Given: 8co + 17h2 → c8h18 + 8h2o in this chemical reaction, how many grams of h2 will react completely with 6.50 moles of co? express your answer to three significant figures. grams of h2 will react completely.

- 27.6 grams of hydrogen are required.

Solution:- The given balanced equation is:

From balanced equation, there is 8:17 mol ratio between CO and means 17 moles of hydrogen are required to react completely with 8 moles of CO.

Let's calculate the number of moles of hydrogen required to react completely with 6.50 moles of CO and convert to grams on multiplying by molar mass of hydrogen as:

=

So, 27.6 grams of hydrogen are required to react completely with 6.50 moles of CO.

the equation that correctly represent the reaction for formation of ammonia is

n2+ 3h2 → 2nh3 (answer d)

1 mole of nitrogen gas (n2) react with 3 moles of hydrogen gas (h2) to form 2 moles of ammonia ( nh3). this is in a process known as haber process were iron is used as a catalyst and reaction take place that a higher temperature and pressure. the process is exothermic hence energy is released.

answer: the rate of diffusion increases with increase in temperature.

increase in temperature, increases the molecular/particles speed (kinetic energy. diffusion means movement of particles through the material.

generally, the heavier the particle the more it interacts with the environment and more the temperature matters. so higher temperature results in higher diffusion.
