Cathode ray tube experiments

Chemistry
1 answer:
PilotLPTM [1.2K]3 years ago
6 0

Answer:

Particles of the cathode rays are fundamental to all matter.

Matter contains negative charge and by inference positive charge.

There are subatomic size particles in an atom.

Cathode rays have mass.

Explanation:

  • <u>Radiation emitted from cathode was accelerated toward the anode in tubes.</u>

This means that the cathode rays which are travelling towards anode (positively charged) are negatively charged. Atom was considered to have subatomic particles.

C and D are correct.

  • <u>Cathode rays was observed to be same regardless of composition of cathode.</u>

This means that particles of cathode rays are fundamental to all the matter.

A is correct.

  • <u>The rays are influenced by the magnetic and electric field and also they move a light fan when placed inside the tube. </u>

It means that the cahrged particle has mass too.

D is correct.

What mass of oxygen is needed to burn 4g of hydrogen, given the equation below
aleksandrvk [35]

32g of oxygen is required to burn 4g of hydrogen.

Define molecular mass.

A specific molecule's mass is expressed in daltons and is known as the molecular mass (m) (Da or u). Due to the varying isotopes of an element that they contain, multiple molecules of the same substance can have distinct molecular weights.

The total atomic mass of every atom in a molecule, calculated using a scale with hydrogen, carbon, nitrogen, and oxygen having atomic masses of 1, 12, 14, and 16, respectively. For instance, water has a molecular mass of 18 (2 + 16), which consists of two hydrogen atoms and one oxygen atom. known also as molecular weight.

In ,2H2+O2-----> 2H2O

H 2 molecules have a mass of 2 g/mol.

The molecular weight of oxygen is 32 g/mol.

When the chemical equation is balanced,

To totally react, 32 g of oxygen are needed for every 22=4 g of hydrogen.
