Aqueous hydrochloric acid HCl will react with solid sodium hydroxide NaOH to produce aqueous sodium chloride NaCl and liquid wat

Mashcka [7]

Answer:

0.26g of NaCl is the maximum mass that could be produced

Explanation:

Based on the reaction:

HCl + NaOH → NaCl + H₂O

Where 1 mol of HCl reacts per mol of NaOH to produce 1 mol of NaCl

To solve this question we need to find limiting reactant. The moles of limiting reactant = Moles of NaCl produced:

Moles HCl -Molar mass: 36.46g/mol-:

0.365g HCl * (1mol / 36.46g) = 0.010 moles HCl

Moles NaOH -Molar mass: 40g/mol-:

0.18g NaOH * (1mol / 40g) = 0.0045 moles NaOH

As the reaction is 1:1 and moles NaOH < moles HCl, limiting reactant is NaOH and maximum moles produced of NaCl are 0.0045 moles.

The mass of NaCl is:

Mass NaCl -Molar mass: 58.44g/mol-:

0.0045 moles * (58.44g/mol) =

<h3>0.26g of NaCl is the maximum mass that could be produced</h3>

Which set of chemical name and chemical formula for the same compound is correct?A. Ammonium sulfite, (NH4)2SB. Iron(III) Phosph

gregori [183]

Answer : The correct option is, Iron(III) phosphate, $FePO_4$ .

Explanation :

Ionic compound : It is defined as the compound which is formed when electron gets transferred from one atom to another atom.

All the polyatomic ions always form an ionic compound.

Polyatomic ions : It is a charged species that composed of two or more atoms and these charged species are bonded by the covalent bond.

(1) The chemical formula for Ammonium sulfite.

The given compound ammonium sulfate is an ionic compound. It is made up of two different ions which are ammonium ion $(NH_4^+)$ and sulfite ion $(SO_3^{2-})$ by the criss-cross method. Thus, the correct chemical formula for ammonium sulfite is $(NH_4)_2SO_3$ .

(2) The chemical formula for Iron(III) phosphate.

The given compound iron(III) phosphate is an ionic compound. It is made up of two different ions which are iron ion $(Fe^{3+})$ and phosphate ion $(PO_4^{3-})$ by the criss-cross method. Thus, the correct chemical formula for iron(III) phosphate is $FePO_4$ .

(3) The chemical formula for Lithium carbonate.

The given compound lithium carbonate is an ionic compound. It is made up of two different ions which are lithium ion $(Li^+)$ and carbonate ion $(CO_3^{2-})$ by the criss-cross method. Thus, the correct chemical formula for lithium carbonate is $Li_2CO_3$ .

(4) The chemical formula for Magnesium dichromate.

The given compound magnesium dichromate is an ionic compound. It is made up of two different ions which are magnesium ion $(Mg^{2+})$ and dichromate ion $(Cr_2O_7^{2-})$ by the criss-cross method. Thus, the correct chemical formula for magnesium dichromate is $MgCr_2O_7$ .

From this we conclude that, the correct set of chemical name and chemical formula for the same compound is Iron(III) phosphate.

Hence, the correct option is, Iron(III) phosphate, $FePO_4$ .
