Answer: The chemical formula of the given compound is $Cr_2(SO_4)_3$

Explanation:

The combination of chromium and sulfate ions leads to the formation of an ionic compound having chemical name as chromium (III) sulfate. The electrons get transferred from chromium atom to sulfate ion.

Chromium is the 24th element of the periodic table. It is a metal and it looses its electrons. The electronic configuration for this element is $1s^22s^22p^63s^23p^64s^23d^{4}$

This element will loose 3 electrons and forms $Cr^{3+}$ ion.

Sulfate ion is a polyatomic ion having chemical formula of $SO_4^{2-}$

By criss-cross method, the oxidation state of the ions gets exchanged and they form the subscripts of the other ions. This results in the formation of a neutral compound.

So, the chemical formula for chromium (III) sulfate is $Cr_2(SO_4)_3$

With 21 g of Zinc, and 7 g of CuCl2, how much ZnCl2 is made in grams?

mina [271]

Answer: 7.07 grams

Explanation:

To calculate the moles :

$\text{Moles of solute}=\frac{\text{given mass}}\times{\text{Molar Mass}}$

$\text{Moles of} zinc=\frac{21g}{65g/mol}=0.32moles$

$\text{Moles of} CuCl_2=\frac{7g}{134g/mol}=0.052moles$

$Zn+CuCl_2\rightarrow Cu+ZnCl_2$

According to stoichiometry :

1 mole of $CuCl_2$ require 1 mole of $Zn$

Thus 0.052 moles of $CuCl_2$ will require= $\frac{1}{1}\times 0.052=0.052moles$ of $Zn$

Thus $CuCl_2$ is the limiting reagent as it limits the formation of product and $Zn$ is the excess reagent.

As 1 mole of $CuCl_2$ give = 1 mole of $ZnCl_2$

Thus 0.052 moles of $CuCl_2$ give = $\frac{1}{1}\times 0.052=0.052moles$ of $ZnCl_2$

Mass of $ZnCl_2=moles\times {\text {Molar mass}}=0.052moles\times 136g/mol=7.07g$

Thus 7.07 g of $ZnCl_2$ will be produced from the given masses of both reactants.

4NH3 + 3O2 mc004-1.jpg 2N2 + 6H2O

ioda

Assuming the complete question is;
Consider the balanced equation below;
4NH3 + 3O2 = 2N2 +6H2O
What is the mole ratio of NH3 to N2;
From the balanced equation; the mole ratio of NH3 to N2 is 4:2.
The mole ratio is the ratio of moles of one substance to the number of moles of another substance in a balanced equation. In the above equation; 4 moles of ammonia requires 3 moles of oxygen to produce two moles of nitrogen and six moles of water.
