Water causes many electrolytes to dissociate __________.

Chemistry
1 answer:
lana66690 [7]3 years ago
8 0

Answer:

2. because water molecules are dipoles and the dipoles orient in an energetically favorable manner to solvate the ions.

Explanation:

For the water to dissociate electrolytes, this one has to orientate its molecules in an energetically favorable way that allows them to interact with ions and dissociate electrolytes. This has to do with the way that intermolecular forces of a solute and a solvent, which is the water, interact to form a solution. The different intermolecular forces that interact in a solution are dipole-dipole force, ion-dipole interactions, Van Der Waals forces, and Hydrogen bonding.

ankoles [38]

Answer:

Explanation:

It could be as a result of evaporation from the hot water causing it to have less mass than usual. Evaporation will allow the volume of the hot water to decrease and by so doing will cool faster than cold water which is at a higher mass. This is how I will explain my observations to them.

How many grams of chromium are required to react with 125ml of 0.75m cuso4?
evablogger [386]
Chromium and copper (ii) sulfate react according the reaction below;
 2Cr + 3CuSO4 = 3Cu +Cr2(SO4)3
We can calculate the number of moles of CuSO4 present;
no of moles of CuSO4 = 0.75 × 0.125 = 0.09735 moles
According to the reaction the mole ratio is 2 : 3
Moles of Chromium = (0.09735 × 2)/3
                                = 0.0625 Moles
Mass of chromium = 0.0625 moles × 52 g/mole 
                               = 3.25 g of chromium

Answer:

2 chloride ion, Cl¯

Explanation:

The formula for calcium chloride is CaCl₂.

Next, we shall write the balanced dissociation equation for calcium chloride, CaCl₂. This is illustrated below:

CaCl₂ (aq) —> Ca²⁺ + 2Cl¯

From the balanced equation above,

We can see that calcium chloride, CaCl₂ contains 1 calcium ion, Ca²⁺ and 2 chloride ion, Cl¯.

Therefore, we can conclude that for every 1 calcium ion, Ca²⁺, there are 2 chloride ion, Cl¯.
