How many grams are equal to 0.11 mole of copper(I) chromate?

Chemistry

Evgesh-ka [11]2 years ago

8 0

Mass of Copper(I) chromate( CuCrO₄) = 19.75 g

<h3>Further explanation </h3>

The mole is the number of particles contained in a substance

1 mol = 6.02.10²³

Moles can also be determined from the amount of substance mass and its molar mass

$\tt \large{\boxed{\bold{mol=\dfrac{m(mass)}{MW(molecular~weight)}}}$

0.11 mole of Copper(I) chromate( CuCrO₄) ⇒ MW=179.54 g/mol, so mass :

$\tt mass=mol\times MW\\\\mass=0.11\times 179.54\\\\mass=19.75~g$

-. Is Electricity naturally produced in our environment.

andre [41]

Electricity is not a naturally occurring energy phenomenon like oil from the ground, but it must be created and refined at electrical power plants using other energy sources. The natural resources that create electric energy are usually non-renewable, with some exceptions.

Hope this helps

Which of the following processes absorbs energy? A) condensation of water on a wind shield of a car B) formation of copperC) bal

Alecsey [184]

Answer:

C) ball rollinflown a hill

Explanation:

The question asks to identify the endothermic process in the list of options. By way of elimination, we have;

A) condensation of water on a wind shield of a car

Condensation is an exothermic process. That is, heat is given out as the gases change into the liquid state of matter.

B) formation of copper

This is an exothermic process. Capture of electrons by a cation is always exothermic.

C) ball rollinflown a hill

This is the correct option. Energy is absorbed by the ball as it moves on the hill

D) formation of ice from liquid water

Freezing is an example of exothermic reaction. Heat is given off to the surroundings.

E) oxide from copper and oxygen

Formation of metal oxides and most reactions involving oxygen are exothermic reactions,

Stochiometry .How many grams of CO2 is produced when excess CS2 reacts with 4 mols of O2? CS2+O2-SO2 Please balance equation.

Travka [436]

Mass of CO₂ produced : 58.67 g

<h3>Further explanation</h3>

A reaction coefficient is a number in the chemical formula of a substance involved in the reaction equation. The reaction coefficient is useful for equalizing reagents and products.

Reaction

CS₂ + 3O₂ -------> CO₂ + 2SO₂

mol of CO₂ based on mol of O₂ as a limiting reactant(CS₂ as an excess reactant)

From the equation, mol ratio of mol CO₂ : mol O₂ = 1 : 3, so mol CO₂ :

$\tt \dfrac{1}{3}\times 4=\dfrac{4}{3}$

mass CO₂ (MW= 44 g/mol) :

$\tt \dfrac{4}{3}\times 44=58.67~g$
