Answer:
The oxidation state of carbon in CaC204 is 3
Answer: I believe the answer is A - the total growth of the plants.
Explanation: The total growth of the plants depends on the hours of sunlight. So, this would be your dependent variable, while the hours (amount) of sunlight would be your independent variable.
Esters are compounds that form when the organic acids react with alcohols. The answer would be B.
Henlo!
Bohr's model was unable to calculate or it required precise information about position of an electron and its velocity. It is very difficult to calculate velocity and position of an electron at the same time because electron i too small to see and may only be observed if peturbed, for example we could hit the electron with another particle such as photon or an electron, or we could apply electric or magnetic field to the electron. This will inevitably change the position of the elctron or its velocity and direction. Heisenberg aid that more precisely we can define the position of an electron, the less certainity we are able to define its velocity and vice versa.
In short, first option is correct one
