We can form an Isosceles triangle using the given measures. Step-by-step explanation: We are given the measure of three sides of a triangle.
Step-by-step explanation:
Zn + 2HCl => ZnCl2 + H2
Moles of Zn = 13g / (65.38g/mol) = 0.198mol
Volume of HCl = 0.396mol / (0.25mol/dm³) = 1.58dm³.
Volume of H2 = 0.198mol * (22.4dm³/mol) = 4.43dm³.
The answer is 9
both 81 and 63 are dividable by 9, and nothing higher
