Answer:
El pH del refresco es 3.42.
Step-by-step explanation:
Se puede calcular el pH del refresco usando la siguiente fórmula:
![pH = -log([H^{+}])](https://tex.z-dn.net/?f=pH%20%3D%20-log%28%5BH%5E%7B%2B%7D%5D%29)
En donde:
[H⁺]: es la cocentración de los iones H⁺ de la solución
Entonces, el pH es:
![pH = -log([H^{+}]) = -log(3.8\cdot 10^{-4}) = 3.42](https://tex.z-dn.net/?f=pH%20%3D%20-log%28%5BH%5E%7B%2B%7D%5D%29%20%3D%20-log%283.8%5Ccdot%2010%5E%7B-4%7D%29%20%3D%203.42)
El resutlado obtenido nos permite concluir que ese refresco es ácido.
Por lo tanto, el pH del refresco es 3.42.

Answer:
5×10⁻²
Step-by-step explanation:
- Move the decimal so there is one non-zero digit to the left of the decimal point.
- The number of decimal places you move will be the exponent on the 10. a. If the decimal is being moved to the right, the exponent will be negative.
b. If the decimal is being moved to the left, the exponent will be positive.
- Therefore. The answer is 5×10⁻²
Lets say for arguments sake that the bag contained 2 blue and 3 red marbles
p:q = 2:3 In order to get a ratio of 2:1 we would have to add 4 blue marbles
(6:3 = 2:1).
So the ratio p to r = 2:4 = 1:2 answer.
