Answer:

3.- The same

Explanation:

1.- In the reactants you need to calculate the charges that you have:

2 Al(s) = zero, because the aluminum is in it based formed (that mean without charge).

3 Cu2+ = 3 x 2+ = 6+ That is the total positive charges that copper collaborate in this reaction.

2.- Then calculate the charges on the products:

2 Al3+ = 2 x 3+ = 6+ charges from the aluminum.

3 Cu(s) = zero, because the copper in this case is in the base form

3.- In this way, the charges at the begging (6+) and at the end (6+) are the same.

Match the action to the effect on the equilibrium position for the reaction N2(g) + 3H2(g) ⇌ 2NH3(g). (3 points)
AleksandrR [38]

Answer:

1. Adding hydrogen gas, b. shift to the right
2. Adding a catalyst, c. No effect
3. Decreasing the pressure, a. shift to the left

Explanation:

Hydrogen gas can be rewritten as H2. Whenever you add something to an equilibrium expression, it will shift to whichever side does not have this. So, since the reactant side has 3 moles of H2, adding more H2 to the reaction will shift to the products side, since there is no H2 there.


Adding a catalyst has no effect on equilibrium reactions.

When decreasing the pressure, equilibrium will shift to the side with the greater number of moles of gas. In this case, there are 4 moles of gas on the left, and 2 on the right, so it would shift to the left.

tino4ka555 [31]

Answer:

The correct answer is propane.

Explanation:

The movement of chemicals follows numerous standards, which indicate that each trailer must contain an ID number identifying the chemical being moved. This is necessary because before possible accidents and leaks we must know the measures to be taken before a leak.

Have a nice day!

The half reaction of an oxidation reduction reaction shows that iron gains electrons. what does this electron gain mean for iron
chubhunter [2.5K]

Answer: The correct option is C.

Explanation:

Oxidation reactions are a type of chemical reactions in which a substance looses electrons and forms positive charge. The substance undergoing this reaction is being oxidized.

A\rightarrow A^++e^-

Reduction reactions are a type of chemical reactions in which a substance gains electrons and forms negative charge. The substance undergoing this reaction is being reduced.

A^++e^-\rightarrow A

For the half reaction in which iron gains electrons means that iron is getting reduced.

Hence, the correct option is C.

How many moles of O2 are produced in the decomposition of 24 g of water in the
Natali5045456 [20]
M of water = 2(1) + 16 = 18 g/mol
n of water = 24g/(18g/mol) = 4/3 mol
n of H2O : n of O2 = 2 : 1
2:1 = 4/3 : x
x = (4/3)/2 = 2/3 mol of O2
