CO2(g) + H2O(I) - -> C6H12O6(s) + O2(g)
Lana71 [14]

Answer:

For instance equation C6H5C2H5 + O2 = C6H5OH + CO2 + H2O will not be balanced, but PhC2H5 + O2 = PhOH + CO2 + H2O will; Compound states [like (s) (aq) or (g)] are not required. If you do not know what products are enter reagents only and click 'Balance'. In many cases a complete equation will be suggested.

When trying to determine whether or not an atom gives up electrons easily, do chemists look at electronegativity or ionization p
Archy [21]
Here I found some info at Yahoo answers: https://answers.yahoo.com/question/index?qid=20090119191941AAB7oAb
The more electronegative an atom is the more unwilling it is to lose its electrons in a compound. If you do try to take a very EN atom away from a compound you'll need to apply a lot of energy for that to happen. I can give an example of a single atom though 

<span>Cl has 7 valence electron filled and every atom wants to be like nobles (noble gases), so it's not going to give an electron away b/c it's really close to being like a noble gas. Noble gases are the most stable atoms, which is why I say stability counts.</span>

Are s blocks metals ?
Mamont248 [21]
Yes, S-blocks are metals except for helium and hydrogen.  The S-block metals are shiny, silvery and relatively soft, although they can easily lose electrons.  Helium and hydrogen have valence electrons but also lack some similar properties as the other metals.
