A molecule of an organic compound contains at least one atom of
2 answers:
Answer: (1) carbon
Explanation: Organic compounds are those compounds which contains a carbon atom. Nearly all organic compounds contain hydrogen and some of the organic compounds contain oxygen. Example: Glucose(), Methane (
)
Inorganic compounds are those compounds which do not contain a carbon atom. Example :

Answer:
63.52°C is the final temperature
Explanation:
1) 131.0 mL of water at 26.0°C
Mass of water = m
Volume of the water =131.0 mL
Density of the water = 1.00 g/mL
m = 131.0 g
Initial temperature of the water = = 26.0°C
Final temperature of the water =
Change in temperature ,
Heat absorbed 131.0 g of water = Q
2) 81.0 mL of water at 85.0°C
Mass of water = m'
Volume of the water =81.0 mL
Density of the water = 1.00 g/mL
m' = 81.0 g
Initial temperature of the water = = 85.0°C
Final temperature of the water =
Change in temperature ,
Heat lost by 81.0 g of water = Q'
After mixing both liquids the final temperature will become equal fro both liquids.
Since, heat lost by the water at higher temperature will be equal to heat absorbed by the water at lower temperature.
Q=-Q' (Law of conservation of energy.)
Let the specific heat of water be c
63.52°C is the final temperature
Answer: will make an electrolytic solution
Explanation:
Electrolyte is a substance which dissociates into ions when dissolved in water and thus is able to conduct electric current through them.
Compounds in solid form does not conduct electricity due to the absence of free ions.
a) is a covalent compound and thus not an electrolyte.
b) is a covalent compound and thus do not dissolve in water and thus is not an electrolyte.
c) is an ionic compound and thus dissolve in water and give ions which help to conduct electricity.
d) is a covalent compound and thus do not dissolve in water and thus is not an electrolyte.
