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.
How does water stick together so well?
The property of surface tension causes water to occupy the least possible surface area, or to put it simply, "stick together".
What effects does distilled white vinegar have on antacid tablets?
It has a chemical reaction and the antacid starts to dissolve. or When you do the white vinegar with the antacid tablets together the tube/bottle explodes and causes a chemical reaction.
What molecular attraction causes surface of the water to curve inside a glass?
The force of adhesion between water and glass molecules is greater than the force of cohesion between two water molecules.This causes the surface of the water to be curved. This curved surface is called a meniscus.
What does the unequal heating of earths surface cause?
It causes wind, with help from the moon's gravitational pull it causes ocean currents and it also helps with the seasons and weather.Windsconvection currentsUnequal heating of the earth's surface results in wind. That is what happens, if that's your question.
What characteristics of a water molecule causes its attraction to a cell membrane?
Water molecules are polar This causes them to be attracted to the cell surface, which is also polar in nature
What change takes place in the cell membrane if a signal molecule causes a transport protein to open?
A permeability change takes place.
Define receptor of body?
A receptor is located on a cell membrane. Any neuronic transmission, hormone, etc. that cannot get inside of the cell's membrane will sit on the receptor in order to pass its message along to the cell. When the molecule sits on the receptor, it causes a series of reactions to occur inside of the cell. From the series of reactions that occur inside of the cell, the message is passed along, and the cell will perform as indicated by the molecule on the cell receptor.
What are the 3 main causes of corrosion?
reaction of metal surface with oxygen (atmospheric generally )cause corrosion
Why does the Mentos and coke reaction die out?
because the surface of the candy is partially dissolved an that removes the factor that causes the eruption
Why does catalyst burn sugar?
Sugar is small crystal powder, thus each sugar crystal has large surface area which causes rapid reaction in presence of catalyst. This reaction produces a lot of heat, as a whole, that it causes sugar to burn.
What molecule causes transformation?
All molecule can react.
What does high surface tension cause water to do?
High surface tension causes water to behave as if its surface had an elastic membrane, which was stretched. Due to water's high surface tension, effects like tears of wine and rain water beading on a leaf or grass happen.
What causes the reaction in chromatography?
physical change causes the reaction in chromatography!
How are symmetric membrane any different from asymmetric membrane?
Symmetric membranes the diamter of pores is constant throughout the cross section of the membrane, as membrane thicknes causes drah to mass transfer. Where as asymmetric membranes the pore size at the surface have a different sixe compared with the holes at the bottom side. Large particles will not enter the the body of the membrane so plugging is avoided.
If a base abstracts a proton from the water molecule what are the products of the reaction?
The products of a base (B-) reaction with water (H2O) are: the conjugate acid of the base (BH+) and a hydroxide ion (OH-) which causes the resulting solution to be basic (pH >7).
Can you develop an infection from an allergic reaction?
Yes, if the allergic reaction causes a disruption to the integrity of the membrane or structure, you can develop a secondary bacterial or viral infection of the area. I had this happen to me - I had an allergic reaction to a chemical in chemistry class on the outside of my ear and developed a secondary bacterial infection that I had to take antibiotics for.
