The evolution of hydrogen gas on reaction with HCl is faster for magnesium than for aluminium.
1gram alloy of aluminium and magnesium reacted with hcl and formed agcl3 mgcl2 and evolved hydrogen gas . H2 was contained in a container with volume 1200ml at 0 centigrade . Find the composition of aluminium and magnesium in the alloy
When metals like Na, K, Ca react with acids like HCL , Hydrogen gas is evolved. Explain why no evolution of hydrogen gas takes place when the same metals react with HNO3.
Hydrogen diffuses 6 times faster than gas X. The molecular mass for X will be___.
