Answer:
by providing an alternative pathway with a lower activation energy
Explanation:
Cataysts are the substances that neither consumed nor produced during a chemical reaction, but increase the rate of the reaction.
So, catalysts remain chemically unchnaged after the completion of the reaction.
For a reaction to occur, reactants molecule must collide and successful collisions lead to product formation.
A certain minimum amount of energy is required for successful collision. This minimum amounr of energy is called activation energy.
One way to increase speed of reaction is to provide energy to the reactants and other way to increase speed is to provide alternate pathway with lower activation energy.
Catalyst increases a rate of reaction by providing an alternate pathway with lower activation energy.
Therefore, the correct option is option b 'by providing an alternative pathway with a lower activation energy'
Biomass is organic, meaning it is made of material that comes from living organisms, such as plants and animals. Biomass<span> contains </span>energy<span> first derived from the sun: Plants absorb the sun's </span>energy through<span> photosynthesis.
Answer - photosynthesis</span>
An example is the cell theory
Answer:
No
Explanation:
The conclusions from Thomoson's claims would be invalid if his experiment could not be replicated.
<em>One of the attributes of a valid experiment in science is replication. That is, an experiment must be repeatable with similar outcomes under similar conditions as the original experiment when independently performed by another scientist. Once an experiment cannot be replicated, the outcomes of such an experiment become invalid in science.</em>
Hence, <u>Thomoson's conclusion would be invalid if his experiment could not be replicated. </u>
