If you mean to name three drugs that work as histamine-2 receptor antagonists, they are Cimetidine, Ranitidine and Famotidine. hope I understood your question correctly.
The 2 in 3H2 represents the number of hydrogen atoms present in the compound. This means there are two hydrogen atoms in one molecule of 3H2.
2NH3 is the product of N2+3H2
Actually, it can't be trihydrogen because 3H2 is equivalent to 6 H. That means 3 times H2 equals to 6 atoms of hydrogen. So, it's not trihydrogen; it's hexahydrogen =)
No, N2 + 3H2 -> 2NH is the formula to make Ammonia, a gas that is present in urine.
The balanced equation for this reaction is: N2(g) + 3H2(g) → 2NH3(g).
The balanced symbol equation for the formation of ammonia is: N2 + 3H2 → 2NH3
The equation for the formation of ammonia is: N2(g) + 3H2(g) -> 2NH3(g)
the haber process the haber process the equation is N2 + 3H2 <--> 2NH3 the haber process! its easy, the equation is N2 + 3H2 <--> 2NH3
The balanced equation for this reaction is: 3H2 + N2 -> 2NH3
The balanced equation for sodium reacting with phosphoric acid is: 3Na + H3PO4 -> Na3PO4 + 3H2
The balanced equation for the reaction between aluminum and hydrochloric acid is: 2Al + 6HCl -> 2AlCl3 + 3H2
The formula for the synthesis of ammonia from diatomic nitrogen and hydrogen is: N2+3H2-->2NH3
