Answer:
h B i f M r
Explanation:
that was just my estimated guess but it seems right to me
A.glucose is a product of the photosynthesis reaction carbon dioxide is a reactant.
A and C are incorrect because they are not complete transfer of valence electrons. Ionic bonds best to form a neutral molecule
Cao + H2O ---->Ca(OH)2
Calculate the number of each reactant and the moles of the product
that is
moles = mass/molar mass
The moles of CaO= 56.08g/ 56.08g/mol(molar mass of Cao)= 1mole
the moles of water= 36.04 g/18 g/mol= 2.002moles
The moles of Ca (OH)2=74.10g/74.093g/mol= 1mole
The mass of differences of reactant and product can be therefore
explained as
1 mole of Cao reacted completely with 1 mole H2O to produce 1 mole of Ca(OH)2. The mass of water was in excess while that of CaO was limited
Spent fuel that can no longer be used to create energy is waste.
