Answer is A-photosystem II
The one in the middle since when ur going down it’s more quicker anc faster .
Answer:
See explanation
Explanation:
The reactivity of metals has a lot to do with their position in the electrochemical series. However, it is also known that metallic character decreases across the period. This implies that as we move from left to right along the periodic table. Sodium, magnesium, aluminum and silicon continues to decrease in metallic character. As a matter of fact, silicon is a metalloid and not a pure metal.
Sodium reacts with cold water to give a vigorous reaction,magnesium and aluminium reacts with steam at red heat.
Silicon does not react with water, even as steam, under normal conditions.
Because if the the technique is wrong the scientist is wrong I’m sorry it’s a bad answer :(
A catalyst speeds up the rate of reaction so the answer is B.
