Well cars need gas to run on if the car does not have gas it wont run and you cant get to places you need to go only if you have gas.
Answer:
453 or 453.592
Explanation:
400 jellybeans are about a pound and a pound is 453.592 grams
Answer:
Low-energy reactants become high-energy products.
Explanation:
In electrolysis, you are forcing a reaction to occur that otherwise wouldn't happen.
You are pumping energy into the system and converting low-energy reactants into high-energy products.
B is wrong. Nature tends to run downhill energetically, so high-energy reactants tend to form low-energy products spontaneously.
C and D are wrong. If an element is unreactive, it stays unreactive, and vice versa. You can't change the nature of an element.
Atmospheric
pressure<span>, sometimes also called barometric pressure, is the pressure exerted by the weight of air in
the </span>atmosphere of Earth<span> (or that of another planet)</span>
1 atm is equivalent to = 101325
Pa
= 760 mmHg
= 760 torr
= 1.01325 bar
So 1.23 atm is equal to
= 124629.8 Pa
= 934.8 mmHg
= 934.8 torr
<span>= 1.2462 bar</span>
Answer:
OH−(aq), and H+(aq)
Explanation:
Redox reactions may occur in acidic or basic environments. Usually, if a reaction occurs in an acidic environment, hydrogen ions are shown as being part of the reaction system. For instance, in the reduction of the permanganate ion;
MnO4^-(aq) + 8H^+(aq) +5e-------> Mn^2+(aq) + 4H2O(l)
The appearance of hydrogen ion in the reaction equation implies that the process takes place under acidic reaction conditions.
For reactions that take place under basic conditions, the hydroxide ion is part of the reaction equation.
Hence hydrogen ion and hydroxide ion are included in redox reaction half equations depending on the conditions of the reaction whether acidic or basic.
