Once we run out of fuel/petroleum/oil we can use hybrid automobiles using solar power or some other type of energy likes these new hybrid cars that can run with power like a battery on a controller and recharge them.
Answer:
Group 5th A.
Explanation:
The elements of group 5th A shows the electronic configuration of s² p³.
This group consist of nitrogen, phosphorus, arsenic, antimony, bismuth.
Electronic configuration of nitrogen:
N₇ = [He] 2s² 2p³
Electronic configuration of phosphorus
P₁₅ = [Ne] 3s² 3p³
Electronic configuration of arsenic
As₃₃ = [Ar] 3d¹⁰ 4s² 4p³
Electronic configuration of antimony
Sb₅₁ = [Kr] 4d¹⁰ 5s² 5p³
Electronic configuration of bismuth
Bi₈₃ = [Xe] 4f¹⁴ 5d¹⁰ 6s² 6p³
610grams that is the maxium because if you do 100+500+10 which is 610
Answer:
975.56×10²³ molecules
Explanation:
Given data:
Number of molecules of C₂H₆ = 4.88×10²⁵
Number of molecules of CO₂ produced = ?
Solution:
Chemical equation:
2C₂H₆ + 7O₂ → 4CO₂ + 6H₂O
Number of moles of C₂H₆:
1 mole = 6.022×10²³ molecules
4.88×10²⁵ molecules×1mol/6.022×10²³ molecules
0.81×10² mol
81 mol
Now we will compare the moles of C₂H₆ with CO₂.
C₂H₆ : CO₂
2 : 4
81 : 4/2×81 = 162 mol
Number of molecules of CO₂:
1 mole = 6.022×10²³ molecules
162 mol ×6.022×10²³ molecules / 1 mol
975.56×10²³ molecules
