D, 2Cu + O2 → 2CuO. A is wrong because oxygen is a diatomic element, meaning it always has to come in the form of O2 in the case of gas. B is wrong because the equation isn't balanced correctly; there's two oxygens on the reactants side, while only one oxygen on the products side. C is wrong because it's saying you're STARTING OUT with CuO already: that doesn't correspond with the word problem. Thus leaves D, where the equation is balanced correctly, has the diatomic oxygen, and ends with CuO.
Answer:
The structure is shown in the figure.
Explanation:
There is condensation polymersiation in case of lactic acid with the removal of water molecule (dehydration) leading to formation of poly lactic acid.
The structure of PLA is shown in the figure.
N= g/m therefore g=n*m so you do...
G = 6 * (Molar mass of H2O )
G = 6 * (1.01 x 2)+(16)
G = 6 * (18.02)
G = 108.12 grams of H2O
