Ans: grinding one of the reactants into a powder.
this increases the surface area and hence there would be more chances of collisions happening. therefore reaction rate would increase
Answer:
-2, -1, 0, +1, +2
Explanation:
The quantum numbers describe the quantum state of an electron in an atom. These numbers are symbolized as n, l, m, and s. There are rules for the combination of these numbers. The angular quantum number (ℓ) is related to the magnetic number (<em>m</em>): if ℓ is equal to a number a, thus <em>m</em> can be any integer number between - a and +a.
According to this rule:
If ℓ = 2, thus <em>m</em> can be have a value of an integer between -2 and +2 ⇒ -2, -1, 0, +1, +2
Answer: You can increase the weight, then test the speed, and make the weight normal and test the speed, and mark which one travels faster.
Explanation: This would test your hypothesis by comparing the speeds of the cars when more mass is added. Calculating the difference of the speed with more mass, and the speed with normal mass would give you your answer. A positive number would prove your hypothesis and a negative number would disprove it.
Answer:
F i think i pretty sure F!!!!!!!!
Kinetic energy is energy that transfers energy by <span>net force which causes it to speed up and that causes more kinetic energy to be added . kinetic energy depends on mass and motion </span><span />
