Answer:
The salt is barium chloride.
Explanation:

Moles of barium sulfate =
According to reaction, 1 mol of barium sulfate is produced from 1 mol of
.
Then 0.0480 moles will be produced from:
of
.
Mass of
used = 10.00 g
Moles of
=\frac{10.00 g}{\text{Molar mass}}[/tex]

Molar mass of
= 208.33 g/mol
The nearest answer to our answer is
.
The correct answer barium chloride with molar mass of 208.2 g/mol.
<u>Answer:</u> The lewis dot structure is attached below.
<u>Explanation:</u>
A Lewis dot structure is defined as the representation of atoms having electrons around the atom where electrons are represented as dots.
A ketene is an organic compound having general formula R′R″C=C=O, where R and R' are two different/same monovalent chemical groups.
The given chemical compound having formula
is represented as
.
Total number of unshared electrons = 4 (left on oxygen atom only)
The lewis dot structure of
is given in the image below.
