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.

The answer is B

To write the equilibrium constant for an equation, all you have to do is divide the products by the reactants. The reactants are always on the left side, and the products are always on the right side. The coefficients of the elements will be written as the exponent of that same element. However, in this equation, we do not have to write any exponents, as there are no coefficient but 1.

1s22s22p63s23p3<br> what element does this represent
s344n2d4d5 [400]

Answer:

Its phosphorus (P)

Explanation:

In writing the electron configuration for Phosphorus the first two electrons will go in the 1s orbital. Since 1s can only hold two electrons the next 2 electrons for Phosphorous go in the 2s orbital. The next six electrons will go in the 2p orbital. The p orbital can hold up to six electrons. We'll put six in the 2p orbital and then put the next two electrons in the 3s. Since the 3s if now full we'll move to the 3p where we'll place the remaining three electrons. Therefore the Phosphorus electron configuration will be 1s22s22p63s23p3.
