which of the following is not a form of matter
oxygen gas b.) What kind of elements will form an ionic compound? Several pieces of graphite from a mechanical pencil are (a) broken into tiny pieces. The four natural states of matter are: Solids, liquids, gases and plasma. 2 A) The temperature is always directly related to mass, which is why massive objects are always hotter than less massive objects. The left reaction is exergonic, and the right reaction is endergonic. Both atoms and molecules are held together by a form of potential energy called chemical energy (opens in new tab), according to the U.S. Energy Information Administration. substrates Physical alkaline solution Why? hydrogen. H2 + O2 H2O True Which of the following statements regarding matter is FALSE? Small atoms with 6 or 7 valence shell electrons tend to be electronegative. Basically, any type of energy or any abstract concept is an example of something that is not matter. B) studying X-ray emission from hot gas inside the cluster an R group Which of the two compounds in the given pair is more basic in water? Time crystals were created in a lab in 2017 and in 2021, Google announced that it had made a time crystal in a quantum computer, and that the crystal had lasted for 100 seconds before the ephemeral state disintegrated. Which of the following is NOT an example of a physical property? Hence, it is matters. C) The universe is not old enough yet for these objects to begin their expansion. A) We infer its existence by observing its gravitational effects on the galaxy motions. phosphorus and nitrogen 18) Gravitational lensing occurs when 19) Which of the following is not evidence for dark matter? What is the name of the binary nonmetal compound CS2? A) the flat rotation curves of spiral galaxies Solids include things like solid ice, sugar, rock, wood, etc. What is the common ending for the nonmetal portion of the name? B) Dark matter is present between galaxies in clusters, but not within individual galaxies. buffer. Matter is a general term describing any 'physical substance'. 3. hydrolase 10) When we say that a cluster of galaxies is acting as a gravitational lens, what do we mean? False. Most famously, black holes were predicted by Einstein's theory of general relativity, which showed that when a massive star dies, it leaves behind a small, dense remnant core. two double bonds Which of the following elements does not exist as a diatomic molecule? a. I2 b. Cl2 c. Br2 d. F2. B) rotation curves of disk galaxies A) Dark matter is the dominant form of mass in both clusters and in individual galaxies. f(x)=3x4+5x2f(x)=-3 x^{4}+5 x^{2}f(x)=3x4+5x2. Which of the following compounds contains an ionic bond? C and Fe b. Na and Cl c. Al and C d. H and O. Which of the following compounds contains the Mn3+ ion? Would water still be a polar molecule if it were NOT in the form of a V but rather were linear like carbon dioxide? (a) Pb and N (b) Au and Cu (c) F and P (d) Ge and O (c) H and B, Which of the following pairs of elements would be most likely to form an ionic compound? protein a. H2O b. HCl c. N2 d. NH3 e. CaCl2, Which of the following is an ionic compound? D) telescope lenses are distorted by gravity. I < III < II Matter exists in three states: solid, liquid and gas. In a liquid, the particles are more loosely packed than in a solid and are able to flow around each other, giving the liquid an indefinite shape. What type of chemical bond is most likely to occur between sodium and chlorine? the breaking of chemical bonds within the reactants. I. Ionic Time crystals are made in the lab and have the ability to cycle between two states of energy without ever losing energy. Non-matter includes the light from a torch, the heat from a fire, and the sound of a police siren. 2. D) The expansion rate is slowing dramatically with time (a recollapsing universe). oxidase The cargo space of a refrigerated truck whose inner dimensions are 12m2.3m3.5m12 \mathrm{~m} \times 2.3 \mathrm{~m} \times 3.5 \mathrm{~m}12m2.3m3.5m is to be precooled from 25C25^{\circ} \mathrm{C}25C to an average temperature of 5C5^{\circ} \mathrm{C}5C. four A) measuring the speeds of galaxies orbiting the cluster's center A BEC was first created by scientists in 1995. Why? molecule Specialties: Mission of Modern: To promote the highest quality of health for patients with skin disease through the provision of empathetic, state-of-the-art medical care. Much like solids, liquids (most of which have a lower density than solids) are incredibly difficult to compress. Matter can exist in one of three main states: solid, liquid, or gas. The solid matter has a defined shape, boundaries, and fixed volumes, implying that it is not compressible. Rank the chemical bonds from relatively weakest to strongest. It does not have mass and volume. D) Clusters and superclusters appear to be randomly scattered about the universe, like dots sprinkled randomly on a wall. The chemical composition of carbohydrates includes two oxygens and one hydrogen for every carbon present. nonpolar covalent The enzyme-substrate complex undergoes internal rearrangements that form the product(s). Objects that have mass and are matter may emit energy. (Comparison of activation energy with and without an enzyme.) B) The actual density, even with dark matter included, is less than about a third of the critical density. 3) The text states that luminous matter in the Milky Way seems to be much like the tip of an iceberg. Thus it is showing inertia. Answer 2: Light and sound are not regarded as forms of matter. Weak acids and bases dissociate (ionize) partially and reversibly, whereas strong acids and bases dissociate completely and irreversibly. D) observations of white dwarf supernovae. Unlike BECs, they are made up of fermions, a type of matter that includes protons, neutrons and electrons with odd atomic numbers. A) the higher amount of mass relative to light (higher mass-to-light ratio), the lower the proportion of dark matter. It then emits flames and smoke. 1. 1) Which of the following best summarizes what we mean by dark matter? III<1
