Answer:

The correct answer is "A buffer resists pH change by neutralizing added acids and bases".

Explanation:

In chemistry, a buffer is defined as an aquoeous solution that resist pH changes. Buffers are comprised of a weak acid (HA) and its conjugate base (A−) in an equilibrium relation, which results in the buffer neutralizing added acids and bases. Buffers play a crucial role in living beings since they provide a relative stable environment for the cells in what is known as homeostasis.

Answer:

A buffer resists pH change by neutralizing added acids and bases.

Explanation:

A buffer is an aqueous solution composed of two weak acids. False. A buffer is the mixture of a weak acid with its conjugate base or vice versa.

A buffer resists pH change by neutralizing added acids and bases. True. A buffer reacts with acid or base neutralizing, thus, pH change.

A buffer can absorb an unlimited amount of base. False. A buffer works just when ratio between substances in the mixture is 1:10.

A buffer does not change pH when strong acid is added. False. A buffer decreases change of pH by addition of acid or base but pH in a buffer change when acids are added.

I hope It helps!

28.7 l of propane, c3h8, are consumed in a combustion reaction. how many grams of water are produced?
lora16 [44]
The chemical reaction would be:

C3H8 + 5O2 = 3CO2 + 4H2O

For this case, we assume that gas is ideal thus in every 1 mol the volume would be 22.41 L. We calculate as follows:

28.7 L C3H8 ( 1 mol / 22.41 L ) ( 4 mol H2O / 1 mol C3H8 ) ( 18.02 g / mol ) = 92.31 g H2O produced

Hope this answers the question.

When comparing Potassium (K) and Calcium (Ca) you must compare?
Rom4ik [11]
Vitamin K and potassium are essential micronutrients the body needs to develop and function properly. The two share some things in common, but they’re not the same.

Each has a unique set of properties and purposes. Unlike vitamin K, potassium is not a vitamin. Rather, it’s a mineral.

On the periodic table, the chemical symbol for potassium is the letter K. Thus, people sometimes confuse potassium with vitamin K.

This article highlights some of the main similarities and differences between vitamin K and potassium.
