1) Chemical reaction
CH3 CH2 OH + O2 ---> CH3COOH + H2O
It is balanced
2) Molar ratios
1 mol CH3 CH2OH : 1 mol O2 : 1 mol CH3COOH : 1 mol H2O
3) Conversion of 7.6 grams of ethanol to moles
Molar mass of CH3CH2OH = 2 * 12g/mol + 6 * 1 g/mol + 16 g/mol = 46 g/mol
moles = mass / molar mass = 7.6 g / 46g/mol = 0.165 mol
4) Use of proportions with the molar ratios:
1mol CH3CH2OH / 1mol O2 = 0.165 mol CH3CH2OH / x => x = 0.165 mol CH3CH2OH.
5) Conversion of 0.165 mol O2 to grams
mass in grams = number of moles * molar mass = 0.165 mol * (2 * 16g/mol)
mass = 5.28 g ≈ 5.3 g
Answer: 5.3 g
<span>The Helium gas will expand and rise into the surrounding the air as it is less dense and lighter air. Depending on the amount of helium and the size of the room the Helium could displace the breathable mix in the space and become a danger to health.</span>
Answer:
C2H6
Explanation:
Carbon forms bonds with itself, this property is called catenation and Carbon also has a tendency to form multiple bonds, double or triple. ... For C2H6, carbon forms double bond with the other carbon, and each carbon has three hydrogen atoms attached to it.
