Answer

203.7g

Explanation:

Heat gained= - heat lost

From the question

Mass of water = 360g

Heat capacity of water= 4.2Jg-1

Latent heat of ice= 334Jg-1

ml= -mcθ

m×334= -(360×4.2×(0-45))

334m= 68040

m= 68040/334

=203.7g

Particles of Substance X are dispersed in water to form a colloid. Which describes the electrical charges on the particles of Su
Novay_Z [31]

The correct answer is option A.

All the particles carry the same charge, which could be either positive or negative.

All the particles of substance X will have same charge on its surface, which is balanced by the oppositely charged ions in the water.

For example, soap solution (sodium palmitate) dissociates into ions:

C₁₅H₁₁COONa --> C₁₅H₁₁COO⁻ + Na⁺

The cations (Na⁺) passes into the water while the anions (C₁₅H₁₁COO⁻) form aggregates or colloids.
