Answer:
The theoretical yield of the hydrogen sulfide is 68.0 grams.
Explanation:
Moles of aluminum sulfide = 4.0 mol
Moles of water = 4.0 mol
According to reaction, 6 moles of water reacts with 1 mole of aluminum sulfide,then 4 moles of water will react with :
of aluminum sulfide
1.5 moles aluminum sulfide < 4 moles aluminum sulfide
This means that water is present in limiting amount and aluminum sulfide is in excess amount.So, amount of hydrogen sulfide will depend upon moles of water.
According to reaction, 6 moles of water gives with 3 mole of hydrogen sulfide,then 4 moles of water will give :
of hydrogen sulfide
Mass of hydrogen sulfide:
2.0 mol × 34 g/mol = 68.0 g
The theoretical yield of the hydrogen sulfide is 68.0 grams.
Change in their environment
Answer: Elements in the same column are similar in their properties
Explanation: The columns on the periodic table are also know as group of the periodic table elements in the same group of the periodic table tends to have similar chemical properties because they all have the same number of valence electrons in their outermost shell. This plays an important roles in their reactivity and properties
Answer:
When a solution is heated, the solvent evaporates, leaving behind the dissolved solids as residue. When a solution containing dissolved solutes is heated, the solvent will evaporate. Only the solute will remain in the evaporating dish.

The name of the acid is Bromous acid and the Formula of the acid is HBrO₂.
<h3>What is Acids ? </h3>
Acids is defined as substances that is able to donate a proton or hydrogen ion to other substance. Acids acts as proton donor.
<h3>What is Oxoacids ? </h3>
An oxoacids is an acids that contains oxygen. It is also called oxyacids or ternary acids. Oxoacids are the acids of oxoanions.
If anion name contains the suffix ‘ate’ then replace ‘ate’ with ‘ic’.
If anion name contains the suffix ‘ite’ then replace ‘ite’ with ‘ous’.
Given anion is bromite. Formula of bromite is BrO₂⁻. It is an oxoanion.
Now write the name of acid. Here anion name contains the suffix ite so replace the ‘ite’ of bromite with ‘ous’.
The name of the acid is Bromous acid.
Formula of the acid is HBrO₂.
Thus from the above conclusion we can say that The name of the acid is Bromous acid and the Formula of the acid is HBrO₂.
