The answer is N - N.
Purely covalent bond is formed by sharing electrons of atoms with same electronegativity to meet the octet rule (2 or 8 electrons in the valence shell).
Ne is a noble gas and has already 8 electrons in the valence shell, so it will not form a Ne - Ne bond.
Na is an alkaly metal with 1 electron in the valence shell and it does not form a true ionic bond but what is known a metallic bond.
N is a gas that forms a diatomic molecule N - N by sharing the valence electrons in a purely covalent bond.
Ni - O is a metal - non metal compound so it has a ionic character.
Answer: 23.8889
Explanation:
(75°F − 32) × 5/9 = 23.889°C
A cherry red complexion would be the least trustworthy result when evaluating a client who had carbon monoxide poisoning suspicions.
Carbon monoxide poisoning:
- When present in sufficient quantity in the surrounding air, the odorless, colorless, and toxic gas known as carbon monoxide (CO) can result in rapid sickness and death. Using alternative fuels or electrical for warming, chilling, or cooking during power outages during situations like storms or winter storms can result in carbon monoxide(CO) buildup in a house, carport, or camper, which can harm the occupants and their pets.
- It is never a good idea to use a generator, grill, camp stove, or any other appliance that burns fuel, kerosene, natural gas, or charcoal inside a house, basement, garage, camper, or even outside next to an apartment window or windows air conditioner.
- Carbon monoxide poisoning can cause a variety of non-specific symptoms and indications. Migraine, vertigo, fatigue, vomiting, sickness, chest discomfort, and altered mental state are the most typical signs of CO poisoning.

Answer: 3 bromite ions will bind with 
and the chemical formula will be 
.
Explanation:
For formation of a neutral ionic compound, the charges on cation and anion must be balanced. The cation is formed by loss of electrons by metals and anions are formed by gain of electrons by non metals.
Here scandium is having an oxidation state of +3 called as cation and bromite is an anion with oxidation state of -1 called as 
. Thus they combine and their oxidation states are exchanged and written in simplest whole number ratios to give neutral .
Thus 3 bromite ions will bind with and the chemical formula will be .
