Answer:a) 0.1 mole. b) 4g. c) 2% d)  196 mL

Explanation: in 200mL , 0.1mole

mw NaOH = 40g/mol —> 4g in 0.1 mole

4g in 200mL so 2g in 100mL

density NaOH = 1g/mL so if 4g in 200 mL,  4mL , 196 mL water

How would you describe (explain the differences) solids, liquids, and gases to a 4th grader? Be clear please.
musickatia [10]
A solid is an object that has definite shape, volume, and mass. This means that the shape, volume, and mass will never change.

A liquid is something that has definite volume and mass, but it does not have definite shape because a liquid is the shape of its container.

A gas <span>does not have a definite shape, mass, or <span>volume because a gas is able to spread around.</span></span>

What are the electrons capable of Sharing accepting or donating called?
Oliga [24]
Substances have different tendencies to donate or accept electrons. When a really good donor meets a great acceptor, the chemical reaction releases a lot of energy. Oxygen (O2) is the best electron acceptor and is used in many aerobic reactions (reactions with oxygen). Hydrogen gas (H2) is a good electron donor.

When O2 and H2 are combined, along with a catalyst, water (H2O) is formed. This example of a redox reaction can be written like this:
