How can the conductivity of a salt solution be decreased?

Chemistry
1 answer:
Musya8 [376]2 years ago
4 0

Answer:

B. Add more water to decrease the concentration.

Explanation:

If we add more water to the solution, the concentration is decreased and like wise the conductivity of the solution.

  • Concentration is the amount of solute in a solution.
  • Conductivity deals with the ability of a solution to allow the passage of current.

Concentration and conductivity are directly proportional to one another. The higher the concentration, the higher the conductivity and vice versa.

  • Adding more water increases the amount of solvent and the concentration reduces.

Deffense [45]

Answer:

Dimer of two peptide chains with 1 mole of molybdenum metal each.

Explanation:

Percentage of molybdenum in protein = 0.08%

Molecular mass of nitrate reductase = 240,000 g

Mass of molybdenum = x

0.08\%=\frac{x}{240,000 g}\times 100=192 g

Moles of molybdenum =\frac{192 g}{95.95 g/mol}=2.00 mol

Each peptide chain of nitrate reductase contain 1 mole of molybdenum.

This means that nitrate reductase is composed of to two peptide chains. And in each peptide there is a single mole of molybdenum metal.

H+(aq) + OH–(aq) → H2O(l) + 55.8 kJ In this reaction there is conservation of
pentagon [3]
In the equation given above, there is conservation of MASS, CHARGE AND ENERGY.
These three parameters are usually conserved during the course of chemical reactions. When any of these parameter experience a reduction during the course of chemical reaction, such loss is always gained by other elements involved in the same reaction, so that at the end of the day, they are not considered as lost.

Which law is based on the graph that is shown below? A graph is shown with pressure on the horizontal axis and volume on the ver
DIA [1.3K]

<u>Answer:</u>

"Boyle's Law" is based on the graph that is shown below.

<u>Explanation:</u>

Boyle's law or Boyle – Mariotte law or Mariotte's law, is an experimental gas law that discusses how a gas's pressure tends to rise as the container volume start declining. This shows the relationship between pressure and volume for a fixed mass at a constant temperature, i.e., number of a gas molecules.This rule visualizes the actions of gas molecules in a confined space. This law can be understood from following equation:

p₁V₁ = p₂V₂

Above the product of the initial volume and pressure is equal to the product of the volume and pressure after a change.

Analysis/Conclusions:
Paha777 [63]
The correct answers are as follows:
1. MgSO4 + 2NH4OH = [NH4]2SO4 + Mg[OH]2.
This chemical equation implies that, one molecule of magnesium sulphate react with two molecules of ammonium hydroxide to give rise to one molecule of ammonium sulphate and  one molecule of magnesium hydroxide. 
2. The reaction between magnesium sulphate and ammonia is a DOUBLE REPLACEMENT REACTION.
A double replacement reaction is a type of reaction in which the two chemical substances which take part in the reaction switch their ions in such a way that two new products are formed. In the reaction of magnesium sulphate and ammonia, the magnesium sulphate gives its SO4 ion to ammonia and take the OH ion of the ammonia instead. 
3. The epsom salt and the ammonia reacted. This is made obvious by the chemical reaction which was generated by their combination. On the edge of the penny used, one can see that there is a colour change, this shows that a chemical reaction occur.
