Even though the process is endothermic, snow can sublime. The tendency in nature that accounts for this phase change is that there is a tendency toward greater entropy. The answer is number 1. The rest of the choices do not answer the question above.

<u>Answer:</u> The correct answer is Option 1.

<u>Explanation:</u>

It is given that the process is endothermic which means that \Delta H=+ve

The snow is subliming which means that it is changing its state from solid state to gaseous state directly and for this phase change to take place, \Delta G must be negative.

As, for sublimation process, \Delta S is always increasing and for spontaneous reaction, temperature must also be high.

\Delta G=\Delta H-T\Delta S

-ve=+ve-T(+ve)

At higher temperature, \Delta G will always be negative and it will be spontaneous reaction and phase change will occur.

Hence, the correct answer is Option 1.

The combustion of ethane ( C 2 H 6 ) produces carbon dioxide and steam. 2 C 2 H 6 ( g ) + 7 O 2 ( g ) ⟶ 4 CO 2 ( g ) + 6 H 2 O (
raketka [301]

Answer:

5.90 moles of ethane, C₂H₆, is burned in an excess of oxygen to produce 11.8 moles of CO₂.

Explanation:

To answer the question, we examine the chemical reaction as follows

2C₂H₆ ( g ) + 7O₂ ( g ) ⟶ 4CO₂ ( g ) + 6H₂O ( g )

From the chemical reaction it is seen that 2 moles of ethane, C₂H₆, is required to produce 4 moles of CO₂

This means that 1 mole of C₂H₆, is required to produce 2 moles of CO₂

Since we are asked to find out how many moles of CO 2 are produced when 5.90 moles of ethane is burned in an excess of oxygen and we already know that 1 mole of C₂H₆, is required to produce 2 moles of CO₂, we multiply both the 1 mole of C₂H₆ and the 2 moles of CO₂  by 5.90 to obtain;

(5.90 × 1 mole) of C₂H₆  is required to produce (5.90× 2 moles) of CO₂ or

5.90 moles of C₂H₆  is required to produce 11.8 moles of CO₂.

A 56 g sample of peanut oil has a volume of 60.9 cm³. Calculate the density of the peanut oil
aleksandr82 [10.1K]
Density = mass / volume. So you'd write it out as D = 56g / 60.9cm^3, giving you 0.9195 g/cm^3.
