Answer:
4.2 m
Explanation:
The energy (E) of the selector region of the spectrometer is:
E = v*B (equation 1)
Where v is the velocity, and B the magnetic field.
The force with which particle forms a curved path can be calculated by:
Where r is the radius of the particle, m is the mass, and q the electric charge. So:
For equation 1: v = E/B, so:
The two species will be separated by Δr = 0.42 mm
Δr = Δm*E/(q*B*B')
E/(q*B*B') = r/m
Δr = Δm*r/m
r = m*Δr/Δm
r is the large of curvature, m is the avarege mass = (28.0106 + 28.0134)/2 = 28.012:
r = (28.012*0.42)/(28.0134 - 28.0106)
r = 11.76504/(0.0028)
r = 4201.8 mm
r = 4.2 m
To balance a chemical equation, you want the same amount of elements to equal the same on both sides.
Step1. Write equation out
[CH4 + Cl2 ---> CCl4 + HCl]
C:1; H:4; Cl:2 C:1; H:1; CL:5 /// Cl = 5 since 4Cl + 1Cl
The Carbon element is balanced, but Hydrogen isn't.
So to balance it we will add a coefficient behind HCl, so now
[CH4 + Cl2 ------> CCl4 + 4HCL]
C:1; H:4; Cl:2 C:1; H:4; CL:8 ///// Carbon and hydrogen are balanced, but now Chlorine is not. Now we balance that element by addind a coefficiant behind CL2////
[CH4 + 4Cl2 -----> CCl4 + 4HCl]
C:1; H:4; Cl:8 C:1; H:4; CL:8 ///// So now that we added a 4*Cl2, it equals to Cl:8. So now what most people want to see is if every element is at its lowest balance, so we see if we can any coefficient lower. Just like simplifying if possible.
False. Raw water is water found in the environment that has not been treated and does not have any of its minerals, ions, particles, bacteria, or parasites removed. Raw water includes rainwater, ground water, water from infiltration wells, and water from bodies like lakes and rivers.
Answer:
A reversible Reaction is a reaction that takes place in the (Reactants)
If the reaction Were to (Equal), the rate of the forward reaction would equal that of the reverse reaction
