Answers

Answer 1

Answer:

In an ionic compound, the smallest whole-number ratio of positive and negative ions that results in a neutral unit is called the formula unit.

What is ionic compound?

The compound formed by the ionic bond is called ionic compound.

The ionic compound is stronger than covalent compound.

The ionic compound contains positive part called cation and negative part called an anion.

Example: sodium chloride ( $NaCl$ )

What is ionic bond?

The bond formed by the complete transfer of electrons is called ionic bond.

What is internodes in chemistry

Answers

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.

Find the empirical formula of a compound which contains 54.93% potassium, 38.73% boron and 6.34% hydrogen.A.

Answers

Use the percent as mass in g
Mass g) --> g/mol
K, B and H molar mass from periodic table

54.93 g K x (1 mol K/ 39.10 g K) = 1.405 mol K
38.73 g B x (1 mol B/ 10.81 g B) = 3.583 mol B
6.34 g H x (1 mol H/ 1.008 g H) = 6.290 mol H

Divide all three answers by the smallest value and you will get
1.000 mol K
2.550 mol B
4.477 mol H
now multiply these three answers by a number that will make all a whole number or (a number with a 9 as the first decimal point)
so multiply by 2
2 mol k
5 mol B
and 9 mol H

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

We have the following data:

Potassium (K) ≈ 39 a.m.u (g/mol)

Boron (B) ≈ 11 a.m.u (g/mol)

Hydrogen (H) ≈ 1 a.m.u (g/mol)

We use the amount in grams (mass ratio) based on the composition of the elements, see: (in 100g solution)

K: 54.93 % = 54.93 g

B: 38.73 % = 38.73 g

H: 6.34 % = 6.34 g

The values (in g) will be converted into quantity of substance (number of mols), dividing by molecular weight (g / mol) each of the values, we will see:

$K: (54.93\:\diagup\!\!\!\!\!g)/(39\:\diagup\!\!\!\!\!g/mol) \approx 1.408\:mol$

$B: (38.73\:\diagup\!\!\!\!\!g)/(11\:\diagup\!\!\!\!\!g/mol) \approx 3.521\:mol$

$H: (6.34\:\diagup\!\!\!\!\!g)/(1\:\diagup\!\!\!\!\!g/mol) = 6.34\:mol$

We realize that the values found above are not integers, so we divide these values by the smallest of them, so that the proportion does not change, let us see:

$K: (1.408)/(1.408)\to\:\:\boxed{K = 1}$

$B: (3.521)/(1.408)\to\:\:\boxed{B \approx 2.5}$

$H: (6.34)/(1.408)\to\:\:\boxed{H \approx 4.5}$

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

Thus, the minimum or empirical formula found for the compound will be:

$\boxed{\boxed{K_2B_5H_9}}\Longleftarrow(Empirical\:Formula)\:\:\:\:\:\:\bf\green{\checkmark}$

Answer:

D. K2B5H9

Chemical changes do not form new compounds

do not decompose the old compounds

form new compounds

change the appearance of the old compounds

Answers

The correct answer is that chemical changes form new compounds. Chemical change is a change where the substance changes in identity or form new substances after undergoing a process. On the other hand, a physical change is a change in the properties of matter that does not change the identity of the substance.

Which reaction occurs when hydrogen ions react with hydroxide ions to form water?A. substitution
B. saponification
C. ionization
D. neutralization

Answers

Answer: D. neutralization

Explanation:

1. Substitution reaction is defined as the reaction in which one atom replaces the other atom from the compound.

$AB+C\rightarrow AC+B$

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.

$AB\rightarrow A^++B^-$

4. Neutralization is a type of chemical reaction in which an acid reacts with base to produce salt and water.

$BOH+HX\rightarrow BX+H_2O$

The answer is D.This one is a bit tricky because it requires you to realize that H+ and OH- are, respectively, an acid and a base. That's why it's neutralization.
