# What is the mole ratio of pcl3 to pcl5?

Contents

Answer : The mole ratio of to is 1 : 1 ratio.

## What is the mole to mole ratio of cl2 to PCl3?

Chlorine and phosphorus trichloride have a 3:2 mole ratio, which means that the reaction will always need 3/2 times more moles of chlorine gas than the number of moles of phosphorus trichloride produced.

## What is the mole ratio for O2 to SO3?

One mole of O2 will produce two moles of SO3 , so the mole ratio is 1:2.

## Where do mole ratio numbers come from?

A mole ratio is a conversion factor that relates the amounts in moles of any two substances in a chemical reaction. The numbers in a conversion factor come from the coefficients of the balanced chemical equation.

## What is the mole ratio of NaOH to Al OH 3?

The molar ratios of NaOH to Al(OH)3 are 3 to 1. Therefore, 2.3 moles of NaOH would produce (1/3)*(2.3) moles of Al(OH)3.

## Do you reduce mole ratios?

The molar ratio can be constructed using any two compounds in the reaction, be they reactants or products. Write the molar ratios for (a) O2 to SO3 and (b) SO2 to SO3. … Note that both ratios can be reduced.

## What is the relationship between a mole and Avogadro’s number?

One mole of a substance is equal to 6.022 × 10²³ units of that substance (such as atoms, molecules, or ions). The number 6.022 × 10²³ is known as Avogadro’s number or Avogadro’s constant. The concept of the mole can be used to convert between mass and number of particles.. Created by Sal Khan.

## Which must be the same when comparing 1 mol?

Explanation : When comparing 1 mol of oxygen gas with 1 mol of carbon monoxide the number of molecules must be same. Each mole should contains in it. Irrespective of the weight or atomic number avogadro’s number remains constant for every mole of atom.

## What is the mole ratio of zinc to zinc sulfate?

Answer: The mole ratio of zinc to zinc sulfate is 1:1.

## How many moles of O2 are needed to 4 moles of SO3?

every mole of SO2 requires 1 extra mole of O (or half a mole of O2) to produce SO3 and and since there are 4 moles of SO2 then you’ll need 4 moles of O (2 moles of O2) thus the answer should be 2 moles of oxygen are required.

## What is the limiting reagent when 3.1 mol of SO2?

Answer: According to the reaction equation, 2 moles of SO2 fully react with 1 mole of O2, theoretical molar ratio is 2:1. And the real molar ratio is: n(SO2)/n(O2) = 3.1/2.7 = 1.15:1. As you can see, SO2 is in deficit in comparison to the theoretical ratio. It means, that SO2 is the limiting reagent.

## What is the mole ratio of Fe3O4?

What is the mole ratio of Fe3O4 to Fe? A- 1:3.

## What is the mole ratio of HCL to zncl2?

At the same time, you have a 2:1 mole ratio between hydrochloric acid and hydrogen gas. This means that the reaction will always produce half as many moles of hydrogen gas as you have moles of hydrochloric acid.

## Are mole ratios always whole numbers?

The mole ratio did not turn out to be whole numbers. Since the we cannot have partial atoms in the empirical formula, a multiplication factor must be applied to get whole numbers.
