The periodic table is based on an element's

1 answer:

3 0

Well, TECHNICALLY, the periodic table is "based" upon a whole myriad of characteristics. But if you're talking about the consecutive arrangement of elements...it would be B, the atomic number.

Answer:

POLAR BONDS will form.

A polar bond is a covalent bond between two atoms where the electrons forming the bond are unequally distributed. This causes the molecule to have a slight electrical dipole moment where one end is slightly positive and the other is slightly negative.

What is the empirical formula for<br> P2S3 ?

tatiyna

Answer : The empirical formula is $P_2S_3$ .

Explanation :

Molecular formula : It is represented by the actual number of the atoms of all the elements present in a compound.

Empirical formula : It is represented by the simplest whole number of the atoms of all the elements present in a compound.

The given molecular formula is $P_2S_3$ .

For determining the empirical formula, we need to determine the valency which is divided by each element to get the empirical formula.

In the given formula, the valence is 1.

So, the empirical formula is $P_2S_3$ .

Answer 1: The correct answer is option (B)

Answer 2: The correct answer is option (B)

Explanation 1:

$2Na+Cl_2\rightarrow 2NaCl$

moles of NaCl = $\frac{\text{given mass of NaCl}}{\text{molar mass of NaCl}}=\frac{200 g}{58.5 g/mol}=3.4188 mol$

According to reaction, 2 moles NaCl are obtained from 2 moles of Na, then 3.4188 moles of NaCl are obtained from: $\frac{1}{1}\times 3.4188$ moles of Na.

Mass of Na = moles of sodium × Molar mass of sodium

$=23 g/mol\times 3.4188 mol=78.632 g$

From the given option nearest answer to calculated answer is option (B) that is 78.65 g.

Explanation 2:

$2K+2H_2O\rightarrow 2KOH+H_2$

moles of potassium(K)= $\frac{\text{given mass of K}}{\text{molar mass of K}}=\frac{23.5 g}{39 g/mol}=0.6025 mol$

According to reaction, 2 moles of K gives 2 moles of KOH , then 0.6025 moles of K will give : $\frac{1}{1}\times 0.6025 moles$ of KOH

Mass of KOH = moles of KOH × Molar mass of KOH

$0.6025 mol\times 56 g/mol=33.74 g\approx 33.7 g$

From the given option nearest answer to calculated answer is option (A) that 33.7 g.
