A beaker and a microscope
Answer:
B
Explanation:
Because the particles in gases are much further apart than in liquids or solids, they can be squeezed closer together. Gases therefore can be compressed or expanded. They do not have a fixed volume
Answer:
the attractive force between two objects with opposite charges, two objects that are of like charge will repel each other. That is, a positively charged object will exert a repulsive force upon a second positively charged object.
Explanation:
Answer:
To make a 3.50 M solution, 38.5 moles of solute will be needed if 11 liters of solution are required.
Explanation:
Molarity is defined as a concentration unit that indicates the number of moles of solute per liter of solution. That is, it indicates the number of moles of solute that are dissolved in a given volume. Then, the molarity is calculated by dividing the moles of the solute by the liters (volume) of the solution:
Molarity is expressed in units ().
So, knowing the definition of molarity, you can apply a rule of three as follows: if by the definition of molarity in 1 L of solution there are 3.5 moles of solute, in 11 L of solution how many moles of solute are there?
moles=38.5
