Use the following equations to fill the chart.

E = hf
where
h = 6.63 x 10⁻³⁴ J/s, Planck's constant
f = frequency Hz
E = quanta of energy, J

c = fλ
where
c = 3 x 10⁸ m/s, the velocity of light
λ = wavelength, m

If energy is given in J/mmol, divide by Avogadro's number, N = 6.02 x 10²³, to convert it to J.

The completed table is shown below.

Chemicals used in a laboratory investigation must be safely discarded. Which method is the safest way to dispose of chemicals at
Tema [17]

Answer:

Disposing of the discarded chemicals can be done by certain sfae methods mention as follows:

Explanation:

Most of the chemical wastes are dispose through the EHS waste program. Organic chemicals and solvents that can not be drain should be closed in a tight fitted container that has label on it as Hazardous waste, including strong acid and corrosive liquids.

Recycling of these chemicals and incineration is also use for the industrial chemical waste under professional guidance. Incineration is the process of burning chemicals in to ash through high thermal burning.

Each substance has a unique set of properties that depends on the kinds of atoms it has and how the atoms are connected, or bond
g100num [7]

Both diamond and graphite are allotropes of carbon. Diamond has a high tensile strength but graphite does not.

<h3>What is a molecular model?</h3>

A molecular model is used to describe the actual behavior of a chemical compound based on the kind of bonds that exists in the molecule. Now we are talking about diamond and graphite.

Graphite is composed of hexagonal rings of carbon atoms that form layers that are held together by weak Van Der Walls forces hence they can slide over each other. This is the reason why graphite does not have a high tensile strength.

On the other hand, diamond is made up of octagonal rings of carbon atoms which are rigid and form a strong covalent network solid that explains why graphite has a high tensile strength.

Is BH2F a gas or a liquid and what is the boiling point
hram777 [196]
Hey I tried but could not find your answer, but maybe you could try to calculate the average of bpts of the different elements in the compound to find the boiling point. And when you know the bpt, you can find out whether it is a liquid or gas. But after searching a lot, I found it was a solid. Good luck!
