Carbon is special and unique because it is able to form different compounds with a lot of elements, including itself. When it bonds with itself, this is possible because of the concept of hybridization. It is the mixing of atomic orbitals into a new hybrid orbital. In this case, methane is formed through the sp³ hybridization.

Consider the following data for five hypothetical elements: Q, W, X, Y, and Z. Rank the elements from most reactive to least rea
Natalka [10]

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

2C3H7OH + 9O2 -> 6CO2 + 8H2O
MAVERICK [17]

Answer:

Up to 18\; \rm mol \rm CO_2.

Explanation:

The equation for this reaction: 2\; \rm C_3 H_7 OH + 9\; O_2 \to 6\; CO_2 + 8\; H_2O is indeed balanced.

Notice that the coefficient of \rm C_3 H_7 OH is 2 while that of \rm CO_2 is 6.

Therefore, each unit of this reaction would consume 2 units of \rm C_3H_7OH while producing 6 units of \rm CO_2. In other words, this reaction would produce three times as much \rm CO_2\! as it consumes \rm C_3H_7OH\!.

If all that 6\; \rm mol of \rm C_3H_7OH molecules are actually consumed through this reaction, three times as many \rm CO_2 molecules would be produced. That corresponds to 3 \times 6\; \rm mol = 18\; \rm mol of \rm CO_2\! molecules.
