02.04 Slide #2 Fill in the blanks based on the videos T Speed of reaction. When the of the reactants are moving too in a chemica

l reaction, there are fewer between particles. This means there are fewer for particles to correctly. Here you see two particles moving slowly. Though these particles seem ready to react, their slow speeds do not allow them to have the to react in this particular case. Instead, these particles just bounce apart. Particle alignment. If the particles of the reactants in a are not aligned Just right during a collision, they will away from one another. Here you see two particles moving toward each other. However, they are not facing each other in the right way to react. These particles just bounce away from each other.​

You have 16.7 grams of hydrogen and 15.4 grams of oxygen in a synthesis rxn. Which is the limiting reagent?
sleet_krkn [62]

Answer:

oxygen is limiting reactant

Explanation:

Given data:

Mass of hydrogen = 16.7 g

Mass of oxygen = 15.4 g

Limiting reactant = ?

Solution:

Chemical equation:

2H₂ + O₂   →   2H₂O

Number of moles of hydrogen:

Number of moles = mass/ molar mass

Number of moles = 16.7 g/ 2 g/mol

Number of moles = 8.35 mol

Number of moles of oxygen:

Number of moles = mass/ molar mass

Number of moles = 15.4 g/ 32 g/mol

Number of moles = 0.48 mol

Now we will compare the moles of both reactant with product,

                 

                             H₂           :          H₂O

                              2            :            2

                             8.35        :            8.35

                             O₂           :          H₂O

                               1            :            2

                             0.48        :        2×0.48 = 0.96 mol

The number of moles of water produced by oxygen are less so it will limiting reactant.
