Igneous that can be changed by heat and pressure which can change the form of the rock
I believe doctors use (3) Co-60 to treat ILWs. Uranium and Carbon are not used, and a different isotope of lead is used to be attached to monoclonal antibodies.
I want to say 8 but i'm not sure. I just did a lesson on this and my notes say it could be 8 but then again I'm not sure.
Answer:
A system is in equilibrium when the rate of the forward reaction is equal to the rate of the reverse reaction.
Explanation:
In a system in equilibrium, the rupture and formation of new bonds from the formation and decomposition of substances must have the same reaction rate. Thanks to equal speeds we can say that a system in equilibrium is dynamic and in general every system tends to move spontaneously towards equilibrium. The environment never interferes.
For example.
N2 (g) + 3H2 (g) ---> 2NH3 (g) formation
2NH3 ----> N2 (g) + 3H2 (g) decomposition
N2 (g) + 3H2 (g) <------> 2NH3 (g) In equilibrium
