Dimensional analysis plconvert 19 inches to feet(show work)

19 in = 1.6 ft

You know that

12 in = 1 ft

If you divide both sides by 12 in, you get the conversion factor: 1 = 1 ft/12 in.

If you divide both sides by 1 ft, you get the conversion factor: 12 in/1 ft = 1.

Both are conversion factors because they both equal one and multiplying a measurement by one does not change its value.

You choose the conversion that gives you the correct dimensions for your answer. It must have the correct dimensions on top (in the numerator),

Thus, to convert 19 in to ft, you use the conversion factor with “ft” on the top.

∴ Length = 19 in × (1 ft/12 in) = 1.6 ft

b. acid is the correct answer @jayxboof all social media

acid : acids are those which accepts an electron-pairs.

base : bases are those which donates ab electron-pairs.

alkali : it is a base that dissolves in water. it is basically a base and the ph greater than 7.

hydroxide ion : it is a poly-atomic ion which is negatively charged.

oxygen, selenium, tellurium, and polonium.

they're all from the same group as sulfur (group 16).
