Select the correct answer. when carbon dioxide dissolves in water, it sometimes reacts with water to form carbonic acid as in this balanced equation: co2 + h2o → h2co3. if 495 milliliters of carbon dioxide at 25°c and 101.3 kilopascals reacts with excess water, what is the theoretical yield of carbonic acid? use the periodic table and the ideal gas resource a. 0.889 g b. 1.10g c. 1.27g d. 2.02g what's the answer! quick!

its c. 1.27

Explanation:

The correct answer is option (C).

Explanation:

Pressure of the gas = 101.3 kilopascal

Volume of the gas = 495 mL = 0.495 L

Temperature of the gas = 25°C = 298 K(0°C = 273 K)

Value of gas constant in in kilopascals =8.314 kPa L\K mol

According to the ideal gas equation:'

Moles of carbon-dioxide gas = 0.0202 moles

.

According to reaction 1 mole of gas gives 1 moles , then 0.0202 moles of will produce : moles of that 0.0202 moles.

Mass of = Moles  Molar mass of

=

From the options given the closest value to our answer is of option(C).

Hence ,the correct answer is option C.

atomic number of carbon is 6

electronic configuration of carbon is 1s²2s²2p²

orbital diagram of c is as shown here in the image.
