What is the weakness of particle theory?

Answers

Answer:

The particle model does not take into account: the size and shape of particles. the space between particles.

The weakness of particle theory are:

matter is very small in size which are continuously moving. most of the particle are not spherical.particles are not solid because atoms are having empty space.What is particle theory?

it is a part of kinetic theory which states that all matter consists of very small particles which are constantly moving or in a continual state of motion.

Therefore,  lack of space between particles and size of particles are the limitations of particle theory.

please answer this no links please!!

Answers

Based on the nature of the types of chemical bonding, the example illustrates covalent bonding because electrons are shared between the carbon and hydrogen atoms.

Chemical bonding

Chemical bonding or combination occurs when atoms of elements combine to form products.

Chemical bonding can either be;

ionic bonding orcovalent bonding

Covalent bonding

Covalent bonding involves a sharing of electrons by the atoms of elements involved.

Since the example shows electrons being shared between carbon and hydrogen atoms, the example illustrates a covalent bonding because electrons are shared between the atoms.

How can you identify the gas produced in a chemical reaction without observing the atoms and molecules directly?

Answers

To identify the gas produced in a chemical reaction without observing the atoms and molecules directly through the characteristics of the gas.

Chemical reaction is defined as the process by which substances (known as reactants) combine together with the formation of bonds to form products.

There are some signs that shows that chemical reaction has occurred. They include:

Color Change Change of temperatureGiving off gas (Evolution of gas)

Therefore, the production of gas from a chemical reaction shows that a reaction has occurred.

These gases can be identified without observing the molecules through that characteristics of the gas. This include:

the smell of the gas: For example when a gas is given off, and it smells like urine, it's likely to be ammonia gas. color change that occurs during the chemical reaction can show the type of gas that was given off. For example when lime water turns into milky color, it shows the presence of carbondioxide gas.
