Explanation :
According to the Bronsted Lowry concept, Bronsted Lowry-acid is a substance that donates one or more hydrogen ion in a reaction and Bronsted Lowry-base is a substance that accepts one or more hydrogen ion in a reaction.
Or we can say that, conjugate acid is proton donor and conjugate base is proton acceptor.
The equilibrium reaction will be,
In this reaction, and are base and acid and and are conjugate acid and conjugate base respectively.
Ammonia is a weak base because it accept proton from the water and gives fewer hydroxide ions.
3,5, and 1 i think maybe i uhm yeah
Due to the conjugate base of the hydrogen atom is aromatic, Hb is regarded as the most acidic. Because the conjugate base of the hydrogen atom Hc is anti-aromatic, it is the least acidic.
The correct options are:
(A) - (a)
(B) - (d)
The hydrogen connected at the heptatriene's tertiary position (at the 7-methyl) would be particularly acidic, as its removal would leave a positive charge that could be transported around the ring via resonance.
The hydrogen connected to the pentadiene (5-methyl) at the tertiary position would not be acidic, as removing it would result in an anti-aromatic structure.
Thus, the least acidic H atom is Hc and the most acidic H atom is Hb.

A- Each Compound contains only one element.
B- Compound can be classified as either heterogenous or homogenous.
C- A Compound has a defined ratio by mass of the elements that it contains
D- Compounds Vary in chemical composition depending on the sample size.
The following statements about compounds is true that a compound has a defined ratio by mass of the elements that it contains. Option C is correct.
A compound is a substance that is made up of two or more elements that are chemically bonded together. The elements in a compound are always present in a fixed ratio by mass. This means that no matter how much of the compound you have, the ratio of the elements will always be the same.
For example, water is a compound that is made up of hydrogen and oxygen. The ratio of hydrogen to oxygen in water is always 2:1 by mass. This means that no matter how much water you have, there will always be twice as much hydrogen as oxygen.
A compound can be classified as either homogeneous or heterogeneous, but not both. Homogeneous compounds have a uniform composition throughout, while heterogeneous compounds have different compositions in different parts of the sample. Compounds do not vary in chemical composition depending on the sample size. The chemical composition of a compound is always the same, regardless of how much of the compound you have. Option C is correct.

Explanation:
A and D is the answer
Hope the answer is right
Answer:
a) V = 1.542 E11 ft³
b) V = 4367011968 m³
c) V = 1.1535 E12 us gal
Explanation:
Acre surface is defined as 66 by 660 feet at a depth of one foot:
⇒ Vacre-foot = 66ft*660ft*1ft = 43560 ft³
lake:
a) V = 3.54 E6 acre-feet * ( 43560 ft³ / acre-foot ) = 1.542 E11 ft³
b) V = 1.542 E11 ft³ * ( 0.02832m³ / ft³ ) = 4367011968 m³
c) V = 1.542 E11 ft³ * ( 7.48052 us gal/ft³ ) = 1.1535 E12 us gal

Answer:
Hence,
1) removed
2) drained through the stopcock
3) get eye level with
4) slow the draining
5) switch to a new flask
Explanation:
After mixing the solutions in a separatory funnel, the stopper should be removed and the liquid should be drained through the stopcock, and the layers allowed to separate. When you get close to the interface between the layers, get eye level with the funnel and turn over to slow the draining heat up until the first layer is collected. Switch to a new flask get eye level with it to collect the second layer.
