When a catalyst is involved in the collisionbetween the reactant molecules, less energy is required for the chemicalchange to take place, and hence more collisions have sufficient energy for reaction to occur. The reaction rate therefore increases. Collision theory is closely related to chemical kinetics
Answer:
The height = 39.44 m
Explanation:
Given:
Mass m = 2.5 kg
Potential energy = 986 J
Find:
The height
Computation:
Potential energy = mgh
g = Acceleration due to gravity = 10 m/s²
986 = (2.5)(10)(h)
h = 39.44 m
The height = 39.44 m
Answer:
Transitional metals are good conductors of both heat and electricity.
But since there aren't any. It could be Calcium.
Answer:
Explanation:
1:faringe:es un conducto que permite la comunicación entre las fosas nasales (el paso del aire por la nasofaringe a la laringe) y la cavidad bucal
Laringe:es una cavidad formada por cartílagos que presenta una saliente comúnmente llamada "nuez" en la laringe se encuentra las cuerdas vocales que al vibrar con el aire produce la voz
Tráquea:es un conducto de doce centímetros de longitud,situado delante del estómago.la tráquea brinda una vía abierta al aire que entra y sale se los pulmones
