Why do you need to neutralize the acid first before preparing the salt?

• To make the salt more acidic for better flavor.
• To increase the potency of the acid.
• To prevent the salt from being acidic and potentially harmful.
• To speed up the reaction process.

Why warm up the mixture of copper oxide and dilute sulfuric acid mixture first?

• To decrease the rate of reaction between copper oxide and dilute sulfuric acid, leading to a slower production of copper sulfate and water.
• To increase the rate of reaction between copper oxide and dilute sulfuric acid, leading to a faster production of copper sulfate and water.
• To prevent the reaction between copper oxide and dilute sulfuric acid, resulting in no production of copper sulfate and water.
• To avoid any chemical reaction between copper oxide and dilute sulfuric acid, leading to no change in the mixture.

What are the products formed from the reaction of sulfuric acid and zinc metal?

• Zinc oxide and sulfur dioxide
• Zinc sulfate and hydrogen gas
• Zinc nitrate and carbon dioxide
• Zinc chloride and oxygen gas
• Zinc sulfate and water

The products for reaction between sulfuric acid and copper carbonate are?

• Copper sulfate and water

• Sulfur dioxide, copper hydroxide, and carbon monoxide
