The phrase which best describes nuclear fusion is: A. the process by which small nuclei combine into a larger nucleus.
A nuclear reaction can be defined as a type of chemical reaction in which the nucleus of an atom of a radioactive chemical element is transformed by either being joined (fusion) or split (fission) with the nucleus of another atom of a radioactive chemical element and accompanied by a release of energy.
Generally, there are two (2) main types of nuclear reaction and these include:
- <u>Nuclear fission:</u> it involves the collision of a heavy atomic nucleus with a neutron, thereby causing a split and release of energy.
- <u>Nuclear fusion:</u> it involves the joining of two smaller nuclei of atoms to form a single massive or heavier (larger) nucleus with the release of energy.
In conclusion, nuclear fusion is best described as the process by which small nuclei combine into a larger nucleus, accompanied by a release of energy.

Answer:
Actually, one of the more interesting organisms at those depths is the Xenophyophore, a creature which, despite being single-celled, can grow to be over 10 centimeters wide. "Scientists say xenophyophores are the largest individual cells in existence.

So we know the number of moles of each compound. If we need to know the concentration we must know the number of moles that the compounds react with...
        
                    
             
        
        
        
Answer:
 CH₂
Explanation:
Given parameters: 
Percentage composition: 
           Carbon  = 40.1% 
           Hydrogen  = 6.6% 
Unknown: 
Empirical formula of the compound  = ? 
Solution: 
The empirical formula of a substance is its simplest formula. 
  Elements                             Carbon                             Hydrogen 
Percentage 
Composition                           40.1                                     6.6 
Molecular mass                        12                                         1 
Number of moles                  40.1/12                                  6.6/1 
                                                 3.342                                    6.6
Divide through by 
the smallest                         3.342/3.342                           6.6/3.342
                                                       1                                        2 
So the empirical formula of the compound is CH₂
