Predict the color of the flame for the compound sodium hydroxide, naoh. explain your reasoning.

Chemistry
1 answer:
Lemur [1.5K]4 years ago
6 0
I would predict the color to be yellow-orange because the first element in the formula, and
also the metal, is sodium and therefore would fall under the other sodium formulas that
<span>produced a yellow-orange color.</span>

What elements that have a non polar covalent bond make up the molecule of oil
marissa [1.9K]

Because water is polar and oil is nonpolar, their molecules are not attracted to each other. The molecules of a polar solvent like water are attracted to other polar molecules, such as those of sugar. ( I hope that helps )

I need help with the question in the photo!!
Y_Kistochka [10]

Answer:

a semi-crystalline structure is formed, which holds the water molecules apart, making ice less dense than liquid water, such that it floats. This means that it insulates the water beneath, allowing organisms in the liquid water to survive. Cohesion is the tendency of molecules within a substance to ‘ stick together

What is the standard electrode potential for a galvanic cell constructed in the appropriate way from these two half-cells?

Look up the reduction potential for each cell in question on a table of standard electrode potential like this one from Chemistry LibreTexts. [1]

The standard reduction potential

E

resembles the electrode's strength as an oxidizing agent and equivalently its tendency to get reduced. The reduction potential of a Platinum-Hydrogen Electrode under standard conditions (

,

1.00

l

) is defined as

0

l

V

for reference. [2]

A cell with a high reduction potential indicates a strong oxidizing agent- vice versa for a cell with low reduction potentials.

Two half cells connected with an external circuit and a salt bridge make a galvanic cell; the half-cell with the higher

E

θ

and thus higher likelihood to be reduced will experience reduction and act as the cathode, whereas the half-cell with a lower

E

θ

will experience oxidation and act the anode.

E

Therefore in this galvanic cell, the

the anode.

The standard cell potential of a galvanic cell equals the standard reduction potential of the cathode minus that of the anode. That is:

Indicating that connecting the two cells will generate a potential difference of

across the two cells.
