Grams (g) is much lighter than kilograms (kg)
You can put magnets on a fridge
Answer:
The molar heat capacity at constant volume is 21.62 JK⁻¹mol⁻¹
The molar heat capacity at constant pressure is 29.93 JK⁻¹mol⁻¹
Explanation:
We can calculate the molar heat capacity at constant pressure from

Where
is the molar heat capacity at constant pressure
is the heat capacity at constant pressure
and
is the number of moles
Also
is given by

Hence,
becomes

From the question,
= 229.0 J
= 3.00 mol
= 2.55 K
Hence,
becomes

29.93 JK⁻¹mol⁻¹
This is the molar heat capacity at constant pressure
For, the molar heat capacity at constant volume,
From the formula

Where
is the molar heat capacity at constant volume
and
is the gas constant (
= 8.314 JK⁻¹mol⁻¹)
Then,


21.62 JK⁻¹mol⁻¹
This is the molar heat capacity at constant volume
Answer:
Organic chemistry is the study of the structure, properties, composition, reactions, and preparation of carbon-containing compounds, which include not only hydrocarbons but also compounds with any number of other elements, including hydrogen, nitrogen, oxygen, halogens, phosphorus, silicon, and sulphur.
Explanation:
Answer: The correct option is 
Explanation:
Atomic mass of calcium ,Ca = 40.07 g/mol
Atomic mass of chlorine ,Cl = 35.5 g/mol
Molar mass of
:
= (Atomic mass of Ca+2 × (Atomic mass of Cl))
= (40.07 g/mol + (2 × 35.5))=111.07 g/mol

Hence, the correct option is
