Using the equation 2h2+o2--> 2h2o if 19g of oxygen reacts completely, how many grams of hydrogen must react with it

2.4 grams

Explanation:

To calculate the moles, we use the equation:

For

Given mass = 19 g

Molar mass of   = 32 g/mol

Putting values in above equation, we get:

1 mole of reacts with 2 moles of

0.60 moles of wil react with = moles of

mass of

Thus 2.4 grams of hydrogen will react completely with 19 g of oxygen.

> b takes place in the gas phase in an isothermal tubular reactor. the feed is one mole of a per one mole of c, an inert. the entering temperature and pressure are 427°c and 10 atm, respectively. the gas constant r = 0.08206 atm · l/mol · k.

it forms an anion that has a larger radius. anions have a negative charge and are larger than the original atom.
