Pretty sure it's b but not an definitely
Answer:
Option D. Al is above H on the activity series.
Explanation:
The equation for the reaction is given below:
2Al + 6HBr —> 2AlBr₃ + 3H₂
The activity series gives us a background understanding of the reactivity of elements i.e how elements displace other elements when present in solution.
From the activity series of metals, we understood that metal higher in the series will displace those lower in the series.
Considering the equation given above, Al is higher than H in the activity series. Thus, the reaction will proceed as illustrated by the equation.
Therefore, we can conclude that the reaction will only occur if Al is higher than H in the activity series.

Explanation:
Answer:
The answer is "
"
Explanation:
When 
is added in the chemical equation it reacts with sodium acetate so, it will give the following chemical equation:
In this, the 
is a weak acid so, it not completely dissociated.
were strong electrolytes they are completely dissociated.
The 
is a strong acid so, it is completely dissociated So, the net ionic equation is:
Answer:
Spectroscopy
Explanation:
They can determine its composition based on these wavelengths. The most common method astronomers use to determine the composition of stars, planets, and other objects is spectroscopy
