The reason iodine, I2, exists as a solid at room temperature, while bromine, Br2, exists as a liquid at the same temperature, is because: <span>Iodine molecules create stronger London dispersion forces than do bromine molecules.</span>
Answer:
36 mL of water can be displace by the 408 g lead
Explanation:
Given data:
Mass of lead = 408 g
Volume of water displaced by lead = ?
Solution:
The volume of water displace by the lead would be equal to the given volume of lead.
So we will calculate the volume from given mass of lead from density formula.
Density:
Density is equal to the mass of substance divided by its volume.
Units:
SI unit of density is Kg/m3.
Other units are given below,
g/cm3, g/mL , kg/L
Formula:
D=m/v
D= density
m=mass
V=volume
Density of lead is 11.36 g/cm³.
d = m/v
11.36 g/cm³ = 408 g/ v
v = 408 g/ 11.36 g/cm³
v =36 cm³
1 cm³ = 1 mL
volume = 36 mL
36 mL of water can be displace by the 408 g lead.
Answer would be neither!
The reason being that it can take the shape and volume of anything.
