what volume (ml) of 3.0M NaOH is required to react with 0.8024-g copper ii nitrate?what mass of copper ii hydroxide will form as

Ksivusya [100]

The reaction between NaOH and Cu(NO₃)₂ is as follows

2NaOH + Cu(NO₃)₂ ---> 2NaNO₃ + Cu(OH)₂

Q1) stoichiometry of NaOH to Cu(NO₃)₂ is 2:1

this means that 2 mol of NaOH reacts with 1 mol of Cu(NO₃)₂

the mass of Cu(NO₃)₂ reacted - 0.8024 g

molar mass of Cu(NO₃)₂ is 187.56 g/mol

therefore the number of Cu(NO₃)₂ moles that have reacted

- 0.8024 g/ 187.56 g/mol = 0.00427 mol

according to the stoichiometry , number of NaOH moles - 0.00427 mol x 2

then number of NaOH moles that have reacted - 0.00855 mol

In a 3.0 M NaOH solution, 3 moles are in 1000 mL of solution

Then volume required for 0.00855 mol - 1000 x 0.00855 /3 = 2.85 mL

2.85 mL of 3.0 M NaOH is required for this reaction

Q2) Assuming that there's 100 % yield of Cu(OH)₂ , we can directly calculate the mass of Cu(OH)₂ formed from the number of moles of reactants that were used up.

Stoichiometry of Cu(NO₃)₂ to Cu(OH)₂ is 1:1

this means that 1 mole of Cu(NO₃)₂ gives a yield of 1 mole of Cu(OH)₂

the number of Cu(NO₃)₂ moles that reacted - 0.00427 mole

Therefore an equal amount of moles of Cu(OH)₂ were formed

Then amount of Cu(OH)₂ moles produced - 0.00427 mol

Mass of Cu(OH)₂ formed - 0.00427 mol x 97.56 g/mol = 0.42 g

A mass of 0.42 g of Cu(OH)₂ was formed in this reaction.

What should we do<br> with the CO2?

Trava [24]

Answer:

The carbon dioxide (CO2) emitted from power plants each year doesn't have to go into the atmosphere. Researchers are optimistic that within the next decade we will be able to affordably capture CO2 waste and convert it into useful molecules for feedstock, biofuels, pharmaceuticals, or renewable fuels.

Identify the neutralization reaction.

dusya [7]

The neutralization reaction among all the reactions would be the one between an acid and a base to produce salt and water.

<h3>What is a neutralization reaction?</h3>

It is a reaction involving an acid and a base to produce salt and water.

From the list of reactions, the only reaction that involves acid and a base with salt and water being the products is the first reaction.

Thus, the neutralization reaction is represented by the equation:

$2H_3PO_4 + 3Ba(OH)_2 --- > 6H_2O + Ba(PO_4)_2$

What can u infer about Mimas and Tethys moons

liberstina [14]

<span>Scientists with NASA's Cassini mission have spotted "Pac-Man" images on moons of Saturn, Mimas & Tethys. The image in Mimas was seen in the year 2010, while in Tethys in the year 2011. The pattern appears in thermal data taken by Cassini's infrared spectrometer, with the warmer areas making up the Pac-Man shape. </span>
