A reaction is most likely to occur when the colliding particles have proper orientation and energy.
Reactions occur when two reactant molecules effectively collide, each having minimum energy and correct orientation. According to the collision theory of reactivity, reactions occur when reactant molecules "effectively collide. For an effective collision to occur, the reactant molecules must be oriented in space correctly to facilitate the breaking and forming of bonds and the rearrangement of atoms that result in the formation of product molecules.
Answer:
An increase in temperature indicates that the molecules of gas speed up.
Explanation:
The molecular kinetic theory states that the average kinetic energy of gas particles (molecules) is proportional to the absolute (Kelvin) temperature of the gas, and all gases at the same temperature have the same average kinetic energy.
Therefore, as the temperature increases so the kinetic energy increases.
It is also known that the kinetic energy is proportional to the squared speed of the particles, therefore the higher the kinetic energy the average speed of the molecules:
- higher temperature → higher kinetic energy → higher average speed
Answer: The equation would be easiest to use to find the new volume of the balloon is
Explanation:
To calculate the final temperature of the system, we use the equation given by Charles' Law. This law states that volume of the gas is directly proportional to the temperature of the gas at constant pressure.
Mathematically,
where,
are the initial volume and temperature of the gas.
are the final volume and temperature of the gas.
We are given:
Putting values in above equation, we get:
The equation would be easiest to use to find the new volume of the
balloon is
Answer: A. Metalloids exhibit properties of both metals and nonmetals
Explanation: Metalloids are elements that has a metallic appearance such as shiny, dull amd ductile but they possess the properties of nonmetals in which they are intermediately poor conductors of heat and electricity in which they are good semiconductors.
