Answer:
Concentration of ammonia = 3M
Explanation:
The reaction for the question is a neutralization reaction between HCl and NH₃
The chemical equation for the reaction is given as
HCl + NH₃ → NH₄CL
1 : 1 1
Volume of HCl = 18.1ml = 0.0181L
Volume of NH₃ = 5ml= 0.005L
Molar concentration of HCl=0.8M
Molar Concentration of NH₃ =?
Number of moles(n)= Molar concentration × Volume
n = C × V
n of HCL= 0.8 × 0.0181
n = 0.01448moles
Since mole ration for the reaction from the balanced equation above is 1:1,
n of NH₃ = 0.01448
molar concentration (C) of NH₃ = n/v
C of NH₃ = 0.01448/0.005
C of NH₃=2.896
C OF NH₃ =3M
A - 1. Carbon dioxide is converted to sugar used for food (this is process of phosynthesis).G - 2. Carbon trapped in fossil fuels is converted to carbon dioxide (this is combustion of fuel).E - 3. Organic carbon is converted to fossil fuels.H - 4. Carbon dioxide is converted to carbonates.F - 5. Sugar is broken down and converted to carbon dioxide (this is breathing).
CnH2n since the equivalent unsaturation is equal with 1
Answer:
Explanation:
Given that:
The energy of the photon = 2.3 eV
Energy in eV can be converted to energy in J as:
1 eV = 1.60 × 10⁻¹⁹ J
So, Energy = 
Considering
Where,
h is Plank's constant having value 
c is the speed of light having value 
is the wavelength of the light being bombarded
Thus,
Also,
1 m = 10⁻⁹ nm
So,
