2H2 + O2 -> 2H20 Based on the above equation, 2 moles of hydrogen react with 1 mole of oxygen to form 2 moles of water.
Explain what would happen to the amount water produced if you increased the amount of oxygen to 2
moles. What would you need to do to increase the amount of water produced?

Why does his teacher ask him to balance the equation by including the correct coefficient

The volume of helium in a blimp is 6.28 x 10^9 millimeters. the density of helium in the blimp is .1786 kilogram/meter^3. find the mass of the helium in the blimp.

Me i dont know what to do! the table compares the number of electrons in two unknown neutral atoms. comparison of electrons atom number of electrons a 10 d 11 use this information to determine the number of valence electrons in the atoms. which of the following correctly compares the stability of the two atoms? both are unreactive. both are highly reactive. a is unreactive and d is reactive. a is reactive and d is unreactive.
