Which metal is more active than H2?
Potassium is more active than hydrogen (H2) because it readily reacts with water to form potassium hydroxide and hydrogen gas.
Will kilogram of hydrogen contain more atoms then kilogram of lead?
Yes, because each hydrogen atom has less mass than each lead atom.Yes, because each hydrogen atom has less mass than each lead atom.Yes, because each hydrogen atom has less mass than each lead atom.Yes, because each hydrogen atom has less mass than each lead atom.
Explain Will kg of hydrogen contain more atoms than kg of lead?
Since,1 gram of hydrogen contains= 6.02*10 raise to power 23therefore, 1000 grams of hydrogen contains = 6.02*10raise to power 23 * 1000 i.e 6.02*10raise to power 26!!nd 207 grams of lead contains=6.02*10 raise to power 23therefore 1 gram of lead contains= 6.02*10 raise to power 23 / 207hence .. 1000 grams of lead contais= 6.02 * 10raise to power 23 * 1000 / 207= 29.08 * 10 raise to power 23Hence we can say tht hydogen contains more no. of atoms !!
Which kind of chemical will react with an acid to form Hydrogen?
A metal that is more reactive than hydrogen, such as zinc or magnesium, will react with an acid to form hydrogen gas. The metal will displace the hydrogen ions in the acid, resulting in the production of hydrogen gas.
Is hydrogen more reactive than lead?
Hydrogen is so reactive because it only has one electron in its valence shell.
Is hydrogen more active than Zinc?
Hydrogen is more reactive than zinc. Hydrogen reacts readily with many elements, while zinc is considered moderately reactive. Hydrogen's reactivity is seen in its ability to form compounds with a wide range of elements, while zinc tends to form compounds with a more limited subset of elements.
Hydrogen over heated aluminium Nothing observed H over heated copper oxide Red glow spreads and leaves red powder that conducts electricity Why is H more or less active than Al or Cu?
The Pauling electronegativity of hydrogen is higher than the electronegativities of aluminium or copper.And copper is more reactive than aluminium.The red poweder obtained is copper as a metal.
Is Hydrogen more chemically active than Argon?
Yes, hydrogen has one electron and will readily bond with other elements. Argon is an inert gas which does not bond with other elements easily.
What is the mass of a 86.4 milliliter?
Mass is a function of density, not of volume. If your 86.4 ml is of lead, it will have more mass than if it is of hydrogen.
Is hydrogen more explosive than gasoline?
Yes, hydrogen is more explosive than gasoline.
Is hydrogen more flammable than gasoline?
Yes, hydrogen is more flammable than gasoline.
Acids combine with active metals to give off H2?
Yes, when acids react with active metals, they produce hydrogen gas. This reaction is a redox reaction in which the metal displaces hydrogen from the acid to form a metal salt and hydrogen gas is released. This is a common way to test for the reactivity of metals with acids.
