Answer:
1. more slowly than
2. larger than
3. weaker
Explanation:
Acetone molecules are bonded by very weak intermolecular forces when compared to that of the hydrogen bond between water molecules. This makes it very easy for acetone molecules to vaporize easily into its gaseous state, much more faster than water molecules (since the acetone molecules need a lesser amount of energy to break these bonds). Also, the boiling point of liquid acetone is much lower than that of water, meaning that it has a higher vapor pressure than that of water.
Answer:
The contributions are not listed in the question. I guess the following are the options you are talking about.
Same elements have same properties:
In 1803 Dalton gave the atomic theory that the properties of the atoms of the same element are same.
Electrons in Orbits:
Electrons were discovered in 1897 by J J. Thompson but the hypothesis of electrons in the orbits were given by Hantaro Nagaoka in 1904.
Plum pudding model:
Plum pudding model was given by J. J. Thompson in 1904 with the concept of positively charged medium containing the negatively charged electrons in it.
Positively Charged Atomic Nucleus:
Earnest Rutherford in 1911 discovered the positively charged atomic nucleus.
The answer would be Propane. The formula for Propane is C3H8
Answer:
1. Svante Arrhenius
2. Johannes Nicolaus Brønsted and Thomas Martin Lowry
3. Gilbert N. Lewis
Explanation:
The scientist mentioned above researched and made their tested hypothesis available for further research to be built on them and they do these researches to help human understanding of the field and therefore improve knowledge.
Through their different definitions of acid which includes the ability of hydrogen ion (H+) to be produced when a substance is separated from water, the ability of acid to donate a proton (H +), It can be concluded that acids contain hydrogen and they have the ability to donate that (H +) to other substance.
