Which reacts faster zinc magnesium lead in sulphuric acid?
Zinc reacts the fastest with sulfuric acid, followed by magnesium, and then lead. Zinc has a higher reactivity compared to magnesium and lead, leading to a quicker reaction when exposed to sulfuric acid.
Why powdered zinc reacts to form hydrogen gas faster than large pieces of zinc when both are placed in hydrochloric acid?
Powdered zinc has a larger surface area compared to large pieces, allowing for a higher rate of reaction with the hydrochloric acid. The increased surface area exposes more zinc atoms to the acid, leading to faster hydrogen gas production.
What is the colour of zinc chloride when zinc reacts with hydrochloric acid?
Zinc chloride is a white crystalline solid when zinc reacts with hydrochloric acid.
What happens when zinc reacts with alcohol?
When zinc reacts with alcohol, it forms zinc alkoxide and hydrogen gas. This reaction is a type of redox reaction where zinc is oxidized and alcohol is reduced.
Which doesn't belong with aluminium zinc bronze and gold?
Zinc doesn't belong with aluminium, bronze, and gold because it is not a precious metal like the others.
Which reacts faster zinc magnesium lead in sulphuric acid?
Zinc reacts the fastest with sulfuric acid, followed by magnesium, and then lead. Zinc has a higher reactivity compared to magnesium and lead, leading to a quicker reaction when exposed to sulfuric acid.

What metal is used in the reaction of metal and air?
Metals in the reactivity series from aluminium to copper react with oxygen in the air to form the metal oxide. Aluminium and Zinc reacts very quickly, Iron reacts slowly at room temperature. Tin, Lead and Copper reacts with Oxygen in air when heated. Silver, Gold and Platinum do not react with Oxygen in air
Which element reacts quickly with hydrochloric acid and bubbles are observed during the reaction but however the same metal does not react with water?
There are many metals including aluminium and zinc.
What is the colour of zinc chloride when zinc reacts with hydrochloric acid?
Zinc chloride is a white crystalline solid when zinc reacts with hydrochloric acid.
What does Sulfuric acid react with in the different metals it reacts to?
It reacts with zinc to form zinc sulfate and hydrogen
What happens when zinc reacts with alcohol?
When zinc reacts with alcohol, it forms zinc alkoxide and hydrogen gas. This reaction is a type of redox reaction where zinc is oxidized and alcohol is reduced.
Which doesn't belong with aluminium zinc bronze and gold?
Zinc doesn't belong with aluminium, bronze, and gold because it is not a precious metal like the others.
What is lighter zinc or aluminum?
Aluminium. Zinc is around two and a half times heavier (more dense) than Aluminium.
Why aluminium sulfate is added to zinc sulfate solution in zinc plating bath?
Transparent
What happens when zinc reacts with phosphoric acid?
When zinc reacts with phosphoric acid, zinc phosphate and hydrogen gas are produced. The reaction is typically exothermic, releasing energy in the form of heat. Zinc phosphate is a white solid that precipitates out of solution.
What happens when aluminium reacts with nitric acid?
Aluminium reacts with dilute nitric acid to give aluminium nitrate and hydrogen gas. aluminium + nitric acid -> aluminium nitrate + hydrogen 2Al(s) + 6HNO3 (aq) -> 2Al(NO3)3 (aq) + 3H2(g)
