Why group 1 and group 2 elements do not occur free in nature?
Group 1 and group 2 elements are reactive metals and react readily with water. They also react readily at high temperatures with oxygen. Over the millenia any free deposits would react to form compounds.
What are 2 differences between a crystalline solid and a amorphous?
2 differences are:Crystalline solids Amorphous solids1) Definite geometrical shape. 1) Irregular shape.2) Constituent particles have 2) Constituent particles havelong-range order. short-range order.
How does water reduce the activation of energy for reactions How does matter make chemical reactions possible Why don't solids react outside of aqueous solution?
1.) Water reduces the activation of energy for reactions by lowering the energy needed to break bonds. 2.) Matter makes chemical reactions possible because it isn't created or destroyed. 3.) When dissolved in water, the solids seperate and the ions move around seperately.
Which of these are examples of amorphous solids 1. glass 2. table salt 3. rubber 4. silver?
Glass and rubber are examples of amorphous solids, while table salt and silver are examples of crystalline solids. Amorphous solids lack an organized atomic structure, whereas crystalline solids have a well-defined repeating pattern.
Why does 2-iodobutane react faster than 2-chlorobutane?
2-Iodobutane reacts faster than 2-chlorobutane in an Sn2 reaction due to the larger size of the iodine atom, which makes it a better leaving group. The larger iodine atom polarizes the C-I bond more easily, facilitating the departure of the leaving group and promoting the Sn2 reaction.
Does radium react easily?
Yes it does because it has only 2 valence electron
What do we call a solid that forms when 2 non-solids react?
When a solid suddenly appears when you mix liquids (or gases), you call it a precipitate.
What is a solid shape with 3 surfaces?
A cylinder
What impurities do you find in river water?
1. Suspended solids 2. Colloidal solids (nonsettleable solids) - Do not dissolve in water
What kind of electrons cant move through easily?
The answer 2 this ? is that it is the insulator because the definition is that an insulator is something that cannot move through that well.
Define amorphous solid?
Generally they are two types of solids 1. Crystalline solids 2. Amorphous solids. Amorphous solids are those solids which having different properties in different directions. They didnt have sharp melting and boiling points.
What are 2 example of solids?
Ice And Snow
What are 2 verbs for a solids?
Taxing,tiring
What solids have both flat and curved surfaces?
2
What solids have 2 parallel bases?
A prism and a cube.
What 3 solids have at least 2 faces?
A circle
Platonic solids is made from triangles?
No. Platonic solids, as their name suggests, are 3-dimensional objects. A triangle is 2-dimensional.
