Answer:
Neutral ions
Explanation:
Because they have a neutral charge They can only produce neutrally.
The molecular formula of a compound having the empirical formula C9H17O is calculated as below
(C9H17O)n =847.56
{(12 x9 + 1 x17 + 1 x16)}n= 847.56
147 n = 847.56
divide bot
h side by 147
n= 6
(C9H17O)6 therefore the molecular formula = C54H102O6
Reduction I think... not entirely sure though... when a molecule loses oxygen...?
Answer:
0.665 moles of CO₂
Explanation:
The balance chemical equation for the combustion of Ethane is as follow:
2 C₂H₆ + 7 O₂ → 4 CO₂ + 6 H₂O
Step 1: <u>Calculate moles of C₂H₆ as;</u>
Moles = Mass / M.Mass
Putting values,
Moles = 10.0 g / 30.07 g/mol
Moles = 0.3325 moles
Step 2: <u>Calculate Moles of CO₂ as;</u>
According to balance chemical equation,
2 moles of C₂H₆ produced = 4 moles of CO₂
So,
0.3325 moles of C₂H₆ will produce = X moles of CO₂
Solving for X,
X = 0.3325 mol × 4 mol ÷ 2 mol
X = 0.665 moles of CO₂
Do elements in a group on the periodic table have similar chemical properties because their atoms have the same number of electrons
A. same number of outermost electrons
