Consider the following mechanism for the reaction between nitric oxide and ozone:
swat32

Answer:

A .  2 O₃(g) + 2 NO   ⇒  2 O₂ (g) + 2 NO₂(g)

B . Yes

C.   O and NO₃

Explanation:

A. The overall reaction is obtained by adding the individual steps in the reaction mechanism where we will get the reactants and product and the intermediates will cancel.

Thus, adding 1+ 2 +3 we get

2 O₃(g) + 2 NO   ⇒  2 O₂ (g) + 2 NO₂(g)

B. The reaction intermediates are those that are produced from the initial and/or subsequent steps and are consumed later on in the reaction mechanism, but  are neither reactants nor products, they just participate.

From this definition it follows that O(g) and NO₃ are reaction intermediates.

C. O and NO₃

Please help!! Balancing Nuclear Equations
sineoko [7]

The missing part of the equation is found to be 4/2He. Option A

<h3>What are nuclear equations?</h3>

The term nuclear equations have to do with the type of equation in which one type of nucleus is transformed into another sometimes by the bombardment or loss of a particle.

Now the full equation ought to be written as 7/3Li + 1/1H -----> 4/2He + 4/2He. This is because the total mass on the left is 8 and the total charge on the left is 4.

What is the [H+] of a solution with a pH of 3? Use a scientific calculator.
Mariulka [41]

Answer:

1 x 10⁻³.

Explanation:

∵ pH = - log[H⁺]

3 = - log[H⁺].

log[H⁺] = -3.

∴ [H⁺] = 1 x 10⁻³.
