Answer:
It is called the formula unit
b. 4
c. 8
d. 10
e. 13
Explanation:
In chemistry, internodes refer to the points in the structure of a molecule or molecular chain where carbon atoms are located. Internodes are carbon atoms that are directly connected by a single bond. These carbon atoms are often called "C" followed by a number indicating their position in the chain. Carbon atoms that are not internodes are called "terminal carbons" and are bonded to other atoms or chemical groups. The structure of internodes and terminal carbons is important for understanding the geometry and reactivity of organic molecules.

Hello!
Find the empirical formula of a compound which contains 54.93% potassium, 38.73% boron and 6.34% hydrogen.
A. KBH
B. KB2H4
C. KB3H9
D. K2B5H9
Potassium (K) ≈ 39 a.m.u (g/mol)
Boron (B) ≈ 11 a.m.u (g/mol)
Hydrogen (H) ≈ 1 a.m.u (g/mol)
K: 54.93 % = 54.93 g
B: 38.73 % = 38.73 g
H: 6.34 % = 6.34 g
convert number of atomic radio into whole number
2 * (1 : 2.5 : 4.5)
= 2 : 5 : 9 ← whole number of atomic radio
K = 2
B = 5
H = 9
Answer:
D. K2B5H9

B. saponification
C. ionization
D. neutralization
Answer: D. neutralization
Explanation:
1. Substitution reaction is defined as the reaction in which one atom replaces the other atom from the compound.
2. Saponification is a reaction in which fatty acids are made to react with alkalis to form sodium salt of fatty acids called as soaps.
3. Ionization is a type of chemical reaction in which a substance ionizes when dissolved in water.
4. Neutralization is a type of chemical reaction in which an acid reacts with base to produce salt and water.
