Answer No 1:

The chemical model that is flawed is:

4 C2 + S8 → 4 CS2

In this reaction, there are more number of carbon atoms in the reactants but lesser number of cabon atoms in the products. For a reaction to be balanced, there should be the same number of atoms in the reactants and products. Hence, option A does not represent a balanced equation.

<em>Answer No 2:</em>

The correct option is B) The model shows an unbalanced number of carbon atoms.

Consider the equation:

4 C2 + S8 → 4 CS2

In the reactants side of the equation, there are 8 atoms of carbon. In the products side there are only four carbon atoms. This shows that this equation in not balanced because of the carbon atoms.

The number of sulfur atoms remains same before the reaction and after the reaction. There are eight sulfur atoms in the reactants as well as products.

Why do gases exert pressure?

lukranit [14]

Image result for why do gases exert pressure
The molecules are continually colliding with each other and with the walls of the container. When a molecule collides with the wall, they exert small force on the wall The pressure exerted by the gas is due to the sum of all these collision forces.The more particles that hit the walls, the higher the pressure.

Which hypothesis most likely inspired Leeuwenhoek's experimentation with new technology? If the amount of magnification is corre

Serjik [45]

Answer:

If the amount of magnification is correct, then an individual germ can be seen, because individual germs exist but are too small for human eyes.

Explanation:

<em>Leeuwenhoek was the first scientists to experiment with microorganisms using a self-designed single-lens microscope. He described the tiny organisms as 'animacules'. He is known for his pioneer work in the design of the first microscope.</em>

The microscope works by magnifying objects placed on the stage. Germs are microbes that cannot be seen with ordinary eye unless they are magnified appropriately. They are virtually everywhere, including the parts of the world where humans cannot survive.

Hence, the only correct option which most likely inspired Leeuwenhoek's experimentation with technology is the first option. The remaining options are deficient in some ways.
