You made hypochlorous acid (HOCI) by mixing bleach (NaOCI) with:
Annette [7]

<u>Answer:</u> When bleach is mixed with water, it produces hypochlorous acid.

<u>Explanation:</u>

The chemical name for bleach is sodium hypochlorite. When this compound is reacted with water, it produces hypochlorous acid and sodium hydroxide.

The chemical equation for the reaction of sodium hypochlorite and water follows:

NaOCl+H_2O\rightarrow HOCl+NaOH

By Stoichiometry of the reaction:

1 mole of sodium hypochlorite reacts with 1 mole of water to produce 1 mole of hypochlorous acid and 1 mole of sodium hydroxide.

Hence, when bleach is mixed with water, it produces hypochlorous acid.

A concentrated salt solution has a mass of 5.34 g for a 5.00 ml sample. what is the specific gravity of this solution?
Nutka1998 [239]

The specific gravity of the solution is 1.07, which contains 5.34g for a 5.00ml sample.

Density of a substance is

Density = Mass / Volume

             = 5.34/5

             = 1.07

Density of water = 1

Specific gravity = Density of substance/density of solvent

Specific gravity = 1.07 / 1

Specific gravity = 1.07

Specific gravity, often known as relative density, is the ratio of a substance's density to that of an industry standard.

If a material has a relative density that is less than 1 compared to the reference, it is less dense than the reference; if it is larger than 1, it is denser. Identical volumes of the two substances have the same mass if the relative densities are equal, or exactly 1.

What is the energy of a TV wave that NBC broadcasts, if it has a wavelength of 32 meters?
serg [7]

Answer:

Explanation:

E = hc/λ

h = planck's constant = 6.66 x 10 ^ -34

c = speed of light = 2.98 *10^8 m/s

E = (6.66 x 10 ^ -34 )(2.98 *10^8)/32

  = 19.85 * 10 ^-26

   =0.62 x 10^-26

   = 6.2 x 10^-27 J
