Answer:

You can easily predict the group of any element by it's valence shell configuration. If the valence e confgn is ns1 then it belongs to 1 group if it is ns2 then it is 2 group element. For p block elements it is 10+ no of es of ns& np. Eg. Cl 3s2 3p5. So group no is 17. For d block elements group no is equal to ns+ (n-1) d es. For e.g. Cr 4s1 3d5 . Group no is 6. For f block elements group no is always 3.

matrenka [14]

Answer:

Density should be 8.5

Explanation:

When you subtract 17.2-10.0 for water displacement you get 7.2 which is the volume and you divide it by 15.7 so your equation will be 15.7/7.2 = 8.5

The difference between the outer covering of plants and animals is that plant cell has cellulose cell wall while animal cell is surrounded by a cell membrane

<h3>What is a cell?</h3>

A cell is the structural and functional unit of an organism which is capable of existing alone as it contains organelles that perform specific functions.

The plant cell is covered by a rigid cell wall which contains cellulose as its outer covering.

The animal cell contains not cellulose cell wall at its out covering but instead it is covered by a cell membrane.

Therefore, the difference between the outer covering of plants and animals is that plant cell has cellulose cell wall while animal cell is surrounded by a cell membrane.
