Is a change in matter that produces one or more substances
Chemical change
Physical change
Chemical reaction
Answer:
Chemical change
Explanation:
A chemical change happens when one chemical substance is transformed into one or more different substances, such as when iron becomes rust. Chemical changes occur through the process of chemical reactions, and the resulting substances have different properties because their atoms and molecules are arranged differently.
its not physical change: What is a physical change? A physical change is a change to the physical—as opposed to chemical—properties of a substance. They are usually reversible. The physical properties of a substance include such characteristics as shape (volume and size), color, texture, flexibility, density, and mass.
its not chemical reaction: A chemical reaction is a process in which one or more substances, also called reactants, are converted to one or more different substances, known as products. A chemical reaction rearranges the constituent atoms of the reactants to create different substances as products

Why does Mercury have almost no atmosphere?
Mercury spins on its axis too fast to have an atmosphere.
Radiation from the Sun blows the atmospheric particles off into space.
Mercury's gravity is too weak to hold an atmosphere.
Mercury orbits the Sun at such high speed that the atmosphere is blown away.
Answer:
There are two main reasons. First, Mercury is small and doesn't have much gravity so it's hard to hold onto an atmosphere. Second, Mercury is close to the Sun so any atmosphere gets blasted away by stuff being blown off the Sun.
Explanation:
Because Mercury has no atmosphere, it can't hold onto its heat very well. The night side of Mercury gets very cold, which brings down the average temperature of the planet and makes it only the second hottest planet in the Solar System after Venus.

1. Artificial diamonds are made using thallium carbonate. If thallium has an oxidation number of 1+, what is the formula for the compound?
2. Explain what electric forces between oppositely charged electrons and protons have to do with chemical reactions.
3. If the linear molecule beryllium dichloride (BeCl₂) has polar bonds because CI attracts electrons more strongly than Be, why is the molecule nonpolar?
Answer:
Artificial diamonds are made using thallium carbonate. If thallium has an oxidation number of 1+ number 2 A chemical bond is a lasting attraction between atoms, ions or molecules that enables the formation of chemical compounds. The bond may result from the electrostatic force of attraction between oppositely charged ions as in ionic bonds or through the sharing of electrons as in covalent bonds. number 3 giant metallic, giant ionic, simple molecular, and macromolecular ... it has positive ions surrounded by a sea of delocalised electrons ... m/z value than Cl⁻. this means that F⁻ is more attracted to the Ca²⁺ ion more strongly ... What bond angle does beryllium chloride, BeCl₂ have? ... Give two examples of linear molecules.
The formula of thallium carbonate is Tl₂CO₃. The intermolecular force of attraction between electrons and protons proceed to the combination of two atoms. The net dipole moment in BeCl₂ is zero since they cancel each other due to linear geometry.
What is thallium carbonate?Thallium carbonate is an inorganic compound formed by the ionic bonding between thallium and carbonate group. The charge of thallium Tl is +1 and that of carbonate group is -2. Hence the chemical formula of the compound is Tl₂CO₃.
Unstable atoms with deficient number of electrons combines with other atoms to form compounds. The force that act between the two atoms is called intermolecular force of attraction.
The electrons of an atom is attracted by the positive charge of nucleus of other atom results in the chemical bonding.
Barium chloride is an ionic compound with linear geometry. The chlorine atom is highly electronegative and will attract the shared pair of electrons into it.
The two chlorines are arranges linearly on either side of Be thus, the dipole will be opposite in direction towards each chlorine atoms. Thus it cancel and net dipole moment become zero. That's why the compound is nonpolar.

Which statement best compares segmented worms and roundworms?
Some segmented worms have setae, but roundworms do not.
Some roundworms have setae, but segmented worms do not.
Segmented worms have sense organs, but roundworms do not.
Roundworms have sense organs, but segmented worms do not.
The statement which best compares segmented worms and roundworms is that some segmented worms have setae, but roundworms do not.
What are roundworms?Roundworms constitute the phylum Nematoda (also called Nemathelminthes), with plant-parasitic nematodes also known as eelworms. They are a diverse animal phylum inhabiting a broad range of environments. Less formally, they are categorized as helminths, but are taxonomically classified along with arthropods, tardigrades and other moulting animals in the clade Ecdysozoa, and unlike flatworms, have tubular digestive systems with openings at both ends. Like tardigrades, they have a reduced number of Hox genes, but their sister phylum Nematomorpha has kept the ancestral protostome Hox genotype, which shows that the reduction has occurred within the nematode phylum.
Nematodes species can be difficult to distinguish from one another. Consequently, estimates of the number of nematode species described to date vary by author and may change rapidly over time. A 2013 survey of animal biodiversity published in the mega journal Zootaxa puts this figure at over 25,000. Estimates of the total number of extant species are subject to even greater variation.

. Guillermo was finding it difficult to walk up the steps to his family’s apartment. His doctor thinks that his cells might not be getting enough oxygen or glucose. Which body systems should the doctor test in order to find out whether Guillermo’s cells are getting enough oxygen and glucose and why? (Sentence starter: The body systems Guillermo should have tested are .
Answer:
Because oxygen is the combustion fuel and glucose is the substrate needed for synthesis of energy as ATPs during cellular respiration.Therefore Guillermo lacks enough energy as ATPs in her body cells, especially skeletal muscles cells to complete the task of ascending the s steps.
For all the mitochondrial in cells(sites of energy production) to receive needed glucose,and other metabolites needed for energy synthesis; an efficient transport system is needed, so that these materials are available immediately, in required amount. This system is called circulatory system.
And for the the supply of combustion fuel (oxygen) needed for the completion of the ATP synthesis mechanisms; respiratory systems which convey oxygen from the external environments to the circulatory system through breathing mechanisms, for distribution is needed.
Thus the doctor needs to test both the circulatory and respiratory systems.
