bija089 [108]

Answer:

Option A, C, D

Explanation:

A reversible adiabatic process is an isentropic process as entropy remains constant. Thus,

Entropy change (Delta S) = integral of (Q_rev)/T

Thus, option A and C are correct

For a reversible process, entropy generation is a positive quantity or zero. hence, statement B is not true

In an Adiabatic processes, entropy do not decrease. Hence, option D is also correct

In a certain chemical reaction, 2 solid Mg atoms bond with O2 gas to produce solid
soldier1979 [14.2K]

Answer:

Option B. 2Mg(s) + O2 (g) —> 2MgO (s)

Explanation:

From the question given above,

We were told that:

2 solid Mg atoms bond with O2 gas to produce solid MgO.

This can be represented by an equation as follow:

2Mg(s) + O2 (g) —> MgO (s)

Next, we shall balance the above equation as follow:

2Mg(s) + O2 (g) —> MgO (s)

There are 2 atoms of Mg on the left side and 1 atom on the right side. It can be balance by putting 2 in front of MgO as shown below:

2Mg(s) + O2 (g) —> 2MgO (s)

Now, the equation is balanced.

How many grams are in 2.54 x 10^23 molecules of CO2
Ivan

Answer:

=<em><u> 0.42 moles of CO2 </u></em>

Explanation:

From Avogadro's constant

6.02×10^23 molecules are in 1 mole of CO2

2.54×10^23 molecules will be in

=[(2.54×10^23) ÷ (6.02×10^23)]

= 0.42 moles of CO2
