The balanced equation for the reaction is as follows:
4Al + 3O2 --> 2(Al2O3)
Answer:
B
Explanation:
All elements on both sides of the equation have the same amount of moles
Homogeneous because it is unable to be distinguished of the components Water and Salt
x=3
Use the pythagorean theorem:
a^2 + b^2 = c^2
4^2 + x^2 = 5^2
16 + x^2 = 25
x^2 = 25-16
x^2 = 9
√x^2 = √9
x = 3
