The molarity of a solution prepared by diluting 25.71 mL of 0.0706 M ammonium sulfate to 500.00 mL is 0,0036M.

<h3>What is molarity?</h3>
  • Molar concentration, also known as molarity, quantity concentration, or substance concentration, is a unit used to describe the amount of a substance in a solution expressed as a percentage of its volume.
  • The number of moles per liter, denoted by the unit symbol mol/L or mol/dm3 in SI units, is the most often used unit denoting molarity in chemistry.
  • One mol/L of a solution's concentration is referred to as one molar, or 1 M.
<h3>What is the molarity unit in the SI?</h3>
  • The most common unit for molarity in chemistry is moles per liter, which is represented by the unit sign mol/L or moldm3 in SI units.

Phosphate buffers are commonly used in biological research. If a small amount of strong acid is added to a buffer solution that

Answer:

A) [H3PO4] will increase, [KH2PO4] will decrease, and pH will slightly decrease.

Explanation:

A buffer is a solution which resists changes to its pH when a small amount of acid or base is added to it.

Buffers consist of a weak acid (HA) and its conjugate base (A–) or a weak base and its conjugate acid. Weak acids and bases do not completely dissociate in water, and instead exist in solution as an equilibrium of dissociated and undissociated species. When a small quantity of a strong acid is added to a buffer solution, the conjugate base, A-, reacts with the hydrogen ions from the added acid to form the weak acid and a salt thereby removing the extra hydrogen ions from the solution and keeping the pH of the solution fairly constant. On the other hand, if a small quantity of a strong base is added to the buffer solution, the weak acid dissociates further to release hydrogen ions which then react with the hydroxide ions of the added base to form water and the conjugate base.

For example, if a small amount of strong acid is added to a buffer solution that is 0.700 M H3PO4 and 0.700 M KH2PO4, the following reaction is obtained:

KH₂PO₄ + H+ ----> K+ + H₃PO₄

Therefore, [H₃PO₄] will increase, [KH₂PO₄] will decrease, and pH will slightly decrease.:

What is the effect of increasing pressure on the equilibrium? N2 + 3H2 ⇔ 2NH3 a) Equilibrium shifts in forward direction. b) Equ
koban [17]

Answer:

a) Equilibrium shifts in forward direction.

Explanation:

If pressure is increased, equilibrium shifts to the side with the fewer moles of gas.

There are 4 moles of gas in the reactants and 2 moles of gas in the products.

The equilibrium will shift in the forward direction towards the products.

Hope that helps.

Why do the explosions get more violent the farther down the periodic table you go?
rewona [7]

Answer:

As we go down the group, the atom gets bigger. The bigger the atom, the further away the last electron. Therefore, the attraction between the nucleus and the last electron gets weaker. This makes it easier for the atom to give up the electron which increases its reactivity.
