I am rectifying the mains voltage which is 120V @ 5A with a full wave rectifier. How many volts and microfarads will my capacitor need to smooth out my rectified DC?

Are there any online calculators for this?

Thank you in advance!

Is potassium carbonate a strong base or weak base? Is phospheric acid strong acid or weak acid? What indicator should I use if I want to titrate potassium carbonate with phosphoric acid for complete neutralisation? Also, what pH does that indicator change at? Any alternative indicator? It would be good if you could provide a source.

Apart from pure bonding between the same elements eg O-O and N-N [both sets purely covalently bonded] is it possible to have two or more different element types bonded together that are purely ionic or purely covalently bonded? if not why? Is NaCl purely an ionic bond?

Again I stress - SPATIAL dimensions. Currently, physics considers reality as a matrix consisting of 3 dimensions of space and a 4th dimension of time. For this question, all dimensions involved are entirely spatial, not temporal. What technology do we have that might be able to touch upon such a concept? Any? Even just in theory?
