Cylinder A - Adding 25 grams raised the water level by roughly 3.2 mL

Cylinder B - Adding 25 grams raised the water level by roughly 2.8 mL

Cylinder C - Adding 25 grams raised the water level by roughly 3.5 mL

Calculate grams/mL (density)

A. 25 g/3.2 mL = 7.8125 g/mL = Iron
B. 25 g/2.8 mL = 8.9286 g/mL = Nickel
C. 25 g/3.5 mL = 7.1429 g/mL = Zinc

Hope I helped!

Note: Above question is incomplete: Complete question is read as 
<span>According the the arrhenius theory, which species does an acid produce in an aqueous solution?
</span>A) hydrogen ions B) hydroxyl ions C) Sodium ions D) Chloride ion
.....................................................................................................................
Correct answer for above question is A) Hydrogen ions

Reason:
According the Arrhenius theory of acid and base, acid generates hydrogen ions in aqueous medium, while bases generates hydroxyl ions in aqueous medium.  
Example of Acid:
HCl(aq)          →          H+(aq)    + Cl-(aq)

Example of Base:
NaOH(aq)           →          Na+(aq)       +     OH-(aq)

How does the chemical formula for water influence its chemical properties?
OLga [1]

The chemical formula is composed of hydrogen and oxygen where the two atoms are bonded through hydrogen bond type of bonding. In this pair, the oxygen is the more electronegative atom hence the electrons are more directed to it. Because of this, this creates electron polarity which affects the chemical property of water.
