What characterizes a system at equilibrium?

Chemistry
1 answer:
stira [4]3 years ago
5 0

Answer:

D. There is no net change to the system

Explanation:

Equilibrium means "equal". In a chemical system, changes occur in substances called the reactants to produce another substance called the products. These changes from reactants to products and vice versa occur at an uneven rate until EQUILIBRIUM is reached.

In other words, equilibrium is attained when the reactants and products are formed at an equal or constant rate i.e. There is no net change to the system. For example, in the chemical system below:

A + B ⇌ C + D

This system is said to be at "EQUILIBRIUM" if the rate of reaction of the reactants (A and B) is equal to that of the products (C and D). That is, there is no net change (difference) in the reaction rate.

The law of conservation of matter states that matter can be neither created nor destroyed. Your friend shows you the following c
WITCHER [35]

Answer:

According to conservation of matter, there should be equal amounts of all elements on both the reactant and product side.

Reactant:

1 Ca

1 C

1 O

Product:

1 Ca

1 C

3 O

Therefore, your friend is right because the law of conservation of matter is not followed in this chemical equation.

Why can you change physical properties and not make a new substance but can't change chemical properties and stay the same?
maxonik [38]

Answer:

Well this has a good chance of being wrong but i wanna say,

When you change a physical property of something it doesn't affect the chemicals that make it up. Like Ice, you can freeze water to make ice. You change a physical property (state of matter) but it's chemical properties don't change because in the end it's still water.

However if you remove a chemical property from something you are changing what made the new substance with will also change the substance along with it.

That's just what I think though

nasty-shy [4]

Answer:

Inflammation

Explanation:

Inflammation is the response to a cut. The blood vessels expand when you get cut to allow white blood cells to flock to the wound site. These attack any bacteria that got past the clot. If you mean <u>excess</u> bacteria, then that would be an infection.
