Producing nuclear energy is far more environmentally friendly than burning fossil fuels. That is the main benefit.
The main risk is radiation. If the nuclear waste is not properly disposed of, it can leak radiation into the environment. Fortunately, this is not an issue since there are ways to deal with it. There is also the risk of a disaster like the Chernobyl incident, however that was mostly due to faulty reactor construction. However, reactors today are built to avoid such issues.
Answer:1.47
Explanation:
I got it correct on accelus
Ohm’s Law states that electrical current is proportional to voltage and therefore inversely proportional to resistance - V = I x R
light waves slow down as they travel from the air through the water
Answer:
15 kJ
Explanation:
We need to know the following;
what is activation energy?
- Activation energy is the minimum energy required by reactants for a chemical reaction to take place.
What are catalysts?
- Catalysts are molecules or substances that speed up the rate of a chemical reaction.
- In other words, catalysts increase the speed at which products are formed from reactants.
How do catalysts speed up reactions?
- Catalysts speed the rate of chemical reactions by lowering the activation energy of the reactants.
- When activation energy is lowered, reactants require less energy for the reaction to occur which easily achieved making the reaction proceed faster.
- Therefore, in presence of a catalyst, the new activation energy should be lower than the initial value of activation energy.
