What is the volume of two moles of hydrogen gas at STP? A. 44.8 L
B. 22.4L
C.
11.2 L
D. 2.00 L

44.8 L

At STP, 2 moles of hydrogen gas have a volume of 44.8 L.

answer: enthalpy

explanation:

for a exothermic reaction, the energy is released i.e. the energy of the products is lower than the energy of the reactants.

= enthaply

= energy of products

= energy of reactants

as , thus comes out to be negative. negative value of enthalpy shows that the reaction is exothermic.

answer: i have one answer

acids are substances that ionize (break off) in an aqueous solution to produce hydrogen (h+) ions

explanation:

hope this and sorry i could only come up with one answer!
