# Which Statement Explains Why A Co2 Molecule Is Nonpolar, Why Is Co2 Non

The nadechworld.com is (3) I always use the acronym SNAPS- symmetrical isN- Non-polarA- asymmetrical isP-Polar

Hydrogen atoms are excited by a laser to the n = 4 state and then allowed to emit. What is the maximum number of distinct emissi

nadechworld.com:The maximum number spectral lines observed will be 6.

You are watching: Which statement explains why a co2 molecule is nonpolar

The wavelength of the 4 to 2 transition will be 486.17 nm.

Explanation:

The formula fro number of spectral lines are given by:

=initial energy level

= final energy level.

Hydrogen atoms are excited by a laser to the n = 4 state .So the number of spectral lines observed will be:

The wavelength of the 4 to 2 transition will be given by Rydberg expression:

” alt=”frac{1}{lambda }=1.097 imes 10^{10} imes ” align=”absmiddle” class=”latex-formula”>

(

)

The maximum number spectral lines observed will be 6.

The wavelength of the 4 to 2 transition will be 486.17 nm.

In the same condition, what happens to the net force acting on the rope?
Cerrena <4.2K>

Explained below

Explanation:

Newton”s law of inertia states that An object at rest will remain continue at rest or if in motion, will continue in motion unless in both cases it is acted upon by a net external force.

Now, If two forces on the rope are equal and opposite forces, then the net force on the rope will be zero and it will not move. Thus,balance force is present in the rope and the rope will remain at rest since the net force is zero or it will continue in motion if already in motion without stopping since net force is zero

However, if the forces are acting in the same direction, it will result in an unbalanced force which means that the net force will be equal to the sum of the two forces and this will result in a stronger force than even the 2 individual forces and consequently it will cause the rope at rest to move, or if the rope is in motion, it will cause it to stop.

A flexible container is put in a deep freeze. Its original volume is 3.00 m3 at 25.0°C. After the container cools, it has shrunk
Lemur <1.5K>
This is an ideal gas problem. The gas inside the balloon is considered ideal. Ideal gas equation is a function pressure, temperature, amount and volume. Note: amount is constant since the balloon ins closed. Pressure is maintained constant since the walls are flexible. Ideal gas equation is: PV=nRT. Put all constant in one side and variables in one. P/nR=T/V. To find the nadechworld.com to the question equate the constants of both situation T1/V1=T2/V2(25+273.15)/3=(x+273.15)/2x=-74.38 degC
