Yes. Racist it will make it harder to move almost like ooblek
For Iron:

For Oxygen:

These are the two chemical symbols for the two elements found in Iron Oxide.
In No3-1 the oxidation number of oxygen is -5 so oxidation number of N would be +5
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.
