Answer:

It has 28 neutrons

Explanation:

Hi, by definition the mass number of an element if given by:

$A=n_{protons}+n_{neutrons}$

Knowing the mass number of chromiun and the amount of protons it has:

$52=24+n_{neutrons}$

$n_{neutrons}=52-24$

$n_{neutrons}=28$

It has 28 neutrons

Chromium has a total of 28 neutrons. This is found because we subtract the number of protons (the atomic number) from the mass number. 52 minus 24 gives us 28. It also has 24 electrons.

What is the limiting reactant for the following balanced equation when 9 moles of AlF3 are mixed with 12 miles of O2?

tamaranim1 [39]

<h2>Answer: $AlF_{3}$ </h2>

Explanation:

The chemical equation of the reaction that occurs when $AlF_{3}$ reacts with $O_{2}$ is

$4AlF_{3}+3O_{2}$ → $2Al_{2}O_{3}+6F_{2}$

$4$ moles of $AlF_{3}$ requires $3$ moles of $O_{2}$ .

$1$ mole of $AlF_{3}$ requires $\frac{3}{4}$ moles of $O_{2}$ .

Given that we have $9$ moles of $AlF_{3}$ .

$9$ moles of $AlF_{3}$ requires $\frac{3}{4}\times 9=6.75$ moles of $O_{2}$ .

But we have $12$ moles of $O_{2}$ .

So, $AlF_{3}$ will be consumed first.

So, $AlF_{3}$ is the limiting reagent.

What chemicals need to make liquid bakelite ?

Jet001 [13]

It begins with heating of phenol and formaldehyde in the presence of a catalyst such as hydrochloric acid, zinc chloride, or the base ammonia. This creates a liquid condensation product, referred to as Bakelite A, which is soluble in alcohol, acetone, or additional phenol.
