Water combines with carbon dioxide to produce slightly acidic groundwater
that dissolves limestone and forms caves.
This is because the reaction between water and carbondioxide to form
bicarbonate ions( HCO₃⁻). The bicarbonate ions dissociate into Hydrogen
atoms thereby increasing the acidity.
The acidic environment results in the formation of acidic groundwater that
dissolves limestone and forms caves.

For a reaction to occur, there should be mobility of ions in reactant side.
If the reactant is larger, its mobility will be lesser than that of smaller ones.
So reactants smaller in size have higher mobility which makes reaction faster.
Hence D is the correct option.
Hope this helps, have a great day/night ahead!
A lone pair is a pair of valence electrons that are not shared with another atom and is sometimes called a non-bonding pair.
Answer:
Explanation:
We are given the percent composition: 22.5% phosphorus and 77.5% chlorine.
We can assume there are 100 grams of this compound. We choose 100 because we can simply use the percentages as the masses.
Next, convert these masses to moles, using the molar masses found on the Periodic Table.
- P: 30.974 g/mol
- Cl: 35.45 g/mol
Use the molar masses as ratios and multiply by the number of grams. 
Divide both of the moles by the smallest number of moles to find the mole ratio.
The mole ratio is about 1 P: 3 Cl, so the empirical formula is written as:<u> PCl₃</u>
Answer:
876 grams
Explanation:
Convert specific gravity to density, using water density 1.0 g/ml
d = e.g x 1.0 g/ml = 1.168 g/ml
d = m/v (mass/volume)
m = dxv = 1.168 g/ml x 750 ml = 876 grams
