Magnesium reacts with oxygen present in air to produce magnesium oxide;
2 Mg + O₂ → 2 MgO
This reaction doesn't start on its own but requires a initiation energy called activation energy. When provided with this activation energy with the help of Bunsen burner it will start a spontaneous reaction because the further energy required for reaction is generated by itself.
The answer is D because I don't see how energy is being converted by looking at yourself in the mirror.
The idea that atoms are unstable would have been strengthened because the orbiting electron would lose energy and fall into the nucleus.
Answer:
For this experiment we are going to take plate 1 as the control plate, so, in it there will be just E. coli in LB/agar; in plate 2, we are going to put E. coli in LB/agar and some ampicillin. Then, we have to wait for the E. coli colonies to form. After a while, the E. coli growth can be compared on both plates and determine if ampicillin affects or not the E. coli colonies.
Explanation:
If the ampicillin affects negatively E. coli colonies, we are going to observe that in plate 1 (control plate) there are E. coli colonies growing, but in plate 2, there is no E. coli colonies or, at least, there is a fewer number of colonies on it. If ampicillin doesn't affect E.coli, plate 1 (control) and plate 2 (ampicillin experiment) are going to be similar in number of colonies.
Based on the data given of the bonds listed below, the weakest bond is C-H and the strongest bond is C ≡ C.
A strong bond is a stable bond.
<h3>Which of the bonds listed is the weakest and which is the strongest?</h3>
The strength of a bond is proportional to the amount of energy required to break or form the bond.
A weak bond will require less energy to form than a strong bond.
A weak bond is unstable while a strong bond is stable.
Data provided:
839 kJ/mol C ≡ C
495 kJ/mo O = O
413 kJ/mo C—H
From the data given of the bonds listed below, the weakest bond is C-H and the strongest bond is C ≡ C.
A strong bond is a stable bond.
