Answer: An Acid is a substance that can donate H+ ion.

Explanation:

An Acid is any substance that can donate hydrogen ion and form covalent bond with electron pair. When an acid is dissolved in water, there is a shifted balance between the hydrogen ion and hydroxide ion leading to more hydrogen ion in water,which the the solution acidic. There are two classification of Acids, they are weak and strong acid.

A strong acid dissociate completely in aqueous solution, examples are Hydrochloric acid, tetraoxosulphate6 acid(HCl and H2S04) e.t.c

Weak acid don't dissociate in aqueous solution completely, examples include citric acid, oxalic acid, carbonic acid e.t.c

if the ratio of the ages of kisii and esinam is 3:5 and that of Esinam and Larry is 3:5 and the sum of the ages of all three is
larisa [96]

Answer:

The age difference between the oldest and the youngest is 48.

Explanation:

Given the following data;

The ratio of the ages of Kisii (K) and Esinam (E) is 3:5.

The ratio of the ages of Esinam (E) and Larry (L) is 3:5.

The sum of the ages of all three is 147.

Since the age of Esinam is common in both ratios, we find the lowest common multiple (LCM);

LCM of 3,5 = 15.

Hence, the ratio of the three ages is now;

K:E:L = 9:15:25

Let their ages be denoted by x;

K:E:L = 9x:15x:25x

The sum of all three ages is;

9x + 15x + 25x = 147

49x = 147

x = 147/49

x = 3.

To find the age difference between the oldest and the youngest;

The oldest is Esinam = 25x

The youngest is Kisii = 9x

Therefore, 25x - 9x = 16x

Substituting the value of x, we have;

x = 3; 16x = 16(3) = 48.

The age difference between the oldest and the youngest is 48.

Complete the phrase below. Each member must contribute one complete sentence. The words prokaryotic and eukaryotic must be used:
ankoles [38]

Answer/Explanation:

All cells are not the same because not all cells contain membrane-bound organelles.

Prokaryotic cells lack membrane-bound organelles. In contrast, eukaryotic cells contain membrane-bound organelles like an endoplasmic reticulum, lysosomes, and importantly, a nucleus.

The nucleus is where genetic information (DNA) is stored. However, it is only present in eukaryotic cells. Prokaryotic cells do not possess a nucleus, the DNA is found in the cytoplasm.
