The mass of carbon required to produce iron from 5 67 g iron (iii) oxide is 9.0 g.

<h3>What is the mass of carbon required to produce iron from iron (iii) oxide?</h3>

The mass of carbon required to produce iron from iron (iii) oxide is determined from the equation of the reaction.

From the given equation of reaction, 3 moles of carbon produces 4 moles of iron.

  • Moles of a substance = mass/molar mass

Molar mass of iron = 56.0 g

molar mass of carbon = 12.0 g

Moles of iron in 5.67 g of iron = 5.67/56 = 0.1 moles

Moles of carbon required = 3/4 × 0.1 = 0.75 moles

Mass of carbon = 0.75 × 12 = 9.0 g

Therefore, the mass of carbon required to produce iron from 5 67 g iron (iii) oxide is 9.0 g.

What is evaporation? Describe what happens at the molecular level during evaporation.

 Evaporation happens<span> when atoms or </span>molecules<span> escape from the liquid and turn into a vapor.

How many grams of lithium hypochlorite (LiClO) are there in 0.594 moles?
Flauer [41]

Answer : The mass of lithium hypochlorite are, 34.7 grams.

Explanation : Given,

Moles of LiClO = 0.594 g

Molar mass of LiClO = 58.4 g/mol

Expression used :

\text{ Mass of }LiClO=\text{ Moles of }LiClO\times \text{ Molar mass of }LiClO

Now put all the given values in this expression, we get:

\text{ Mass of }LiClO=(0.594moles)\times (58.4g/mole)

\text{ Mass of }LiClO=34.7g

Therefore, the mass of lithium hypochlorite are, 34.7 grams.

Which substance is a base? HCOOH RbOH H2CO3 NaNO3
Alex Ar [27]

Answer:

RbOH

Explanation:

For this question, we have to remember what is the definition of a base. A base is a compound that has the <u>ability to produce hydroxyl ions</u> OH^-, so:

AOH~->~A^+~+~OH^-

With this in mind we can write the <u>reaction for each substance:</u>

HCOOH~->~HCOO^-~+~H^+

RbOH~->~Rb^+~+~OH^-

H_2CO_3~->~CO_3^-^2~+~2H^+

NaNO_3~->~Na^+~+~NO_3^-

The only compound that fits with the definition is RbOH, so this is our <u>base</u>.

I hope it helps!
