decide how to supersets these substances? If if is not possible, please write "cannot be separated" on the space provided​

Answer: (although the question does not sate whether if you separate them physically or through energy. so i did both)

1. can be separated (When high-energy ultraviolet rays strike ordinary oxygen molecules (O2), they split the molecule into two single oxygen atoms, known as atomic oxygen)

2. can be separated, but through electrolysis, fiscally moving a crane to generate electricity to separate the molecules

3. Most solid particles, composed of diamagnetic or weak paramagnetic materials, cannot be extracted by a conventional magnetic separator. physically cannot be separated. but through heat yes

4. but there is a catch: doing so requires energy. ... If energy from coal were applied to drive the decomposition reaction, more CO2 would be released than consumed, because no process is perfectly efficient. so it cant be separated physically

5. it can be separated but it needs energy physically cannot be separated.

Explanation:

Which statement best explains how the conditions identified in Part A affect the availability of opal?​
A
Weathering processes no longer occur in Australia, so no new opal is formed.
B
Gems do not need an exact combination of elements or minerals to form, so opal forms more easily.
C
Opal formation occurs over large periods of time, so the number of opal deposits is limited.
D
Volcanoes in Australia no longer provide high temperatures and pressures, so no new opal is formed.

Two reactant particles collide with proper orientation. The collision will be
effective if the particles have
(A) sufficient potential energy
(B) high activation energy
(C) high ionization energy
(D) sufficient kinetic energy
And explain why

Use the kinetic energy equation to explain why speed has a greater impact on kinetic energy than mass.​

The Concrete that surrounds a swimming pool takes less time to heat up than the water in the pool. Why

SEP Design a Solution A simple bread recipe calls for 400 g of flour, 7 g of salt
(NaCl), 1 g of yeast, and 0.3 L of water (H2O). You have exactly 0.6 mol of salt. If
you want to use all of the salt, how many loaves of bread could you make? How
much of each of the other ingredients would you need?

The Himalayan balsam plant makes seeds in pods and releases them when it is ready, while the Surinam toad absorbs its eggs into its own back until they are ready to come out. How are the adaptations of the balsam and the toad similar?

A: They are behaviors that allow the plant and the animal to reproduce through shorter life cycles.

B: They are behaviors that protect the plant and the animal from predators.

C: They are life cycle differences that protect the offspring and help them to survive.

D: They are physical characteristics that allow the offspring to survive in cold weather conditions.
