Answer:A and B
Explanation:
A substance is said to be polar when it is having a dipole (a delocalised positive and negative charge) or it is ionic (dissociate into ions when dissolved in water)
Answer:
density = 0.822 g/mL
Explanation:
We calculate the density knowing the flowing formula:
density = mass / volume
mass = 2.98 grams
volume = 21.1 × 14.2 × 12.1 = 3625 mm³ = 3.625 cm³ = 3.625 mL
density = 2.98 / 3.625 = 0.822 g/mL

Explanation:
im sorry i just wanted the 23 points
Heat required in calories is given by product of mass in g and change in temperature in degree Celsius.
Formula is given by:
where, Q = heat required in calories
m = mass of substance in g
= change in temperature in degree Celsius
Insert the given vales of mass of water and temperature in above formula, we get:
=
=
Now,
=
Thus, heat in kilocalories =
