4 0

Answer:

Zn. + 2 HCl ----------> ZnCl2. + H2

Explanation:

Mass of Zn in mole = 3.27/ 65.38= 0.050010.... mol

Mass of HCl in mole = 3.3/ 73= 0.044....mol

Hence, limiting reagent is HCl

Molar mass of ZnCl2= 136.38g

Let mass of ZnCl2 be x

x = 3.3*136.38÷ 73 = 6.165...

So, the mass of ZnCl2 is 6.17 g

Which law states that the volume and absolute temperature of a fixed quantity of gas are directly proportional under
Radda [10]

Answer:

O Charles's law .

Explanation:

Hello!

In this case, since the use of gas laws leads to a good comprehension of how gases behave towards volume, pressure and temperature, we can review that the Boyle's law explains the pressure-volume variation, the Dalton's law the partial pressure effect, the Gay-Lussac's law that of pressure and temperature and the Charles' that of temperature and volume at constant pressure; thus, the answer for the asked question is:

O Charles's law

Best regards!
