What is a chemical bond?a. a representation of chemical properties
b. a substance that's composed of atoms
c. the force that holds together the elements in a compound
d. the attraction of two atoms that holds the atoms togethe?

Answers

Answer: -

A chemical bond is

C) the force that holds together the elements in a compound.

Explanation: -

A chemical bond results when there is a transfer of electrons from 1 element to another or there is a sharing of electrons between two element atoms.

Due to this compounds are formed.

Hence A chemical bond is

C) the force that holds together the elements in a compound.

the correct answer should be c.

In a synthesis reaction you start with 1.7L of hydrogen, how many liters of water will be produced

Answers

Answer:

1.7L of water.

Explanation:

Given parameters:

Volume of hydrogen gas = 1.7L

Unknown:

Volume of water produced = ?

Solution:

A synthesis reaction is one in which two compounds or molecules combines together to give a product or products.

Synthesis of water from hydrogen gas is represented by the equation below:

2H₂ + O₂ → 2H₂O

We clearly see that;

2 mole of hydrogen gas gives 2 mole of water as the product;

From Gay-lussac's law of combining volume "when gases react, they do so in volumes which bear a simple ratio to one another and to the volume of the product if gaseous, temperature and pressure remaining constant".

2H₂ + O₂ → 2H₂O

2 volumes of hydrogen gas will produce 2 volumes of water

1.7L of hydrogen gas will also produce ; 1.7L of water.

If I add 25mL of water to 125 mL of 0.25 M NaOH solution, what will the molarity of the diluted solution be?

Answers

Answer:

0.208333 M

Explanation:

M2=M1V1/V2=(0.25 M)(125mL)/(125mL+25 mL)= 0.208333 M

Which law states that the volume of a gas is proportional to the moles of the gas when pressure and temperature are kept constant?

Answers

I believe this would be Avogadro's law which states ''Equal volumes of all gases, at the same temperature and pressure, have the same number of molecules regardless of their chemical nature and physical properties.''
