Lead has an atomic number of 82. Which statement describes all neutral atoms and ions of lead?
IRINA_888 [86]

The neutral atom of lead must have 82 protons while ions can have b or less than 82.

The atomic number of an element is the number of protons in the nucleus of the element.

Also, for neutral atoms, the number of protons equals the number of electrons.

In ionic form, the number of protons/electrons of an atom may vary and be different from that of the neutral form.

Positive charges mean that the ion has less proton than its neutral version while negative charges mean that it has more electrons than its neutral version.

Thus, the neutral atom of lead will contain an equal number of protons as the electrons while its ionic form can have more or less than 82 protons.

For the reaction COCl2(g)⇌CO(g)+Cl2(g), K= 2.19×10−10 at 373 K
vladimir1956 [14]

Answer:

D) The equilibrium lies far to the left

Explanation:

According to the law of mass action, the equilibrium constant K for the reaction at 373K can be calculated as follows:

K = \frac{[CO][Cl_{2}]}{[COCl_{2}]} = 2.19×10^{-10}

([X] means = concentration of X)

This means that in the equilibrium the concentration of the reactant (that is in the denominator) will be much higher (around 10^{10} fold) than the concentrations of the products (that are in the numerator), and this means that the equilibrium lies far to the left (to the reactants side) as very small amount of product is being formed.
