If a 250 mL glass of water contained 5.00 ppb, what mass of lead is in the glass of water? Assume the water in the glass has a density of 1.00 g/mL.
Which of the following given statements is false?
1. The electrical conductivity of water is dependent on the temperature of the water sample.
Removal of suspended particles by sedimentation depends upon the size and specific gravity of those particles.
Suspended solids retained on a filter may remain in suspension if their specific gravity is similar to water while very dense particles passing through the filter may settle.
Sodium hydroxide and sodium chloride are both bases.
2. In a sedimentation process, the solid particles settled at the bottom of the container because they are heavier than water and are acted upon by gravity.
In the process of distillation, the condenser helps in the conversion of the vapor that goes inside it into liquid.
After filtering a mixture using a filter paper, there is more solute at the bottom of the container compared to the contents of the filter paper.
In the reaction between dry ferrous sulfate and dry potassium ferricyanide, no change is observed.…
If we have a salt solution with a density of 1.2g/cm^3 and a metal bar with a density of 8.96g/cm^3, which one occupies a larger volume if we have 100g of each substance? I got that salt had a volume of 83ml and copper of 11.16ml. Why does the salt take up more volume? Doesn't it dissolve in the water?
