It is equal to amount of thymine
The number of units of aluminum chloride (AlCl₃) that can be produced from 30 atoms of aluminum (Al) is 30 units
The balanced equation for the reaction is given below:
2Al + 3Cl₂ — > 2AlCl₃
From the balanced equation above,
2 atoms of Al reacted to produce 2 units of AlCl₃.
With the above information, we can determine the number of units of AlCl₃ that can be produced by the reaction of 30 atoms of Al. This can be obtained as follow:
From the balanced equation above,
2 atoms of Al reacted to produce 2 units of AlCl₃.
Therefore,
30 atoms of Al will also react to produce 30 units of AlCl₃.
Thus, 30 units of AlCl₃ were obtained from the reaction.

28. unbalanced because in reactant side the Aluminium is 1 and oxygen is 2 but in the product side the Aluminium is 2 and oxygen is 3 it is not equal so it is unbalanced equation
29. unbalanced because the oxygen atom are not equal in the reactant and the product side
Follow me pls!!
<span>This could be because no deposition took place or there was a long period of erosion that took away these layers of rocks. A lack of deposition would lead to a large gap in the rock strata, while a long period of erosion would have taken away whatever rocks had existed, leaving what would look like a gap that didn't have any rocks existing.</span>
