<h2>ANSWER:</h2><h3>LEWIS STRUCTURE:</h3>

Lewis structures, also called electron-dot structures are diagrams that show the bonding between atoms of a molecule, and the lone pairs of electrons that may exist in the molecule. A Lewis structure can be drawn for any covalently-bonded molecule, as well as coordination compounds.

iris [78.8K]

Answer:

10 kg of ice will require more energy than the released when 1 kg of water is frozen because the heat of phase transition increases as the mass increases.

Explanation:

Hello!

In this case, since the melting phase transition occurs when the solid goes to liquid and the freezing one when the liquid goes to solid, we can infer that melting is a process which requires energy to separate the molecules and freezing is a process that releases energy to gather the molecules.

Moreover, since the required energy to melt 1 g of ice is 334 J and the released energy when 1 g of water is frozen to ice is the same 334 J, if we want to melt 10 kg of ice, a higher amount of energy well be required in comparison to the released energy when 1 kg of water freezes, which is about 334000 J for the melting of those 10 kg of ice and only 334 J for the freezing of that 1 kg of water.

Best regards!

The atom is one of the basic units of matter. Which part of the atom mostly determines the size of the atom?

dedylja [7]

Answer:

Atomic size is the distance from the nucleus to the valence shell where the valence electrons are located. The separation that occurs because electrons have the same charge. The number of protons in the nucleus. The core electrons in an atom interfere with the attraction of the nucleus for the outermost electrons.

The proposed mechanism for a reaction is 1. ClO-(aq) + H2O(l) => HClO(aq) + OH-(aq) SLOW 2. I-(aq) + HClO(aq) => HIO(aq) +

HACTEHA [7]

Answer:

The correct answer is option A.

Explanation:

Step 1 : Slow

$ClO^-(aq) + H_2O(l)\rightarrow HClO(aq) + OH^-(aq)$

Step 2: Fast

$I^-(aq) + HClO(aq)\rightarrow HIO(aq) + Cl^-(aq)$

Step 3: Fast

$OH^-(aq) + HIO(aq)\rightarrow H_2O(l) + IO^-(aq)$

When there is a recation which is taking place in a more that single steps than the rate of the reaction is determined by the slowest step occurring in the reaction mechanism.

So, according to question step 1 is slow step which means that rate of the reaction will be :

$R=k[ClO^-][H_2O]$
