Ozone as a disinfectant as opposed to chlorine because in contrast to chlorine, ozone leaves no dangerous through-merchandise within the water or the surroundings.

Ozone quick reverts once more to pure oxygen if unused. Ozone is one of the strongest and fastest commercially available disinfectant and oxidant for water remedy, purifying water faster than chlorine.

Ozone is a specially reactive fuel composed of 3 oxygen atoms. it's far each a natural and a person-made product that takes location in the Earth's pinnacle environment and lower surroundings. relying on wherein it is inside the environment, ozone influences existence in the world in each proper or terrible methods. The ozone layer protects the Earth toward maximum UVB coming from the solar.

Disinfectants is any substance or device this is used typically on non-dwelling items to kill germs, including viruses, bacteria, and different microorganisms that could motive contamination and illness. Disinfectants are antimicrobial shops that are implemented to the floor of non-residing devices to ruin microorganisms that are residing at the items.

What does polar and non polar mean?

Arisa [49]

Polar is the separation of electric charge leading to a molecule or its chemical groups having an electric dipole or multipole moment.

Non-polar is one in which the electrons are distributed more symmetrically and thus does not have an abundance of charges at the opposite sides.

Calculate the standard entropy of reaction at 298 K for the reaction Hg(liq) + Cl2(g) → HgCl2(s) The standard molar entropies of

never [62]

Answer:

−153.1 J / (K mol)

Explanation:

Calculate the standard entropy of reaction at 298 K for the reaction Hg(liq) + Cl2(g) → HgCl2(s) The standard molar entropies of the species at that temperature are: Sºm (Hg,liq) = 76.02 J / (K mol) ; Sºm (Cl2,g) = 223.07 J / (K mol) ; Sºm (HgCl2,s) = 146.0 J / (K mol)

Hg(liq) + Cl2(g) → HgCl2(s)

Given that;

The standard molar entropies of the species at that temperature are:

Sºm (Hg,liq) = 76.02 J / (K mol) ;

Sºm (Cl2,g) = 223.07 J / (K mol) ;

Sºm (HgCl2,s) = 146.0 J / (K mol)

The standard molar entropies of reaction = Sºm[products] - Sºm [ reactants]

= 146.0 J / (K mol) – [76.02 J / (K mol) +223.07 J / (K mol) ]

= -153.09 J / (K mol)

= or -153.1 J / (K mol)

Hence the answer is −153.1 J / (K mol)

How are crystals made?

Step2247 [10]

Explanation:

Crystals often form in nature when liquids cool and start to harden. Certain molecules in the liquid gather together as they attempt to become stable. They do this in a uniform and repeating pattern that forms the crystal. In nature, crystals can form when liquid rock, called magma, cools.

hoa [83]

the reagents necessary to convert alcohol to ketone $Na_2Cr_2O_7 , H_2O$ which involves oxidation of alcohols.

<h3>What is oxidation of alcohols?</h3>

Alcohol oxidation is a significant organic chemistry process. Secondary alcohols can be oxidized to produce ketones, while primary alcohols can be oxidized to produce aldehydes and carboxylic acids.
In contrast, tertiary alcohols cannot be oxidized without the C-C bonds in the molecule being broken.
In order to cause primary alcohols to oxidize into aldehydes
