Answer:
             1.8 mol of CuO

Solution:

The balanced chemical equation is as follow,

                               2 Cu₂O  +  O₂     →     4 CuO

According to equation,

                     2 moles of Cu₂O produced  =  4 moles of CuO
So,
          0.900 moles of Cu₂O will produce  =  X moles of CuO

Solving for X,
                     X  =  (0.900 mol × 4 mol) ÷ 2 mol

                     X  =  1.8 mol of CuO

What happens to the atomic radius of elements as you move from left to right across a period?​
Katyanochek1 [597]

Explanation:

Moving from left to right across a period, the atomic radius decreases. The nucleus of the atom gains protons moving from left to right, increasing the positive charge of the nucleus and increasing the attractive force of the nucleus upon the electrons.

Janice is given a mixture of alcohol and water. The teacher tells her that she can use temperature to separate these compounds.
Rina8888 [55]
Hello!

The property that is being demonstrated when Janice was given a mixture of alcohol and water and her teacher told her that she could use temperature to separate these compounds is boiling.

The boiling point is the temperature when a substance goes from liquid state to gas state. If two liquid substances with different boiling points are in a mixture, they can be separated by heating one of them to its boiling point and condensing the gas in another container in a process called distillation. The difference in boiling points of alcohols (usually lower than water) and water allows to separate them in a mixture.

Have a nice day!

VLD [36.1K]

Answer:

17.86mL of the HCl solution

Explanation:

The reaction of CaCO₃ with HCl is:

CaCO₃ + 2HCl → CaCl₂ + CO₂ + H₂O

The concentration of HCl with a pH of 1.52 is:

pH = 1.52 = -log [H⁺]

[H⁺] = 0.0302M = [HCl]

27.0mg = 0.0270g of CaCO₃ (Molar mass: 100.09g/mol) are:

0.0270g of CaCO₃ ₓ (1mol / 100.09g) = <em>2.70x10⁻⁴ moles of CaCO₃</em>

Moles of HCl to react completely with these moles of CaCO₃ are:

2.70x10⁻⁴ moles of CaCO₃ ₓ (2 mol HCl / 1 mol CaCO₃) =

5.40x10⁻⁴ moles of HCl

As the concentration of HCl is 0.0302M, volume in 5.40x10⁻⁴ moles is:

5.40x10⁻⁴ moles of HCl * (1L / 0.0302mol) = 0.01786L =

<h3>17.86mL of the HCl solution</h3>
