Answer:
a b and c
Explanation:
S is in period 3 so it has 3 electrons
Al is in period 3 so it has 3 electrons
P is in period 3 so it has 3 electrons
Kr is in period 4 so it has 4 electrons
Cs is in period 6 so it has 6 electrons
Explanation:
The balanced reaction equation is as follows.
As it is given that 2.3 times the amount of 
is needed to drive this reaction we can calculate just how much we have, keeping in mind we only need 5 moles of
.
Hence, 
= 11.5 moles of
= 12 (moles approx)
Therefore, it means that 
is our limiting reagent, so product formed will be as follows.
: 
= 1:4 meaning we create 4 moles of
: 
= 1:3 meaning we create 3 moles of 
As, in the given reaction we had 12 moles of , but 5 moles were consumed in the reaction meaning we have:
12 - 5 = 7 moles of
Thus, we will add up all the moles and get the ratios for each gas as follows.
7 + 4 + 3 = 14 moles
![O_{2} = \frac{7}{14} = 0.5 [tex]H_{2}O = \frac{4}{14}](https://tex.z-dn.net/?f=O_%7B2%7D%20%3D%20%5Cfrac%7B7%7D%7B14%7D%20%3D%200.5%0A%3C%2Fp%3E%3Cp%3E%20%20%20%5Btex%5DH_%7B2%7DO%20%3D%20%5Cfrac%7B4%7D%7B14%7D)
= 0.285
= 0.214
Hence, will be consumed completely.
0 is the oxidation state of Mg in Mg(s). Hence, option C is correct.
<h3>What is an oxidation state?</h3>
The total number of electrons that an atom either gains or loses in order to form a chemical bond with another atom.
The oxidation number of an atom is zero in a neutral substance that contains atoms of only one element.
Hence, option C is correct.
