The acid first has to dissolve away the zinc oxide layer that coats the zinc as more metal gets exposed the acid can react with the exposed metal. Also as the reaction progresses the solution heats up which also speeds the reaction.
Yes, silver will slowly dissolve in hydrochloric acid to form silver chloride and hydrogen gas. However, this reaction is relatively slow compared to other metals like iron or zinc.
When sulfur is added to dilute hydrochloric acid, it reacts with the acid to form hydrogen sulfide gas. This gas is colorless and has a strong odor of rotten eggs. The reaction occurs slowly because of the low reactivity of sulfur with hydrochloric acid, resulting in a delayed release of gas.
Yes, chemicals packed together tightly can react more slowly because there are fewer spaces for the reacting molecules to move and collide with each other. This can lead to a decrease in the rate of reaction due to reduced chances of successful collisions.
Vinegar reacts more slowly with zinc and marble chips because it has a lower concentration of hydrogen ions compared to hydrochloric acid. Hydrochloric acid is a strong acid and dissociates completely in water to produce more hydrogen ions, leading to a faster reaction. Additionally, the presence of chloride ions in hydrochloric acid can also enhance the reaction rate.
It's a precipitation reaction. A yellow precipitate will form, kind of like a bunch of little tiny yellow particles. At first, it will look a little like paint, but if you let it sit, the yellow particles will slowly drift to the bottom.

Magnesium is the element that loses 2 atoms when reacting, reacts slowly with water, and can conduct electricity.
When acid is diluted, the concentration of acid particles decreases. This can decrease the rate of reaction because there are fewer acid particles available to participate in the reaction. Thus, the reaction can proceed more slowly compared to when the acid is concentrated.

Nothing else is needed. Marble will slowly dissolve in HCl to form CO2 and CaCl2. If concentrated HCl is used, then the reaction is faster.
Aluminum is very reactive but it appears to react slowly because first it reacts with air which makes a thin coating of aluminum oxide which has to wear away before there will be any visiual reaction.
To add an acid to a base, you would slowly pour the acid into the base while stirring continuously to ensure thorough mixing. This process is called neutralization and results in the formation of water and a salt. It is important to add the acid to the base slowly to prevent excessive heat generation and splattering.
The pair of reactants that would produce hydrogen most slowly is one that has a high activation energy barrier to overcome in order for the reaction to proceed. For example, a reaction between a less reactive metal like copper and a weak acid like acetic acid would produce hydrogen slowly compared to a more reactive metal like magnesium and a strong acid like hydrochloric acid. This is because the less reactive metal and weak acid combination would have a slower reaction rate due to the higher activation energy required for the reaction to occur.
To handle hydrochloric acid safely, wear appropriate personal protective equipment such as gloves, goggles, and a lab coat, and work in a well-ventilated area. Always add acid to water slowly while stirring to prevent splashes, and never the other way around. Store and transport hydrochloric acid in a designated area away from incompatible materials.
