What is the approximate size of solute particles in a solution?
murzikaleks [220]

The approximate size of solute particles in a solution is 1 nanometer.

Explanation:

Solute and solvent are the two components required to prepare a solution. Solute is the one which is dissolved in the solvent to prepare a solution. So solute should be of lesser concentration compared to the solvent. Also the particle size of solute should be lesser in size compared to the solvent for easy diffusion and substitution. Mostly it is seen that if the solute is finer and having a size of less than 1 nanometer can be easily dissolved in the solvent.

So for forming homogeneous solutions, the solute is considered to be of materials having the particle size of 1 nanometer for perfect dissolving.

Thus, the approximate size of solute particles in solution is 1 nanometer.

Convert 1.25 atm to bar.
Tasya [4]

Answer: 1.27 bar

Explanation:

1 atm = 1.01325 bar

1.25 atm = Z (let Z be the unknown value)

To get the value of Z, cross multiply

Z x 1 atm = 1.25 atm x 1.01325 bar

1 atm•Z = 1.2665625 atm•bar

To get the value of Z, divide both sides by 1 atm

1 atm•Z/1 atm = 1.2665625 atm•bar/1atm

Z = 1.2665625 bar

(Round up Z to the nearest hundredth as 1.27 bar)

Thus, 1.25 atm when coverted gives 1.27 bar

Can a combination reaction be a redox reaction ?
saul85 [17]

Answer:

Yes A redox reaction can be a combination reaction.

Two elements are mixed in a combination reaction to produce a single product.

Explanation:

Example: water formula

2H2 + O2 → 2H2O

Oxygen is reduced in this reaction when electrons are transferred from hydrogen to oxygen and hydrogen is also oxidized since oxygen from hydrogen accepts electrons. Oxygen is the oxidizing agent and hydrogen is the reducing agent.

2H2 + O2 → 2H2O
