VladimirAG [237]2 years ago
3 0

Explanation:

The molecules of the fertilizer after the phase change are more reactive compared to when in solid phase.

  • These molecules in liquid are more free to move about and not fixed as in a solid.
  • This causes the liquid fertilizer to react faster compared to the solid.
  • The solid molecules are in a fixed shape.
  • In the liquids, they slide on top of one another and are free to move better.

Complete the table for ion charge based upon their losing or gaining electrons in the outer shell. (Use the periodic table as ne
PolarNik [594]

Answer:

Explanation:

Group one:

The elements of group one shows +1 charge because these all are metals and lose their one valance electron.

Hydrogen lithium sodium potassium rubidium cesium francium

Group 2:

The elements of group two shows +2 charge because these all alkali metals and lose their two valance electrons.

beryllium magnesium calcium strontium barium radium

Group 3:

The elements of group three-B shoes +3 charge by losing three valance electrons.

Scandium yttrium lanthanum actinium

Group 4:

The elements of group 4th A and 4th B lose four electrons or gain four electrons to complete the octet and shows +4 or -4 charge.

Group 5:

Group 5th elements gain three electrons and shows -3 charge to complete the 8 electrons. (octet).

It involve the elements of group 5th A.

Group 6:

The elements of group 6A gain two electrons to complete the octet and shows -2 charge.

Group 7:

The elements of group 7A gain one electron to complete the octet and shows -1 charge.

Group 8:

The elements of group 8A are noble gases and have complete octet. That's why shows 0 charge.

Katen [24]

<u>Answer:</u>

2.0158 grams

<u>Explantion:</u>

We are to find the mass of the hydrogen atoms in 1 mole of water.

We know that the formula of water is: H_2O

We can see, from the above mentioned formula, that water has 2 hydrpgen atoms.

From the periodic table, we get to know that Hydrogen has an atomic mass of 1.00794 grams.

As there are 2 atoms of hydrogen in water so 2 \times 1.00794 = 2.0158 grams is the answer
