First calculate the Ar of the compound.. ( Ar of C6H12O6 is 180)
Then divide the At of the required element by 180 and multiply by 100...
so, for carbon 12 * 6 = 72 (THERE ARE 6 CARBON ATOM)
(72/180) * 100 =40%
ITS THE SAME FOR THE OTHER 2 ELEMENT
Breaking glass is an example of a physical change because if you break it, it is still glass.
Solution :
Time (sec) Volume of NaOH (mL)
339 26.23
1242 27.80
2745 29.70
4546 3.81
39.81
Now the example of the first order kinetics w.r.t volumetric analysis is :

Here, 

= volume at time 0 = 0
Since the interval is not constant, we take the time interval as


= 1402.3333
≈ 1402 seconds


= 0.001643 x 0.52045
= 0.00082

Therefore, the first order rate constant is k
.
Answer:
Option-D: 2.3 × 10⁻³ mol/dm³
Explanation:
Calculate moles of ascorbic acid,
Moles = Mass / M.Mass
Moles = 0.080 g / 176 g/mol
Moles = 0.00045 mole
Also,
Molarity = Moles / Vol. in dm³
Molarity = 0.00045 mol / 0.20 dm³
Molarity = 0.00227 mol.dm⁻¹ or 2.3 × 10⁻³ mol/dm³
Answer:
Solid
Explanation:
As the temperature continues to drop, the matter forms a solid. Due to the solid's low kinetic energy, particles have no "time" to move around, the particles have more "time" to be attracted. Therefore, solids have the strongest intramolecular forces (because they have the strongest attraction).
