Calcite (the main mineral in limestone) is made of calcium carbonate (CaCO3). Dolomite, a related
mineral, is made of magnesium carbonate (MgCO3). What happens if a geologist drips a small amount of
vinegar (acetic acid) onto a sample of dolomite?

yes yes yes yes yes yes yes yes yes yes yes yes yes yes yes

explanation:

answer: option (b) is the correct answer.

explanation:

a covalent bond is formed by sharing of electrons. whereas polarity arises due to difference in electronegativity of two atoms.

therefore, more is the electronegativity of an atom which combines with the titanium, more readily it will induce a partial positive and negative charge.

thus, out of the given options fluorine is most electronegative and has an incomplete octet. therefore, it will readily combine with titanium to share the electrons and complete its octet.

explanation:  

tariffs are a tax on anything that are imported from abroad. government use them to protect and boost their local industries and the thought is that they encourage consumers to buy local instead of importing and they will hope will protect jobs and economy in the country that implements them
