Use the problem below to answer the question: how many grams of h2 would be formed if 34 grams of carbon reacted with an unlimited amount of h2o? the reaction is c + h2o → co + h2 what substance are we expected to solve for?

Answer : The mass of hydrogen gas will be, 5.6 grams.

Explanation : Given,

Mass of C = 34 g

Molar mass of C = 12 g/mole

Molar mass of = 2 g/mole

First we have to calculate the moles of carbon (C).

Now we have to calculate the moles of .

The balanced chemical reaction is,

From the balanced reaction we conclude that

As, 1 mole of react to give 1 mole of

So, 2.8 moles of react to give 2.8 moles of

Now we have to calculate the mass of .

Therefore, the mass of hydrogen gas will be, 5.6 grams.

explanation:

each principal energy level above the first contains one s orbital and three p orbitals. a set of three p orbitals, called the p sublevel, can hold a maximum of six electrons. therefore, the second level can contain a maximum of eight electrons - that is, two in the s orbital and 6 in the three p orbitals.
