Which statement is true about crystal lattice energy?

Physics
2 answers:
irinina [24]4 years ago
3 0

The answer is:

It is a measure of the strength of the bonds between ions.

Lattice energy is an estimate of the strength of the bonds formed by ionic compounds.

The first two choices are wrong because it is actually the opposite.

  • As the ion size increases, lattice energy <u>decreases</u>.
  • As charge of ions increases, lattice energy <u>increases</u>

As for the other third option, it is wrong because lattice energy is the energy RELEASED not absorbed.

Answer: The correct option is:

It is a measure of the strength of the bonds between ions.

Explanation:

Lattice energy is defined as amount of energy released on the formation of one mole of crystalline solid from gaseous ions.It is also defined as energy required to break the 1 mole of crystalline solid into its constituting ions in gaseous state that is strength between the ions.

It depends upon two factors:

  • With increase in charge on the ion the lattice energy increases.
  • With increase in the size of the ions the lattice energy decreases.

So, from the given options the correct statement is:

It is a measure of the strength of the bonds between ions.

Why football players boots have spikes their sole<br>Give short and sweet answer​
Marizza181 [45]

Answer:

it helps with balance and speed.

"The football shoes have spikes or studs because the studs or spikes provides larger frictional force than normal shoes while running on the grass. The studs prevents player from slipping on the grass and help to run faster and change direction quickly without slipping"

A sinusoidal wave of angular frequency 1,203 rad/s and amplitude 3.1 mm is sent along a cord with linear density 3.9 g/m and ten
kobusy [5.1K]

Answer:

18.7842493212 W

Explanation:

T = Tension = 1871 N

\mu = Linear density = 3.9 g/m

y = Amplitude = 3.1 mm

\omega = Angular frequency = 1203 rad/s

Average rate of energy transfer is given by

P=\dfrac{1}{2}\sqrt{T\mu}\omega^2y^2\\\Rightarrow P=\dfrac{1}{2}\sqrt{1871\times 3.9\times 10^{-3}}\times 1203^2\times (3.1\times 10^{-3})^2\\\Rightarrow P=18.7842493212\ W

The average rate at which energy is transported by the wave to the opposite end of the cord is 18.7842493212 W

Which term describes the difference in electrical charge across a membrane? View Available Hint(s) Which term describes the diff
Zinaida [17]

Answer:

Membrane potential

Explanation:

Membrane potential is describes the difference in electrical charge across a membrane.                                                                                                              

The difference in potential between exterior  and  interior of the  biological cell is known as Membrane potential.Generally it is denoted by  millivolts like mV and varies from -80 V to -40 V.

So the answer is Membrane potential

A person is filling a knee-high bucket with water using a garden hose and holding it such that water discharges from the hose at
Serggg [28]

Answer:

Yes i am agree with this suggestion

Explanation:

Given that we have to assume that there is no any frictional affects.

As we know that when height increases then the discharge level will decreases when discharge level decreases then the time of filling for the bucket will increase.So the  bucket will fill faster if the hose lowered until knee level.

Yes i am agree with this suggestion
