Answer:
Reactant concentration, the physical state of the reactants, and surface area, temperature, and the presence of a catalyst are the four main factors that affect reaction rate.
Explanation:
Answer:
liquid and solid
Explanation:
Research scientists of scotland discovered a new state of the matter which consists of both liquid and solid. Scientifically there are three states of matter i.e Solid, Liquid and Gas, but now there are chances of one more state of matter which which consists of more than one state of the existing three states of the matter which have both liquid and solid state.
This discovery took place with the help of artificial intelligence of today's world which is transforming the world day by day.
The State is considered to be true as it is thermodynamically stable state of the matter.
If the battery was removed, the energy produced by the battery would not be able to continue its path along the circuit.
Answer: 5.747 * 10^14 Hz
Explanation:
Convert 522nm to m = 522 * 10^-9 m (since 1nm=10^-9m)
If c = wavelength * frequency, where c is the speed of light (3.0 * 10^8 m/s), then you can manipulate the equation to solve for frequency (f).
f = c / wavelength
Plug in the given numbers:
f = (3.0 * 10^8) / (10^-9)
f = 5.747 * 10^14 Hz
Answer:
Explanation:
Molal freezing point depression constant of butanol Kf = 8.37⁰C /m
ΔTf = Kf x m , m is no of moles of solute per kg of solvent .
mol weight of butanol = 70 g
235.1 g of butanol = 235.1 / 70 = 3.3585 moles
3.3585 moles of butanol dissolved in 4.14 kg of water .
ΔTf = 8.37 x 3.3585 / 4.14
= 6.79⁰C
Depression in freezing point = 6.79
freezing point of solution = - 6.79⁰C .
