One lead atom, two nitrogen atoms, four oxygen atoms.
Answer:
Yup! The answer is 50 J/g* °C
Explanation:
I also took the test but I know how to work out the problem for anyone who wants to know how to solve it.
Remember the formula q = m*C*ΔT
m = the mass in grams
C = the specific heat Capacity
ΔT = change in time
q = amount of energy
So, find out what was given and what we need to look for:
m = 40 g
C = ?
ΔT = we're heating up (the temperature increases) a chemical so it needs to be a positive number. 25 - 10 = 15 °C
q = 30000 Joules
Now, set up the equation:
q = m*C*ΔT
30000 = 40 * C * 15
Multiply 40 and 15 to get 600:
30000 = 600 * C
Divide both sides by 600 to get C by itself (plug this into your calculator):
30000/600 = 600 * C/600
You are left with 50 = C
Now, you just need to plug in the units to get B. 50 J/g* °C
I hope I helped clear up any confusion! :D

You can find the answer on google for this
I THINK it is d if it’s wrong i’m so sorry
