Answer: Option (d) is the correct answer.
Explanation:
According to law of conservation of mass, the mass of reactants equal to the mass of products.
Therefore, when liquid 1 and liquid 2 reacts then their respective mass will be equal to the mass of products.
In a chemical equation, reactants are written of the left hand side whereas products are written on the right hand side.
Hence, we can conclude that following equation supports law of conservation of mass.

Lead has a different chemistry than most biological metals, but it can mimic some of them, such as calcium, iron, and zinc, because it tends to form 2+ ion like other metals, and these can be formed inside the body. Due to it different chemistry, lead prevents normal functioning of the enzymes it binds to, inhibiting them and poisoning the body.
Gold rarely forms ions, unless under extreme conditions that are not present in the human body. Gold ions, when ingested, are actually very toxic, so gold poisoning is possible. But because gold are so rare, gold poisoning is also a rare phenomenon.
C.) It was Einstein who created quantum of light
Answer:
When an apple is cut or bruised the oxygen goes into the injured plant tissue. It begins to oxidize from the reaction of the enzymes and oxygen. The apple produces melanin to protect it causing it to brown. Using vinegar and lemon juice help stop the browning because lemon juice has a compound that reacts with oxygen before the oxygen can react with apple. Also, vinegar and lemons are very acidic which slows the browning reaction.
