The pressure of water created in a service station is due to pumping. <span>Pumps operate by some mechanism (typically </span>reciprocating<span> or </span>rotary<span>), and consume </span>energy<span> to perform </span>mechanical work<span> by moving the fluid. Hope this helps. Have a nice day.</span>
Zero ( If the number of electrons equal of the protons in an atom.
Explanation:
➢number of moles. Moles and Chemical Reactions. Chapter 4. 3 H2. + N2. →. 2 NH3 ... How many grams of NH3 would form if 2.11 moles of N2 reacted with ...
The answer is 2 because if he is going at 12mph that he is going 6mph in 30min. So 8-6=2
