Chemical equations must be balanced.
... This equation is not balanced. There is one C on each side of the equation, so C is balanced. However, on the left side, H has a subscript of 4, which means there are four hydrogen atoms. On the right side, H has a subscript of 2, which means there are two hydrogen atoms. Also, there are two oxygen ...

... This problem requires a little bit more of analysis. Neutral atoms should have the same number of protons and electrons. Species W, X, and Z all have unequal numbers of protons and electrons. Specie Y is therefore the neutral atom. To determine the element, we know that the no. of protons is equival ...

The Heisenberg uncertainty principle states that it is fundamentally impossible to know precisely both the velocity and position of a particle at the same time. The only quantity that can be known is the p ...

Arrangement of Electrons in Atoms
... For a given metal, no electrons were emitted if the lights frequency was below a certain minimum. The brightness of a light won’t necessarily cause electrons to flow. Ex. Red light will not cause electrons to flow in a sheet of sodium metal, no matter how long or bright the source is. Violet light w ...
