The formula for rate is r= d t Solve for d

wlad13 [49]

Rate is ...

... r = d/t

Multiply both sides of the equation by time to find distance.

... rt = d

The equation for d is ...

... d = r·t

un refresco tiene una concentración de 3.8 x 10-4 de iones H+. determina el valor de PH de ese refresco

kifflom [539]

Answer:

El pH del refresco es 3.42.

Step-by-step explanation:

Se puede calcular el pH del refresco usando la siguiente fórmula:

$pH = -log([H^{+}])$

En donde:

[H⁺]: es la cocentración de los iones H⁺ de la solución

Entonces, el pH es:

$pH = -log([H^{+}]) = -log(3.8\cdot 10^{-4}) = 3.42$

El resutlado obtenido nos permite concluir que ese refresco es ácido.

Por lo tanto, el pH del refresco es 3.42.

Espero que te sea de utilidad!

A square base of a pyramid has the dimensions 5 yards by 5 yards. The height of one of the triangular faces is 12 yards. How can

-Dominant- [34]

Answer:

145 yards squared

Step-by-step explanation:

So the area of the base is area of a square with side length of 5 yards $5*5=25$

The area of one triangular face base times height divided by two and then simply multiplied by 4 because there are 4 triangular faces.

$(\frac{5*12}{2} )*4 = 120$

So the total surface area is $25+120=145$ yards squared
