Answer:
The slope is -1/2 or -0.5.
1.2over2=0.6 as molarity then we know that molar volume=22.4dm3
molarity=volume per molar volume
therefore volume=molarity ×molar volume= 0.6 x 22.4= 13.44
Answer:
2 aluminum reacts with sulfuric acid
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
Answer:
copper wire, metal nail, battery
Explanation:
To create an electromagnet, the material to be magnetized (such as a metal nail) is placed inside a solenoid, the ends of the coils are connected to a circuit that includes a battery.
Current is allowed to flow for a few seconds and then cut off. The polarity of the magnet depends on the direction of flow of current in the solenoid.
