Chemistry
1 answer:
Anna007 [38]3 years ago
6 0

Answer:

See Explanation

Explanation:

We must first convert the gas pressures to a common unit. I choose to convert all pressures to kiloPascal.

Since;

1 kilopascal = 7.501 torrs

X. =1900tor

X= 1900 × 1/7.501

X= 253.3 Kpa

Since 1 PSI =6.895 kilopascals

132.3PSI = 132.3 × 6.895/1

= 912.2 Kpa

Total pressure = 303.9kPa + 912.2 Kpa + 253.3 Kpa = 1468.8 kPa

For first gas;

303.9/1468.8 × 100 = 20.7%

For second gas;

912.2/1468.8 × 100 = 62.1%

For the third gas;

253.3/ 1468.8 × 100 = 17.2%

Which two solutions, when mixed together, will undergo a double replacement reaction and form a white, solid substance?
IceJOKER [234]

AgNO_3 + KCl → AgCl + KNO_3 undergo a double replacement reaction and form a white, solid substance. Hence, option B is correct.

<h3>What is a double replacement reaction?</h3>

A double replacement reaction is a type of chemical reaction that occurs when two reactants exchange cations or anions to yield two new products.

Double-replacement reactions generally occur between substances in aqueous solution. In order for a reaction to occur, one of the products is usually a solid precipitate, a gas, or a molecular compound such as water.

AgNO_3 + KCl → AgCl + KNO_3 undergo a double replacement reaction and form a white, solid substance.

Hence, option B is correct.
