Answer:
A,D,E,F
Explanation:
A.Ketones generally have lower boiling points in relation to alcohols because of the intermolecular hydrogen bonds.
D.Aldehyde group is known for this C=O group in which Carbon has a double bond with Oxygen.
E. Aldehydes and Ketones can’t hydrogen bond with each other but they can hydrogen bond with water
F. Formaldehyde used in the laboratory for preservation is a liquid at room temperature while propanol which has more carbon is gaseous
B is wrong because as the Carbon increases the solubility in water decreases
C is wrong because 2-butanol has a bp of 100 degree celsius while butanal has a bp of around 74.
Answer:
None of the conditions will favor either the forward reaction or backward reaction , hence the answer is D
Explanation:
- The principle of chemical Equilibrium is applied here, where the concentration of the reactants or the forward reaction is same as the concentration of the products or the backward reaction.
- The equilibrium constants is also involved here, K can be in terms of pressure (Kp) or concentration (Kc) hence equilibrium constant is the ration of the concentration of the products to the concentration of the reactants raised to the power of the coefficient of the reactants and products.
- Partial pressure , total pressure and the mole fraction relationship is also applied
- The step by step explanation is as shown in the attachment below.
Answer:
Both animal and plant cells are eukaryotic cells and have several similarities. The similarities include common organelles like cell membrane, cell nucleus, mitochondria, endoplasmic reticulum, ribosomes and golgi apparatus
Explanation:
hey both contain membrane-bound organelles such as the nucleus, mitochondria, endoplasmic reticulum, golgi apparatus, lysosomes, and peroxisomes.
The mass of an atom comes from the protons and neutrons
that are found in the nucleus. The number of protons is the atomic number of an
element. To find the number of neutrons, subtract the atomic number from the
mass of an atom. The atomic number is 8 and the atomic mass is 16.
Answer:
Option A
Explanation:
The total heat absorbed during the chemical reaction is the total heat released by the surrounding.
Net change of heat is equal to zero
Hence, the energy liberated from the air or the walls of the containers would be equal to the energy absorbed by the chemical reactions is equal to 100 Kj
Thus, option A is correct
