Answer:
4.85 x 10⁻¹⁹J
Explanation:
Given parameters:
Wavelength = 410.1nm
Unknown:
The energy of the violet light = ?
Solution:
The energy of a wave can be derived using the expression below;
E = 
h is the planck's constant
c is the speed of light
Insert the parameters and solve;
E = 
= 4.85 x 10⁻¹⁹J

26. 2
That would equal 54 kilograms of water. i know it sounds dumb but you have to realize that the weight will not just decrease since that's the units of measure were dealing with
1.Products of most combustion reactions are:
Carbon dioxide and water
2.Alloys are made by melting and combining metals together.
Chemical changes involve electrons,in this process no electron is used/shared or given.
Thus,its not a chemical change.
