Answer:
Joule
Electrical Energy: The Volt
Explanation:
As we now know that energy is the capacity to do work, with the standard unit used for energy (and work) being the Joule. A joule of energy is defined as the energy expended by one ampere at one volt, moving in one second.
Answer:158.2 J
Explanation: Use your equations and fill in
<span>Because copper (II) cations have a charge of +2 and phosphate anions have a charge of -3, the formula of anhydrous* copper (II) phosphate is
Cu3(PO4)2
This shows that each formula unit contains 2 atoms of phosphorus. Therefore, the atoms of phosphorus in 4.8 formula units is
4.8 x Avogadro's Number (</span><span>6.022x10*23)</span>, or about 2.9 X 10*24 atoms
Answer: Iron(III) oxide or ferric oxide, where the iron atom exhibits an oxidation state of +3. The chemical formula of this compound is Fe2O3.
