Answer:

Ion

Explanation:

Ions is the charge group that includes electrons, which differentiates from the amount of protons there are in a group. (It can be more electrons or less compared to the amount of protons, but not the same).

Explanation:

Given:

Formula units of FeCl₃ = 8.65 x 10²³ formula units

Unknown:

Mass of the FeCl₃ = ?

Solution:

The formula unit is the same as the amount of subatomic particles in an atom.

1 mole of a substance = 6.02 x 10²³ formula units

For 8.65 x 10²³ formula units; the number of moles;

Number of moles = $\frac{8.65 x 10 ^{23} }{6.02 x 10^{23} }$ = 1.44moles

Now to find the mass of FeCl₃;

Mass of FeCl₃ = 1.44 x 162.2 = 233.1g

Protactinium has 516 years of half life how many decays will it go through to become 1/64th of the substance? ,

Ulleksa [173]

Answer:

6 decays

Explanation:

Each half life period reduced the amount of substance by half

64 = 2⁶
1/64 = (1/2)⁶

So 6 of half life cycles or decays will go.

For the rxn CaCo3(s)+2Hcl(aq)_CaCl(aq)+Ca2(g)+H2O(l)68.1 g solid CaCo3 is mixed with 51.6Hcl what number of grams of Co2 will be

Svetach [21]

Answer:

29.9 g of CO₂ will be produced by the reaction.

Explanation:

This is the reaction:

CaCO₃(s) + 2HCl (aq) → CaCl₂(aq) + CO₂(g) + H₂O(l)

First of all, we state the moles of each reactant:

68.1 g . 1mol/ 100.08g = 0.680 mol of carbonate

51.6 g . 1 mol/36.45g = 1.46 mol of acid.

The solid salt is the limiting reactant. Ratio is 2:1

2 moles of acid can react to 1 mol of salt

1.46 mol of acid may react with (1.46 . 1)/2 = 0.727 moles

As we only have 0.680 moles of salt, we do not have enough.

Let's work at the product side. Ratio is 1:1

1 mo of salt can produce 1 mol of gas

0.680 moles will produce 0.680 moles of gas

We convert the moles to mass → 0.680 mol . 44g / 1mol = 29.9 g of CO₂
