Shift to reactants(left)

A buffer solution is a solution that can maintain a good pH value due to the addition of a little acid or a little base or dilution.
The buffer solution can be acidic or basic
Acid buffer solutions consist of weak acids and their salts.
A buffer solution of NaC2H202 and HC2H2O2 (acetic acid) is included in the acid buffer
So :
a slight addition of acid (H⁺) will be balanced by the conjugate base
the addition of a small base (OH⁻) will be balanced by the weak acid
With the addition of acid (H +), the equilibrium will shift to the left, in the formation of CH3COOH. The added acid will be neutralized by the conjugate base component (CH3COO−).
Answer:The molecules in a raw egg absorb the heat energy, they use this energy to change shape
Such a chemical reaction is said to be endergonic, which means 'energy in'.
Egg molecules will never undergo these reactions without the input of energy (usually in the form of heat)
I hope this helps, if not, let me know :)
Since power, P, equals iV, P/V = i, so at 120 V, a 40-watt bulb draws 1/3 A.
It is Titration (when you adding ,for example, acid to base)
Answer:
18.81 g
Explanation:
We are given;
- Volume of Barium nitrate as 21.29 mL or 0.02129 L
- Molarity of Barium nitrate as 3.38 M
We are required to determine the mass of Barium nitrate
Step 1: Determine the number of moles of Barium nitrate
Number of moles = Molarity × Volume
= 3.38 M × 0.02129 L
= 0.07196 moles
Step 2: Determine the mass of Barium nitrate
We know that;
Mass = Number of moles × Molar mass
Molar mass of Barium Nitrate is 261.337 g/mol
Therefore;
Mass of barium nitrate = 0.07196 moles × 261.337 g/mol
= 18.8058 g
= 18.81 g
Thus, the mass of barium nitrate dissolved is 18.81 g
