Answer: 3.6%
5.5 - 5.3 and divide it by 5.5. Then multiply this by 100
Explanation:
This will get you 3.6%
<span>energy provided=13.4 eV
energy released=0.7 eV
energy absorbed = 12.7eV
initial energy= -13.6eV [ground state]
final energy = -13.6+12.7 = -0.9 eV
This energy corresponds to n=4 in hydrogen atom</span>

Answer:
0.60 mol
Explanation:
There is some info missing. I think this is the original question.
<em>Acetylene gas is often used in welding torches because of the very high heat produced when it reacts with oxygen gas, producing carbon dioxide gas and water vapor. Calculate the moles of oxygen needed to produce 1.5 mol of water.</em>
<em />
Step 1: Given data
Moles of water required: 1.5 mol
Step 2: Write the balanced equation
C₂H₂(g) + 2.5 O₂(g) ⇒ 2 CO₂(g) + H₂O(g)
Step 3: Calculate the moles of oxygen needed to produce 1.5 mol of water
The molar ratio of O₂ to H₂O is 2.5:1. The moles of oxygen needed to produce 1.5 mol of water are (1/2.5) × 1.5 mol = 0.60 mol
Answer:The trans isomer of the Alkene
Explanation: Alkene have the ability to form geometric isomers when the Hydrogen are at the opposite direction of the carbon it leads to a Trans Alkene but when they are at the adjacent it is called a Cis Alkene
