The order of a reaction can be fractional, whereas molecularity (the number of molecules involved in the reaction)
It is always a whole number and cannot be fractional
A moving charged particle is surrounded by both an electric field and a magnetic field.
The electric field is due to the charge itself, and the magnetic field is generated due to the particle's motion.
Homogeneous liquid equilibria can be affected by temperature changes,
It as the temperature can influence the equilibrium position.
Pressure changes may also affect equilibria but to a lesser extent than temperature changes.
Polarization is a property of transverse waves, where the direction of vibration can be oriented in various directions.
Ultrasonic waves are longitudinal waves and cannot be polarized.
All the listed fields (gravitational, electric, and magnetic) are conservative fields.
In conservative fields, the work done moving a particle between two points is independent of the path taken.
The Born-Haber cycle is used to calculate the lattice energy of an ionic compound,
which is the energy required to form the ionic lattice from its gaseous ions.
The molar mass of CaCO₃ is approximately 100 g/mol.
The molar mass of calcium (Ca) in CaCO₃ is about 40 g/mol.
The proportion of calcium in CaCO₃ is 40/ 100 = 0.4
Therefore, in 0.1 g of CaCO₃, the amount of calcium is 0.1×0.4=0.04 g.
Exophthalmia and Graves' disease are related to thyroid gland dysfunction.
Graves' disease is an autoimmune disorder
That causes hyperthyroidism, and exophthalmia (bulging eyes) is a common symptom of this condition
Epinephrine (adrenaline) is used as a bronchodilator to treat asthma
They as a heart stimulant in emergencies, such as during cardiac arrest.
The range of a projectile is the same for two complementary launch angles (i.e., they add up to 90°).
For example, a projectile launched at 30° and 60° will have the same range.
