What volume of carbon dioxide is produced when 0.489 mol of calcium carbonate reacts completely according to the following react

Vilka [71]

Answer:

11.0L of carbon dioxide is produced

Explanation:

Balanced equation: $CaCO_{3}(s)\rightarrow CaO(s)+CO_{2}(g)$

According to balanced equation, 1 mol of $CaCO_{3}$ produces 1 mol of $CO_{2}$

So, 0.489 mol of $CaCO_{3}$ produces 0.489 mol of $CO_{2}$

Let's assume $CO_{2}$ behaves ideally.

So, $P_{CO_{2}}V_{CO_{2}}=n_{CO_{2}}RT$

where P is pressure, V is volume , n is number of moles, R is gas constant and T is temperature in kelvin

Plug-in all the values in the above equation-

$(1atm)\times V_{CO_{2}}=(0.489mol)\times (0.0821L.atm.mol^{-1}.K^{-1})\times (273K)$

or, $V_{CO_{2}}=11.0L$

So, 11.0L of carbon dioxide is produced

Explanation:

Mutation is the process in which sudden changes take place within the sequence of amino acids that causes different type of problems. On the basis of nature and conditions mutation can be classified as dominant negative, neomorphic and some others types. Dominant mutation is also called as antimorphic mutation and changes the functions of the molecules that are proteins.
