Answer: Option (a) is the correct answer.

Explanation:

A lithium atom has atomic number 3 and its electronic distribution is 2, 1. Therefore, it easily loses one electron and results in the formation of $Li^{+}$ which is known as lithium ion.

Whereas a nitrate ion has a chemical formula as $NO^{-}_{3}$ .

Since, charge on both lithium and nitrate ion is same in number. Therefore, when both these ions combine together then it results in the formation of $LiNO_{3}$ compound.

Name of this compound is lithium nitrate.

Thus, we can conclude that when a lithium ion and nitrate ion combine, the result is $LiNO_{3}$ .

Answer:

$P_4_{(I)}+5O_2_{(g)}+6H_2O_{(l)}\rightarrow +4H_3PO_4_{(l)}$

Explanation:

The first step is:

$P_4_{(I)}+5O_2_{(g)}\rightarrow 2P_2O_5_{(g)}$

Second step is:

$P_2O_5_{(g)}+3H_2O_{(l)}\rightarrow 2H_3PO_4_{(l)}$

Multiplying second step by 2, and adding both the steps, we get that:

$P_4_{(I)}+5O_2_{(g)}+2P_2O_5_{(g)}+6H_2O_{(l)}\rightarrow 2P_2O_5_{(g)}+4H_3PO_4_{(l)}$

Cancelling common species, we get that:

$P_4_{(l)}+5O_2_{(g)}+6H_2O_{(l)}\rightarrow +4H_3PO_4_{(l)}$

Gelneren [198K]

Answer:

The substance that remained on the filter paper is Al(OH).

Explanation:

Filter paper is the substance that is used in laboratory to separate the solid objects. It doesn't filter aqueous and gaseous products.
So in our experiment the product formed is aluminum hydroxide Al(OH) and sodium chloride (NaCl).
Between two products, sodium chloride is in aqueous form as indicated in the question. So it wont remain in the filter paper.

Hence aluminum hydroxide being only solid product remains on the filter paper.
