The mass percent composition of aluminum is 52.9% in aluminum oxide.
Mass of the aluminum = 3.53 g
Mass of the aluminum oxide = 6.67 g.
The mass percent of a substance is the mass of the substance divided by the mass of the compound into 100.
Aluminum reacts with oxygen to form aluminum oxide.
The overall balanced equation for the reaction is,
The mass percent composition of aluminum in the aluminum oxide is,
= 52.9 %
Therefore, the mass percent composition of aluminum is 52.9% in aluminum oxide.

Answer:
Answer would be C because combustion does the process of heat. Oxygen is a reactant in a combination reaction, which always produces energy in the form of heat and light. Carbon burns in the presence of oxygen to give carbon dioxide.

Explanation:If you ride a bike around the block and return to the exact point where you started, your displacement is zero.
By definition, displacement involves changing an object from its original position. No matter how far or for how long a body moves, if it returns to the position it started from, it has not been displaced at all. This means that the body has zero displacements.
This term absolute location refers to using another location as a reference point, rather than using latitude and longitude.
Well it does carry blood and oxygen! Sorry but I'm not sure about 2 and 4.
