Explanation:

Sankey diagrams , which are typically used to visualize energy transfers between processes, are named after the Irishman Matthew H. P. R. Sankey, who used this type of diagram in a publication on energy efficiency of a steam engine in 1898.

Sankey diagrams are ideal for visually representing energy balances.

how to use

1.Overview. The Sankey diagram displays how quantities are distributed among items between two or more stages.

2.Add a Sankey diagram. Choose the Data Visualization or Re-Visualize option from the toolbar and select Sankey Diagram.

3.Change link color and width.

4.Change node color.

5.Change labels and tooltips.

How many grams of CO2 are in 11 mol of the compound?

GrogVix [38]

Well the molar mass of CO2 would be that 1 mol of CO2 would have the mass of 44.0 grams. So 11 mol of CO2 would have 11 • 44 or 484 grams.

The argon atoms are excited into an excited state before emitting the 488.0 nm laser. It is known that the energy of the first i

Answer:

Explanation:

Given that:

The argon atoms are excited into an excited state before emitting the 488.0 nm laser.

the energy of the first ionization energy of argon is 1520 kJ mol-1.

SInce 1 eV = 96.49 kJ/mol

Therefore, the energy of the first ionization energy of argon in eV is = ( 1520/ 96.49) eV

= 15.75 eV

To find where the energy level of the excited state lies below the vacuum energy level, let's first determine, the energy liberated by using planck expression.

$E = \dfrac{hc}{\lambda}$

$E = \dfrac{6.6 \times 10^{-34} \times 3 \times 10^8}{488 \times 10^{-9}}$

$E = \dfrac{1.98 \times 10^{-25}}{488 \times 10^{-9}}$

$E =4.057 \times 10^{-19} \ J$

Converting Joules (J) to eV ; we get,

$E =\dfrac{4.057 \times 10^{-19}}{1.6 \times 10^{-19}}$

E = 2.53 eV

The energy levels of the first exited state = -13.223 eV

Is thiamine mononitrate an ionic bond or covalent bond?

MrRa [10]

It is a covalent bond. Whenever a compound uses such suffixes like mono, di, tri, tetra, and so on, it is a covalent compound- thus having covalent bonds.
