Answer:
A. electrons simultaneously attracted by more than one nucleus
Explanation:
- Covalent bond is the bond which is formed with the sharing of the electrons between the two atoms which are taking part in the bond. It is generally formed between the atoms with similar electronegativity values.
- It is the bond which is generally occurs within non metals as they share electrons to complete their octet.
- The difference in the electronegativity values of the atoms involving in a covalent bond must not exceed the value of 1.7 .
Thus, the electrons are attracted by the two different nucleus of the atoms that are taking part in the bonding.
<u>So, the correct answer is:- A. electrons simultaneously attracted by more than one nucleus</u>
2) carbon and hydrogen only.
Answer:
in a chemical equation if the bond is ionic its the first part that is positive and the second half of the equation is negative
Explanation:
Answer: 9.08 L
Explanation:
To calculate the moles :
According to stoichiometry :
4 moles of 
require = 3 moles of 
Thus 0.54 moles of will require=
of
Standard condition of temperature (STP) is 273 K and atmospheric pressure is 1 atm respectively.
According to the ideal gas equation:
P = Pressure of the gas = 1 atm
V= Volume of the gas = ?
T= Temperature of the gas = 273 K
R= Gas constant = 0.0821 atmL/K mol
n= moles of gas= 0.405
Thus 9.08 L of at STP would be required
Answer:
The vegetable oils are liquid at room temperature. They contain double bonds. During hydrogenation double bonds break hydrogen is introduced and form vegetable ghee.
Explanation:
Hydrogenation:
It is the chemical process in which hydrogen is introduced in unsaturated hydrocarbons in the presence of catalyst Ni.
Simple hydrogenation reaction:
H₂C = CH₂ + H₂ → CH₃-CH₃
Ni
Hydrogenation is used on industrial level in the production of vegetable ghee.
The unsaturated hydrocarbons, fatty acids undergoes hydrogenation and form ghee.
The vegetable oils are liquid at room temperature. They contain double bonds. During hydrogenation double bonds break hydrogen is introduced and form vegetable ghee.
