Which metal is more active than H2?
Pbs
Why does zinc reacts with DI sulfuric acid to give hydrogen gas but not copper?
If you look at reactivity series, you will find zinc to be more reactive than hydrogen while copper being less reactive than it. Therefore zinc is able to displace hydrogen from sulphuric acid while copper is not. The reaction with zinc is:- Zn + H2SO4 -------> ZnSO4 +H2 The reaction with copper is Cu + H2SO4 ---------> No reaction
Zn plus H2SO4---- ZnSO4 plus H2?
This is a single replacement reaction. The zinc replaces the copper in the sulfate compound. In general, if a reaction occurs between a metal and metal-nonmetal (ionic) compound, the two metals will "switch."
Show experiment for metal and hydrochloric acid?
Acid + Reactive Metal -----> Salt + Hydrogen Gas e.g. 2HCl + Zn --------> ZnCl2 + H2
What is the difference between a bottle of water and a bottle of hydrogen and oxygen gas?
In water (H2O), the hydrogen and oxygen are chemically bonded together. While hydrogen and oxygen are both extremely reactive (read: flamable), they don't spontaneously convert from H2 and O2 into H2O. In order to have the molecular equivalent of H2O in H2 and O2 in a bottle you would also have to have an astronomically higher concentration of H2 and O2 than present in the atmosphere (which is mostly nitrogen).
What element reacts with H2O to produce H2?
All metals more reactive than Zn: Al, Mg, Na, Ca, Ba, K, Li
How does the reactivity of the elements in group 2 change on descending the group?
As you go down the Group 2 (alkaline earth elements) elements they become more and more reactive. i.e. H2O+Ca=Ca(OH)2+H2 there is more hydrogen (g) created and at a faster pace than H2O+Mg=Mg(OH)2+H2.

When calcium react with water why it is CaOH2 H2?
Ca(s) + 2H2O ==> Ca(OH)2(s) + H2(g). This is because of the reactivity of calcium (as opposed to magnesium) so it forms the hydroxide. If it were less reactive, as is magnesium, it would form the metal oxide (if reacted with hot water or steam). Moving down group 2, the metals become more reactive.

Is 2010 Hummer H2 better than a 2011 Honda Pilot?
yes hummer h2 is better than honda pilot because hummer has much more power than honda pilot.

You are 11 years old should you go with the TPX Triton or the tpx H2 for select ball?
if i were you, i would get a h2 becuz they have more pop than a triton.
Which is more powerful hummer h1 or hummer h2?
h2 is more power full
What is an expression for k in hf in chemistry?
Does this mean: How does potassium (capital K, solid reactive metal) react with hydrogen fluoride (capitals HF, weak but reactive acid when in water solution)) then the answer is in the next reaction equation: 2K + 2HF --> 2KF + H2 Products are: KF potassium fluoride, H2 gas, very explosive with air.
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.
Why will the same volume of hydrogen lift more weight than the same volume of helium?
Because He is two times 'heavier' (more dense) than H2
