A loose, icy body with a long, narrow orbit is a comet
Scientists often communicate their research results in three general ways. but this only asks for 2 so I'm giving 2 haah anyway .One is to publish their results in peer reviewed journals that can be ready by other scientists. Two is to present their results at national and international conferences where other scientists can listen to there presentations or presentations in general.
hope this helped
Answer:
its the 3rd option.
the molecules move from region of higher concentration to a region of lower concentration.
Explanation:
please do give me brainliest if this helped you.
thank you and have a great day :D
Density = mass/volume
Density = 81g/0.9cm³
Density = 90g/cm³

In buffer solution there is an equilibrium between the acid HA and its conjugate base A⁻: HA(aq) ⇌ H⁺(aq) + A⁻(aq).
When acid (H⁺ ions) is added to the buffer solution, the equilibrium is shifted to the left, because conjugate base (A⁻) reacts with hydrogen cations from added acid, according to Le Chatelier's principle: H⁺(aq) + A⁻(aq) ⇄ HA(aq). So, the conjugate base (A⁻) consumes some hydrogen cations and pH is not decreasing (less H⁺ ions, higher pH of solution).
A buffer can be defined as a substance that prevents the pH of a solution from changing by either releasing or absorbing H⁺ in a solution.
Buffer is a solution that can resist pH change upon the addition of an acidic or basic components and it is able to neutralize small amounts of added acid or base, pH of the solution is relatively stable
