Why do atoms emit light energy according to the bohr model?

1 answer:

3 0

Answer: According to the Bohr model, atoms emit light because excited electrons are returning to lower energy states, emitting the energy difference. This energy always has a specific wavelength because the electrons can only exist in set orbits. ... An emission spectrum is the frequencies of light emitted from an atom.

What is the acceleration of the object’s motion? 0.5 m/s2 -0.5 m/s2 2 m/s2 -2 m/s2

djverab [1.8K]

Answer: -2m/s2

Explanation:

Using the following equation ; acceleration = Change in velocity / time

i.e a = v - u / t

where 'a' = acceleration

v = final velocity

u = initial velocity

t = time

Therefore; from the graph we have acceleration to be, 0 - 6m/s / 3s = -2m/s2

Consider the reaction and its rate law.

BaLLatris [955]

The order with respect to A is 2

The order with respect to B is 0.

The overall reaction order is 2.

<u>Explanation:</u>

The rate of chemical equation is represented by its rate equation. Here the rate equation of the given chemical reaction is

$rate=k[B]^2$

Here k represents the rate constant .

Order of the reaction with respect to its individual reactants is represented by the power of the the reactants in the rate equation.

Here the power of the reactant A is 0 and the power of reactant B is 2.

Hence the order with respect to A is 0 and order with respect to B is 2.

The overall order of the reaction is given by the sum of the powers of the reactants in the rate equation.

Hence the total order=2+0=2

A supersaturated solution holds less solute than it normally can.

NeTakaya

A supersaturated solution holds less solute than it normally can is false. It actually contains more solute that it normally can. Having less solute than it normally can is an unsaturated solution. And when it has the exact amount of solute, it is a saturated solution.

So you are using the combined gas law

shusha [124]

Answer:

7.22L

Explanation:

At Stp T2 = 273K and P2 is 1 atm

So we have the following data

V1 =10L. P1=650mmHg(0.855atm)

V2 =V2. P2 = 1 atm

T1=50°c (323K) T2 =273K

Hence from the combined gas law

P1xV1 /T1 =P2xV2/T2

0.855x10/323 =1xV2 /273

8.55/323 =V2 /273

V2 = 8.55x273 /323

V2 = 7.226 L
