Answer:
Behaviour is in the form of surface tension.
Explanation:
The particles of the liquid are quite close to each other and move with the random movement around the containers. These particles tend to move rapidly in all directions due to the shorter distances between particles. The property of the liquids to flow is their viscosity. Described as the quality of the liquid to flow. They have no fixed shape, as they are made by tiny vibrating particles that are held together by intermolecular bonds. liquids don't disperse like the gases they have surface tension.A sample of gas has a volume of 2.0 liters at a pressure of

What is the mass of zinc required to combine with 0.5 mol of chlorine to produce zinc chloride,ZnCI[subscript 2]?
[Relative atomic mass : Zn = 65]
Answer:
16.25g
Explanation:
Equation for the reaction = Zn + 2Cl = ZnCl2
1 molecule of Zn = 2 molecule of Cl
x mole of Zn = 0.5mol of Cl
mole of Zn = 0.25mol
mass of Zn = 0.25 * 65 = 16.25g
The mass of zinc required to combine with 0.5 mol of chlorine to produce zinc chloride is 16.25g.
What is mass?Mass is the quantity of matter in a physical body.
The reaction is Zn + 2Cl = ZnCl₂
The ratio of moles of Zn and Cl
1 : 2
m, mol of Zn is equal to 0.5 mol of Cl
Moles of Zn = 0.25 mol
Multiply the mole of Zn and the relative atomic mass of Zn
Mass of Zn = 0.25 × 65 = 16.25 g.
Thus, the mass of zinc is 16.25 g.
