Answer :By the time thermal equilibrium is attained in the system, ice is completely converted to water.
What is tehrmal equilibrium?
Thermal equilibrium is a situation in which two substances are exactly at the same temperature. That is. Heat is no longer flowing beween the bodies.
Recall that an insulated thermos flask implies that heat does not eneter or leave the system. Heat will flow from the water to the ice untill the both attains the same temperature and the ice is completely converted to water.
Have a good day
Your answer is correct.
2NaCl(s) ---T--> 2Na(s) + Cl2(g)

B, they taste Bitter. Hope this helps. If i'm wrong please let me know.
Given , Speed of light = 3 × 10⁸ m/s
Distance = 40 × 1.61× 1000 m
= 264400 m
We know that, speed = distance/time
so, time = distance/speed
t = 264400 / 3 × 10⁸
t = 0.00881333 sec Approx
The answer is 0.00881333 sec Approx
I guess it is A and i think i m correct
