C.
A helium atom will not bond with the sodium atom because, in order to form a good ionic bond, the charges of the atoms in the molecule must cancel out. Because helium's charge is zero, it does not need to bond with anything. Helium also has a complete octet of electrons, which makes bonding impossible in the first place.
The calcium and lithium ions will not form a bond with the sodium because their charges wont cancel out the sodium's plus one charge.
The fluoride ion, however, will cancel out sodium's charge. Their charges sum up to equal zero. Fluoride will form an ionic bond with the sodium, which forms a NaF molecule.
Answer:
The answer should be A
Explanation:
because the definition of a subscript is that they indicate the number of atoms of an element present in am molecule or formula unit.
Answer:
See explanation and image attached
Explanation:
The reaction shown here is the reaction between an acyl chloride and a carboxylic acid. This reaction produces an acid anhydride.
The first step in the reaction is the nucleophillic attack of the acid on the acyl carbon of the acyl chloride. This is followed by loss of HCl to yield the acid anhydride as shown in the image attached.
The product formed is PhCOOCOCH3.
