Quantitative is anything that is relating to a number value. Think “quantity”
Example:
1. There are 5 ml of water
2. There are 3 beakers
3. It takes 30 minutes for the reaction
Qualitative is about characteristics that can be described
Example
1. The liquid is green
2. The solution turned into a gas
3. Bubbles were produced
The molarity of a solution if it tale 12.0 grams of Ca(No3)2 is calculated as below
molarity = moles/volume in liters
moles = mass/molar mass = 12.0 g/ 164 g/mol = 0.073 moles
molarity is therefore = 0.073/0.105 = 0.7 M
Answer:
A molecule of water has two hydrogen atoms. Both of these atoms can form a hydrogen bond with oxygen atoms of different water molecules. Every water molecule can be hydrogen bonded with up to three other water molecules
Answer:
B. Beryllium
Explanation:
because the trend of ionization is going up a group it increases, as going across a period it deceases. beryllium being closes to the hist point in the periodic table it has the highest ionization energy. hope this helps.
Answer:
