Answer:
(a) The lewis structure for methylisocyanate is in the attached.
(b) The carbonyl carbon have an sp² hybridization
(c) The nitrogen have an sp² hybridization?
Explanation:
(a) The lewis structure for methylisocyanate has the nitrogen with one lone pair and the oxygen with two lone pairs.
(b) The carbonyl carbon form double bond with the oxygen causing to form three hybrid orbitals sp².
The Nitrogen also forms a double bond with the carbon having an sp² hybridization too.
Answer:
Explanation:
Moles of NaCl :
Given, Mass of NaCl = 72.24 g
Molar mass of NaCl = 58.44 g/mol
The formula for the calculation of moles is shown below:
Thus,
NaCl is a strong salt. So, moles of chloride ion = 1.2361 moles
Volume = 0.862 L
15 protons (atomic number is always the number of protons) 15 electrons because no charge was mentioned so it must be the same as protons 16 neutrons because mass number is the combined number of protons and neutrons
Answer:
The answer to your question is 1795.5 grams of CO₂
Explanation:
Data
mass of carbon dioxide = ?
mass of Octane = 571.3 g
Process
1.- Write the balanced chemical reaction
C₈H₁₆ + 12O₂ ⇒ 8CO₂ + 8H₂O
2.- Calculate the molar mass of octane and carbon dioxide
Octane = (12 x 8) + (16 x 1) =96 + 16 = 112 g
Carbon dioxide = 8[ 12 + 2(16)] = 352 g
3.- Use proportions to find the mass of carbon dioxide
112 g of Octane ---------------- 352 g of carbon dioxide
571.3 g of Octane ------------- x
x = (571.3 x 352) / 112
x = 201097.6 / 112
x = 1795.5 grams of CO₂
