jenny dissolves as much salt as she can in 100mL of room temperature water. she learned in class that less salt will dissolve in
cold water than hot water. jenny adds some ice in the salt water and observes what happens. what effect will adding the ice solution have on the amount of salt that can be dissolved into it ?
The solubility of the salt will decrease upon addition of ice.
Explanation:
The question already stated explicitly that; 'she learned in class that less salt will dissolve in cold water than hot water.' This implies that addition of ice will lower the temperature of the water (bring it near ice point) thereby decreasing the solubility of the salt in water and the solid salt crystals will reappear visibly at lower temperature of solution.
The chemical formula for magnesium sulfate is MgSO4, so it shows that there are four atoms of oxygen but not sulfur. There is only one atom of sulfur in the formula
The given compounds have been arranged from left to right in order of increasing percentage by mass of hydrogen.
The percent by mass of hydrogen can be calculated by mass of hydrogen in that compound divided by total mass of that compound and finally multiplying the result with 100 to obtain the required percentage.
