Answer:
Everything that has mass and takes up space is matter. Every day, you encounter phenomena that either don't have mass or don't take up space. They are non-matter. Basically, any type of energy or any abstract concept is an example of something that is not matter.

Ca(OH)2 + 2HCl --> CaCl2 + 2H2O. So the amount of calcium hydroxide in the sample is ((19.50ml HCl)/1000) x 0.1050 mol/L
From the balanced equation above: (1 mol Ca(OH)2 / 2 mol HCl)
Calculating the amount of Ca(OH)2 in the 50ml sample, multiply with the molar mass:
((19.50ml HCl)/1000) x 0.1050 mol/L x (1 mol Ca(OH)2 / 2 mol HCl) x 74.039 g/mol

d. sunflower oil
Answers
Answer:
Canola Oil
Explanation:
The data given is as;
Oil Melting Point / Freezing Point
Canola Oil 10 °C
Corn Oil -11 °C
Sunflower Oil -17 °C
Peanut Oil -2 °C
When the mixture of these oils is cooled to 5 °C only the Canola oil will solidify because it has a melting point of 10 °C and exists in solid state below 10 °C (Freezing Point). Therefore, it can easily be separated from remaining mixture which is present in liquid state.

Answer:
Atomic radius of sodium = 227 pm
Atomic radius of potassium = 280 pm
Explanation:
Atomic radii trend along group:
As we move down the group atomic radii increased with increase of atomic number. The addition of electron in next level cause the atomic radii to increased. The hold of nucleus on valance shell become weaker because of shielding of electrons thus size of atom increased.
Consider the example of sodium and potassium.
Sodium is present above the potassium with in same group i.e, group one.
The atomic number of sodium is 11 and potassium 19.
So potassium will have larger atomic radius as compared to sodium.
Atomic radius of sodium = 227 pm
Atomic radius of potassium = 280 pm
