When the concentrations of CO2 and H2CO3 are both horizontal lines then the rate of the forward reaction is the same as the rate of the reverse reaction.
<h3>What is rate of reaction?</h3>
The term rate of reaction refers to how fast or slow a reaction proceeds. Recall that the rate of reaction is measured from the rate of disappearance of reactants or the rate of appearance of products.
When the [CO2] and [H2CO3 ] are both horizontal lines, the rate of the forward reaction is the same as the rate of the reverse reaction.
Let us recall that the reaction is reversible hence addition of H2CO3 will increase the concentration of H2CO3, the reverse reaction would be favored.

Answer:
Demonstration
Explanation:
The volcano model is just a demonstration of how an actual volcano looks like.
This is not an experiment.
- An experiment is a part of scientific method used to obtain data for the validation of a hypothesis.
- It is a very important part of any scientific investigation.
- Here since we are not looking for an answer to a problem, we are not dealing with an experiment.
- A demonstration is just a show off or a model to mimic the real world.
Answer:
Explanation:
There are principles that guides the distribution of electrons into the energy levels in an atom. Some of the principles are:
1. The maximum number of electrons in the orbitals of sublevels are:
2 electrons for s-sublevel with one orbital
6 for p-sublevel with 3 orbitals
10 for d- sublevel with 5 orbitals
14 for f-sublevel with 7 orbitals.
The maximum number of electrons in an orbital is 2.
2. Aufbau principle: it states that sublevels with lower energy are filled up before those with higher energy. Sublevels have pattern of filling.
3. Pauli exclusion principle: it states that no two electrons can have the same set of the four quantum numbers.
4. Hund's rule of maximum multiplicity: electrons goes into degenerate orbitals of sub-levels singly before pairing starts.
Hello!! WOW, what a coincidence! I just took this lesson and quiz yesterday, so the answer is still fresh in my mind!
The answer to your question is
D) Blowing sand can wear away a rock's surface and break it into smaller pieces
When wind blows, sure it can pick up dry soil and sand and relocate it, but that doesn't cause the weathering in rocks.
Wind doesn't create new landforms either, that comes from plate tectonic movements and other things.
I just eliminated B and C with the two sentences above, I really don't know how to eliminate A, just common sense i guess.
Please give me brainliest if I was correct and helpful!
Otherwise, please comment and let me know how I can fix my answer!
Thank you, it was fun, have a nice week!
