Answer:
2Al + 3CuO ⟶ Al₂O₃ + 3Cu
Explanation:
Al + CuO ⟶ Al₂O₃ + Cu
1. Put a 1 in front of the most complicated-looking formula (Al₂O₃):
Al + CuO ⟶ <u>1</u>Al₂O₃ + Cu
2. Balance Al:
We have fixed 2 Al on the right. We need 2 Al on the left. Put a 2 in front of Al.
<u>2</u>Al + CuO ⟶ <u>1</u>Al₂O₃ + Cu
3. Balance O:
We have fixed 3 O on the right. We need 3 O on the left. Put a 3 in front of CuO.
<u>2</u>Al + <u>3</u>CuO ⟶ <u>1</u>Al₂O₃ + Cu
4. Balance Cu:
We have fixed 3 Cu on the right. We need 3 Cu on the right. Put a 3 in front of Cu.
<u>2</u>Al + <u>3</u>CuO ⟶ <u>1</u>Al₂O₃ + <u>3</u>Cu
Every formula now has a coefficient. The equation should be balanced.
5. Check that atoms balance:
<u>Atom</u> <u>On the left</u> <u>On the right
</u>
Al 2 2
Cu 3 3
O 3 3
The balanced equation is
2Al + 3CuO ⟶ Al₂O₃ + 3Cu
273.15 K (0 °C, 32 °F) and an absolute pressure of 101.325 kPa (14.7 psi, 1.00 atm, 1.01325 bar).
I think it is an genetic force
Answer: explained below
Explanation:
Matter can change form through physical and chemical changes, but through any of these changes, matter is conserved. The same amount of matter exists before and after the change—none is created or destroyed.
<h3><u>Answer;</u></h3>
B. Fewer protons are pumped across the inner mitochondrial membrane when FADH2 is the electron donor than when NADH is the electron donor.
<h3><u>Explanation</u>;</h3>
- NADH and FADH2 are two important electron carriers in the cellular respiration process.
- NADH is a high-energy electron carrier that is reduced during glycolysis, pyruvate processing, and the citric acid cycle, and which carries electrons to the electron transport system.
- The electron transport chain passes electrons from NADH and FADH2 to protein complexes and mobile electron carriers.
