Discovered the necleus
proposed the proton existence
discovered fusion reaction from fission
This is commonly true, but not always.
Answer:
Fe.
Explanation:
- The element which is oxidized is the element that losses electrons and its oxidation state be more positive.
- The element which is reduced is the element that gain electrons and its oxidation state be more negative.
<em> Fe goes from + 2 to +3, so, it is the element that is oxidized.</em>

Answer: Processes that change rocks from one type to another.
Explanation: During the rock cycle, different rock types change from one to another. For example, sedimentary rock changes to metamorphic rock through heat and pressure.
<h2>Answer:</h2>
6.67moles
<h2>Explanations:</h2>
Given the balanced chemical reaction between hydrogen and oxygen expressed as:

First, you need to calculate the moles of water produced.

Based on stochiometry, 2 moles of hydrogen produces 2 moles of water, hence the moles of hydrogen that will be needed to produce 120g of water is 6.67moles
