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

2. A 2.75 kg sample of a substance occupies a volume of 250.0 cm^3. Find its density in g/cm.
hichkok12 [17]

Answer:

<h3>The answer is 11 g/cm³</h3>

Explanation:

The density of a substance can be found by using the formula

density =  \frac{mass}{volume}  \\

From the question

mass = 2.75 kg = 2750 g

volume = 250 cm³

We have

density =   \frac{2750}{250}  \\

We have the final answer as

<h3>11 g/cm³</h3>

Hope this helps you

If a temperature increase from 18.0 ∘C to 37.0 ∘C triples the rate constant for a reaction, what is the value of the activation
iragen [17]

Answer : The activation energy for the reaction is, 43.4 KJ

Explanation :

According to the Arrhenius equation,

K=A\times e^{\frac{-Ea}{RT}}

or,

\log (\frac{K_2}{K_1})=\frac{Ea}{2.303\times R}[\frac{1}{T_1}-\frac{1}{T_2}]

where,

K_1 = rate constant at 18.0^oC

K_2 = rate constant at 37.0^oC = 3K_1

Ea = activation energy for the reaction = ?

R = gas constant = 8.314 J/mole.K

T_1 = initial temperature = 18.0^oC=273+18.0=291K

T_2 = final temperature = 37.0^oC=273+37.0=310K

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

\log (\frac{3K_1}{K_1})=\frac{Ea}{2.303\times 8.314J/mole.K}[\frac{1}{291K}-\frac{1}{310K}]

Ea=43374.66J/mole=43.4KJ

Therefore, the activation energy for the reaction is, 43.4 KJ
