The right answer is D. three electrons are gained, creating N-3
Nitrogen has 5 electrons in it's valence shell and octet rule states that the valence shell must have 8 electrons. To satisfy that, Nitrogen gains 3 electrons that are negatively charged.Therefore, it gets a negative charge.
An aquifer is D. an underground geological formation that contains a large amount of water.
Isoelectronic species are ions or elements that have equal number of electrons. From the root word, electron of the word isoelectronic. On the other hand, isotructural species are compounds with the same structures.Hope this answers the question.
It should be mass and speed so they are both incorrect because the height doesn’t mean much, but what matters is how heavy the object is, and how fast it’s going to go.
Answer:
Diamond is burnt
Diamond (Carbon)+ Oxygen → CO2
Water electrolysed
2H2O → 2H2 + O2
Explanation:
Dalton atomic theory states that in a chemical reaction, the atoms of the elements join together or combine in simple whole number ratios
Hence when, at very high temperatures, diamond which consists of carbon is burnt we have
Diamond (Carbon)+ Oxygen → CO2
Also when water is electrolysed it decomposes as follows
2H2O → 2H2 + O2
