In divergent boundaries deep ocean trenches form due to the 2 plates pulling apart. the plate in the middle gets stretched thinner and thinner as it submerges into the sea until enough pressure causes magma to erupt from it. when the magma erupts new sea floor is created
Answer:
Explanation:
The theory or working principle of Atomic Emission Spectroscopy involves the examination of the wavelengths of photons discharged by atoms and molecules as they transit from a high energy state to a low energy state. A characteristic set of wavelengths is emitted by each element or substance which depends on its electronic structure.
Density= 5m^3
Explanation:
Here, the Mass of an object is 25g
To convert grams into kilograms, we need to divide 25 by 1000
so, the 25g=25/1000 = 0.025kg.
The volume of an object is given by 5cm^3 ( cubic centimetre)
To convert cubic centimetre to meter cube, we need to divide 5 by 1000.
So, 5cm^3=5/1000=0.005m^3
Finally, the equation of density is
DENSITY= MASS/VOLUME
Density = 0.025/0.005
= 5m^3
Hence, the density of the object is 5m^3.
Density = mass / volume
Thus, Mass of the solution can be expressed as:
Mass of solution = Density of solution × volume of solution
Given- Density of solution = 1.126 g/ml
volume of solution = 20.0 ml
∴ Mass of 14 wt% solution of CaCl2 = (1.126 g/ml) × (20 ml)
= 22.52 g
= 22520 mg
