A because b is for photosynthesis
For the first two
1. Will only give up one atom to be stable
2. Only 2 atoms
Answer:
Plantae. Plants are multicellular and most don't move, although gametes of some plants move using cilia or flagella. Organelles including nucleus, chloroplasts are present, and cell walls are present. Nutrients are acquired by photosynthesis (they all require sunlight).
<span>Electrons (negatively charged) are found in almost all the matter we see. They "buzz" around positively charged atomic nuclei; you may be familiar with one not-very-correct representation of an atom.
I hope helped ^-^</span>
Answer : The heat energy needed would be, 6486.5125 J
Explanation :
To calculate the change in temperature, we use the equation:

where,
q = heat needed = ?
m = mass of aluminum = 223 g
c = specific heat capacity of aluminum = 
= change in temperature
= initial temperature = 
= final temperature = 
Putting values in above equation, we get:


Therefore, the heat energy needed would be, 6486.5125 J
