Why did the better part of century pass between Thompson’s work and Dalton’s work

Chemistry

melisa1 [442]3 years ago
6 0
I would say the correct answer would probably be that to explain the approx 100 years between Dalton (early 1800's) atomic theory and JJ Thomson's discovery of the smaller particle the electron was that Thomson had the use of a cathode ray tube that helped to determine the existence of negatively charged particles about 2000 times lighter than a hydrogen atom and therefore a smaller particle than the atom. The cathode ray tube was not invented until 1897, when Thomson began experimenting with it.

Which conversion factor is needed to solve the following problem?
USPshnik [31]
Molar Volume is required to solve this problem. As we know that "1 mole of any gas at standard temperature and pressure occupies 22.4 L of volume". SO using this concept, we can calculate the volume of ammonia formed by reacting 54.1 L of Hydrogen gas as follow,

Match the name of each gas law to the properties it compares. 1. Gay-Lussac's law 2. Boyle's law 3. Avogadro's law a. Volume and
oee [108]

Answer:

1. C    2. B     3.  A

Explanation:

1. Gay- Lussac law, states that as along as the volume is kept constant, the      pressure of a fixed mass of gas is directly proportional to the temperature.

The properties it compares is; (c.) Pressure and temperature

2.  Boyle's Law states that; as long as the temperature is kept constant, the volume of a fixed mass of gas is inversely proportional to the pressure.

It therefore compares; (b.) Pressure and volume

3. Avogadro's Law states that equal volumes of different gases contain the same number of molecules provided the temperature and pressure are the same.

It therefore compares;  (a.) Volume and moles

Which statements are inconsistent with dalton's atomic theory as it was originally stated?
Blababa [14]

Missing question:

A. All carbon atoms are identical.

B. An oxygen atom combines with 1.5 hydrogen atoms to form a water molecule.

C. Two oxygen atoms combine with a carbon atom to form a carbon dioxide molecule.

D. The formation of a compound often involves the destruction of one or more atoms.

Answer is: B and D.

A is correct because Daltan stated: All atoms of a given element have the same mass and other properties that distinguish them from the atoms of other elements.

C is correct because atoms combine in simple, whole- number ratios to form compounds, B is incorrect because ratio is not simple, whole number.

D is incorrect because according to Dalton. atoms can't be created or destroyed.
