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.

Answer:

mountain ranges form when pieces of Earth's crust—called plates—smash against each other in a process called plate tectonics, and buckle up like the hood of a car in a head-on collision.

Hope that answers your question.

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.

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.

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.

Amino Acids

Explanation:

Answer : The image C shows homogeneous mixture and image A, B and D shows heterogeneous mixture.

Explanation :

Heterogeneous mixtures : It is a mixture in which the constituent substances are not mixed well and do not have a uniform composition throughout the mixture that means appears non-uniformly throughout the solution.

Homogeneous mixtures : It is a mixture in which the constituent substances are mixed well and have a uniform composition throughout the mixture that means appears uniformly throughout the solution.

From the given image we conclude that the,

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

Some examples of colorful light emissions are street lights, neon signs and, of course, fireworks. Neon signs emit light when an electric current passes through the neon gas.

Answer:

(1) the same chemical properties .

Explanation:

Hello!

In this case, among the options:

(1) the same chemical properties

(2) the same volume

(3) different temperatures

(4) different empirical formulas

We can see that they have the same chemical properties as they at the same conditions, same type of bond (polar), molecular geometry, bond angle (104.5 °) and so on. Nevertheless, at STP (1 atm and 273.15 K) they do not have the same volume since the larger the mass, the larger the volume, they have the same temperature and the both of them are H₂O.

It means that the answer is (1) the same chemical properties .

Answer:

80.07 g/mol

Explanation:

Step 1: Define

Molar Mass S - 32.07 g/mol

Molar Mass O - 16.00 g/mol

Step 2: Find molar mass of compound

S = S × 1 = 32.07 g/mol

O₃ = O × 3 = 48.00 g/mol

32.07 + 48.00 = 80.07 g/mol

Explanation:

The force acting on an object given the mass and acceleration we use the formula

From 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

Hope 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.

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.

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.
