Answer:

this is what i got

Explanation:

α-decay: When a radioactive nucleus disintegrates by emitting an αα-particle, the atomic number decreases by two and mass number decreases by four. Example: 88Ra226→86Rn222+2He4.

The molar heat capacity of a compound with the formula C2H6SO is 88.0 J/mol-K. The specific heat of this substance is __________

lisabon 2012 [21]

Answer : The specific heat of this substance is, 1.13 J/g.K

Explanation :

Molar heat capacity : It is defined as the amount of heat absorbed by one mole of a substance to raise its temperature by one degree Celsius.

As we are given that the chemical formula of compound is, $C_2H_6SO$

First we have to calculate the molar mass of given compound.

Molar mass of $C_2H_6SO$ = $2(12g/mol)+6(1g/mol)+32g/mol+16g/mol$

Molar mass of $C_2H_6SO$ = 78 g/mol

Now we have to calculate the specific heat of this substance.

Specific heat of this substance = $\frac{\text{Molar heat capacity of a compound}}{\text{Molar mass of }C_2H_6SO}$

Specific heat of this substance = $\frac{88.0J/mol.K}{78g/mol}$

Specific heat of this substance = 1.13 J/g.K

Thus, the specific heat of this substance is, 1.13 J/g.K

Which element is closely associated with the field of organic chemistry?

slega [8]

Answer:

Carbon

Explanation:

The field of organic chemistry is the field of the study of the compounds of carbon mostly with hydrogen but they can contain the presence of other atoms such as oxygen, nitrogen, sulfur even metals such as lithium. It studies the structure, properties, synthesis and reactions of these compounds. The field of organic chemistry is the field of living organisms as they are mostly are formed by organic compounds hence its name organic.
