Why is it good that there is no h2 in the air?
There is, just not (nearly) enough to explode with the oxygen present.
What happens when you add the element sodium to water?
Sodium reacts violently with water. 2Na(s) + 2H2O(l) --> 2NaOH(aq) + H2(g) + heat The heat of the reaction will ignite the H2 gas and make it explode, producing more heat. H2(g) + O2(g) --> H2O(g) + heat If you still have unreacted sodium, the heat from the explosion will cause sodium to ignite and explode. Na(s) + O2(g) --> Na2O2(s) Na2O2 is a peroxide that contains O22-, rather than the O2- ion you normally see.
Why does hydrochloric acid and aluminum explode when closed in container?
The reaction between hydrochloric acid and aluminum produces hydrogen gas. The pressure buildup from the H2 gas production causes the closed container to burst.
How many hudrogen molecule are there in 10grams of hydrogen?
1 mole H2 = 2.016g H2 = 6.022 x 1023 molecules H210g H2 x 1mol H2/2.016g H2 x 6.022 x 1023 molecules H2/1mol H2 = 3 x 1024 molecules H2 (rounded to 1 significant figure)
How many moles of hydrogen gas contained in 9.03x1023?
Given/Known:1mole of H2 = 2.01588g H21mole of H2 = 6.022 x 1023 molecules H21) Convert molecules of H2 to moles of H2 by doing the following calculation.9.4 x 1025 molecules H2 x (1mol H2/6.022 x 1023 molecules H2) = 156mol H22) Convert the moles of H2 to mass in grams of H2.156mol H2 x (2.01588g H2/1mol H2) = 314g H2

What happens when sodium is dropped in cold water?
it grabs electrons from hydrogen and forms H2 which ignites to explode'
What dangers might there be from Hydrogen gas formation when converting an alum crystal?
i think it might be explosion. because H2 is very easy to be explode.

Which has a strong bond H2 or H2 plus?
H2+ has a stronger bond than H2. The addition of a positive charge to the H2 molecule increases the attraction between the two hydrogen atoms, resulting in a stronger bond.
