Which compound is an electrolyte? 1. H2O 2. C2H6 3. H3PO4 4. CH3OH

Answers

An electrolyte is a substance that releases ions when it is dissolved in water. Electrolytes are divided into salts, ions and bases. In this case, the electrolyte is H₃PO₄ as it releases H+ ions and PO₄⁻³ ions when it is dissolved in water.

The electrolyte is H₃PO₄, this is because it releases H⁺ ions and PO₄⁻³ ions when it is dissolved in water

What is an electrolyte?

In chemistry, an electrolyte is a substance that has the capacity of conducting electric current by dissociating into positively and negatively charged ions, which migrate to the cathode and anode of an electric circuit, respectively.

  • Electrolyte releases ions when it is dissolved in water.

From the given information;

The electrolyte is H₃PO₄, this is because it releases H⁺ ions and PO₄⁻³ ions when it is dissolved in water.

Molar mass CO2 is 44.01 g/mol. How many moles of LiOH are needed to react completely with 25.5 g of CO2?

Answers

Given:

Molar mass CO2 is 44.01 g/mol

25.5 g of CO2

 

Required:

Moles of LiOH

 

Solution:

Balanced equation is:

2LiOH +CO2 → Li2CO3 + H2O

 

25.5g CO2 (1 mole CO2/44.01 g/mol CO2)(2 moles LiOH/1 mol CO2) = 1.16 moles LiOH

Molarmass carbon dioxide is 44.01 g/mol, 1.16 moles of LiOH are needed to react completely with 25.5 g of CO₂.

Stoichiometry and the molar ratios of CO₂ and LiOH must be used to calculate the number of moles of LiOH required to totally react with 25.5 g of CO₂.

The reaction between CO₂ and LiOH has the following chemical formula:

CO₂ + 2LiOH -> Li₂CO₃ + H₂O

Now,

Molar mass of CO₂ = 44.01 g/mol

Mass of CO₂ = 25.5 g

Number of moles of CO₂ = Mass of CO2 / Molar mass of CO2

= 25.5 g / 44.01 g/mol

≈ 0.58 moles of CO2

As per this,

Number of moles of LiOH = 2 * Number of moles of CO2

= 2 * 0.58 moles

= 1.16 moles of LiOH

Thus, 1.16 moles of LiOH are needed for the given reaction.

How many moles of H2 are needed to react with 1 mole off N2?

Answers

3 H + N = 2 NH

3 moles H₂ ------- 1 mole N₂
? moles H₂ -------- 1 mole N₂

H₂ = 1 * 3 / 1

H₂ = 3 / 1

= 3 moles of H₂
