Answer : The number of molecules of A needed to make 5000 molecules of AB will be, 5000
Explanation :
Law of conservation of mass : It states that mass can neither be created nor be destroyed but it can only be transformed from one form to another form.
The given balanced chemical reaction is,
As per question, molecule B is an excess reagent because it had enough molecule to make 5000 molecules of AB. So, molecule A is limiting reagent.
From the balanced reaction, we conclude that
As, 1 molecule of AB produced from 1 molecule of A
So, 5000 molecule of AB produced from 5000 molecule of A
Hence, the number of molecules of A needed to make 5000 molecules of AB will be, 5000
Answer: Force per unit area. Explanation: P = 25/20. P = 5/4 Pascal or 1.25 Pascal
Explanation: is this what you were looking for
To solve this problem it is necessary to express the term of the wavelength of continuous x-rays according to the Planck constant, the speed of light, the charge of the electron and the voltage. This definition is expressed mathematically as
Here,
h is Planck's constant
c is speed of light
e is charge of electron
V is the potential to which the electrons are accelerated.
From this definition we can see that the wavelength is independent of the mass of the target material. Therefore the wavelength will remain the same.
