What else can I help you with?
According to collision theory increasing the concentration of the reactants in a chemical reaction increases?
A.the rate of collisions between two particles.
What happens to the individual atoms in a chemical reaction?
Individual atoms in a chemical reaction are rearranged to form new chemical compounds. Atoms are not created or destroyed in a chemical reaction, only the way they are arranged changes. The total mass and number of atoms of each element involved in the reaction remain constant, following the law of conservation of mass.
Why does increasing concentration usually increase reaction rate?
Lncreasing the number of particles in a given volume, means they are more concentrated. Since there are more particles in a given volume it means that they will collide more often with the reacting particles. 'More often' means an increasing rate of reaction.
Which element increases its oxidation number in this reaction 3koh h3po4 k3po4 3h2o?
Phosphorus increases its oxidation number in this reaction. In H3PO4, phosphorus has an oxidation number of +5, and in K3PO4, it has an oxidation number of +5 as well. This means that phosphorus's oxidation state remains the same throughout the reaction.
Why does surface area of a reactant influence the rate of the of the reaction?
by pooing on the leg
Is a change in the number of particles in a suspension a chemical reaction?
This is not a chemical reaction.
What happens to the temperature increase the number of particles what happens to the pressure?
Increasing the temperature the number of particles remain constant and the pressure increase.
Can you increase the number of particles of a substance in a chemical reaction?
No, the number of particles of a substance is determined by the law of conservation of mass, which states that matter cannot be created or destroyed in a chemical reaction. The number of particles remains the same before and after the reaction.
Do the coefficients in a chemical equation represent not only the number of individual particles but also the number of moles of particles?
Yes, the coefficients in a balanced chemical equation represent the ratio of moles of reactants and products involved in the reaction. They do not directly represent the number of individual particles, but they do correspond to the number of moles of particles involved in the reaction according to the stoichiometry of the reaction.
Why are there the same number of of particles at the beginning as at the end of the iron and sulfur reaction?
In a chemical reaction like iron reacting with sulfur to form iron sulfide, the number of atoms of each element in the reactants must equal the number of atoms of each element in the products. This is known as the principle of conservation of mass, which states that matter cannot be created or destroyed in a chemical reaction.
Does adding a catalyst increase the number of particles of a substance available to react in a chemical reaction?
No, the catalyst doesn't increase the number of reactant particles.
Why are there the same number of particles before and after the reaction?
There are the same amount of particles at the end of a reaction as in the beginning of that reaction because of the law of conservation of mass. You simply cannot have particles disappearing to nowhere.
What happens to the reaction rate when reactant particles are able to collide more often and with more energy?
The reaction rate increases because more frequent and energetic collisions between reactant particles lead to a higher likelihood of successful reactions occurring. This is due to an increase in the number of effective collisions, causing the rate of formation of products to accelerate.
Why do we need to know the number of particles in a chemical reaction?
so we can see if anything has changes :)
When double replacement reactions in aqueous solution produce water the number of solvent particles decrease?
Yes, that's correct. In a double replacement reaction where water is produced, the total number of solute particles remains the same, but the number of solvent particles (water molecules) decreases because some of them are consumed in the reaction to form the product.
What does not increase the number of particles of a substance available to react in a chemical reaction?
A change in state (solid to liquid) does not increase the number of particles available to react because the same number of particles are still present in the substance.
What does the number mean at the beginning of a chemical equasion eg 3Al2O3?
The numbers at the beginning of a chemical equation indicate the stoichiometry or the relative amounts of each reactant and product in the reaction. In the example you provided, "3Al2O3" means that three molecules of aluminum oxide (Al2O3) are involved in the reaction.
