Granules are preferred over zinc strips for the reaction of zinc with hydrochloric acid because granules have a larger surface area, allowing for a faster reaction. The increased surface area of granules results in more zinc atoms being in contact with the hydrochloric acid, leading to a more efficient reaction. This results in a quicker production of hydrogen gas and zinc chloride.
What else can I help you with?
What happens when dilute sulfuric acid is added over zinc granules?
coz when we dilute zinc granules are reacted with dilute HCl (hydrochloric acid), zinc chloride i.e. ZnCl2 is formed along with the evolution of hydrogen gas H2. the presence of hydrogen gas can be tested by bringing a naked flame to the mouth of the test tube. Hydrogen gas burns with a pop sound.
What is the change in color of zinc granules when it reacts with HCL?
The color change of zinc granules when reacting with HCl is not significant. However, over time, the zinc granules will start to lose their shine and develop a dull appearance due to the formation of zinc chloride and hydrogen gas.
What factors contribute to the torquoselectivity of a reaction?
The torquoselectivity of a reaction is influenced by factors such as steric hindrance, electronic effects, and the nature of the reacting molecules. These factors determine the preferred orientation of the reacting groups, leading to the selective formation of one specific product over others.
Why do you add H2SO4 instead of HCL in redox titration?
H2SO4 is preferred over HCl in redox titrations because HCl can release Cl2 gas during the reaction, which can interfere with the titration results. H2SO4 provides the necessary acidic conditions for the redox reaction without introducing additional complications.
What happens when you pour copper over iron?
When copper is poured over iron, they may form a bimetallic strip due to their different properties. Over time, the two metals may undergo a chemical reaction known as galvanic corrosion, causing the iron to corrode in the presence of the copper. This can weaken the materials and lead to degradation of the metals.
Pharmacists often prefer granules over powders because granules offer what advantages?
There are times when pharmacists do prefer granules over powders. The main reasons for this are the granules do not have a tendency to cake up like a powder would and that granules tend to stay dissolved better than powders.
Pharmacists often prefer granules over powders because granules?
don't cake
When Munro found out that Heyward preferred Alice over Cora, what was his reaction?
He thought Heyward was prejudiced toward Cora.
Why does a pharmacists prefer granules over powders?
because unlike a powder, granules don't cake up
What happens when dilute sulfuric acid is added over zinc granules?

Why is PC preferred over laptop?
if you mean why is a desktop preferred over a laptop. then i would answer that they aren't and that laptops are preferred because of their convenience
Why interval estimates are preferred over point estimates?
Interval estimates are generally to be preferred over point estimate
When a plastic strip is hung over the wooden rod the two halves of the strip move away from each other. what are the two conclusions about the acting forces on the strip?
The two conclusions are that the forces acting on the plastic strip are of the same magnitude but opposite in direction, leading to the strip's halves moving away from each other. This demonstrates that the forces are balanced, consistent with Newton's third law of motion stating that for every action, there is an equal and opposite reaction.
What is the change in color of zinc granules when it reacts with HCL?
The color change of zinc granules when reacting with HCl is not significant. However, over time, the zinc granules will start to lose their shine and develop a dull appearance due to the formation of zinc chloride and hydrogen gas.
What is the disadvantage of strip line over micro strip line?
more radiate.
What two states fought over the strip of Toledo?
The two states that fought over the strip of Toledo are Michigan and Ohio.
What factors contribute to the torquoselectivity of a reaction?
The torquoselectivity of a reaction is influenced by factors such as steric hindrance, electronic effects, and the nature of the reacting molecules. These factors determine the preferred orientation of the reacting groups, leading to the selective formation of one specific product over others.
