Is this a scientific model? Use complete sentences to explain why or why not.
Answer:
its a scientific model
Explanation:
It is a scientific model because it is showing the water cycle. In the water cycle it is scientifically showing how water circulates through the Earth. For example, the water in the ocean evaporates which is evaporation, then it condensates into a cloud that then becomes condensation and the condensation makes precipitation when it rains. When it falls to the ground, it then becomes a runoff down a hill.
What happens when water turn’s into gas
Answer:
The process of turning water into gas is called evaporation. When water is heated, it changes state from a liquid to a solid. No mass is destroyed during the process, but rather, it is converted into gas.

Stereoisomers share the same connectivity and differ only in the way their atoms are arranged in space. Draw the structure of a compound that is a stereoisomer of trans-1,2-dibromocyclobutane.(Note that the question asks for a different stereoisomer of the named compound and not the named compound itself.)Use the wedge/hash bond tools to indicate stereochemistry.Show stereochemistry in a meso compound.In cases where there is more than one answer, just draw one. (use same instructions below)
1b) Draw the structure of a compound that is a stereoisomer of cis-1,2-dimethylcyclopentane.1c) Draw the structure of a compound that is a stereoisomer of cis-1,2-dimethylcyclobutane.
Answer:
Explanation:
A stereoisomer refers to an isomer that shares an identical bonding structure but differs in the geometric position of functional groups and atoms.
Stereoisomers are molecules which have the same semi-expanded formula, but a different arrangement in space.
They are isomers with a similar structural formula, yet which contrast just in their spatial geometry.
From the given question, we are provided with some set of instructions to draw the structure of the following compounds.
stereoisomer of trans-1,2-dibromocyclobutane
cis-1,2-dimethylcyclopentane
cis-1,2-dimethylcyclobutane

Is this a model of an element, a compound, or a mixture? Explain your reasoning.
Answer:
A mixture.
Explanation:
The image contains two types of molecules: one with a blue centre and one with a green centre. They are both compounds, as they contain atoms of different elements that are chemically combined/ bonded to each other. As the molecules of the different compounds are not bonded to each other, the model must show a mixture.
A mixture: a combination of molecules of different elements and/or compounds that are not chemically combined e.g. salt dissolved in water.
An element: a substance containing only one kind of atom e.g. oxygen.
A compound: a substance containing two or more kinds of atoms (atoms of different elements) are chemically bonded to each other e.g. water.
In the model of an element, it represents a mixture. The correct option is b.
What is a mixture?A mixture is a non-chemically coupled combination of molecules from different elements and/or compounds, such as salt dissolved in water.
There are two kinds of molecules in the image: one with a blue center and one with a green center. They are both compounds because they contain atoms of different elements that have been chemically combined/bonded. Because the molecules of the various compounds are not bound to one another, the model must depict a mixture.
A compound is a substance that contains two or more types of atoms (atoms of different elements) that are chemically bound to one another, such as water.
Therefore, the model shows a mixture.

Most of the dissolved substance in sea water is: hydrogen chloride nitrogen sodium ANSWER NOW! I NEED HELP ASAP! WILL GIVE BRAINLIEST!
Answer: Sodium chloride
Explanation:
Ocean water contains a number of substances. When a substance which has ionic bonds is dissolved in water it takes the form of ions.
The most common ions in ocean water are sodium and chloride. These are the ions formed when common salt, sodium chloride (NaCl) is dissolved in water.
Sodium chloride accounts for about 3% of ocean water by mass.
Answer:
By far, the most abundant elements are hydrogen and water.
Explanation:
The analysis of the 77 sea water samples taken during the Challenger's 3-year voyage did much to lay the foundations for determining the chemical content of sea water. By far, the most abundant elements are hydrogen and water (combined to make water). Together, these elements make up 96% of sea water. Sodium chloride and magnesium make up just under 4% of sea water. Trace amounts of 97 other elements are found in the remaining 0.08%. Of the trace elements, calcium, potassium, sulfur, and bromine are the most abundant.

A pitcher throws a 142 g baseball, which accelerates at a speed of 9 m/s^2. How much force does the pitcher apply to the ball?
Answer:
The answer is 1.28 NExplanation:
The force acting on an object given the mass and acceleration we use the formula
force = mass × accelerationFrom the question
mass = 142 g = 0.142 kg
acceleration = 9 m/s²
We have
force = 0.142 × 9 = 1.278
We have the final answer as
1.28 NHope this helps you
Answer:
1.28
Explanation:
In order for you to get the force you have to multiply the mass & acceleration. The baseball mass is 142 g and the acceleration is 9. So you will calculate 0.142 x 9 and that will give you 1.278. You will then round the 7 to an 8 and then you get the answer 1.28.

What causes the emission of light?
Answer:
When the electrons in the atom are excited, for example by being heated, the additional energy pushes the electrons to higher energy orbitals. When the electrons fall back down and leave the excited state, energy is re-emitted in the form of a photon. The wavelength (or equivalently, frequency) of the photon is determined by the difference in energy between the two states. These emitted photons form the element's spectrum.
The fact that only certain colors appear in an element's atomic emission spectrum means that only certain frequencies of light are emitted. Each of these frequencies are related to energy by the formula:
{\displaystyle E_{\text{photon}}=h\nu }E_{\text{photon}}=h\nu ,
where {\displaystyle E_{\text{photon}}}E_{\text{photon}} is the energy of the photon, {\displaystyle \nu }\nu is its frequency, and {\displaystyle h}h is Planck's constant. This concludes that only photons with specific energies are emitted by the atom. The principle of the atomic emission spectrum explains the varied colors in neon signs, as well as chemical flame test results (described below).
The frequencies of light that an atom can emit are dependent on states the electrons can be in. When excited, an electron moves to a higher energy level or orbital. When the electron falls back to its ground level the light is emitted.
