Which is most likely to happen during a single-displacement reaction?
During a single-displacement reaction, one element replaces another in a compound. This reaction is most likely to occur if a more reactive element displaces a less reactive element in the compound. The displacement reaction will result in the formation of a new compound and a free element.
What do you think will happen when an acid and metal come in contact with each other?
When an acid and metal come in contact, a chemical reaction occurs where the metal will dissolve and release hydrogen gas. This reaction is known as a single displacement reaction, where the metal displaces hydrogen from the acid.
What reaction happen between iron and potassium chloride?
When iron reacts with potassium chloride, a single displacement reaction occurs. The iron displaces potassium in the compound, forming iron chloride and potassium metal. The balanced chemical equation for this reaction is 2Fe + 2KCl -> 2K + 2FeCl3.
Describe the collision theory in relation to reaction rate?
When you have a higher concentration of elements in the reaction you are no matter what speed going to have a faster reaction taking place however the lower the concentration it is the more time it will take for the reaction to take place this process is similar to pressure as it reflects how the more of it there is the faster the reaction will be and how if there is less of it the slower the reaction will be. (related to the Collision Theory)
What would happen if you added iron to a solution of magnesium sulphate?
If you add iron to a solution of magnesium sulfate, a displacement reaction would occur, where the iron would displace the magnesium in the sulfate compound. This would result in the formation of iron sulfate and magnesium metal.
Which is most likely to happen during a single-displacement reaction?
During a single-displacement reaction, one element replaces another in a compound. This reaction is most likely to occur if a more reactive element displaces a less reactive element in the compound. The displacement reaction will result in the formation of a new compound and a free element.
When would a displacement reaction cause no reaction?
Displacement reactions happen when one element or ion is more reactive than another in the same solution and replaces it in a compound. This will happen if the elements displacing each other are different metals or are halogens .
What is most likely to happen during a single-displacement reaction?
A more reactive metal pushes out a less reactive metal out of a compound element, eg. CuSo4+Mg=MgSo4+Cu
What do you think will happen when an acid and metal come in contact with each other?
When an acid and metal come in contact, a chemical reaction occurs where the metal will dissolve and release hydrogen gas. This reaction is known as a single displacement reaction, where the metal displaces hydrogen from the acid.
What would happen to entropy in a solid to gas reaction?
It increases; more freely moving particles.
What happens to the motion of gas particles when temperature increases?
They start to move faster, therefore, the reaction will happen quicker. This is because there is more chance of a collision between the particles.
What change could happen during a chemical reaction?
the chemical shall be changed
What are the factors affecting rate of reactoin?
There are 4 factors affecting rate: - Surface area -Temperature - Catalysts -Concentration If the surface area is increased the reaction rate will increase due to more particles being exposed to the reacting chemical, the more particles colliding the quicker the reaction will happen. Temperature causes particles to speed up or slow down, for example in a gas particles are moving very quickly, and therefore they collide more often, this would mean that a reaction would happen quickly since reaction depends on the amount of collisions as well as the strength of collisions. Catalysts are added substances into reactions which only help to speed up the reaction, they are not changed in the reaction and remain the same after the reaction has occurred. If concentration is increased more particles are given the chance to collide, so once again, with more collisions the more quickly a reaction occurs.
What reaction happen between iron and potassium chloride?
When iron reacts with potassium chloride, a single displacement reaction occurs. The iron displaces potassium in the compound, forming iron chloride and potassium metal. The balanced chemical equation for this reaction is 2Fe + 2KCl -> 2K + 2FeCl3.
What happen to large molecules such as food particles during phagocytosis?
During Phagocytosis large particles are enveloped by the cell membrane of a (usually larger) cell and internalized to form a phagosome, or "food vacuole."
When silver nitrate reacts with hydrochloric acid what type of reaction takes place A synthesis B decomposition C double displacement D single replacement?
It is a double displacement reaction.Ag(NO3)3(aq) + 3HCL(aq) ----> AgCl3(s) + 3HNO3(aq)This reaction will happen because there is a solid being formed. I hope that answers your question.
What are four things that happen in the stomach during digestion?
The four things that happen in the stomach during digestion include churning and mashing. This is done to break the food particles into smaller pieces.
