What is the voltage of a battery that uses 800j of energy to move 40c of charge through a resistor

So this can be done simply by using the units of Volts volts can be broken down to joules per coulomb (I can’t spell) so just take the energy and divide by amount of charge and you get the voltage, so 800J/40C will give you 20 Volts

The best description is: . nobody has any idea what q is.

Molybdeum(mo)orruthenium (ru)actually, elements with similar chemical properties as technetium would bemn, re, and bh. this is because elements in the same group/family (column) have similar chemical properties. elements in the same period (row) have the same number of energy levels (or shells).
