A base has Kb of 2.5 x 10-11. which of the following statements is true?(1 point)

Chemistry

Furkat [3]3 years ago

I disagree with the answer pick of D. If you have a neutral pH 7 solution and you proceed to add a base even with an relatively insignificantly low Kb your solution would still be more basic then acidic. The answer should be b which is true that the base only ionizes slightly in aqueous solution. This is also truer to the definition of what Kb represents.

Glucose, C6H12O6, is used as an energy source by the human body. The overall reaction in the body is described by the equation C
Crank

Answer:

70.3824 grams of carbondioxide is produced.

Explanation:

C_6H_{12}O_6(aq)+6O_2(g)⟶6CO_2(g)+6H_2O(l)

Moles of glucose =  \frac{48.0 g}{180 g/mol}=0.2666 mol

According to reaction 1 mole of glucose reacts with 6 mole of oxygen gas.

Then 0.2666 mol of gluocse will reactwith :

\frac{6}{1}\times 0.2666 mol =1.5996 mol of oxygen

Mass of 1.5996 moles of oxygen gas:

1.5996 mol\times 32 g/mol = 51.1872 g

51.1872 grams of oxygen are required to convert 48.0 grams of glucose to CO_2 and H_2O.

According to reaction, 1 mol, of glucose gives 6 moles of carbon dioxide.

Then 0.2666 moles of glucose will give:

\frac{6}{1}\times 0.2666 mol =1.5996 mol of carbon dioxide

Mass of 1.5996 moles of carbon dioxide gas:

1.5996 mol\times 44 g/mol = 70.3824 g

70.3824 grams of carbondioxide is produced.
