Why sand paper is used in rubbing magnesium in chemical reaction?
Sandpaper is used to rub magnesium in a chemical reaction to expose fresh, clean magnesium metal for the reaction to occur effectively. By removing any oxidation layer on the surface of magnesium using sandpaper, the reaction can proceed smoothly and efficiently. This process ensures a better contact between magnesium and the reactants, leading to a more vigorous and successful reaction.
What is the effect of rubbing on surfaces?
Rubbing on surfaces can generate friction, which can lead to wear and tear on the surface material. It can also create heat due to the energy generated from the friction. Additionally, rubbing can transfer particles or substances between the rubbing surfaces.
What does rubbing alcohol do to surface tension?
Rubbing alcohol reduces the surface tension of water by breaking up hydrogen bonds between water molecules. This results in the water spreading out more easily and evaporating faster.
Does water or rubbing alcohol dissolve the fastest?
Rubbing alcohol typically dissolves faster than water due to its lower surface tension and ability to break down substances more easily.
What is the controlling factor in very fast heterogeneous reaction?
In very fast heterogeneous reactions, the controlling factor is typically the rate of mass transfer of reactants to the reaction surface, rather than the intrinsic chemical reaction rate at the surface. This is because the reaction rate is limited by how quickly reactants can reach the surface and participate in the reaction. Improving mass transfer, for example by increasing surface area or stirring the system, can enhance the overall reaction rate.
What is rubbing of one object or surface?
Rubbing of one object or surface against another creates friction, which is the resistance that occurs when two surfaces move against each other. This can lead to wear and tear on the surfaces involved and generate heat.

How can you make a glass surface to have a positive surface charge?
You can make a glass surface have a positive surface charge by rubbing it with a material that transfers electrons to the glass, such as a silk cloth or a piece of fur. This transfer of electrons can leave the glass with a net positive charge on its surface.
How is friction involved in trying to move something too heavy?
Well friction is caused by two things rubbing against each other (like rubbing your hands together and they get warm is an example of friction) so if you tried to move something to heavy you might end up dragging it and then it would be rubbing (scraping) against another surface thus creating friction.
What will rubbing alcohol do to your computer screen?
Over time, rubbing alcohol may deteriorate the plastic surface of an LCD, which can cause it to discolor or even crack, so it is not recommended as a regular cleaner for computer displays. Occasionally, however, there may be need to use rubbing alcohol for stubborn smudges or spots, so if you need to use rubbing alcohol in such a scenario, be sure to thoroughly wipe the area with a neutral cleaning solution (ionized water, or a neutral product such as iKlear or Endust for Electronics) afterwards to prevent prolonged chemical reaction between the alcohol and the display surface.
How do you fix grand thief auto 4?
By rubbing the surface of it with your shirt.
Do you determine the streak of a mineral?

What kind of images are made by chipping or rubbing the surface of a rock?
petroglyphs

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.
