Answer: Option (C) is the correct answer.
Explanation:
A water molecule is made up of two hydrogen atoms and one oxygen atom. Its molecular formula is 
.
It is known that hydrogen is electropositive in nature whereas oxygen is electronegative in nature. Therefore, oxygen will pull the electron of hydrogen towards itself as a result, there will be formation of partial positive charge on hydrogen and partial negative charge on oxygen atom.
Thus, the water molecule becomes polar. So, we can conclude that water molecule is a polar molecule because water molecules have a positive charge on one end and a negative charge on the other.
Answer:
Carbon is the only element.
This separation technique is a 4-step procedure. First, add H₂SO₄ to the solution. Because of common ion effect, BaSO₄ will not react, only Mg(OH)₂.
Mg(OH)₂ + H₂SO₄ → MgSO₄ + 2 H₂O
The aqueous solution will now contain MgSO₄ and BaSO₄. Unlike BaSO₄, MgSO₄ is soluble in water. So, you filter out the solution. You can set aside the BaSO₄ on the filter paper. To retrieve Mg(OH)₂, add NaOH.
MgSO₄ + 2 NaOH = Mg(OH)₂ + Na₂SO₄
Na₂SO₄ is soluble in water, while Mg(OH)₂ is not. Filter this solution again. The Mg(OH)₂ is retrieved in solid form on the filter paper.
Answer:
the answer for this question is true
Answer: <em>Upper N upper H subscript 4 superscript plus. and Upper S upper O subscript 4 superscript 2 minus.</em>
Explanation: <em>The spectator ions in this reaction are the ammonium ion and the sulfate ions.
</em>
<em>
</em>
<em>In a reaction, not all of the ions are reacting. The ions not reacting are called the spectator ions.
</em>
<em>
</em>
<em>When we eliminate such ions, we get an overall view of the reaction.
</em>
<em>
</em>
<em> The reaction is:
</em>
<em>
</em>
<em> 2NH₄⁺ + 2OH⁻ + 2H⁺ + SO₄²⁻ ⇒ 2NH₄⁺ + 2H₂O + SO₄²⁻
</em>
<em>
</em>
<em>In ionic equations, water soluble reactants and products are split into their constituent ions while non-ionizing or gaseous reactants and products are represented as formulae or molecules.
</em>
<em>
</em>
<em> The species that are not reacting and appears on both sides are 2NH₄⁺ and SO₄²⁻ and are the spectator ions.
</em>
<em>
</em>
<em>These non-reactive species are eliminated from the overall ionic equation that shows the reacting ions only.</em>
