Answer:
94.8% is the percentage yield of this reaction.
Explanation:
Mass of aluminium = 3.8 g
Moles of aluminium =
According to reaction, 2 moles of aluminum gives 2 moles of aluminium chloride, then 0.1407 moles of aluminium will give:
aluminium chloride
Mass of 0.1407 moles of aluminum chloride:
= 0.1407 mol × 133.5 g/mol = 18.78 g
Theoretical yield of aluminum chloride = 18.78 g
Experimental yield of aluminum chloride = 17.8 g
The percentage yield of reaction:
94.8% is the percentage yield of this reaction.
Given data:
Diameter of the gold wire (d) = 0.175 cm
Length of the gold wire (l) = 1.00 * cm
Volume of the given gold wire = volume occupied by a cylindrical object\
= π * *l
here r = radius of the cross section
where : r = d/2
Hence the volume V = π * *l
=
Density of gold = 19.3 g/cm3
Weight of the gold wire = Density * volume
= *
=
Answer:
being responsible is owing up to the possible
consequences of your decision whether it was right or wrong.
communication is a two way process in which there is a messenger and receiver
one of the ways by which a person could be responsible is by saying 'I'
in all the things he would say, instead of 'we'
for example , " We don't like the way you acted a while ago " , change it to i don't like tye way you acted a while ago.
here u r establishing ownership on the things you want to say to the person
