Answer:
Follows are the matching to this question:
Explanation:
Column A Column B
1 c
2 d
3 b
4 a
Description of the matching:
- In 1(Acid) the correct choice is (c) because the acid (HCl) dissociates to both the H+ ion and the Cl- ion as a solution.
- In 2(Alkaline ) the correct choice is (d) because alkaline NaOH is a solution that differentiates between the ions ( OH-) and Na+.
- In 3(pH ) the correct choice is (b) because for an A compound of less than 7 is an acid and an alkaline pH compound of more than 7. For neutral compounds, a pH of 7 is applicable.
- In 4(Ion) the correct choice is (a) because Na+ ion is loaded positive, and Cl-ion is loaded negatively.

print("A")
elif grade > 70 and grade < 80:
print("B")
elif grade > 60 and grade < 70:
print("C")
elif grade > 40 and grade < 50:

Explanation:
<span>In certain instances, it makes sense to print documents in landscape orientation. Some examples include spreadsheets and tables, where the content within the document is wider than it is longer. If you print in portrait mode, it would cut off parts of the table or spreadsheet. In this case, you'll want to change the print settings to landscape. To change it to landscape, simply click the "landscape" button on the print preview tab.</span>
Blogs, even academic and professional, are not usually considered reliable sources. Most importantly, that's because they don't undergo the peer review process, which ensures the quality of the published papers (that they don't publish lies, in simple words).
So usually, you would prefer a published paper.
When then would you use a blog?
One such instance is when you want to find out about a quickly changing field , for example the newest standards in software development. So software engineering is one such field.
Another field is internet protection and security, as the viruses and the ways to defend against them also develop faster than can be published in a paper
