100 points! why does the author present redi’s experiments first, followed by pasteur’s experiments? redi’s experiments were more important than pasteur’s. the author wanted to present the experiments in historical sequence. redi’s experiments completely changed the belief in spontaneous generation. the author wanted to focus on the maggots that were found in the rotted meat.

The correct answer is B because Redi's experiment was done in 1668, and Pasteurs experiment was to prove redis and he did his in 1860!

Hi,

B) The author wanted to present the experiments in historical sequence

My work: Redi out his experiments in a time line.

Extra information: Redi came up a hypothesis that maggots spontaneously just appeared, and showed up in rotten meat. He was then disapproved.

I Hope I Helped!

i believe it is a.) released into

explanation:

1. for the first question, we must find the mass of the anhydrous salt, mgso₄. the molar mass for mgso₄·7h₂o is 246.47 g/mol, while that of mgso₄ is 120.37 g/mol.7.834 g mgso₄·7h₂o * 1 mol mgso₄·7h₂o/246.47 g * 1 mol mgso₄/1 mol mgso₄·7h₂o * 20.37 g mgso₄/mol = 0.647 g mgso₄

2. mass of water = mass of sample - mass of anhydrous salemass of water = 7.834 - 0.647 = 7.19 gpercent water in hydrate = 7.19/7.834 * 100 = 91.74%
