<span>7.2 g of water.
This is a simple matter of adding up the masses of the initial reactants and determining the mass of the results. You started with 3.2 g of methane and 12.8 g of oxygen. So the total mass you start with is 3.2 + 12.8 = 16.0 grams. The reaction results in water and carbon dioxide. The mass of the carbon dioxide is 8.8 g, so the mass of the water will be 16.0 - 8.8 = 7.2 g.</span>
An object floats if it has low density or has less mass per unit volume. So, Icefloats on water because ICE is lessdenser than WATER. Most of the substances are more dense in their solid state, but water is different. This peculiarity is on account of the structure of ice.
I really hope this helped!!!! ❤
Answer:
4
Explanation:
The balanced equation for the reaction is as follows:
4Al + 3O2 --> 2(Al2O3)
Answer:
The see explanation
Explanation:
In this case, we have an <u>"amine"</u> group in the dopamine structure. So, the dopamine will act as a <u>"base"</u>. A base is a substance that has the ability to <u>accept hydrogens</u>, therefore, the 
will take hydrogen from the water molecule. Additionally, the water will produce the 
ion and the will be converted into 
.
See figure 1
