Answer:

C. submicroscopic

Explanation:

I am not sure but I think the best answer here is C, because "submicroscopic" means "too small to be seen by an ordinary light microscope". And because the name of this aparatus sounds so specifically, the answer B - microscopic - not seems to be the best.

"Scanning Tunnelling Microscopy" (STM) is a technique that has been used for the surface study of NANOSTRUCTURES using the chemical composition of atoms and molecules in NPs to image surfaces at atomic level. - This is the definition of STM. It includes the word NANOSTRUCTURES, so the answer C must be the best one.

HELP!!!!!
faltersainse [42]

Answer:

5.17.

Explanation:

<em>∵ [H₃O⁺][OH⁻] = 10⁻¹⁴. </em>

[OH⁻] = 1.5  x 10⁻⁹ M.

∴ [H₃O⁺] = 10⁻¹⁴/[OH⁻] = 10⁻¹⁴/(1.5  x 10⁻⁹ M) = 6.66 × 10⁻⁶ M.

∵ pH = - log[H₃O⁺]

<em>∴ pH = - log(6.66 × 10⁻⁶ M) = 5.17. </em>

Suppose a friend says that we don't need to worry about the rising temperatures associated with global climate change. Her claim
ludmilkaskok [199]

Answer:

Carbonic acid could be formed.

Explanation:

Hello,

Based on her claim, it would be a really useful strategy to prevent global warming, nevertheless, there would be a problem if a increasing amount of carbon dioxide is not buried at the bottom of the ocean yet it flows freely along the sea and probably reacting with the water, causing carbonic acid to be formed  and subsequently cutting back the sea's pH (increasing its acidity).

It would be useful, but a constant monitoring of the sea's pH must be needed because this could cause some species to be affected not only by the temperature but for the acid pH as well.

Best regards.
