A buffer is a solution which resists changes to it pH when a small quantity of acid or base is added to it.
<h3>What is a buffer?</h3>
A buffer is a solution which resists changes to it pH when a small quantity of acid or base is added to it.
Buffers are made from solutions of weak acids and their salts or weak bases and their salts.
<h3>What is pH?</h3>
The pH of a solution is the negative logarithm to base 10 of yhe hydrogen ion concentration of the solution.
Solutions of low pH have high concentration of hydrogen ions while solutions of high pH have high hydrogen ion concentration.

Answer:
Temperature on beans sprouted
Explanation:
- The variable amount is the amount that changes continuously.
- We calculate the sprout of the bean at which temperature it is sprouting rapid, in that case, the temperature acts as a variable amount.
Answer:
The relationship of pH and concentration of H+ ion is pH = -lg[H+]. So the concentration of H+ is 10^(-2). And [OH-][H+]=10^(-14). pOH + pH = 14. So the right answer is A.
The relative abundance and the mass number usually they give these to you. They give me both these values in my chemistry class so i just multiply add the products and get my answer
Chromosomes have hereditary function
that are capable of self-duplication and they have thread-like structures seen
inside the nucleus of plant and animal. In plants, they go through a cycle
called alteration of generation that has multicellular stages. One is sporophyte
that is a diploid, and the other is gametophyte with a haploid.
<span>Moreover, spores are produce through
meiosis so it go through a process of chromosome reduction in order to create a
haploid spores. While, gametes undergo mitosis and the structure is already a haploid,
which means that the number of chromosomes will not change in order to produce
haploid. In this case, the plant have both spores and gametes and the
similarities is that, they are both singles celled and a haploid. Therefore,
the number of the chromosome in the gametophyte generation is also 32.</span>
