Answer:

The answer to your question is t = 50 s

Explanation:

Data

Function

H(t) = -t² + 100t + 100

Process

1.- Find the derivative of the function to get the maximum

H'(t) = -2t + 100

2.- Equal to zero the derivative

          -2t + 100 = 0

3.- Solve for t

          -2t = -100

             t = -100/-2

             t = 50 s

4.- Conclusion

It takes 50 s to reach the maximum height

How do the results for methane compare to those for butane? does your experimental data verify charles's law?
maks197457 [2]
<span>Yes, it does. Charlie's law states that when the volume is constant the mass of a gas will be directly related to the temperature. When the temperature and pressure were fixed in both gases the relation between the temperature and the volume increased, so the volume increased when the temperature increased.</span>

Write a chemical equation showing how this is an acid according to the Arrhenius definition. Express your answer as a balanced c
mylen [45]

Answer:

HC_2H_3O_2_{(aq)}\rightarrow H^+_{(aq)}+C_2H_3O_2^-_{(aq)}

Explanation:

Arrhenius theory:-

The Arrhenius theory was introduced introduced by Swedish scientist named Svante Arrhenius in 1887.

According to the theory, acids are the substances which dissociate in the aqueous medium to produce electrically charged atoms ( may be molecule). Out of these species furnished, one must be a proton or the hydrogen ion, H^+.

So,

The expression for acid, HC_2H_3O_2 is:-

HC_2H_3O_2_{(aq)}\rightarrow H^+_{(aq)}+C_2H_3O_2^-_{(aq)}
