H has a charge of +1, and O has a charge of -2. In this case, C in C7H12 would have a charge of -12/7 to balance it out. Meanwhile, C in CO2 would have a charge of +4. Since the charge of C went from negative to positive, this implies that C lost electrons, which is indicative of oxidation (and thus it was the reducing agent). Therefore, C7H12 was the reducing agent, while O2 was the oxidizing agent.

D. a program on a computer
Explanation:
Answer:
4NH₃ + 5O₂ → 4NO + 6H₂O ΔH = -904 kj
Explanation:
Given data:
Energy evolved when one mole of NH₃ react = 226 kj
Energy evolved when 4 mole of NH₃ react = ?
Solution:
Chemical equation:
4NH₃ + 5O₂ → 4NO + 6H₂O
It is stated in question that when one mole of ammonia react 226 kj energy evolved.
When 4 moles react energy evolved is,
1 mol = -226 kj
4 mol × -226 kj / 1mol
-904 kj
when 4 moles of ammonia react 904 kj energy is evolved.
Complete thermal equation:
4NH₃ + 5O₂ → 4NO + 6H₂O ΔH = -904 kj
Answer:
A. Antoine Lavoisier
Explanation:
He is know for creating the first chemical textbook. This textbook included rules for naming different chemical compounds, which is the still the same method we use to this day.
Hoped this can help! :D
Answer:
0.20 moles
Explanation:
In order to solve this problem it is necessary to keep in mind the definition of molarity:
- Molarity = moles / liters
If we<u> input the data given by the problem</u> we're left with:
Meaning that we can proceed to <u>calculate the number of moles</u>:
