Magnesium metal burns with a bright white flame. What conclusions can you draw about the electron transitions that can take place for a magnesium atom ?
The inference that can be made regarding the electronic transition that a magnesium atom is capable of experiencing is that the photons generated are not of a single wavelength.
What is metal?Metal is any of a group of substances with strong thermal and electrical conductivity, malleability, ductility, plus high light reflection.
The inference that can be made regarding the electronic transition that a magnesium atom is capable of experiencing is that the photons generated are not of a single wavelength, but rather are transitioned from several dissimilar levels to higher tiers, with several different wavelengths having joined to create white.
Therefore, the inference that can be made regarding the electronic transition that a magnesium atom is capable of experiencing is that the photons generated are not of a single wavelength.

Define, describe and give examples of Internal, External, and Behavioral adaptions.
Answer:
All organisms have adaptations that help them survive and thrive. Some adaptations are structural. Structural adaptations are physical features of an organism like the bill on a bird or the fur on a bear. Other adaptations are behavioral. Behavioral adaptations are the things organisms do to survive. For example, bird calls and migration are behavioral adaptations.
Adaptations are the result of evolution. Evolution is a change in a species over long periods of time.
Adaptations usually occur because a gene mutates or changes by accident! Some mutations can help an animal or plant survive better than others in the species without the mutation.
birdFor example, imagine a bird species. One day a bird is born with a beak that is longer than the beak of other birds in the species. The longer beak helps the bird catch more food. Because the bird can catch more food, it is healthier than the other birds, lives longer and breeds more. The bird passes the gene for a longer beak on to its offspring. They also live longer and have more offspring and the gene continues to be inherited generation after generation.
Eventually the longer beak can be found in all of the species. This doesn't happen overnight. It takes thousands of years for a mutation to be found in an entire species.
Over time, animals that are better adapted to their environment survive and breed. Animals that are not well adapted to an environment may not survive.
The characteristics that help a species survive in an environment are passed on to future generations. Those characteristics that don't help the species survive slowly disappear.

In an experiment, mixing baking soda and vinegar produced a combination of salty water and carbon dioxide shown in the following graph. What is the combined mass of the baking soda and vinegar before mixing?
45 grams
55 grams
35 grams
450 grams
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.

Geologists determine the hardness of a mineral using the Mohs scale of hardness. Why is it important for geologists to be able to do these tests in the field?
Answer:
To help determine what type of rock it is
Explanation:
Geologists can use information such as color, hardness, grain size, texture and other aspects of the rock to figure out the classification of a rock. for example, a light blue rock with no visible grain that is translucent and has a hardness of 9 is most likely going to be a saphire. hope this helps!!!!

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.
