Hey there!
The correct answer to your question is option A.
The result of adding more solute to a solution is the boiling point increases.
Another name of the boiling point increasing is "Boiling point elevation".
The reason why solute increases the boiling point is because when the solute is added to the water, the energy increases.
Hope this helps you.
Have a great day!
It’s obvious that it’s 13 because 89 - 92 =13
What exactly is the project about ?????
Answer:
Molar mass = 27.88 g/mol
Explanation:
The relationship between how gases effuses is given by Graham's law of effusion. This law is given as;
Rg / Rxe = (Mxe / Mg)
Where;
Rg = Rate of effusion of gas g
RXe = Rate of effusion of Xe
Mxe = Molar mass of Xe = 131.29 g/mol
Mg = Molar mass of gas g
From the question;
Rg : Rxe = 2.17 : 1
Rg / Rxe = 2.17 / 1 = 2.17
2.17 = 131.29 / Mg
Squaring both sides
4.7089 = 131.29 / Mg
Mg = 131.29 / 4.7089
Mg = 27.88 g/mol
<h3>1. what is a typical characteristic of an ionic compound?</h3><h3>Answer:</h3>
Option-D : The ionic compound has a high melting point.
<h3>Explanation:</h3>
Ionic compounds are made up of positive ions called cations and negative ions called as anions. Cations are formed when an atom or group of atoms looses one or more electrons while, anion is formed when an atom or group of atoms gains electrons.
The two opposite ions formed interact through electrostatic interactions and form one of the strongest intramolecular bonding called ionic bonding. It requires very high energy to separate these ions from each other in solid form.
Examples: Melting Point of NaCl = 801 °C
Melting Point of MgCl₂ = 714 °C
Melting Point of CaCO₃ = 825 °C

<h3>2. what is shown by the structural formula of a molecule?</h3><h3>Answer:</h3>
Option-A : The arrangement of bonded atoms.
<h3>Explanation:</h3>
Structural formula is the graphical representation of of a chemical formula in either two dimensional or three dimensional space. It helps in depicting the arrangement of atoms or group of atoms in a compound or molecule.
Examples:
Below the attached figure shows the structural formula of Glucose with Chemical formula C₆H₁₂O₆, Sulfuric Acid with Chemical formula H₂SO₄ and Water with Chemical formula H₂O respectively.
