Answer:
False
Explanation:
Chemical reaction equation:
C₅H₁₂ + 8O₂ → 2CO₂ + 6H₂O
Most chemical reactions obey the law of conservation of mass. By so doing, the number of chemical elements on both sides of the expression must be balanced.
Reactants Products
C 5 4
H 12 12
O 16 10
We see that for C and O, the number of atoms on both sides of the expression differs and so, it is not balanced.
Hi There!
Black powder is an explosive powder consisting of saltpeter, sulfur, and charcoal, used chiefly in old guns fired for sport, in fireworks, and for spotting charges in practice bombs; black gunpowder.
In addition to being easily ignited by friction and impact, black powder is also extremely sensitive to flame and spark. It ignites violently when unconstrained and explodes when lit in even the slightest amount of confinement.
Thank you,
Eddie
Explanation:
The pH of a substance can be found by using the formula
![pH = - log[ H^{ + } ]](https://tex.z-dn.net/?f=pH%20%3D%20%20-%20%20log%5B%20H%5E%7B%20%2B%20%7D%20%20%5D)
where [ H+ ] is the hydrogen ion concentration in the substance
From the question
[ H+ ] = 2.1 × 10-¹² M
To find the pH substitute the value into the above formula
We have
We have the answer as
<h2>pH = 11.7 </h2>
The solution is basic since it lies in the basic region that is from 8 to 14
Hope this helps you
