The list of symbols that represents non metal is P ,S , Cl (answer 4)
Explanation
Non metals are are chemical element that do not have the characteristic of the metals. for example ability to conduct electricity.
List 4 elements that is P ( phosphorous), S (sulfur) and Cl (chlorine) are non metals.
- In list 1 , boron(B) is metalloid) while Ga and Al a metal.
- In list 2, Li and Be are metals.
- In list 3, C is a non metal while Si and Ge are metalloid
In a voltaic cell , the anode electrons and is oxidized , while the cathode electrons and is reduced.
A. The atmosphere
All the other examples are either elements or compounds, not mixtures. A mixture is a combination of elements that are not chemically or irreversibly conjoined so the atmosphere, made up of a variety of gases, would be a mixture.
Answer:
See below ~
Explanation:
The calculated values of V/n :
⇒ 1.5/0.3 = 5
⇒ 3/0.6 = 5
⇒ 4.5/0.9 = 5
⇒ 6/1.2 = 5
⇒ 7.5/1.5 = 5
1. From this we understand that the calculated values of V/n remain constant, equal to <u>5</u> in this case.
2. The volume-mole graph will be a straight line passing through the origin. (Attached below)
CaCl2 + H2O are produced when HCl react with Ca(OH)2
Explanation
equation for reaction is as follows
Ca(OH)2 + 2HCl → CaCl2 +2H2O
1 mole of calcium hydroxide (Ca(OH)2 reacted with 2 moles of hydrochroric acid (HCl) to form 1 moles of calcium chloride CaCl2 and water H2O. This type of reaction is known as neutralization reaction since it between an acid (HCl) and a base (Ca(OH)2
