<span>I would say Antimony (Sb). Similar chemical properties are usually found within the same column of the periodic table. Look at the element above and below arsenic. I chose Sb since it is also a metaloid and Phosphorus is a nonmetal.
hope that helps </span>
As you move from left to right of the periodic table, the element becomes more negative.
Answer:
Coefficient: number balancing sulfuric acid in a chemical reaction.
Subscripts: number of atoms of each element forming the compound.
Explanation:
Hello!
In this case, since sulfuric acid is a molecule containing hydrogen, sulfur and oxygen in the following way:
- Two hydrogen atoms.
- One sulfur atom.
- Four oxygen atoms.
We can notice the 2 at H represents those two hydrogen atoms, the subscriptless S represent that 1 sulfur atom and the 4 at O represents those four oxygen atoms.
Moreover, since the molecules is given as 7 H2SO4
; from stoichiometry, we infer that every number preceding the molecule stands for a coefficient which is used to balance a undergoing chemical reaction reaction.
Best regards!
