Yes it is possible because, olymorphismis when two or more crystal structures are possible for a material of given composition. Isomerismis when two or more polymer molecules or repeat units have the same composition, but different atomic arrangements.
Answer:
32 mL
Explanation:
<em>A chemist must prepare 500.0mL of hydrobromic acid solution with a pH of 0.50 at 25°C. He will do this in three steps: Fill a 500.0mL volumetric flask about halfway with distilled water. Measure out a small volume of concentrated (5.0M) stock hydrobromic acid solution and add it to the flask. Fill the flask to the mark with distilled water. Calculate the volume of concentrated hydrobromic acid that the chemist must measure out in the second step. Round your answer to 2 significant digits.</em>

Step 1: Calculate [H⁺] of the dilute solution
pH = -log [H⁺]
[H⁺] = antilog -pH = antilog -0.50 = 0.32 M
Step 2: Calculate [HBr] of the dilute solution
HBr is a strong acid that dissociates according to the following equation.
HBr ⇒ H⁺ + Br⁻
The molar ratio of HBr to H⁺ is 1:1. The concentration of HBr is 1/1 × 0.32 M = 0.32 M.
Step 3: Calculate the volume of the concentrated HBr solution
We will use the dilution rule.
C₁ × V₁ = C₂ × V₂
V₁ = C₂ × V₂ / C₁
V₁ = 0.32 M × 500.0 mL / 5.0 M
V₁ = 32 mL
Answer:
It has 3 significant figures
Explanation:
Numbers after decimal are significant figures and zero before decimal is not a significant number.
Hence significant figures are 1,1&5
Answer: Fusion is a type of nuclear reaction.
Explanation:
Nuclear reaction is defined as those reaction in which nucleus of an atom is involved. There are two types of nuclear reaction:
- Fusion : In this type, two or more smaller atomic nuclei are combined together to form larger nucleus with release in energy
- Fission : In this type, one large unstable nucleus breaks down into two smaller nuclei with release in energy.
