Weight equals mass*gravity
W = mg
Given m = 3.1 kg, g = 9.8 m/s^2
W = (3.1)(9.8)
W = 30.38
B, heat, is the correct answer. Heat is represented by a capital q in thermodynamic equations.
Answer:
when u find out pls lmk! i have the same question and I've been stuck for a while lol
Answer:

Explanation:
First of all let's define the specific molar heat capacity.
(1)
Where:
Q is the released heat by the system
n is the number of moles
ΔT is the difference of temperature of the system
Now, we can find n with the molar mass (M) the mass of the compound (m).
Using (1) we have:


I hope it helps!
It's and if, then statement!
