A student reacts Mg and HCl together. The product of this reaction is H2 gas and MgCl2. The balanced equation for this reaction is Mg + 2HCl → H2 + MgCl2
If I need to create 50 L of H2 how many moles of HCl should I start with?
a) 2.3 mol HCl
b) 4.5 mol HCl
c) 1.1 mol HCl
d) 44.6 mol HCl

out of these options:

ability to burn paper

pure sodium reacting violently with water

the boiling point of water

helium does not tend to react with anything

i would say this is a physical property:

helium does not tend to react with anything

why? :

i said helium does not tend to react with anything because well, it reacts to ! but ability to burn paper, pure sodium reacting violently with water, & the boiling point of water are chemical or

physical properties: the properties of a substance that can be observed without changing the chemical makeup of the substance

chemical properties: properties of a substance relating to the chemical nature and reactivity of the substance

with this one i know the answer in craters one reason i looked it up and i learned about it there is my evidence

answer: i dont know the answer but this might

explanation:
