Water is A. Acidic B. Basic C. Neutral

Chemistry
1 answer:
Mariana [72]3 years ago
8 0

Water acts as an acid (donates H+) when it reacts with a stronger base, say sodium hydroxide. Water acts as a base (accepts H+) when it reacts with a stronger acid, say hydrochloric acid. If the medium is water, water, having a pH of 7, is considered neutral.

A mixture of 117.9 g of P and 121.8 g of O, reacts completely to form P4O6 and P4O10. Find the masses of P4O6 and P4O10
Alex17521 [72]

Answer:

Mass of P4O6=103.4

            P4O10=133.48

Explanation:

Balanced reaction is:

8P +8O_{2}  ⇒P_{4} O_{6} +P_{4} O_{10}

Both reactant completely vanishes as equivalent of bot are equal.

Moles of P=\frac{117.9}{31} =3.80

Moles of O_{2} =\frac{117.9}{31} =3.80

No. of moles of formed product are equal and is \frac{1}{8}th of mole of any of reactant.

Thus weight of  P_{4} O_{6} =\frac{3.80}{8}×220 ≈103.41

        weight of  P_{4} O_{10} =\frac{3.80}{8}×284 ≈133.48

How is an elements outer electron configuration related to its position in the periodic table?
Umnica [9.8K]
Well, if you look at group 1 of the periodic table, you will notice a thrend. All elements in group 1 have 1 valence / outer electron. Then you look at period 2, 3, 4 and so on, you will see that the group number corresponds the number of valence/ outershell electrons. Hence, the group determines the electron(s) on the outershell.

State which of the following set of quantum number would be possible and which would be permissible for an electron in an atom.
raketka [301]

Answer:

The correct option is: e) n=4, l=3, m_{l} = - 2 , m_{s} = - 1/2                                              

Explanation:

The four quantum numbers that describe the electrons in an atom are: The principal: n, azimuthal: l, magnetic: m, and  spin: s.

For a given electron, the values of the quantum numbers should be in the <u>given range</u>- principal quantum number: n ≥ 1;

azimuthal quantum number: 0 ≤ l ≤ n − 1;

magnetic quantum number: −l ≤ m_{l} ≤ +l;

spin quantum number: −s ≤ m_{s} ≤ +s

Now, for n= 4,

The value of l: 0 to n − 1 =  0 to 3 = 0, 1, 2, 3

The value of m_{l} for l= 3 : -3 to +3 = -3, -2, -1, 0, +1, +2, +3

The value of m_{s}: -1/2, +1/2

<u>Therefore, the given set of quantum numbers</u>: n=4, l=3, m_{l} = - 2 , m_{s} = - 1/2;  <u>are possible and permissible for an electron in an atom.</u>
