Answer:
32.57g
Explanation:
mass = mole x molar mass
mass of LiBr = 0.375 x 86.85
mass = 32.57g
Answer:
The final temperature is 31.95° C.
Explanation:
Given that,
Initial temperature of a sample of chloroform, 
Mass of chloroform, m = 150 g
It absorbs 1 kJ of heat, Q = 10³ J
The specific heat of chloroform, c = 00.96 J/gºC
We need to find the final temperature. The heat absorbed by an object in terms of specific heat is given by :

So, the final temperature is 31.95° C.
Explanation:
so man climate change is because of global warming and 2 natural occurring is when earth tilts off the current axis and another one is because of seasonal change
