What else can I help you with?
What type of chemical reaction is 2H2O equals 2H2 plus O2?
That is a balanced oxidation-reduction reaction. Hydrogen is oxidized, while chlorine is reduced.
What are two characteristics of combustion reactions?
Combustion is the description of the reaction that results when a substance burns when heat is applied fast enough. Usually combustion also cause a rapid expansion of gasses from the reaction.
What is meant by a stress on a reaction at equilibrium?
A stress on a reaction at equilibrium refers to any change that disturbs the balance between reactants and products. This can include changes in temperature, pressure, or concentration. When a stress is applied, the reaction will shift in a direction that helps to relieve the stress and re-establish equilibrium.
Is peroxide on a sore a chemical change?
Yes, it is. Peroxide, or hydrogen peroxide, H2O2, is a powerful oxidizer. It oxidizes stuff, or causes stuff to combine with the oxygen. The reaction kills bacteria, because they are vulnerable to this destructive chemical. It also "kills" a bit of tissue that is exposed, but not too much. The "big loser" here is any bacterial agent that is exposed to this chemical. When the hydrogen peroxide is put on a wound, oxygen is liberated. That is the reason you see all the bubbles. The H2O2 is unstable, and is being applied as a solution of just a few percent, but the action is fierce. And a good one it is. This stuff is a fabulous "cleaner" of minor wounds, or even major ones. It is applied drop by drop or as a "dribble" to clean out the area of injury before an antiseptic solution or cream is applied or sutures are put on.
Does temperature affect reaction time?
Temperature can affect the length of time a reaction takes (reaction rate) because atomic and molecular activity are somewhat temperature dependent. Certainly the mobility of molecules, atoms or ions has a temperature component. The fact that something like dynamite may be packed in ice won't prevent an explosion if it is set off, but many, many chemical reactions have reaction rates that are temperature dependent. The applied chemistry of the preparation of food broadly exemplifies this phenomenon. In chemistry, the Arrhenius equation speaks directly to temperature dependence of a reaction. Indeed, temperature is a factor in particle behavior as is set down in Boltzman distribution. Links are provided for some further reading.
Why concept of limiting reactant is not applied to reversable reactant?
Concept of limiting reactant is not applicable to the reversible reactions because in these reactions all the reactants are converted into products and no reactants remain at the end of the reaction.
Is screw jack reversible machine?
Screw jack is a non reversible machine,as it does not return to its original position even after the load is applied
What is a reversible word?
A reversible word, or a word that is spelled the same forwards as it is backwards, is called a "palindrome." This term can also be applied to numbers or entire phrases.
What is a 'reversible word' called?
A reversible word, or a word that is spelled the same forwards as it is backwards, is called a "palindrome." This term can also be applied to numbers or entire phrases.

What do you by plasticizers?
plasticity describes the deformation of a material undergoing non-reversible changes of shape in response to applied forces.
How will decreasing the reactant concentration affect the reaction?
It depends on the order of the reaction. If it is zero order, decreasing the reactant concentration will have NO effect on the rate. If it is 1st or 2nd order (or more), then decreasing the concentration will DECREASE the reaction rate.
What do you mean by plasticity?
plasticity describes the deformation of a material undergoing non-reversible changes of shape in response to applied forces.
Is friction and static the same?
Limiting friction is the case of static friction where an object is right on the edge of moving, any more force applied to the object will cause it to move. Limiting friction is the largest value that the static friction can take
What will happen when a reactant is added to a system at equilibrium?
The equilibrium of the system will be upset.
When force is applied to an object but does not cause the object to move?
That will happen if the force applied is less than the limiting value of the friction between the object and the surface that it is in contact with.
How is rusting in an enothermic reaction applied in everyday life?
Rusting is an eXothermic reaction, not an eNDothermic.
