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.
K2O + CaBr2 ---> CaO + 2 KBr
Unable to read second question properly sorry
I am just answering so u can mark the other guy brainliest
In S or shear waves, rock oscillates perpendicular to the direction of wave propagation.
A physical change is when a substance experiences a change in its physical characteristics.
For instance, cutting a diamond or a piece of glass
A chemical transformation is one in which one or more new compounds are created.
Iron rusting, for instance.
Both reversible and irreversible physical change are possible.
On the other hand, chemical change is a change that can never be reversed.
a) Electrolysis of molten MgCl2 involves chemical change since new materials are created and MgCl2 cannot be recovered.
The process of electrolysis involves passing an electric current through a substance to cause a chemical change.
