Density of nitrogen= 1.20 g/l
no. of grams of nitrogen=m= (1.20g/l)(15.0l)= 18 g
molar mass of nitrogen=M= (14*2)= 28 g/mol
no. of moles of nitrogen=m/M=18/28= 0.643 moles
Answer:
hydroxide is the one because it is the one HAHAH
This hypothesis can be further substantiated by having different concentrations of acid and the same mass of limestone.
<h3>Rate of reaction</h3>
Though the question is incomplete, we must try to answer it the much we can. Recall that a hypothesis is a tentative explanation for an observation which is subject to empirical verification.
We know that the rate of reaction depends on the concentration of the acid. This hypothesis can be further substantiated by having different concentrations of acid and the same mass of limestone.
