A 996.9 g sample of ethanol undergoes a temperature change of -70.98 °C while releasing 62.9 calories of heat. What is the specific heat capacity of ethanol?

Explanation:

Given that,

Mass of sample, m = 996.9 g

The change in temperature of the sample,

Heat produced, Q = 62.9  calories = 263173.6 J

The heat released by a sample due to change in temperature is given by :

Where

c is the specific heat capacity

So,

So, the specific heat of ethanol is equal to .

8

explanation:

each principal energy level above the first contains one s orbital and three p orbitals. a set of three p orbitals, called the p sublevel, can hold a maximum of six electrons. therefore, the second level can contain a maximum of eight electrons - that is, two in the s orbital and 6 in the three p orbitals.

there are no statements provided but here is why:

sulfur belongs to group 16 because it can be found in nature whether it is in a free or combined state.
