The percent by mass of bicarbonate (HCO3−) in a certain Alka-Seltzer product is 32.5 percent. Calculate the volume of CO2 genera
nevsk [136]

Answer:

The volume of carbon dioxide gas generated 468 mL.

Explanation:

The percent by mass of bicarbonate in a certain Alka-Seltzer = 32.5%

Mass of tablet = 3.45 g

Mass of bicarbonate =3.45 g\times \frac{32.5}{100}=1.121 mol

Moles of bicarbonate ion = \frac{1.121 g/mol}{61 g/mol}=0.01840 mol

HCO_3^{-}(aq)+HCl(aq)\rightarrow H_2O(l)+CO_2(g)+Cl^-(aq)

According to reaction, 1 mole of bicarbonate ion gives with 1 mole of carbon dioxide gas , then 0.01840 mole of bicarbonate ion will give:

\frac{1}{1}\times 0.01840 mol=0.01840 mol of carbon dioxide gas

Moles of carbon dioxide gas  n = 0.01840 mol

Pressure of the carbon dioxide gas = P = 1.00 atm

Temperature of the carbon dioxide gas = T = 37°C = 37+273 K=310 K

Volume of the carbon dioxide gas = V

PV=nRT (ideal gas equation)

V=\frac{nRT}{P}=\frac{0.01840 mol\times 0.0821 atm L/mol K\times 310 K}{1.00 atm}=0.468 L

1 L = 1000 mL

0.468 L =0.468 × 1000 mL = 468 mL

The volume of carbon dioxide gas generated 468 mL.

Select the PREDICATE ADJECTIVE(S) (if one or more is present).
creativ13 [48]

<u>Answer:</u> There is no predicate adjective in the sentence.

<u>Explanation:</u>

Predicate adjective is defined as an adjective that follows the linking verb and modifies the subject of the linking verb.

For Example:

The shoes look expensive.

In this sentence, the shoes are the subject, 'look' is the linking verb and 'expensive' is the predicate adjective.

The predicate adjective modified the subject.

In the given sentence,

'Five' is a common noun, 'cookies' is the subject, 'are' is the helping verb, 'on' is the preposition, 'the' is an article and 'table' is a countable noun.

Hence, there is no linking verb and therefore, this sentence has no predicate adjective.
