If a gas is cooled from 315K to 231K and the volume is kept constant, what would the final pressure be if the original pressure
goblinko [34]

Answer:

455.4 mmHg

Explanation:

To solve this problem we can use <em>Gay Lussac's Law</em>, which describe the temperature and pressure of a gas, at constant volume and composition:

  • P₁T₂ =  P₂T₁

In this case:

  • P₁ = 621 mmHg
  • P₂ = ?
  • T₁ = 315 K
  • T₂ = 231 K

We <u>input the data</u>:

  • 621 mmHg * 231 K = P₂ * 315 K

And <u>solve for P₂</u>:

  • P₂ = 455.4 mmHg

SCORPION-xisa [38]

Answer:

In order of basicity we have

1. Soda pop (Least basic Normally called acidic)

2. Orange juice

3. Milk

4. Blood (slightly basic)

5. Hand soap

6. Drain cleaner (Highly basic)

Explanation:

Orange juice; the pH of orange juice is in the 3.3 to 4.2 range

Milk; the pH of milk about 6.5 to 6.7

Blood; the blood pH is around 7.35 to 7.45

Hand soap with contents such as ammonium hydroxide is basic, its  pH is about 9-10

Drain cleaner contains baking soda or sodium bicarbonate which basic with a  pH of 12 to 14

Soda pop pH of soda pop is in the range of 2.34 to 3.10. It contains carbonated water with a pH of 3–4, making it mildly acidic.

Arranging the above listed in order of increasing basicity, we have

1. Soda pop

2. Orange juice

3. Milk

4. Blood

5. Hand soap

6. Drain cleaner

How many grams of Cl2 are consumed to produce 12.0 g of KCl?
Alla [95]

The reaction is:

Cl2 + 2 KBr --> 2 KCl + Br2

Moles of KCl is

n = m /M = 12 /74 = 0.16 mol

As, twice the moles of KCl is producing from 1 mol of chlorine

mole of Cl2 = 0.16 /2 = 0.08 mol

Mass of Cl2

m /70 = 0.08 = 5.6 g

Hence, 5.6 g mol Cl2 consumed to produce KCl
