What is the function of watch glass in a laboratory?
Use them to cover beakers to reduce evaporation or prevent stuff falling into it. They can also be used as a reaction surface (glass) since they are slightly concave.
Will crushing calcium carbonate in hydrochloric acid produce more gas?
The total amount of carbon dioxide gas will stay the same if the reaction goes to completion, but if you crush the calcium carbonate, it would make the reaction occur more rapidly, because more surface area would be exposed to the hydrochloric acid.
How does the surface area affect the rate of a reaction?
The powdered solid has a greater surface area than the single lump of solid. So the larger the surface area of the solid, the faster the reaction will be. Increasing the surface area of the solid increases the chances of collision taking place between the molecules of reactants, if it is a reaction in liquid or gaseous phase.
How does surface area of the zinc affect its speed of reaction with sulfuric acid?
The surface is where the reaction takes place. The more surface is exposed, the faster the reaction will proceed. Compared to a chunk of zinc, the same mass of zinc powder can react nearly instantaneously.
Why does grinding a solid into powder increase reaction rate?
Increased surface area for reaction to occur on

What is the effect of reactant surface area on the reaction rate?
surface area has simple constant factor with the rate of reaction. Rate = (surface area)[concentrations with coefficients] the greater the surface area the greater the rate of reaction in a simple constant multiple.
Will a smaller surface speed up a chemical reaction?
No. A smaller surface area will slow down a chemical reaction.
What is the name of a surface membrane molecule that causes an immune reaction?
Antigens are surface membrane molecules that cause an immune reaction.

Is the reaction force on a surface always perpendicular to the surface?
yes i presume
What reaction produces a floating film on waters surface?
It's not a reaction, it is either the difference in density or the effect of the surface tension of the water

does the surface of Antarctica contain grass?
No.
What are watch glasses used for?
Watch glasses are used in chemistry experiments. It is used as a surface for liquid evaporation, It is also used as a holder in weighing solids and as a cover to beakers.

Where surface area is not affect the rate of a reaction?
Surface area affect the reaction rate because the contact between finely divided particles is improved.
