Flourine I guess must be the answer
In order to calculate the molar mass of the protein, we may manipulate the ideal gas equation:
PV = nRT, where n is the number of moles. We also know that:
n = m / Mr, where m is mass and Mr is molecular weight
Thus,
Mr = (mRT)/(PV)
Here, the mass is in grams, the temperature is in Kelvin, the pressure is in atm and the volume is in liters, so the molar gas constant is 0.082057.
Mr = (3.6 * 0.082057 * (27 + 273)) / (0.0203 * 0.2)
Mr = 21,828 g/mol
Thus, the Mr of the protein is 2.18 x 10⁴ g/mol
Answer:
A. Atoms randomly crashing into each other
E. The force of one object pushing against the force of another object.
Explanation:
Forces can be classified into two categories based upon the the mode of transfer or application:
1. Contact forces
2. Non-contact forces
Contact forces are the ones which require the physical contact of the matter to get transferred and tend to create the affect. Whereas non-contact forces have the field property which transfers the affect of force from one point to another without any physical contact of the matter or the medium.
- Atoms crashing onto each other have some mass and velocity which upon collision impacts the other atoms exerts a contact force.
- The interaction between the charged particles due to their charges is always due to the electric field be it electron or proton, be it within an atom or out of an atom.
- The force between any two objects pushing or pulling each other is also possible only due to contact.
Answer:
The depth of the damage is given as 
Explanation:
From Fick's second law
![\frac{C_{x}-C_{0}}{C_{s}-C_{0}} = 1 -erf [\frac{x}{2\sqrt{Dt} } ] ...(1)](https://tex.z-dn.net/?f=%5Cfrac%7BC_%7Bx%7D-C_%7B0%7D%7D%7BC_%7Bs%7D-C_%7B0%7D%7D%20%3D%201%20-erf%20%5B%5Cfrac%7Bx%7D%7B2%5Csqrt%7BDt%7D%20%7D%20%5D%20...%281%29)
Where
is the temperature when the skin is damage
is the initial temperature of the skin
is the temperature of the oven
erf is a mathematical function known as error function
D is the thermal diffusivity
x is the depth of the damage
From the question we are given that
= 62°C
= 33°C
D = 
Substituting values into equation one
![\frac{62-33}{200-33} = 1 -erf [\frac{x}{2\sqrt{2.5*10^{-7}} *2} ]](https://tex.z-dn.net/?f=%5Cfrac%7B62-33%7D%7B200-33%7D%20%3D%201%20-erf%20%5B%5Cfrac%7Bx%7D%7B2%5Csqrt%7B2.5%2A10%5E%7B-7%7D%7D%20%2A2%7D%20%5D)
![erf[\frac{x}{1.414*10^{-3}} ] = 0.826\\](https://tex.z-dn.net/?f=erf%5B%5Cfrac%7Bx%7D%7B1.414%2A10%5E%7B-3%7D%7D%20%5D%20%3D%200.826%5C%5C)
Let assume that 
Hence
Looking at the table of error function shown on the first uploaded image
We can use interpolation to obtain the value of z in this manner
z = 0.96
Substituting the value of z into equation 2
One Ba2+ and two Br- ions will be there.
