Answer:

Si ha mirado una tabla periódica, es posible que haya notado que la masa atómica de un elemento rara vez es un número par. Dupdo

Un Dalton, también conocido como unidad de masa atómica, es aproximadamente la masa de un solo protón o neutrón. Dupdo

Es decir, el deuterio tiene el doble de masa atómica que el protio y el tritio tiene tres veces la masa atómica del protio. Dupdo

El número bariónico, que es equivalente al número de masa atómica, debe permanecer constante para que se produzca una reacción.

Can someone help please? :)

1) This is a definition.

2) Protons are given by the bottom number (since atomic number = number of protons).

3) Neutrons = (mass number)-(atomic number), which are the top and bottom numbers, respectively.

4) Nuclear fusion involves combining two things together, which is only reflected by the last option.

5) This is a fact.

6) This is a fact.

7) This is a fact.

8) This is a fact.

9) The correct option is the explanation.

The equilibrium constant is equal to 5.00 at 1300 K for the reaction:2 SO2(g) + O2(g) ⇌ 2 SO3(g). If initial concentrations are

This is an incomplete question, here is a complete question.

The equilibrium constant is equal to 5.00 at 1300 K for the reaction:

$2SO_2(g)+O_2(g)\rightarrow 2SO_3(g)$

If initial concentrations are [SO₂] = 1.20 M, [O₂] = 0.45 M, and [SO₃] = 1.80 M, the system is

A) at equilibrium.

B) not at equilibrium and will remain in an unequilibrated state.

C) not at equilibrium and will shift to the left to achieve an equilibrium state.

D) not at equilibrium and will shift to the right to achieve an equilibrium state.

Answer : The correct option is, (A) at equilibrium.

Explanation :

Reaction quotient (Q) : It is defined as the measurement of the relative amounts of products and reactants present during a reaction at a particular time.

The given balanced chemical reaction is,

$2SO_2(g)+O_2(g)\rightarrow 2SO_3(g)$

The expression for reaction quotient will be :

$Q=\frac{[SO_3]^2}{[SO_2]^2[O_2]}$

In this expression, only gaseous or aqueous states are includes and pure liquid or solid states are omitted.

Now put all the given values in this expression, we get

$Q=\frac{(1.80)^2}{(1.20)^2\times (0.45)}=5.0$

The given equilibrium constant value is, $K_c=5.00$

Equilibrium constant : It is defined as the equilibrium constant. It is defined as the ratio of concentration of products to the concentration of reactants.

There are 3 conditions:

When $Q>K_c$ that means product > reactant. So, the reaction is reactant favored.
