Give three examples of electron configuration‘s for atoms on the periodic table with the same activity that can be attribute it to there being two electrons in the outer most energy level.

pls idk what this means or how to do it : )

c.ocean winds can carry moisture with them and can bring rain and fog over inland areas

answer: the theoretical yield of solid lead comes out to be 5.408 grams.

explanation:

to calculate the moles, we use the following equation:  

given mass of lead nitrate = 8.65 grams

molar mass of lead nitrate = 331.2 g/mol

putting values in above equation, we get:

given mass of aluminium = 2.5 grams

molar mass of aluminium = 27 g/mol

putting values in above equation, we get:

for the given chemical reaction, the equation follows:

by stoichiometry:

3 moles of lead nitrate reacts with 2 moles of aluminium

so, 0.0261 moles of lead nitrate are produced by = of aluminium.

as, the required amount of aluminium is less than the given amount. hence, it is considered as the excess reagent.

lead nitrate is considered as a limiting reagent because it limits the formation of product.

by stoichiometry of the reaction:

3 moles of lead nitrate are produces 3 moles of lead metal.

so, 0.0261 moles of lead nitrate will produce = of lead metal.

molar mass of lead = 207.2 g/mol

putting values in above equation, we get:

mass of lead = 5.408 grams

hence, the theoretical yield of solid lead comes out to be 5.408 grams.
