Why does platinum metal make a good catalytic surface for reactant molecules? it causes reactant molecules to be less reactive. it strengthens bonds between reactant molecules. it prevents products from breaking away from the surface. it holds reactant molecules in a good position for them to react.

The right answer is "It holds reactant molecules in a good position for them to react."

Explanation:

Catalysts are a substances that increase the reaction rate by lowering the activation energy (Eₐ) by providing an alternative (lower-energy) pathway for the reaction to take place .

The catalyst increases the frequency of collisions between reactants this done by holding reactant molecules in a good position for them to react.

So, The right answer is "It holds reactant molecules in a good position for them to react."

plants need sunlight, water, and carbon dioxide to make food. plants use the raw materials of water, nutrients they absorb from soil, and carbon dioxide to make sugars the plant can use. energy from the sun and chlorophyll are also needed.

8 m/s because for him to get the same amount of energy as ray is putting out, bobby, who weighs half as much as ray, needs to run twice as fast.
