Answer:
D) forms hydronium ions in water
Explanation:
Texture and conductivity are physical properties which makes answer A and B wrong. Answer C does not refer to a chemical reaction.
First, we have to remember the molarity formula:

Part 1:
In this case, our solute is sodium nitrate (NaNO3), and we have the mass dissolved in water, then we have to convert grams to moles. For that, we need the molecular weight:

Then, we calculate the moles present in the solution:

Now, we have the necessary data to calculate the molarity (with the solution volume of 200 mL):

The molarity of this solution equals 0.2339 M.
Part 2:
In this case, we have the same amount (in moles and mass) of sodium nitrate, but a different volume of solution, then we only have to change it:

So, the molarity of this solution is 0.1701 M.
Answer:
naoh is called sodium hydroxide,

WHAT THE HECK!?!?!?! AM I SUPPOSE TO KNOW WHATEVER LANGUAGE THAT IS?!?!
Answer:
1. C 2. B 3. A
Explanation:
1. Gay- Lussac law, states that as along as the volume is kept constant, the pressure of a fixed mass of gas is directly proportional to the temperature.
The properties it compares is; (c.) Pressure and temperature
2. Boyle's Law states that; as long as the temperature is kept constant, the volume of a fixed mass of gas is inversely proportional to the pressure.
It therefore compares; (b.) Pressure and volume
3. Avogadro's Law states that equal volumes of different gases contain the same number of molecules provided the temperature and pressure are the same.
It therefore compares; (a.) Volume and moles
