The functional groups are written in the pictures attached. The first picture is aspirin. The functional groups are carboxylic group(O=COH), ester (O=COR), and aromatic group (benzene ring), where R is any hydrocarbon chain. The second picture is acetaminophen. The functional groups are amide group (O=CNHR), hydroxyl group (ROH) and aromatic group (benzene ring).
Answer:
D or the 4th one
Explanation:
mass is literally the measure of matter in an object which is essentially the weight or how much stuff there is.
Answer:
Explanation:
You have the equation. Now change the 3.4 g H2 to moles. moles = grams/molar mass
<em>3.4 g/2.016 = 1.686 moles.</em>
Now using the coefficients in the balanced equation, convert moles H2O2 to moles H2O.
1.686 moles H2 x (2 moles H2O/2 moles H2O2) = 1.686 x (2/2) = 1.686 x (1/1) = 1.686 moles H2O.
Now you know that 1 mole of water is composed of 6.022 x 10^23 molecules. So
1.686 moles H2O x (6.022 x 10^23 molecules H2O/1 mole H2O) = ?? molecules.
Cool liquid from 314 K to 273 K, freeze liquid at 273 K, and cool solid to 263 K.
