Answer:
Y, Q, W, Z and X
Y > Q > W > Z > X
Explanation:
To know the most reactive element, the element will be able to displace other metal in it compound. We also have to observe if the reaction occur. If the reaction didn't occur, that means the element is not reactive than the metal found in the other reactant. Invariably their will be no displacement.
Q + w+ Reaction occurs
Q element displace the metal w in it compound . This means Q is more reactive.
x +z+ No reaction
No reaction here. This means x is less reactive than z as it couldn't displace z in it compound.
w + z+ Reaction occurs
w is more reactive than z as it displaces z in it compound.
Q+ + Y Reaction occurs
Y is more reactive than Q as it displaces Q in it compounds.
Therefore, the most reactive to the least reactive is arrange as follows.
Y, Q, W, Z and X
Answer:
I think the correct answer is C.
Answer:
94448421.2201
Explanation:
multiply the value in kilometers by the conversion factor '0.62137119223684'.
So, 152000 kilometers = 152000 × 0.62137119223684 = 94448.42122 miles.
Carbon can be used in fuel
Subatomic particles:
These are too small for people to really know much about them, scientists think that there are only about three: protons, neutrons, and electrons
