In the reaction between Lithium Sulfate and an excess of Lead (II) Nitrate, how many molecules of Lithium Nitrate can be expecte
siniylev [52]

Answer:

1.46x10^{23}molecules \ LiNO_3

Explanation:

Hello,

In this case, the undergoing chemical reaction is:

Li_2SO_4 + Pb(NO_3)_2 \rightarrow PbSO_4+2LiNO_3

Thus, since lead (II) nitrate is in excess, we can directly compute the moles of lithium nitrate by applying the 1:2 molar ratio between them in the chemical reaction as well as the molar mass of Lithium Sulfate that is 110 g/mol for the stoichiometric shown below factor:

n_{LiNO_3}=13.3gLi_2SO_4*\frac{1molLi_2SO_4}{110gLi_2SO_4} *\frac{2molLiNO_3}{1molLi_2SO_4} =0.242molLiNO_3

Finally, by using the Avogadro's number we are able to compute the molecules:

0.242molLiNO_3*\frac{6.022x10^{23}molecules\ LiNO_3}{1mol}=1.46x10^{23}molecules \ LiNO_3

Best regards.

Eddi Din [679]

Answer:

La Nina

Explanation:

La Nina -

The word La Nina means " the little girl " , in spanish language .

La Nina , is an ocean - atmospheric process , which occurs in the eastern equatorial Pacific Ocean .

It is exactly opposite of El Nino , which means " the little boy " .

In the phase of La Nina , the temperature of the eastern equatorial Pacific Ocean becomes lower than the usual temperature by around 3°C to 5°C .

This phase of La Nina is for around 5 months in an year .

Hence , from the given statement of the question ,

The correct term is La Nina .
