Answer:
The ranking of matter from the LEAST amount of energy to MOST amount of energy is;
B. Solid, Liquid, Gas
Explanation:
The kinetic energy of the particles that make of matter depends on the temperature of the particles and the particles are constantly vibrating
Solid state (Least amount of energy)
In the solid state, the matter is held in solid (rigid) crystal lattice and the particles are rigidly located next to other adjacent particles and stacked up layer by layer
Liquid state (Intermediate amount of energy)
As the temperature of the particles are increased by heating, the particles (atoms and molecules) gain more kinetic energy and their vibration is increased which on further heating, leads to the breaking of the lattice bond of the solid state and the particles are then readjusted to exist side by side rather than being stacked on one another and the assume the liquid state
Upon further heating the particles in the liquid acquire more energy and are and rather than exist side-by-side, they are able to exist as individual particles in the gaseous form
Gaseous state (Most amount of energy)
From the kinetic theory of matter, the molecules of matter in the gaseous state contains enough energy which is more than the intermolecular forces of attraction such that the particles are able to move and occupy the entire volume of the container in which it is placed
Therefore, the correct option is Solid, Liquid, Gas.
Answer:
Mass = 153.48 g
Explanation:
Given data:
Volume of solution = 2.50 L
Molarity = 0.48 M
Mass required = ?
Solution:
Molarity = number of moles / volume in litter
Number of moles = Molarity × volume in litter
Number of moles = 0.48 M × 2.50 L
Number of moles = 1.2 mol
Mass of HI:
Number of moles = mass/molar mass
Mass = Number of moles × molar mass
Mass = 1.2 mol × 127.9 g/mol
Mass = 153.48 g
