2) According to the Bronsted-Lowry theory, what does H2O act as in the

Chemistry

6 0

Answer: Option B) Base

Explanation:

According to Bronsted-Lowry theory, an acid is a substance that donates a proton and produces a conjugate base while a base is a molecule or ion which accepts the proton and produces a conjugate acid.

Thus, water H2O acts as a example of Bronsted-Lowry base while hydrochloric acid, HCl acts as an acid respectively as shown in the reaction below

HCl(aq) + H2O(aq) -> H3O+(aq) + Cl-(aq)

H2O acts as an base by accepting a proton donated by HCl, thus producing hydroxonium ion, H3O+ as a conjugate acid.

Thus, in the given reaction, H2O acts as a base

The mass of a 50-mL volumetric flask is 40.638
Kaylis [27]

<em>D</em> = 0.9570 g/mL

Mass of mixture = 88.219 g – 40.368 g = 47.851 g

<em>D</em> = mass/volume = 47.851 g/50.00 mL = 0.9570 g/mL

A two-liter soft drink bottle can withstand apressure of
larisa86 [58]

Explanation:

According to the ideal gas equation, PV = nRT.

where,     P = pressure,        V = volume

               n = no. of moles,      R = gas constant

               T = temperature

Also, density is equal to mass divided by volume. And, no. of moles equals mass divided by molar mass.

Therefore, then formula for ideal gas could also be as follows.

                 P = \frac{mass}{volume \times molar mass} \times RT

or,             P = \frac{density}{\text{molar mass}} \times RT

Since, density is given as 0.789 g/ml which is also equal to 789 g/L (as 1000 mL = 1 L). Hence, putting the given values into the above formula as follows.

               P = \frac{density}{\text{molar mass}} \times RT

                  = \frac{789 g/l}{46.06 g/mol} \times 0.0821 L atm/mol K \times 373 K

                  = 525 atm

As two-liter soft drink bottle can withstand a pressure of  5 atm and the value of calculated pressure is 525 atm which is much greater than 5 atm.

Therefore, the soft drink bottle will  obviously explode.
