Answer:
The answer to your question is 22.5 moles of H₂SO₄
Explanation:
Data
moles of H₂SO₄ = ?
moles of Al = 15
Balanced chemical reaction
2Al + 3H₂SO₄ ⇒ Al₂(SO₄)₃ + 3H₂
To solve this problem use proportions and cross multiplication. Use the coefficients of the balanced chemical reaction.
2 moles of Al ------------------- 3 moles of H₂SO₄
15 moles of Al ------------------ x
x = (15 x 3) / 2
x = 45/2
x = 22.5 moles of H₂SO₄
-Conclusion
22.5 moles of H₂SO₄ react completely with 15 moles of Al.
Answer:
In writing the electron configuration for nitrogen the first two electrons will go in the 1s orbital. Since 1s can only hold two electrons the next 2 electrons for N goes in the 2s orbital. The remaining three electrons will go in the 2p orbital. Therefore the N electron configuration will be 1s22s22p3.

hope you get it right:)
Answer:
The key to understanding water's chemical behavior is its molecular structure. A water molecule consists of two hydrogen atoms bonded to an oxygen atom, and its overall structure is bent. This is because the oxygen atom, in addition to forming bonds with the hydrogen atoms, also carries two pairs of unshared electrons

An alternative method by which we can overcome this global issue is by harnessing Solar energy.
Discussion:
Fossil fuels cause environmental pollution. This is because they are organic compounds and on combustion, they release air pollutants such as, Carbon monoxide.
As a panacea, the use of solar panels for harnessing Solar energy in a bid to replace energy from fossil fuels will prove to be am effective method by which we can overcome the global issue of pollution caused by burning of fossil fuels.
Solar energy is a clean source of energy as there's no release of harmful air pollutants.
