Question

Which of the following is an advance in technology that has helped us to increase environmental quality?

diluting fertilizers by over-watering farmland

using biological organisms to clear up polluted water

heating water to kill excess bacteria in aquatic ecosystems

burning garbage to reduce the amount of waste in landfills

Answer 1

B? @aaronq only one that seems plausible imo

Answer 2

most definitely

Answer 3

mind checking a few others that i think i know but not sure about?

Answer 4

yeah no problem

Answer 5

What is the primary reason fusion is not used in power plants?

Fusion causes too much air pollution.

Fission generates more energy than fusion.

The cost of using fusion in a practical way is too high.

Current technology is unable to control the reaction.

Answer 6

Either c or d

Answer 7

i'm pretty sure it's D

Answer 8

ok, i was leaning towards c because i thought we're able to control it but it's to expensive atm :p

Answer 9

oh okay, well there you go! haha i've honestly only studied nuclear chemistry in highschool, so that's definitely one of my weaknesses

Answer 10

I guess it says 'practical way' though and we're not really using efficiently yet. and they haven't really covered much of this stuff at all

Answer 11

All of the following can be recycled except

clothing.

aluminum cans.

compact fluorescent bulbs.

plastic drink bottles.

i thought we could recycle all of these and the lesson doesn't specify .-.

Answer 12

light bulbs made out of glass so we can recycle that, we can recycle aluminum. i'm guessing clothing

Answer 13

hmm i would go with clothing, but i imagine that there are ways to recycle that too

Answer 14

dumb questions

When fast moving electrons are released from an atom by way of a beta particle, the atom ends up with

one less proton and one more neutron.

one more proton and one less neutron.

the same number of protons and two more neutrons.

two more neutrons and the same number of protons.

i think this is the last one

Answer 15

\(\beta\) decay increases the number of protons by 1 and decreases the number of neutrons by 1

Answer 16

i looked this up because, again, nuclear chemistry is pretty foreign to me

Answer 17

ok that's fine. thanks!
