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.
Well if you want to know 1.2 liters in milliliters the answer is 1200 milliliters and if you want to know 2000 milliliters in liters than the answer is 2 liters.
Answer:
x=13
Step-by-step explanation:
because they're alternate adjacent angles:
5x=78-x
6x=78
x=13
A common tangent is a line that happens to be tangent ("touching but not intersecting a curve or curved surface") to two different coplanar ("in the same plane) circles. I do hope that helped you.
