Answer:
Al₄O₅
Explanation:
The key at the bottom tells us the blue spheres are oxygen atoms and the red spheres are aluminum atoms. By counting, there are 4 aluminum atoms and 5 oxygen atoms. Therefore, the formula is Al₄O₅.
Answer:
The two samples have identical properties because they are the samples of the same element. Intensive properties are properties of matter that do not change depending on the amount of matter. Luster, reactivity, and ductility are all intensive properties. That is why the two samples can be different sizes or shapes, but have identical properties.
Hey there :)

By using the formula-

As 1 with 6 zeros, we convert it into exponential form.

As this above value is fraction type, we can do the reciprocal, thus, the exponent gets a negative value.

Now combine with given question.

Answer:
Explanation:
Molecular equation for the reaction:
HI(aq) + KOH(aq) --> KI(aq) + H2O(l)
Ionic equation
K+(aq) + OH-(aq) + H+(aq) + I-(aq) --> K+(aq) + I-(aq) + H2O(l)
Net ionic equation:
H+(aq) + OH-(aq) --> H2O(l)
