Molecules join together releasing photons, which realest heat and light. They do this until they work their way out of the sun
They perform cellular respiration
The first question the mass of Zinc would be 104g
152-64 =88
192-88=104
The second question the mass would be 159g
127+32 =159g
Answer:
6 C O 2 + 6 H 2 O + Δ → C 6 H 12 O 6 + 6 O 2
Explanation:
The Δ symbol denotes added energy, here in the form of sunlight. Strong C = O , and O − H bonds have been broken, and this bond cleavage is only partially energetically compensated by the formation of C − H and O = O bonds. Hence the reaction is endothermic (energy input on LHS). Note that the reaction is balanced with respect to mass and charge (says he, checking to see whether it is indeed balanced!).
