The plum pudding model of the
atom by the scientist Sir Joseph John Thompson or J.J. Thompson. It was
theorized after the discovery that electrons are present in the atom. In this
model, the atom is composed mainly of electrons. It was describe as plum
pudding because the electrons are dispersed within the atom. John Dalton
discovered the atom. Ernest Rutherford discovered the half – life of an atom
and Neils Bohr explain the quantum mechanics. So the answer is J.J. Thompson.
Answer:
c. Three fatty acid chains and a 'backbone' of glycerol
Explanation:
A triglyceride is ester which is derived from glycerol and three (may be different or same) fatty acids. The name is thus derived as tri ( 3 fatty acids) - and glyceride (glycerol backbone). Triglycerides are main constituents of the body fat in human body and other vertebrates.
<u>Triglycerides are the tri-esters which consist of glycerol attached to 3 molecules of fatty acid.</u> Alcohols consists of hydroxyl group. Organic acids consists of carboxyl group. Alcohols and organic acids join to form esters. <u>The molecule of glycerol has 3 hydroxyl groups which are bonded to three fatty acid molecules via ester bonds.</u>
The formula for phosphorus is P4
Answer : It will take 366 minutes to fill 1.00 gallon bucket.
Explanation :
We have been given the drip rate which is 41 drops/min
Let us use this as a conversion factor to ind out the minutes taken to fill 1 gal bucket. We will arrange this conversion factor in such way that , "drops" would get cancelled.
They have also given us that 1 gallon bucket contains 15000 drops.
The equation can be set up as follows.
It will take 366 minutes to fill 1.00 gal bucket.
