Answer: See below
Explanation:
n of CO2 = 0.364mmol
Mass of C = 0.364*12 = 4.368 mg
n of H2O = 184.37 = 0.243 mol
The compound has 2*0.243mmol of H
Mass of H = 0.486 mg
Mass of O = 10.68 − (4.368+0.486) = 5.826mg
Moles of O = 0.364
<u>C:H:O Ratios</u>
0.364 : 0.486 : 0.364
= 1 : 1.34 : 1
= 3 : 4 : 3
<u>So the empirical formula is C3H4O3,</u>
Empirical formula mass
= 88= 2 × Molar mass
<u>And the molecular formula is C6H8O6</u>
Answer:
ZcH's electrons = 5-2 = +3.
ZcH for inner electrons = -5 - 0 = +5.
Explanation:
Boron 1s² 2s² 2p
As, 2s ⇒ 2.58.
2p ⇒ 2.42.
Electrons = +3.
Greater than 2 cm = 0.35
Slightly greater than +3 .
