A salt water solution is 58g. After the water evaportes, what is the amount of salt left in the cup?
reactants
Cup 1 is less dense and less concentrated than Cup 2.
True
8g
saturated
The marble is more dense than the water.
There is a solid powder at the bottom of the cup.
Solution A
Two cups have the same amount of water. Cup 1 has 30g of salt. Cup 2 has 44g of salt. How does the density and concentration Cup 1 compare to Cup 2?
reactants
Cup 1 is less dense and less concentrated than Cup 2.
True
8g
saturated
The marble is more dense than the water.
There is a solid powder at the bottom of the cup.
Solution A
A solution that cannot dissolve any more solute and the solute sinks to the bottom is said to be
reactants
Cup 1 is less dense and less concentrated than Cup 2.
True
8g
saturated
The marble is more dense than the water.
There is a solid powder at the bottom of the cup.
Solution A
A boy puts a marble in water and it sinks. This tells the boy that
reactants
Cup 1 is less dense and less concentrated than Cup 2.
True
8g
saturated
The marble is more dense than the water.
There is a solid powder at the bottom of the cup.
Solution A
The original substances that are present before a chemical reaction are called
reactants
Cup 1 is less dense and less concentrated than Cup 2.
True
8g
saturated
The marble is more dense than the water.
There is a solid powder at the bottom of the cup.
Solution A
A student mixes a colorless liquid and a blue solid. When all of the solid dissolves, the liquid is blue. After 10 minutes, a solid powder appears on the bottom of the cup. What is the evidence that a chemical reaction occurred?
reactants
Cup 1 is less dense and less concentrated than Cup 2.
True
8g
saturated
The marble is more dense than the water.
There is a solid powder at the bottom of the cup.
Solution A
It a solution is more concentrated than another, then it has a greater mass and weighs more.
reactants
Cup 1 is less dense and less concentrated than Cup 2.
True
8g
saturated
The marble is more dense than the water.
There is a solid powder at the bottom of the cup.
Solution A
Solution A has 8g of solid. Solution B has 10g of solid. Which solution is the least concentrated?
reactants
Cup 1 is less dense and less concentrated than Cup 2.
True
8g
saturated
The marble is more dense than the water.
There is a solid powder at the bottom of the cup.
