The mass number of aluminium hydroxide is 78 thus, the number of moles in 0.745 g is:
no. of moles= mass/ RFM
= 0.745/78
=0.00955moles
Therefore the 0.00955 moles should be in the 35.18 ml
therefore 1000ml of the solution will have:
(0.00955ml×1000ml)/35.18
=0.2715moles
The solution will be 0.27M hydrochloric acid
Answer:
A. Chemical because there alot of chemicals that contains energy such as Carbohydrates which fruit and vegetables contain.
Answer : The change in energy of an atom is, 
Solution : Given,
Wavelength of the photon = 
Formula used :
where,
E = energy of an atom
h = Planck’s constant = 
c = speed of light = 
= wavelength of photon
Now put all the given values in the above formula, we get the energy of an atom.
Therefore, the change in energy of an atom is,
