Answer:
Energy of photon is 34.45 ×10⁻¹⁹ J.
Explanation:
Given data:
Frequency of photon = 5.2×10¹⁵ s⁻¹
Plancks constant = 6.626×10⁻³⁴ Js
Energy of photon = ?
Solution:
Formula:
E = h.f
by putting values,
E = 6.626×10⁻³⁴ Js × 5.2×10¹⁵ s⁻¹
E = 34.45 ×10⁻¹⁹ J
Thus, energy of photon is 34.45 ×10⁻¹⁹ J.
Answer:
A stir bar consists of a magnetic bar used to agitate a liquid mixture or solution
Explanation:
Plasmolysed because of osmosis as the salt solution has lower water potential than the cells of the stalk
Esters contains a double bond between carbon atom and oxygen atom while carboxylic acid lack double bond between carbon and oxygen atom.The lack of double bond in carboxylic acid make the force of interaction between carbon and oxygen strong and particles become tightly packed which make carboxylic acid solid. The presence of double bond in esters make the force of interaction weak thus they are liquid.
