<span>The
energy that was produced is called, heat combustion. It is an energy released
in the form of heat when chemicals are mixed. An explosion of light and sound
are the common characteristics of heat combustion. The chemical reaction takes
place because of the presence of oxygen and hydrocarbon or organic molecule
substances that when mixed form carbon dioxide and water which then releases
heat and explosive characteristics.</span>

Answer:
What are the correct coefficients when this chemical equation is
balanced? *
P4 + 02 P2O5
<h2>1, 5, 2</h2>
Explanation:
For this reaction we have a combination reaction. Balancing Strategies: This combination reaction is a lot easier to balance and if you can get an even number of oxygen atoms on the reactants side of the equation.
Answer:
Hello there!
The first answer is hot
The second answer is sunshine!
Explanation:
Those make the most sense
Have a great day!
According to this formula:
(P1V1) / T1 = (P2V2) / T2
convert T from C° to Kelvin:
T1 = 83 + 273 = 356 K
T2= 96 + 273 = 369 K
convert P from torr to atm:
1 torr = 0.00131578947 atm<span>
p1 = 0.839474 atm
P2 = 1.415789 atm
By substitution in the previous formula:
(0.839474 x 10.6 ) / (356) = ( 1.415789 x V2 ) / 369
So:
V2 = 6.5 L</span>
