The compound ch3ch2-sh is in the organic family know as c. thiols
A homogenous mixture is uniform and thus hard to recognize as a mixture. An example is water.
No. It's a phase change, and all phase changes are physical
Answer:
The answer to your question is: letter A
Explanation:
a) A + B ⇒ AB + heat It is an exothermic reaction because heat is released.
b) A + BΔ ⇒ AB It heat added to the reactants , then it is an endothermic reaction.
c) heat + BC ⇒ B + C It's an endothermic reaction because heat is added to the reactants.
d) B + heat + CD ⇒ BD + C It's and endothermic reaction because heat is added to the reactants.
Answer:
Answer is in the explanation.
Explanation:
Before the equivalence point, the pH of the solution of HCl that is titrated with NaOH has a pH <<< 7. When you are adding more NaOH nearing, thus, to the equivalence point the change in pH occurs quickly, and, with 1 drop of excess of NaOH after equivalence, the pH of the solution change to a pH >>> 7
That means the volume added at pH 5 or pH 9 is, almost, the same doing the indicator work just as well as an indicator with change color at pH 7
