This is an incomplete question, here is a complete question.

Determine the specific heat of a material if a 35 g sample absorbed 96 J as it was heated from 293 K to 313 K.

Answer : The specific heat of a material is, 0.137 J/g.K

Explanation :

Formula used to calculate the specific heat of a material is:

q=m\times c\times (T_2-T_1)

where,

q = heat absorbed = 96 J

m = mass of sample = 35 g

c = specific heat capacity of material = ?

T_1 = initial temperature = 293 K

T_2 = final temperature = 313 K

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

96J=35g\times c\times (313-293)K

c=0.137J/g.K

Therefore, the specific heat of a material is, 0.137 J/g.K

By the stoichiometry of this reaction if 5 mol natrium react, then 2.5 mol

natrium oxide should result.

So what have I done here? First, I had a balanced chemical equation (this is the important step; is it balanced?). Then I used the stoichiometry to get the molar quantity of product, and converted this molar quantity to mass. If this is not clear, I am willing to have another go.

Which formula shows a correct representation of the combined gas law?(1 point)
Svetlanka [38]

The formula that shows the correct representation of the combined gas law is; V1P1 / T1=V2P2 / T2

The combined gas law is obtained from the statements of Charles law and Boyle's law as follows;

Charles law; V/T = k

Boyle's law = PV = k

Combining the two I have; PV/T = k

For two masses of an ideal gas;

V1P1 / T1=V2P2 / T2

This is the statement of the combined gas law.
