What is happening within the system when it is at equilibrium in terms of concentration, reactions that occur, and reaction rates? 2CH4(g) <--> C2H2(g) + 3H2(g)

Answers

Answer 1

Answer:

Answer and Explanation:

It is worthy to be mentioned that the equilibrium in this reaction is dynamic equilibrium.

In terms of concentration: the concentration of reactants (CH4) and products (C2H2 & H2) do not change and be constant at the equilibrium, that 2 moles of CH4 give one mole of C2H2 and 3 moles of H2.
In terms of reactions that occur: the reactions that occur at the equilibrium are the forward and the reverse reaction. The forward reaction: 2CH4 → C2H2 + 3H2 and the reverse reaction: C2H2 + 3H2 → 2CH4.
In terms of reaction rates: At equilibrium the rate of the forward reaction is equal to the rate of the reverse reaction.

Answer 2

Answer:

Answer:

In a chemical reaction equilibrium is in the state which reacts with both products and reactants. Both reverse and forward are happening and both reaction rates forward and reverse are equal.

So basically A goes to U, G goes to C, C goes to G, and U goes to A. So for example, the first one is phen.(A A G). You would take the opposites of these numbers as explained before. So the mRNA of that sequence would be UUC.

Potassium has an atomic number of 19.Which of a potassium atom's electrons are its valence electrons?
Select one:
a. Those in the third shell from the nucleus.
b. Those in the second shell from the nucleus.
c. Those in the outermost shell.
d. Those in the innermost shell.

Answers

The correct response would be C. Those in the outermost shell, and of highest electron energy are the valence electrons for potassium.

Explanation:

Hydrogen peroxide

Hydrogen peroxide is a chemical compound with the formula H₂O₂. In its pure form, it is a very pale blue liquid, slightly more viscous than water. It is used as an oxidizer, bleaching agent, and antiseptic. Concentrated hydrogen peroxide, or "high-test peroxide", is a reactive oxygen species and has been used as a propellant in rocketry. Its chemistry is dominated by the nature of its unstable peroxide bond.

Water

Water is an inorganic, transparent, tasteless, odorless, and nearly colorless chemical substance, which is the main constituent of Earth's hydrosphere and the fluids of all known living organisms. It is vital for all known forms of life, even though it provides no calories or organic nutrients. Its chemical formula is H₂O, meaning that each of its molecules contains one oxygen and two hydrogen atoms, connected by covalent bonds. Two hydrogen atoms are attached to one oxygen atom at an angle of 104.45°.
