Salt hydrates are an important class of PCMs. An inorganic salt hydrate (hydrated salt or hydrate) is an ionic compound in which the ions attract a number of water molecules, which are then trapped inside the crystal lattice. A hydrated salt has the generic formula MxNy. nH2O.

What is the order in which electrons start filling the orbitals?
emmainna [20.7K]

a. 1s 2s 2p 3s 3p 4s 3d 4p is the correct option.

This gives the following order to fill the orbit: 1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 5s, 4d, 5p, 6s, 4f, 5d, 6p, 7s, 5f, 6d, 7p, (8s, 5g, 6f, 7d, 8p, and 9s)

Aufbau's principle states that electrons fill low-energy atomic orbitals before they fill high-energy atomic orbitals. .. By following this rule, you can predict the electron configuration of an atom or ion.

There may be two electrons at the maximum of one orbit. Since the s subplane has only one orbit, it can hold up to two electrons. The p subplane has three orbitals, so it can hold up to six electrons. The d-subplane has five orbitals, so it can hold up to 10 electrons.

Using the average initial pH of your acetic acid solutions (2.96), and the average molarity of those solutions(.0602), calculate
Orlov [11]

Answer : The value of Ka for acetic acid is,  2.03\times 10^{-5}

Explanation :

The chemical formula of acetic acid is, CH_3COOH.

The chemical equilibrium reaction will be:

CH_3COOH\rightleftharpoons CH_3COO^-+H^+

Given:

pH = 2.96

First we have to calculate the concentration of hydrogen ion.

pH=-\log [H^+]

2.96=-\log [H^+]

[H^+]=1.096\times 10^{-3}M

That means,

[H^+]=[CH_3COO^-]=1.096\times 10^{-3}M

[CH_3COOH]=0.0602-(1.096\times 10^{-3})=0.0591M

The expression for reaction is:

K_a=\frac{[CH_3COO^-][H^+]}{[CH_3COOH]}

K_a=\frac{(1.096\times 10^{-3})\times (1.096\times 10^{-3})}{0.0591}

K_a=2.03\times 10^{-5}

Thus, the value of Ka for acetic acid is,  2.03\times 10^{-5}

slamgirl [31]
The answer is (2) Copper. Because copper is consist of atom. If it is decomposed, the atom will be changed. While chemical change is just the break down and form of chemical bonds between atoms.
