<h2>Answer:</h2>
Given data:
Volume of solution: 500 ml
Mass of 10 ml solution: 10.7 g
Density of whole solution: ?
<h3>Solution:</h3>
Mass of 500 ml solution : 10.7/10 * 500 = 535 g
Density = Mass/ volume
<u>Putting values in formula :</u>
D = 535/500 = 1.07 g/ml
Hence Density = 1.07 g/ml
Answer:
Single-Replacement Reaction
General Formulas and Concepts:
<u>Chemistry - Reactions</u>
- Synthesis Reactions: A + B → AB
- Decomposition Reactions: AB → A + B
- Single-Replacement Reactions: A + BC → AB + C
- Double-Replacement Reactions: AB + CD → AD + BC
Explanation:
<u>Step 1: Define RxN</u>
Mg + H₂SO₄ → MgSO₄ + H₂
<u>Step 2: Identify RxN</u>
Mg + H₂SO₄ → MgSO₄ + H₂
Single-Replacement Reaction A + BC → AB + C
- A = Mg
- BC = H₂SO₄
- AB = MgSO₄
- C = H₂
From the gas law, PV=nRT we can say that P(pressure), V(volume) and T (temperature) are related to each other. The initial volume of sample is 408 ml
Given that initial volume of the sample = V1
initial pressure of the sample = 0.92atm
initial temperature of the sample = 23.2oC
Final pressure of the sample = 1.3atm
Final temperature of the sample = 40.1 oC
Final volume of the sample = 500ml = 0.5L
Using the relation P1V1/T1 = P2V2/T2
V1 = 1.3x0.5x23.2/40.1x0.92 = 15.08/36.892 = 0.408
Hence the initial volume of sample = 408 ml

<span>Na (sodium) is highly electropositive. Its has 1 electron in its outermost orbit which is transferred to an electronegative atom to form an ionic bond.
It only needs to get rid of one valence electron to take part in a reaction. That's how it's highly reactive.</span>
<span>If two metals both have the same color, have similar densities, and are about the same size, but one is shiny and the other is dull, they can be separated based on the lustrous physical property of a metal. Lustrous is the property of the metal to shine/gleam gently because of its particle arrangement of atoms. </span>
