Answer:
The purpose of a hypothesis is to find the answer to a question. A formalized hypothesis will force you to think about what results you should look for in an experiment.
Explanation:
Hope this is helpful to you!
Answer:
Chloride (Cl⁻) and sodium (Na⁺) ions.
Explanation:
Hello,
In this case, since the aqueous species are actually dissociated when reacting and the solid species (ferric carbonate) remains undissolved, we can modify the given reaction as follows:
In such a way, dissociating the aqueous species we obtain:
It means that the net ionic equation is:
Therefore, the spectator ions are those were cancelled out, chloride (Cl⁻) and sodium (Na⁺).
Best regards.
Answer: a) pH of a 0.1 M vinegar solution is 2.9
b) It is an acid as pH is less than 7
Explanation:
pH or pOH is the measure of acidity or alkalinity of a solution.
pH is calculated by taking negative logarithm of hydrogen ion concentration.
Acids have pH ranging from 1 to 6.9, bases have pH ranging from 7.1 to 14 and neutral solutions have pH equal to 7.
As vinegar is a weak acid, its dissociation is represented as;
cM 0 0
So dissociation constant will be:
Give c= 0.1 M
Also
Thus pH of a 0.1 M vinegar solution is 2.9
As pH is less than 7, it is an acid.
A: Some ice will turn into liquid water.
