Hey there!
Your answer is B. MgCl.
This is because this isn't an actual existing compound.
Water (H₂O) and magnesium chloride (MgCl₂) are both real compounds, but the number of electrons does not line up to make MgCl possible.
Hope this helps!
By a process called osmosis. osmosis depends on the concentration of the water inside and outside the cell
The branched structure isomer will require less energy to melt than the straight chain isomer
explanation
Branched structure isomer has weak intermolecular forces of attraction as compared to straight chain isomers. In addition the branched isomer has a low boiling point as compared to straight chain isomers. Since boiling require the of the intermolecular forces tend to have lower boiling point than straight chain
Explanation:
Silver nitrate + iron (III) chloride --> silver chloride + iron (III) nitrate
The balanced chemical equation is given as;
2FeCl3 + 3Pb(NO3)2 → 2Fe(NO3)3 + 3PbCl2
Mass of Pb(NO3)2 = 25g
How many grams of iron (III) nitrate were formed?
From the equation;
3 mol of Pb(NO3)2 produces 2 mol of Fe(NO3)3
Converting to mass using;
Mass = Number of moles * Molar mass
Pb(NO3)2;
Mass = 3 mol * 331.2 g/mol
Mass = 993.6 g
Fe(NO3)3;
Mass = 2 mol * 241.86 g/mol
Mass = 483.72 g
This means 993.6 g produces 483.72 g
We have;
993.6 g = 483.72 g
25 g = x
solving for x;
x = 25 * 483.72 / 993.6
x = 12.1709 g of iron (III) nitrate
