68 g

68 grams is the maximum amount of KCl that can be dissolve in 200 g of water.

Inessa05 [86]

Answer:

The correct option is: bent 109°

Explanation:

Covalent molecules are the molecules in which the atoms are linked by covalent bonds. The electrons involved in the formation of a covalent bond are known as shared pair or <u>bond pair of electrons</u>.

The three-dimensional arrangement of the atoms of a molecule in space is known its molecular structure or geometry.

<u>Given molecule</u>: XY₂, having two lone pairs around the central atom X.

Since the molecule XY₂ has <u>two lone pairs</u> and <u>two bond pairs</u> of electrons. Therefore according to the VSEPR theory, the given molecule has a <u>bent molecular geometry with 109° bond angle.</u>

<span>There is only one formula to use and we should assume ideal gas. This equation is: PV=nRT. For the following questions manipulate this equation to get the answer.
 1. n = PV/RT = (249*1000 Pa)(15.6 L)(1 m^3/1000 L)/(8.314 Pa-m^3/mol-K))(21+273) = 1.59 mol
 2. P = nRT/V = (1.59)(8.314)(51+273)/(15.6/1000)(1000) = 274.55 kPa
 3. Since the answer in #2 is more than 269 kPa, then the tires will likely burst. 4. Reduce pressure way below the limit 269 kPa.</span>
