Answer:
When the two substances are mixed together, hydrogen ions in the vinegar react with the sodium and bicarbonate ions in the baking soda. This initial reaction results in two new chemicals: carbonic acid and sodium acetate. A decomposition reaction is the second reaction that occurs.
Both before and after the reaction, the mass is unchanged. Mixing vinegar with baking soda causes a chemical reaction. Carbon dioxide gas is one of the new chemicals that are created.
What is mass ?Mass is a physical body's total amount of matter. Inertia, or the body's resistance to acceleration when a net force is applied, is also measured by this term. The intensity of an object's gravitational pull to other bodies is also influenced by its mass. The kilogram is the primary mass unit in the SI.
A majority of an atom's mass is contained in its nucleus. For discussions of how atoms interact with one another and therefore for chemistry, biology, and electronics, the surrounding electrons are of course essential.
The hydrogen ions in the vinegar and sodium and bicarbonate ions in the baking soda interact when the two substances are combined. Carbonic acid and sodium acetate are the two new compounds produced by this first reaction.
Thus, According to the Law of Conservation of Mass, if the carbon dioxide gas is confined, the mass of the components will remain the same.

Scenario:Fossils show that many species, or kinds of organisms, have died out or become extinct because they could not respond to the pressures fast enough to survive. Those that did survive were better suited to their environment. Evidence shows that new species develop from old species as a result of gradual change. Natural selection is one process by which organisms change over time. Evidence shows that species change over time, sometimes giving rise to new species.External DataPrompt:Look at the pictures above that show how the giraffe got such a long neck. Write a scientific explanation of how natural selection applies to this process.

Why are lysosomes important?
When a cell is beyond repair, lysosomes help it to self-destruct in a process called apoptosis.
Answer: A lysosome is a membrane-bound cell organelle that contains digestive enzymes soooo. They break down excess or worn out cell parts, they may be used to destroy invading viruses and bacteria. If the cell is damaged beyond repair, lysosomes can help it to self-destruct in a process called programmed cell death, or apoptosis.

Use the proper grammatical format." I have no idea what to put down but I still wanted to get extra credit to help my grade a bit. (This is supposed to be Science- 7th grade, but I couldn't find the "Subject". Sorry)
Here's a rhyme about repetition I just made:
For accurate data, repeat and repeat,
so any inaccuracies will be beat!
Here's a rhyme about replication I just made:
Replication is important, so check your experiment.
When you replicate, with your results you'll feel confident!
