1) protons have a positive charge
2) electrons have a negative charge
3) neutrons have a neutral charge
Answer:
The molarity of the Pb(NO3)2 solution is 0.24 M
Explanation:
Assuming there was no loss during filtration, we can calculated amount of moles Pb(NO3)2 from the 13.25 g of PbCl2 ussing molar mass of PbCl2
13.25 g / 278.1 g = 0.04 moles of PbCl2
According balanced equation 2NaCl + Pb(NO3)2 = 2NaNO3 + PbCl2, 1 mol of Pb(NO3)2 produces 1 mol of PbCl2. So, 0.04 moles of Pb(NO3)2 produces PbCl2
Molarity is = moles of solute/volumen of solution (L)=0.04/0.2= 0.24

The answer to this question is C. Freezing, hope this helps :)
Non-polar.
This is because there are no lone pair valence electrons on the central atom (Carbon) when this is plotted on a Lewis Dot Structure.
Since Oxygen double bonds and Carbon holds 4 valence electrons, all center electrons are paired, thus sharing everything equally and making the molecule non-polar.
Hope this helps!
The answer is the magnetosphere
