Given the name select the correct formula for each ion compound

A compressor takes 0.50 m3 of a gas at 33°C and 760 mmHg and compresses it to 0.10 m3, cooling it to -55°C at the same time. Wha

vodomira [7]

Answer is C.

Converting temperatures to degrees K: 33 degrees C = 306 K and -55 = 218 degrees K.

By the ideal gas law:-

760 * 0.50 / 306 = P * 0.10 / 218

P = 760 * 0.50 * 218 / 306 * 0.10

= 2700 mm Hg answer

A chemical reaction involves reactant species A, B, and C. Leaving all other factors identical, doubling the concentration of sp

umka21 [38]

Answer:

Rate = k . [B]² . [C]

Explanation:

The dependence of the reaction rate on the concentration of the reactants is given by the reaction order of each one, as shown in the rate equation.

$Rate=k.[A]^{x} .[B]^{y} .[C]^{z}$

where,

k is the rate constant

x, y, z are the reaction orders.

The rate of reaction is not affected by changing the concentration of species A. This means that the reaction order for A is x = 0 since when its concentration changes, the rate stays the same.

Leaving all other factors identical, doubling the concentration of species B increases the rate by a factor of 4. This means that the reaction order for B is y = 2, so when the concentration is doubled, the new rate is 2² = 4 times the initial rate.

The rate of the reaction is linearly dependent on the concentration of C. This means that the reaction order for C is z = 1, that is, a linear dependence.

All in all, the rate equation is:

Rate = k . [B]² . [C]

Why are intermolecular forces generally much weaker than bonding forces?.

swat32

Explanation:

Intermolecular forces: These are the attractive or repulsive forces acting between two molecule in interaction.

The attractive forces between molecules are of several types based on the interaction between molecules also known as Vander wall forces.

Bonding forces: They are also attractive forces acting between two constituents (atom, ion, radicals etc) and stabilizes the constituent particles by loss of energy. The bond between any two species are formed by the overlapping of corresponding orbitals.

Whenever positive overlapping occurs between species, the formation of Bonding molecular orbital (BMO) takes place. and when electron enters into BMO it loses energy. Alternative form of explaining the concept is Individual electron possess more energy than the electrons that paired or Bonded.

Now coming to your question,

All the intermolecular forces are formed by weak attractive forces (vanderwall forces) which includes Ion-dipole forces, Ion-induced-dipole forces, Dipole-dipole forces, Dipole-induced-dipole forces, Hydrogen bonds & London forces.

All these forces are temporary and weak, and formed by the poles generated on molecule due to shift of electron, for e.g. Any molecule having more electron at one pole and less electron at another pole then that molecule start acting as charged body when that charged body comes in contact with opposite pole of another charged body the interaction takes place, since the electrons are dynamic and unsteady it's not possible that the pole will keep acting same as before. hence the intermolecular forces are generally weaker.

On the other side the Bonding electrons, are formed by the various strong overlapping such as between Head to Head overlapping leads to formation of Sigma bond which is the strongest bond takes alot of Energy to break & Lateral overlapping lead to formation of pi bond which is also stronger bond than that of Hydrogen bond.
