Balance the following equation. Then determine the mole ratio of Ca(OH)2:Al(OH)3. Al2(SO4)3 + Ca(OH)2 Al(OH)3 + CaSO4

Answers

Answer 1

Answer: To balance the reaction, we look at the number of atoms of each element we have. It should be equal for both sides. The balanced reaction is:

Al2(SO4)3 + 3Ca(OH)2 = 2Al(OH)3 + 3CaSO4

The ratio of calcium hydroxide and aluminum hydroxide is 3:2.

Answer 2

Answer:

Answer: The mole ratio of $Ca(OH)_2:Al(OH)_3$ is 3 : 2

Explanation:

Law of conservation of mass states that mass can neither be created nor be destroyed, but it can only be transformed from one form to another. In a chemical reaction, total number of individual atoms on reactant side must be equal to the total number of individual atoms on the product side.

All the balanced chemical equation follows law of conservation of mass.

The balanced chemical equation for the combination of aluminium sulfate with calcium hydroxide is:

$Al_2(SO_4)_3+3Ca(OH)_2\rightarrow 2Al(OH)_3+3CaSO_4$

Mole ratio of any two compounds is basically the ratio of their stoichiometric coefficients.

Hence, the mole ratio of $Ca(OH)_2:Al(OH)_3$ is 3 : 2

Which missing item would complete this beta decay reaction?

Answers

The question is incomplete. Complete question is attached below:
.................................................................................................................

Correct Answer is : 54 131Xe

Reason:
Emission of beta particle from radioactive material increases atomic number by one, but atomic mass number donot change.

In present case, the reactant is 53 131 I. When, iodine emits beta particle i.e. electron, it atomic number increases by one. Hence, it gets converted into Xe. Atomic number of Xenon is 54.

The equation must include the parent and the daughter nucleus as well as the particle emitted.

What is beta decay?

A beta decay is said to occur when an electron is emitted from an atom. In this case, the daughter nucleus is greater in atomic number than the parent nucleus by one unit.

The question is incomplete. However, the equation must include the parent and the daughter nucleus as well as the particle emitted.

Great amounts of atomic energy are released when a _______reaction occurs.

Answers

Great amounts of atomic energy are released when a _______reaction occurs.

Great amounts of atomic energy are released when a chemical reaction occurs. The process can be an exothermic reaction or endothermic reaction depending on the substances involved in the reaction.

Substances with a higher temperaturea. have less thermal energy.
b. have more molecular disorder.
c. become more orderly if heated more.
d. will move thermal energy to a hotter substance.

Answers

B. High temp = more thermal energy =more disorder as molecules move randomly = move from hot to colder substance(heat moves from hot to cold)

Answer:

b is the corect awnser

Explanation:

Which molecule, when added to a solution, would give the solution the highest pH?HCl
H2SO4
KOH
H2O

Answers

The molecule, when added to a solution, would give the solution the highest pH is KOH. This is because when KOH is in the solution, it will give a very strong basic properties due to the -OH and the K which is highly electropositive.

Answer:

The answer is C.

Explanation:

Because, KOH is the highest PH in the molecule(s).

Find the molar mass of vitamin A (C20H30O).

Answers

Just add up the molar masses of each element.

Molar mass of C: 12.011 g/mol
The equation says C20, which means there are 20 carbon atoms in each molecule of Vitamin A. So, we multiply 12.011 by 20 to get 240.22 g/mol carbon.

Molar mass of H: 1.0079 g/mol
The equation says C30, which means there are 30 hydrogen atoms in each molecule of Vitamin A. So, we multiply 1.0079 by 30 to get 30.237 g/mol hydrogen.

Molar mass of O: 15.999 g/mol
The equation says O without a number, which means there is only one oxygen atom in each molecule of Vitamin A. So, we leave O at 15.999 g/mol.

Then, just add it up:
240.22 g/mol C + 30.237 g/mol H + 15.999 g/mol O = 286.456 g/mol C20H30O

So, the molar mass of Vitamin A, C20H30O, is approximately 286.5 g/mol.
