Don't ever return unused chemicals to their original containers. If you do, you could be
contaminating the chemical. Discard the leftover chemical in the correct waste
box. Ask your teacher if your not sure about what to do.
In the Proton category: symbol p, and +1 charge
In the Neutron category: symbol n, 0 charge
In the Electron category: symbol e, -1 charge
Answer:
A) 3.59 cm
Explanation:
Given that :-
The density of the gold ingot = 
Given that:- Mass = 5.50 lbs
Also, considering the conversion of lbs to g as shown below:-
1 lb = 453.592 g
Thus,
Mass = 
= 2494.756 g
The volume = Length*Breadth*Height
Given that:- Length = 12.0 cm , Breadth = 3.00 cm
Considering the expression for density as:-
Solving for height, we get that:-
Height=3.59 cm
Answer:
Dipole-Dipole attraction
Explanation:
Dipole-dipole attraction is a type of vander waals forces found in the molecules of sulfur dioxide.
Vander waals forces are weak attractions joining non-polar and polar molecules together. They are of two types:
- London dispersion forces which are weak attractions found between non-polar molecules.
- Dipole-Dipole attraction are the forces of attraction which exists between polar molecules. Such molecules have permanent dipoles. This implies that the positive pole of one molecule attracts the negative pole of another. This is what happens between the oxygen and sulfur molecules.
In collecting the precipitate, it is inappropriate to heat <span>the reacted mixture and evaporate off the water because it is possible that the mixture contains other substances that precipitates as well when the mixture is being heated so you will not be able to collect what you want.</span>
