What happens when hydrochloric acid is added to zinc powder?
When hydrochloric acid is added to zinc powder, a chemical reaction occurs where zinc reacts with hydrochloric acid to produce hydrogen gas and zinc chloride. The hydrogen gas is evolved as bubbles, and the zinc chloride remains in solution. This is a typical example of a single displacement reaction.
What happens when you add iron powder to hydrochloric acid?
When iron powder is added to hydrochloric acid, a chemical reaction takes place which produces hydrogen gas and iron(II) chloride. The iron powder dissolves in the acid and the hydrogen gas is released as bubbles. The iron chloride formed remains in solution.
Why magnesium powder reacts more rapidly than magnesium ribbon with hydrochloric acid?
Magnesium powder has a larger surface area, allowing for more contact between the magnesium and the hydrochloric acid, leading to a faster reaction. The increased surface area of the powder results in more collisions between magnesium particles and acid molecules, increasing the rate of reaction.
What happens when mix HCl and iron powder?
When hydrochloric acid (HCl) reacts with iron powder, the iron oxidizes to form iron(II) chloride (FeCl2) and hydrogen gas (H2) is released. This reaction is a typical metal-acid reaction known as a single displacement reaction. The iron powder will dissolve and you will observe bubbling as the gas is released.
A 5.0-gram sample of zinc and a 50-milliliter sample of hydrochloric acid are used in a chemical reaction Which combination of these samples has the fastest reaction rate?
The faster reaction rate will likely occur when the zinc and hydrochloric acid are in a greater contact surface area. In this case, the 5.0-gram sample of zinc will have a higher surface area compared to the 50-milliliter sample of hydrochloric acid. Thus, the combination with the fastest reaction rate is the 5.0-gram sample of zinc.
What will happen in the reaction of sodium chloride powder and hydrochloric acid?
Nothing, they don't react with each other

What is the balance chemical equation for the reaction between hydrochloric acid and baking powder?
NaHCO3 + HCl = CO2 + H2O + NaCl
What happens when you add iron powder to hydrochloric acid?

What happen when hydrochloric acid is added to the zinc powder?
When hydrochloric acid is added to zinc powder, a chemical reaction occurs, resulting in the formation of zinc chloride and hydrogen gas. The zinc reacts with the hydrochloric acid to produce zinc chloride, a salt, and hydrogen gas is released as a byproduct. The solution may become warm as the reaction is exothermic.
How would you speed up a chemical reaction?
increase temperature use a catalyst increase concentration increase surface area of what you are reacting (crushing into a powder)
How do you increase the rate of a reaction of a solid?
To increase the rate of a reaction involving a solid, you can try increasing the surface area of the solid by breaking it into smaller pieces or grinding it into a powder, which exposes more surface area for the reaction to occur. Another way is to increase the temperature, as higher temperatures generally lead to faster reaction rates. Additionally, using a catalyst can also help to speed up the reaction.

How could you determine whether a white powder was zinc sulfide or silver nitrate using hydrochloric acid solution?
If the white powder is zinc sulfide, it would react with hydrochloric acid to produce hydrogen sulfide gas, which has a distinct odor of rotten eggs. On the other hand, if the white powder is silver nitrate, no reaction would occur with hydrochloric acid. Thus, by observing whether there is a smell of hydrogen sulfide gas, you can determine if the white powder is zinc sulfide or silver nitrate.
What is the Action of bleaching powder on hydrochloric acid?
When bleaching powder (calcium hypochlorite) is added to hydrochloric acid, it reacts to produce chlorine gas, calcium chloride, and water. This reaction is exothermic and should be carried out in a well-ventilated area due to the toxic nature of chlorine gas.
