4.515 x 10^24 atoms of purellium distinkamide is equal to ___ moles?<br><br> 7.5<br> 6.2<br> 19.2
slamgirl [31]

Answer:

Using dimensional analysis, we have....

4.515x1024 atoms x 1 mole/6.022x1023 atoms = 7.4975 moles = 7.498 moles of PD

So the official answer is 7.5

Explanation:

"Purellium Distinkamide" is a silly joke name for a made-up compound. The idea of this question is that no matter what the substance we are talking about is - water (H2O), hydrogen gas (H2), or even "Purellium Distinkamide" - a mole is always the same number of molecules, 6.022 x 1023. This is Avogadro's number and you have probably seen it around class a lot!

How does a buffer resist change in pH upon addition of a strong acid? The strong acid reacts with the strong base in the buffer
MrRa [10]

Answer:

The strong acid reacts with the weak base in the buffer to form a weak acid, which produces few H+ ions in solution and therefore only a little change in pH.

Explanation:

When a strong acid is added to the buffer, the acid dissociates and furnish hydrogen ions which combine with the conjugate of the weak acid, forming weak acid. The weak acid dissociates to only some extent and can furnish only some protons and there is no significant change in the pH.

Hence, option B is correct.

How many grams of water can be formed when 80 grams of sodium hydroxide (NaOH) reacts with an excess of sulfuric acid, H2SO4, in
podryga [215]

Answer:

36g of H2O.

Explanation:

We'll begin by writing the balanced equation for the reaction:

2NaOH + H2SO4 —> Na2SO4 + 2H2O

Next, we shall determine the mass of NaOH that reacted and the mass of H2O produced from the balanced equation. This is illustrated below:

Molar mass of NaOH = 23 + 16 + 1 = 40g/mol

Mass of NaOH from the balanced equation = 2 x 40 = 80g

Molar mass of H2O = (2x1) + 16 = 18g/mol

Mass of H2O from the balanced equation = 2 x 18 = 36g.

From the balanced equation above, we can see evidently that:

80g of NaOH reacted to produce 36g of H2O.
