Answer:
An aldehyde is a carbonyl group with a carbonyl carbon bonded to hydrogen and can be oxidized to a ketone while a ketone is a carbonyl group with a carbonyl carbon only bonded to oxygen atom and cannot be oxidized
Some of oxidizing agents are potassium dichromates, bradys reagent....
Answer:
2K + HgCl2 —> Hg + 2KCl
Explanation:
K + HgCl2 —> Hg + KCl
The above equation is not balanced
To balance the equation, do the following.
First, put 2 in front of KCl, the equation becomes,
K + HgCl2 —> Hg + 2KCl
Now we see that Cl is balanced but K is not. To balance K, put 2 in front of K as shown below:
2K + HgCl2 —> Hg + 2KCl
Now we can that the equation is balanced
Answer:
a. alkali
b. chemical
c. reactants
d. neutralised, acid
e. neutralisation
f. products
Explanation:
hope this helps and sorry if it is not right :)
E = hf
c = speed of electromagnetic wave, c ≈ 3 * 10⁸ m/s,
Planck's constant h = 6.63 *10⁻³⁴ Js
h = Planck's constnat, Frquency, f = c/λ = (3*10⁸)/(488*10⁻⁹)
E = hf
E = hc/λ
E = (6.63 * 10⁻³⁴ * 3 * 10⁸) /(488 * 10⁻⁹)
Energy, E ≈ 4.0758 * 10⁻¹⁹ Joules.
