Describe how you would obtain a beaker of pure water from salty water
Maslowich

Answer:

You can boil or evaporate the water and the salt will be left behind as a solid. If you want to collect the water, you can use distillation. This works because salt has a much higher boiling point than water. One way to separate salt and water at home is to boil the salt water in a pot with a lid.

The combustion of 14 grams of co according to the reaction co(g) ½o2(g) co2(g) 67.6 kcal gives off how much heat?
Irina18 [472]
The balanced reaction that describes the reaction between carbon monoxide and oxygen to produce carbon dioxide is expressed co(g)+ ½o2(g) <span>→ </span>co2(g). The heat of combustion is 67.6 kcal per mole CO. We are given with 14 grams CO. Convert this to mole equal to 0.5 mole. Hence the total heat is 33.8 kcal.

3. How many molecules are in 2.10 moles of H2O?
AnnZ [28]

Answer:

<h2>1.264 × 10²⁴ molecules</h2>

Explanation:

The number of molecules can be found by using the formula

N = n × L

where n is the number of moles

N is the number of entities

L is the Avogadro's constant which is

6.02 × 10²³ entities

From the question we have

N = 2.10 × 6.02 × 10²³

We have the final answer as

<h3>1.264 × 10²⁴ molecules</h3>

Hope this helps you
