How many moles of c2h2 are required to produce 0.70 mol of h2o?

0.70 moles of  C₂H₂ are required to produced 0.70 moles of water

Explanation:

Given data:

Moles of water produced = 0.70 mol

Moles of C₂H₂ required = ?

Solution:

Chemical equation:

C₂H₂ + O₂  →  H₂O + CO₂

Balanced chemical equation:

2C₂H₂ + 5O₂  →  2H₂O + 4CO₂

Now we will compare the moles of water with C₂H₂.

                       H₂O       :             C₂H₂

                         2          ;              2

                        0.70      :            0.70  

So 0.70 moles of  C₂H₂ are required to produced 0.70 moles of water.

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
