What role does rubbing the match head on a rough surface have in reaction involved in the burning of a match?
Wiki User

Rubbing the match head mixes together the two chemicals that make up the surface of the match head. Then they react with the air and cause an exothermic reaction.

What does rubbing alcohol do to surface tension?
it decreases it.
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
What is weathering of rock caused by solid particles hitting or rubbing against them called?
Particles of sand or dust rubbing across the surface of rocks is called abrasion.
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.
What happens when Rubbing iron with sand paper?
What happens when you rub sandpaper back and forth over a piece of wood? The strength of the friction force depends upon the types of surfaces involved and how hard the surfaces push together.
What does rubbing alcohol do to surface tension?
it decreases it.
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?

What kind of images are made by chipping or rubbing the surface of a rock?
petroglyphs
How do determine the streak of a mineral?
by rubbing the mineral on a rough hard surface
Do you determine the streak of a mineral?

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 causes molecules to change?
I think this refers to catalysts as these are considered not to be changed by a reaction-- sometimes this true when molecules react on the surface of a catalyst bu sometimes the catalyst does get involved in the chemical reaction- but is regenerated.
What kind of images are made by chipping or rubbing away the surface of a rock?
petroglyphs
