Consider the reaction:

Mg(s)+2HCl(aq)→MgCl2(aq)+H2(g)

and the estimation that one mole of gas occupies 22.4 L
at STP.

What minimum amount of 1.35 M HCl is necessary to produce 26.5 L of H2 at STP?

The grooves or folds of the brain are called

Which ocean zone has the most abundant primary producer and why a) the abyssopelagic zone ,du to the absence of light and cold water temperatureb) the bathypelagic zone, due to the absence of light and cold water temperaturec) the mesopelagic zone ,due to uts high light availability and warm water temperature d) the epipelagic zone,due to its high light availability and warm water temperature

Ican determine the molar mass of an element by looking on the under the atomic mass for the element. for example the molar mass of phosphorus is 30.974 grams/mole. avogadro’s number tells me the amount of representative particles in 1 mole of any substance. this means 12.011 gram sample of carbon and a 32.0 gram sample of sulfur have the same number of atoms.
