I will help you with answering this question.
There are two kinds of analysis: qualitative and quantitative
In quantitative we analyse the amount of something that is how much of something is present / the quantity. Ex: the length of branch of tree, number of students in class, volume of a liquid in a beaker.
In qualitative analysis we determine the kind of substance / quality of substance / nature of substance.
like: colour of a substance, odor of a substance or taste (bitter / sour / sweet etc) of a substance
So answer is : B.The substance tastes bitter
Explanation:
1 is a process that occurs when gases in earth's atmosphere trap the sun's heat .
2 . heat in the atmosphere to warm the planet .
I only know the first too sorry ✨
Answer:
This is a basic solution
Explanation:
To be able to provide a succint description of this solution, from the given parameters we can deduce the pH of the solution.
Given parameters:
Concentration of OH⁻ = 1 x 10⁻⁴M
Solution
We knonw that pOH = -log₁₀[OH⁻]
pOH = -log₁₀ 0.0001 = - (-4) = 4
For an aqeous solution:
pH + pOH = 14
pH = 14 - 4 = 10
The pH of the solution has been derieved to be 10
This is a basic solution
