Your answer is sooo close!!! But I think it is precisely about the same. :)
4AI(s) + 302(g) = 2 AI203(s)
Explanation:
Ch4+heat=CO2.
Ans
It is not balanced equation if you want it say in comment
<span>When a sound wave reaches near the ear, the outer part of the ear acts like if its a funnel, so it catches the wave and funnels it into the ear. They the wave hits the eardrum. Then the bones in the eardrum cause each other to vibrate. Then they are sensed by nerves and sends signals to the brain to interpret sound. Hope This Helps!</span>
Answer:
The answer to your question is below
Explanation:
Data
pOH = 5.9
a) [OH⁻] = ?
pOH measures the [OH⁻]
Formula
pOH = -log[OH⁻]
-Substitution
5.9 = -log[OH⁻]
[OH⁻] = antilog (-5.9)
-Result
[OH⁻] = 1.26 x 10⁻⁶ M
b) [H₃O⁺]
pH + pOH = 14
-Solve for pH
pH = 14 - pOH
-Substitution
pH = 14 - 5.9
-Result
pH = 8.1
-Calculate [H₃O⁺]
pH = -log[H₃O⁺]
-Substitution
8.1 = -log[H₃O⁺]
[H₃O⁺] = antilog(-8.1)
-Result
[H₃O⁺] = 7.9 x 10⁻⁹ M
c) This solution is alkaline because the pH is higher than 7.
They are all examples of chemical formulas
