Answer:
Explanation:
7.706 g of CO₂ will contain 12 x 7.706 / 44 g of C
= 2.1 g of C .
This will be contained in 3.256 g of isopentyl acetate
3.156 g of H₂O will contain 2 x 3.156 / 18 g of H
= .351 g of H
This will be contained in 3.256 g of isopentyl acetate
Rest will be oxygen
amount of oxygen in 3.256 g of isopentyl acetate
= 3.256 - ( 2.1 + .351 )
= .805 g
ratio of C , H , O in isopentyl acetate
= 2.1 g : .351 g : .805 g
2.1 / 12 : .351 / 1 : 0.805 / 16 ratio of moles
= .175 : .351 : .05 ratio of moles
= 3.5 : 7.02: 1
= 7 : 14 : 2
empirical formula of isopentyl acetate
= C₇ H₁₄ O₂ .

CF4 is the compound that has polar bonds, but dipole moment of O. C-f bond is a polar bond which is covalent. It has dipole of 4 polar C.F bonds and results in the overall monopolar molecule.
CF4 it has no net dipole moment.
Answer:
Rewrite the following sentence in reported speech
The chair person said,"A hearty welcome to all present!"
Hey there!
Given the reaction:
4 AI + 3O2 ------> 2 AI2O3
4 moles Al --------- 3 moles O2
9.30 moles Al --------- ?? moles O2
9.30 * 3 / 4 => 6.975 moles of O2
Molar mass O2 => 32.0 g
Therefore:
6.975 * 32.0 => 223.3 g of Oxygen
Hope that helps!
