B. This is the answer because this statement can be proven and is not an opinion.
Answer:
Barium oxide, BaO, baria, is a white hygroscopic non-flammable compound
Explanation:
so the answer is BARIUM
Chemical reaction: C + O₂ → CO₂.
Law of conservation of mass <span>states that for any </span>system closed<span> to all transfers of </span>matter<span> and </span>energy<span>, the </span>mass<span> of the system must remain constant over time.
</span><span>In </span>chemical reactions<span>, the mass of the chemical components before the reaction (in this reaction carbon and oxygen) is equal to the mass of the components after the reaction (carbon dioxide).
</span>If we use one mole of substances, that:
mass of reactants is: 12 g (C) + 2·16 g (O) = 44 g.
mass of product is: 12 g + 32 g = 44 g.
