A. <em>Concentration in terms of molarity</em>
First, calculate for the molar mass of the given solution, C12H22O11.
m = 12(12) + 22(1) + 11(16) = 232
Calculate for the number of moles.
n = 8.45 g / 232 g/mol = 0.036422 moles
Divide the determined number of moles by volume of solution in L.
V(solution) = (250 mL)(1 L/1000 mL) = 0.25 L
The concentration in molarity is determined by dividing the number of moles by the volume of solution in liters.
M = 0.03622 moles / 0.25 L = 0.146 moles/L
b. <em>Concentration in terms of molality</em>
Calculate the mass of the solvent in kilogram given the volume and its density.
m(solvent) = (1.21 g/cm3)(250 mL)(1 kg/1000 g) = 0.3025 kg
Divide the calculated number of moles by the mass of the solvent in kilograms.
molality = 0.036422 moles/0.3025 kg = 0.12 molal
c. <em>Concentration in terms of weight percent.</em>
The total weight of the solution is equal to 302.5 g.
weight percent of solute = (8.45 g / 302.5 g)(100%) = 2.79%
d. <em>Weight percent in ppm.</em>
weight percent of solute x (10000 ppm/1%)
= (2.79%)(10000 ppm/1%) = 27933.88 ppm
According to the kinetic theory of gases, the force (per unit area) exerted by the atoms striking and rebounding from the surface of the gas container is assumed to be equal to the pressure.
According to the kinetic theory of gases, the force (per unit area) exerted by the atoms striking and rebounding from the surface of the gas container is assumed to be equal to the pressure. The assumption that matter is made up of microscopic particles that are always in motion forms the foundation of the kinetic-molecular theory, which explains the states of matter.
The observable characteristics and behaviours of solids, liquids, and gases are explained by this theory. The kinetic theory of gases has three primary parts, which are as follows: 1) Neither energy is gained nor lost when molecules collide. 2) In a container, the space occupied by gas molecules is extremely minimal. 3) These molecules move in a straight line at all times.

Answer:
The product formed is orthonitrophenol
Explanation:
The compound orthonitrophenol is formed when ortho-bromonitrobenzene is treated with NaOH at elevated temperature.
The reaction leads to the formation of an intermediate stabilized by resonance. This intermediate can not be formed by the meta isomer because a resonance stabilized intermediate can not be formed and the product is not stabilized by intramolecular hydrogen bonding hence this reaction will not occur.
<span>Na (sodium) is highly electropositive. Its has 1 electron in its outermost orbit which is transferred to an electronegative atom to form an ionic bond.
It only needs to get rid of one valence electron to take part in a reaction. That's how it's highly reactive.</span>
