1) Collide , collision , energy
2 a. The collision where old bonds broke with the use of energy and new bond are formed giving out energy
b. The collision which don't have energy to break a bond and form a bond are called an unsuccessful collision
1) Two particles can react together only if they have a mutual attraction and the mood lighting has enough romantic ambiance to be considered a chemistry experiment.
2) a) A successful collision is when two particles collide with enough energy and the correct orientation for a reaction to occur. It's like two people bumping into each other and realizing they're the perfect match.
b) An unsuccessful collision is when two particles collide but either lack enough energy or are not in the correct orientation for a reaction to occur. It's like two people accidentally bumping into each other but going their separate ways because there's no chemistry.
3) a) The reaction between magnesium and acid speeds up when the concentration of the acid is doubled because it's like adding a second serving of spicy chili to your meal – it increases the number of acid particles available for the magnesium to react with, leading to more frequent collisions.
b) The reaction speeds up when the temperature is raised because it's like turning up the heat in the kitchen – it provides the particles with more kinetic energy, making them move faster and collide with more force, resulting in a higher chance of successful reactions.
c) Stirring the acid speeds up the reaction because it's like giving the ingredients a good mix – it ensures that the acid molecules and magnesium particles are evenly distributed, increasing the probability of collisions between them.
d) Grinding the metal to a powder speeds up the reaction because it's like turning the metal into a magical dust – it increases the surface area of the metal, allowing for more contact between the metal particles and acid molecules, leading to a higher frequency of collisions and faster reaction rates. Plus, who doesn't love a little extra sparkle in their experiments?
1) Two particles can react together only if they collide and the collision has enough energy to be successful.
2)
a) A successful collision refers to a collision between two particles that results in a chemical reaction. In a successful collision, the particles collide with sufficient energy and correct orientation to break existing bonds and form new ones.
b) An unsuccessful collision refers to a collision between two particles that does not result in a chemical reaction. In an unsuccessful collision, the particles either do not collide with enough energy or collide with incorrect orientation, preventing the breaking and forming of bonds.
3)
a) When the concentration of the acid is doubled, the reaction between magnesium and acid speeds up. This is because increasing the concentration of the acid increases the number of acid particles present in a given volume. As a result, there is a higher chance of successful collisions occurring between the acid and magnesium particles, leading to a faster reaction.
b) When the temperature is raised, the reaction between magnesium and acid speeds up. This is because an increase in temperature increases the kinetic energy of the particles, including both the acid and magnesium particles. As a result, the particles move faster and collide more frequently with greater energy, leading to an increased number of successful collisions and a faster reaction.
c) When the acid is stirred, the reaction between magnesium and acid speeds up. Stirring enhances the mixing and distribution of the acid and magnesium particles in the reaction mixture. This increases the chance of successful collisions between the acid and magnesium particles, leading to a faster reaction.
d) When the metal is ground to a powder, the reaction between magnesium and acid speeds up. Grinding the metal into a powder increases its surface area, exposing more particles to the acid. This, in turn, increases the number of acid-magnesium particle collisions and the chances of successful collisions, resulting in a faster reaction.
1) Two particles can react together only if they collide and the collision has enough energy to be effective.
To understand this, let's break it down:
- Particles: In chemical reactions, atoms, molecules, or ions are involved as particles.
- Collide: The particles need to come into contact with each other.
- Collision energy: The particles must have enough energy to break any existing bonds and form new ones in order to undergo a reaction.
- Effective collision: A collision that results in a reaction and the formation of new products.
Therefore, for a reaction to occur, particles need to collide with sufficient energy.
2) a) A successful collision refers to a collision between particles that results in a chemical reaction. In other words, it leads to the formation of new products.
b) An unsuccessful collision, also known as an ineffective collision, is a collision between particles that does not result in a chemical reaction. The particles simply bounce off each other without forming any new products.
3) Let's discuss why the reaction between magnesium and acid speeds up under different conditions:
a) When the concentration of the acid is doubled: Increasing the concentration of the acid means there are more acid particles present. As a result, the chances of a successful collision between the magnesium particles and the acid particles increase, leading to a faster reaction.
b) When the temperature is raised: Increasing the temperature provides more kinetic energy to the particles, making them move faster. This increased kinetic energy allows for more frequent and energetic collisions, increasing the likelihood of successful collisions and speeding up the reaction.
c) When the acid is stirred: Stirring the acid enhances the mixing of particles. By increasing the contact between the magnesium particles and the acid particles, stirring helps to increase the frequency of collisions, leading to a faster reaction.
d) When the metal is ground to a powder: Grinding the metal into a powder increases its surface area. This increased surface area exposes more metal particles to the acid, providing more opportunities for collisions between the magnesium particles and the acid particles. With a larger number of collisions occurring, the reaction speeds up.
