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

Numbers above zero are significant, as well as any zeros that appear in between two non-zero numbers.
For for the formulas with the abbreviated names of the ions, you switch the exponents for each one, so for number 2 it would be Fe2O3 or for 6 it would be CaCl2
For the compounds, you take the abbreviated names of the ions from the periodic table and wherever the ion falls, that’s how many electrons it has and so it would need more ions to make the full shell, so for sodium chloride, since both need one, it would be NaCl or for tin (ll) fluoride, it would be SnF2
Answer:
H₂O Gained Electron.
H₂O is <span>Bronsted-Lowry Base.
Explanation:
Due to amphoteric nature of water it can act as acid when reacted with strong base, also it can act as base when reacted with strong acid.
In given statement water is treated with strong acid hence it is acting as Bronsted-Lowery Base, as it accepting H</span>⁺. So those species which accepts proton are called as Bronsted-Lowry Base and those which donated proton are called as <span>Bronsted-Lowry Acid.

H₂O + H⁺ → H₃O⁺
