Answer:
A metallic bond.
Explanation:
Potassium is a metal (alkali metal), hence its bonds are metallic bonds.
Hope this helped!
<u>Answer:</u>
Erlenmeyer flask can be heated up with a Bunsen burner.
<u>Explanation:</u>
A bunsen burner is a lab equipment that is used to heat things that aren't made up of anything flammable. The things that are to be heated with a bunsen burner are instruments of material like borosilicate like pyrex.
An Erlenmeyer flask that also goes by the names conical flask or even a titration flask can withstand a large amount of heat from the bunsen burner as it's made up of very thick and resistant glass. A graduated cylinder will not be able to withstand that amount of heat and a plastic pipette is sure to melt.
Answer:
A) They get oxidized into carbon monoxide and carbon dioxide by the oxygen molecules generated on the electrode.
Explanation:
In the electrolysis of Aluminium, the oxygen reacts with the carbon anodes forming carbon dioxide. That is, the anodes are oxidized. To ensure that the reaction completes, the anode must gradually be replaced as the reaction proceeds. The correct option is hence;
A) They get oxidized into carbon monoxide and carbon dioxide by the oxygen molecules generated on the electrode.
The Bohr model used to be used but it signifies that electrons stay stationary. The current model uses electron clouds in order to predict the location of an electron within an atom.
Additionally, we can predict the location of an electron, but we cannot exactly pinpoint it. So, the current atomic model cannot have a clear and exact placement for every electron around the nucleus of an atom. It also cannot have a clear and distinct border surrounding the nucleus of an atom where electrons are located.
Therefore, the current atomic model has a predicted area surrounding the nucleus where the electron could be located.
