determine the solubility of kcl at 60 °c in 100g of h2o?

Answers

Answer 1

the solubility of kcl at 60 °c in 100g of h2o is about 45 g/100 g H2O

with a view to be capable of understand what's occurring while the solution is cooled from 60∘C to 0∘C , you want to look at the solubility graph for potassium chloride, KCl .
notice that the solubility curve shows that at 60∘C , potassium chloride has a solubility of about 45 g/100 g H2O .
What which means is that at that temperature, you may best dissolve 45 g of potassium chloride in step with 100 g of water. This genuine amount of potassium chloride will result in a saturated solution.
A saturated solution is an answer in that you have an equilibrium between the strong solute and debris of solute which can be being dissolved into answer

Answers

Electricity can be charged via a variety of techniques, such as frictional charging, contact charging, and induction charging.

What kind of material exhibits electrical conductivity?

For conducting electricity, metals like copper, iron, gold, aluminium, and silver work best. Via the electrodes in a standardised aqueous solution at a specific temperature, the electrical conductivity of a substance is measured.

How can you determine whether an element is a metal or a non-metal using electrical conductivity?

A substance is a metal if it conducts electricity and has a basic oxide. A non-metal is an element whose oxide is acidic but not electrically conducting.

Indicate the dostance that corresponds to the bond length of the N2 molecule by placing an X on the horizontal axis

Answers

To indicate the distance that corresponds to the bond length of the N₂ molecule, we need to know the bond length of the N₂ molecule. The bond length of a molecule refers to the distance between the nuclei of two bonded atoms.

The bond length of N₂ is approximately 109.76 picometers (pm). Therefore, to indicate the bond length of N₂ on the horizontal axis, we can place an X at 109.76 pm.

It's important to note that bond lengths can vary slightly depending on the specific conditions of a given experiment or calculation. However, the bond length of N₂ at standard conditions is well established, and 109.76 pm is a commonly accepted value.

Knowing the bond length of a molecule is important in understanding the nature of the chemical bond between two atoms. The bond length is related to the strength of the bond, with shorter bond lengths indicating stronger bonds. The bond length of N₂ , for example, is relatively short, indicating a strong bond between the two nitrogen atoms.
