Question

1. what factors affect the rate of a chemical reaction or dissolving? particle size color of reactants stirring temperature concentration 5. when evaluating a device designed to minimize net force during collisions, what concepts of physics would be applied? impulse chemical reactions momentum electrical circuits photosynthesis

Explanation:

• For the first question, particle size affects the surface - area to volume ratio and reaction rate, stirring increases the contact between reactants, temperature affects the kinetic energy of particles, and concentration affects the frequency of collisions. Color of reactants has no impact on reaction rate.
• For the second question, impulse ($J = F_{net}\Delta t$) and momentum ($p = mv$) are related to forces in collisions. Chemical reactions, electrical circuits, and photosynthesis are not relevant to minimizing net - force in collisions.

Answer:

1. Particle size, Stirring, Temperature, Concentration
2. Impulse, Momentum
