It would be B. A polyatomic ion. Poly means many, while atomic refers to atoms more specifically the nature or category of these atoms is that they are non metallic ones, or basically nonmetal atoms. All of these nonmetallic atoms are joined together through covalent bonds and altogether they possess a unique charge. An example of a polyatomic ion would be sulphate or (SO4)^-3.
The answer is a compound.
Hope this helps
The balanced reaction that describes the reaction between sulfuric and sodium hydroxide to produce sodium sulfate and water is expressed <span>H2SO4 + 2NaOH → 2H2O + Na2SO4. When 65.5 grams of sodium hydroxide reacts with excess sulfur, we need first to convert the mass to moles and multiply by stoich ratio 2/2 or 1. Hence the moles is multiplied to the molar mass of water. The final answer is 29.475 grams water.</span>
Answer:
A=covalent B=low melting point
Explanation:
just did this on edge... not sure if it is still needed but there wasn't an answer so :)
