The correct classification of the solutes are as follows:
<span>hydroiodic acid hi = strong electrolyte
calcium hydroxide ca(oh)2 = weak electrolyte
hydrofluoric acid hf = weak electrolyte
methyl amine ch3nh2 = weak electrolyte
sodium bromide nabr = strong electrolyte
propanol c3h7oh = non electrolyte
sucrose c12h22o11 = non electrolyte
Strong electrolytes are substances that completely ionizes in aqueous solution while weak electrolytes are those that partially ionizes. Non electrolytes are substances that cannot conduct electric charge since there are no ions in the solution.</span>
It is a moderate conductor of electricity, and in nature it is a dark indigo blue mineral. Density: 4.6g/cm^3. insoluble in water. melting point above 500 degrees C.
During the big band only the lightest elements were formed – hydrogen<span> and </span>helium<span> along with trace amounts of </span>lithium<span> and </span>beryllium<span>.</span>
Answer:
You have to prepare for the lab (Materials, work, paper etc.)
Set up the lab know where the lab will be taking place
Read thru the experiment before doing the lab
Make a hypothesis
Write down notes, observations, measures anything important to help with the lab!
Additional information
Relative atomic mass(Ar) : A=7, G=16
The empirical formula : A₂G
<h3>Further explanation</h3>
Given
3.5g of element A
4.0g of element G
Required
the empirical formula for this compound
Solution
The empirical formula is the smallest comparison of atoms of compound forming elements.
The empirical formula also shows the simplest mole ratio of the constituent elements of the compound
mol of element A :
mol of element G :
mol ratio A : G = 0.5 : 0.25 = 2 : 1
