Answer:
The answer is " 10.39"
Explanation:
Calculating acid moles:
Calculating NaOH moles:
calculating excess in OH- Moles:
calculating total volume:
![[OH-]= \frac{0.000012} { 0.0472}](https://tex.z-dn.net/?f=%5BOH-%5D%3D%20%5Cfrac%7B0.000012%7D%20%7B%200.0472%7D)
= 3.6
= 10.39

Answer:
300
Explanation:
Multiply Length by value of 1000
Answer:
The answer is the explanation.
Explanation:
The acetic acid, CH3COOH, reacts with calcium hydroxide, Ca(OH)2, producing acetate ion, CH3COO- and water as follows:
2CH3COOH + Ca(OH)2 → 2CH3COO- + 2H2O + Ca²⁺
That means the moles of acetic acid decrease whereas the moles of acetate ion are increased. The ratio of [CH3COOH] / [CH3COO-] is different.
As a base is added, the concentration of H3O+ decreases increasing the pH.
That means:
<em>TRUE </em> A. The number of moles of CH3COOH will decrease.
<em>FALSE</em> B. The number of moles of CH3COO- will decrease.
<em>TRUE </em>C. The equilibrium concentration of H3O will decrease.
<em>FALSE </em>D. The pH will decrease.
<em>FALSE</em> E. The ratio of [CH3COOH] / [CH3COO-] will remain the same.
Answer:
They differ by their atomic mass and have same proton number.
Explanation:
Isotopes are atoms of the same element with the same proton or atomic number but with different atomic masses.
