Answer:

e. 3

Explanation:

In order to solve this problem we need to keep in mind the definition of pH:

pH = -log[H⁺]

As stated by the problem, the hydrogen ion concentration, [H⁺], is 1x10⁻³ M.

As all required information is available, we now can calculate the pH:

pH = -log(1x10⁻³ M)

pH = 3

The correct option is thus e.

Phosphoric acid h3po4 is an important industrial chemical used in fertilizers, detergents, and the food industry. it is produced

kenny6666 [7]

Answer:

1) P₄ + 5O₂ → P₄O₁₀ redox reaction

2) P₄O₁₀ + 6H₂O → 4H₃PO₄ acid-base reaction

3) Ca₅(PO₄)₃F + 5H₂SO₄ → 3H₃PO₄ + HF + 5CaSO₄ precipitation reaction

Explanation:

The reactions that take place in the electric furnace method are:

1) P₄ + 5O₂ → P₄O₁₀

This is a redox reaction, because the oxidation state of the reactants is changed.

2) P₄O₁₀ + 6H₂O → 4H₃PO₄

This is an acid-base reaction, because there's an exchange of H⁺ species.

The reaction that takes place in the wet process is:

3) Ca₅(PO₄)₃F + 5H₂SO₄ → 3H₃PO₄ + HF + 5CaSO₄

This is an precipitation reaction, because a precipitate (a solid phase in a liquid phase) is formed.

You put scruffy can run up to 2 meters/sec on his fastest days scruffy has a mass of 8 KG what is his maximum kinetic energy on

ale4655 [162]

Answer:

E = 16 J

Explanation:

We have,

You put scruffy can run up to 2 m/s on his fastest days scruffy has a mass of 8 kg

It is required to find the maximum kinetic energy on his fastest days. If v is the velocity, then kinetic energy is given by :

$E=\dfrac{1}{2}mv^2$

Plugging all the values,

$E=\dfrac{1}{2}\times 8\times 2^2 \\\\E=16\ J$

So, the maximum kinetic energy on his fastest day is 16 J.
