The differential pressure is
797.9 - 715.7 = 82.2 torr = 138815.25 Pa
The height of the mercury in the open-end arm is calculated using
ΔP = ρgh
The density of mercury is 13560 kg/m3
The height of the mercury is
138815.25 Pa = 13560 kg/m3 (9.81 m/s2) h
h = 1.04 m
Answer:
<u>Reaction is called exergonic when ΔG is negative i.e. ΔG < 0</u>
Explanation:
The Gibbs free energy represents the spontaneity or feasibility of a given chemical reaction at constant pressure and temperature and is given by the equation:
ΔG = ΔH - TΔS
Here, ΔG - change in the Gibbs free energy
ΔS - change in the entropy
ΔH - change in the enthalpy
T - temperature
If the value of <u>ΔG for a chemical reaction is positive i.e. ΔG > 0</u>, then the given chemical reaction is said to be nonspontaneous. Such a reaction is called endergonic.
Whereas, if the <u>ΔG value for a chemical reaction is negative i.e. ΔG < 0</u>, then the given chemical reaction is said to be spontaneous. Such a reaction is called exergonic.
Answer:
Energy of Movement.
Explanation:
Particles in a water wave exchange kinetic energy for potential energy When particles in water become part of a wave, they start to move up or down. This means that kinetic energy (energy of movement) has been transferred to them.
The molar mass of methylammonium bromide is 111u.
<h3>What is molar mass?</h3>
The molar mass is defined as the mass per unit amount of substance of a given chemical entity.
Multiply the atomic weight (from the periodic table) of each element by the number of atoms of that element present in the compound.
Add it all together and put units of grams/mole after the number.
Atomic weight of H is 1u
Atomic weight of N is 14u
Atomic weight of C is 12u
Atomic weight of Br is 79u
Calculating molar mass of
=2(1 x3+ 14+12+ 1 x 3 +79) = 111u
Hence, the molar mass of methylammonium bromide is 111u.
