Answer:
Acids are water-soluble and acidic chemical compounds, often expressed as the general formula HₓA.
Answer:
Both ethanol and diethyl ether have tetrahedral geometry.
Explanation:
VSEPR Rules are
1. Identify the central atom.
2. Count its valence electrons.
3. Add one electron for each bonding atom.
4. Add or subtract electrons for charge
5. Divide the total of these by 2 to find the total.
number of electron pairs.
6. Use this number to predict the shape.

Answer:
SO2 in the atmosphere is due to burning of sulphur containing fossil fuel, S+O2→SO2 and
from smelting and roasting of sulphides.
CuFeS2+O2→Cu2O+FeO+SO2
SO2 content can be controlled by using alternate source of energy for burning, as nuclear energy , solar energy , hydroelectric energy.
Fuels containing sulphur are desulphonated before burning by FGD (fuel Gas Desulphuristion).
If H2O under high pressure is used , it will dissolve SO2 and will lower pH of the soil and thus fertillity is decreased.
Explanation:
Answer:
a) 4869 kJ will be released
b) 43.86 g of octane
Explanation:
The heat of combustion is the amount of heat released when 1 mol of a substance reacts with enough oxygen .
Since the heat of combustion is per mol of combustible substance what we are required to do in this problem is calculate number moles in the reactions although in a different manner.
a) MW C3H6O = 158 g/mol
mol C3H6O = 158 g x 1 mol/58.08 g = 2.72
-1790 kJ/ mol x 2.72 mol = 4869 kJ
b) Here we are asked the mass of octane to produce 1950 kJ of heat knowing that per mol of octane we get 5074.1 kJ, then
1 mol / 5074.1 kJ x 1950 kJ = 0.384 mol
mass C8H18 = 0.384 mol x 114.23 g/mol = 43.86 g
Answer:
<h2>0.44 </h2>
Explanation:
The pH of a solution can be found by using the formula
![pH = - log [ { H_3O}^{+}]](https://tex.z-dn.net/?f=pH%20%3D%20-%20log%20%5B%20%7B%20H_3O%7D%5E%7B%2B%7D%5D)
From the question we have
We have the final answer as
<h3>0.44</h3>
Hope this helps you
