A binary ionic compound is known to contain a cation with 51 protons and 48 electrons. The anion contains one-third the number o
7nadin3 [17]

Answer:

SbCl_3

Explanation:

The cation contains 51 protons and 48 electrons. The electrons are only lost not protons, so the element which corresponds to atomic number 51 is the cation which is Antimony (Sb).

Also, the charge on the cation is 51 - 48 = 3

This is because neutral atom contains the same number of electrons as protons.

Given the anion has one-third protons as cation which means thta:

Number of protons in anion = \frac {51}{3}=17

This corresponds to chlorine atom. The electrons are 1 greater than protons means that it has gain 1 electron.

So,

Sb     Cl

3         1

Cross multiply the valency.

So, formula is SbCl_3

Is this equation balanced and in the lowest form? 4NH3 → 2N2 + 6H2
solong [7]

Answer:

B.) No, because the coefficients could be reduced to 2,1, and 3.

Explanation:

The equation is not in its lowest molar ratio form. In this case, all of the coefficients can be divided by 2 and still result in whole numbers.

As such, the correct balanced equation is:

2 NH₃ ----> N₂ + 3 H₂

C3H8O dissolved in water
nadya68 [22]

If C3H8O is dissolved in water, it would be expected to be a strong electrolyte.

<h3>What is a strong electrolyte?</h3>

A strong electrolyte is a solute or solution (already an electrolyte) that can completely dissociates in solution.

C3H8O is one of those compounds expected to be a strong electrolyte.

Thus, if C3H8O is dissolved in water, it would be expected to be a strong electrolyte.
