Write and balance the equation for the combination of ammonia gas with solid copper (II) oxide to produce copper metal, nitrogen

Katena32 [7]

Explanation :

The balanced chemical reaction will be,

$3CuO(s)+2NH_3(g)\rightarrow 3Cu(s)+N_2(g)+3H_2O(l)$

By the stiochiometry, 3 moles of solid copper(II)oxide react with 2 moles of ammonia gas to give 3 moles of copper metal, 1 mole of nitrogen gas and 3 moles of liquid water.

The states of matter of each elements and compound is,

Copper(II)oxide is in solid state

Ammonia is in gaseous state

Copper metal is in solid state

Nitrogen is in gaseous state

Water is in liquid state

A female bear leaves her bear cubs in their den to go out in search of food. She travels one mile in 30 minutes, heading east. S

Vinil7 [7]

Answer:

Points of acceleration:

1. When female bear goes quickly

2. After becoming tired, when she becomes slow

3. When she changes direction from east to north

4.When she slows down when she reaches the river bed

5. When she turns around

6.When she increases speed to travel southwest to return home

7. When she comes to a stop at home

Explanation:

1. When she is going quickly she is increasing her velocity thus positively accelerating

2. When she becomes slow, she is having negative acceleration.

3. When there is a change in direction of velocity there is an acceleration.

4. Again negative acceleration when she comes to a stop at the river bed

5. Turning around to the southwest direction requires acceleration

6. To increase the velocity to reach home, positive acceleration

7. To decrease the velocity to stop upon reaching home, negative acceleration

A sample of 0.200 moles of nitrogen occupies 0.400 L. Under the same conditions, what number of moles occupies 1.200 L

IRISSAK [1]

The number of mole of nitrogen that occupies 1.2 L under the same condition is 0.6 mole

<h3>Data obtained from the question </h3>

Initial mole (n₁) = 0.2 mole
Initial volume (V₁) = 0.4 L
Final volume (V₂) = 1.2 L
Final mole (n₂) =?

<h3>How to determine the final mole </h3>

The final mole can be obtained by using the ideal gas equation as illustrated below:

PV = nRT

Divide both side n

PV / n = RT

Divide both side by P

V / n = RT / P

RT / P = constant

V / n = constant

Thus,

V₁ / n₁ = V₂ / n₂

0.4 / 0.2 = 1.2 / n₂

2 = 1.2 / n₂

Cross multiply

2 × n₂ = 1.2

Divide both side by 2

n₂ = 1.2 / 2

n₂ = 0.6 mole
