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

A fusion reaction takes place between carbon and another element. Neutrons are released, and a different element is formed. The

sdas [7]

Answer:

Dependent on the element that reacted with carbon

Explanation:

Nuclear fusion is the combination of small atomic nuclei into larger ones usually accompanied with the release of a large amount of energy.

From the problem stated, carbon fuses with another atom. The combined atom would have more nuclear particles in terms of protons and neutrons than the combining atoms. This will eventually make it weigh more than carbon and the atom it combines with. The resulting weight will depend on the combining atoms eventually.
