If a stronger solution of sodium bicarbonate was used in beaker B, would it require more or less acetic acid to neutralize and w
Dmitriy789 [7]

Answer:

A stronger acid is needed to neutralize the reaction.

Explanation:

Neutral pH solutions are because the acid counteracts the effect of the base, and vice versa.

Both chemical products, both acid and base, reach a pH of 7, which indicates the neutrality of the solution in the reaction, that is, the solution is neither acidic nor basic but NEUTRAL.

The higher the alkalinity of the base, the greater the acidity of the acid will be needed to balance and balance the pH to give neutrality as the final product.

The reaction that occurred when the antacid mixed with the HCl resulted in an additional product (besides a salt and water). Did
QveST [7]

Answer:

Explanation:

If an antacid has sodium hydrogen carbonate/Calcium carbonate, it reacts with HCl as shown

NaHCO₃+ HCl → NaCl + CO₂+ H₂O

Antacid acid salt gas water

CaCO₃+ 2HCl → CaCl₂+ CO₂+ H₂O

Antacid acid salt gas water

The formation of gas CO₂ is shown by brisk effervescence when the antacid (sodium hydrogen carbonate/calcium carbonate) reacts with HCl (acid). So CO₂ is the additional product formed and its formation is supported by observation of brisk effervescence as HCl is added to the antacid.

175.24g of strontium equals how many moles
OverLord2011 [107]
Using dimensional analysis, we can find the moles of strontium by comparing the mass of strontium to it's atomic mass.
You can find the atomic mass of Sr on the periodic table:
Atomic Mass Sr = 87.62g/mol

In case you are not familiar, dimensional analysis works like this:
(what we know) x (conversion factor) = what we are looking for

The conversion factor compares the units of what we know to the units of what we are looking for. In this case, the conversion factor is:
1 mol/87.62g

The important thing to note about the conversion factor is that you want to be able to cancel out the units of your given measurement (in this case, it is the mass)

So, our full solution will be:
moles Sr = (175.24 g)x(1 mol/87.62 g)
(cancel out the mass units)
moles Sr = 175.24 x 1 mol/87.62
= 2.00 mol Sr

Hope this helped you!
