Stolb23 [73]

<h3>Answer: <em> Pyruvate dehydrogenase consists of three enzymes: -Pyruvate dehydrogenase, Dihydrolipoyl transacetylase, and Dihydrolipoyl dehydrogenase. The short distance between these enzymes allows channeling of substrates which minimizes the side reactions.</em></h3><h3><em></em></h3>

A mixture containing initially 3.90 mole of NO(g) and 0.88 mole of CO2(g) was allowed to react in a flask of volume 1.00 L at a

Ymorist [56]

Answer:

Equilibrium constant Kc for the reaction will be 1.722

Explanation:

O2(g)+NO(g)→CO(g)+ NO2(g)

0.88 3.9 --- ---

0.88x 3.9-x x x

GIVEN:

0.88X-X= 0.11

⇒ X=0.77

CO2(g)+NO(g) → CO(g) + NO2(g)

0.88 3.9 --- ---

0.88-x 3.9-x x x

= 3.13 0.77 0.77

=0.11

Kc = $\frac{[CO] *[NO2]} {[CO2]*[NO]}$

= ${{0.77}×0.77÷{{0.11×3.13}}$

= 1.722

Prokaryotic cells- plants cells

I am pretty sure that prokaryotic and eukaryotic cells are considered to be living due to the cell theory because the cell theory states that all living things are made of cells.

Answer:

The equation that gives the overall equilibrium in terms of the equilibrium constants K and Ky is K1 = K^6 * Ky

Explanation:

we have the following balanced reaction:

CaC2 + 2H2O = C2H2 + Ca(OH)2

the value of K for this reaction will be equal to:

K = ([C2H2] * [Ca(OH)2])/([CaC2] * [H2O]^2)

if we multiply the reaction by the value of 6, we have:

6CaC2 + 12H2O = 6C2H2 + 6Ca(OH)2

Again, the value of K for this reaction will be equal to:

K,´ = ([C2H2] ^6 * [Ca(OH)2]^6)/([CaC2]^6 * [H2O]^12) = K^6

For the second reaction:

6C2H2 + 3CO2 + 4H2O = 5CH2CHCO2H

The value of K for this reaction:

K2 = ([CH2CHCO2H]^5)/([C2H2]^6 * [CO2]^3 * [H2O]^4)

we also have:

K1 = ([CH2CHCO2H]^5)/([C2H2]^6 * [CO2]^3 * [H2O]^16)

Thus:

K1 = K^6 * Ky
