How do the central ideas of the destruction of the past and survival in the present interact within the text? the poet gives examples of how the past is preserved through memories, monuments, or transformations. the poet judges that all that was good and decent in the past has been completely destroyed. the poet alludes to the total destruction of the universe with his reference to hiroshima and the dropping of the nuclear bomb. the poet creates images to suggest humans and animals all face the same mortality.

the old alchemists made significant contributions to science even though there starting premises were off a bit. their conclusions after failure would steer them into better directions for investigation. science is no more than close observation and the initial mistakes result in rethinking and retrying experiments.

you need to take a look at the periodic system in order to sort these elements into pairs that would most likely exhibit similar chemical properties. first, you need to find elements that are found in the same group (groups are vertical in the periodic system), and then to see whether they have the same valence number. if they meet these criteria, they will have similar properties.

the first pair: ne (neon) and kr (krypton), are noble gases found in group 8

the second pair: li (lithium) and k (potassium), found in group 1

the third pair: s (sulfur) and te (tellurium), found in group 6

answer: mole of the gas

answer: mole of the gasexplanation:
