Which reaction is reversible and could reach dynamic equilibrium?
O A. Burning a wood log
O B. Frying an egg
O C. 3H2 + N2 = 2NH3
O D. 2Mg + 02 → 2Mgo
Answer:
The correct answer is - option C. 3H2 + N2 = 2NH3
Explanation:
If in a chemical reaction the rate of the forward reaction and the rate of reverse reaction are equal, this is called dynamic equilibrium. Due to this equal rate of both side reactions, there is no change in the system. In this type of reaction, the concentration of reactants and products remain constant and the overall reaction is continuous.
Dynamic reactions can be reached by reversible reactions such as 3H2 + N2 = 2NH3 where the concentration of hydrogen and nitrogen and concentration of the ammonia remains constant and rate of the both side are equal.
Answer:
3H2 + N2 = 2NH3

I very sorry for not filling in everything but I have a small trick for you to help you out. So if you read out loud each sentence and put one of the words from the word bank in the sentence only a few will make sense. So if you read the second sentence out loud with one of the words that you have and one of them sounds correct then you fill it in. Also like your paper says one word can be used multiple times.

Calculate the mass of 12.3 moles of MgSO4.
Answer:
614 034 kg
Explanation:
n = m/Mm
m = n * Mm
Mm(MgSO4) = 1 * 24.3 * 1 * 32.1 * 4 * 16 = 49921.92
m = 12.3 * 49921.92
m = 614 034 kg

Answer:
It is rigid.
It has a very high melting point.
Explanation:
It conducts electricity. It is rigid. It has a very high melting point. It is magnetic. It is shiny. It rusts.The two properties that are needed for the metal grill out of the options are its rigidity and high melting point.
The rigidity of the metal grill will enable it to hold materials to be grilled without problems while the high melting point will enable the grill to remain intact at the high temperature required for the successful grilling of certain food materials.
A. 207 kJ
B. 4730 kJ
C. 9460 kJ
D. 414 kJ
Answer:
C = 9460 Kj
Explanation:
Given data:
Mass of copper = 2kg
Latent heat of vaporization = 4730 Kj/Kg
Energy required to vaporize 2kg copper = ?
Solution:
Equation
Q= mLvap
by putting values,
Q= 2kg × 4730 Kj/Kg
Q = 9460 Kj
