Things That Are Not Matter Here are several things that don't meet the definition of matter: Time Sound Sunlight Rainbow Love Thoughts Gravity Microwaves Heat Memories Information Reflections Energy table sugar, or sucrose (C12H22O11) II. All of the following can be considered physical properties EXCEPT: A block of aluminum is (a) ground into aluminum powder and then (b) ignited. D) It doesn't interact with any type of baryonic matter. A. 1. BECs are a strange, lab-made form of matter in which thousands of separate atoms seem to act as one "super atom.". Chemical Which of the following is NOT considered a form of matter? If there were nothing between a cloud and the ground, it would fall. b) Na and Cl. The diagnosis usually signals a less favorable neurodevelopmental . Both of the illustrated reactions are exergonic and release the same amount of energy during product formation. Which of the two compounds in the pair below is more basic in water? In the biosphere, the total amount of matter remains constant over time, whereas the total amount of energy decreases over time. The negatively charged chloride anion has dissociated from the salt crystal and formed an interaction with the slightly positively charged hydrogen atoms of several water molecules. 14) Which of the following best sums up current scientific thinking about the nature of dark matter? Which of the following are meso compounds? one potassium atom and one fluorine atom C) Dark matter is present in individual galaxies, but there is no evidence that it can exist between the galaxies in a cluster. Which of the resulting solutions would NOT conduct electricity? The hydrocarbon groups that dominate the structure of triglycerides are the basis for the efficient and compact energy storage by fat. 17) What is the primary form of evidence that has led astronomers to conclude that the expansion of the universe is accelerating? Which of the following is NOT considered a form of matter? 17) Imagine that it turns out that dark matter (not dark energy) is made up of an unstable form of matter that decays into photons or other forms of energy about 50 billion years from now. False, Except for elements with atomic number 1 and 2, all other elements are stable with how many electrons in their outermost (valence) energy level? A) Hubble's law of expansion applies only to the space between galaxies. 3. protein Which of the following compounds are ionic and which are covalent: N2, CCl4, SiO2, AlCl3, CaCl2, LiBr. A. Write the formula for the oxide corresponding to the highest expected oxidation state for. isomerase Hydrogen, Ionic, Covalent. 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. Atomic weight is determined by the number of protons in an atom of a given element. 3. energy storage an R group There's even a strange type of matter, known as a chain-melted state, that stably exists as both a solid and liquid at once. Which of the following are elements and which are compounds? D) Neutrinos travel at extremely high speeds and can escape a galaxy's gravitational pull. Periventricular leukoencephalopathy (PVL) is a pathologic process that has attracted little attention in neurodiagnosis. Which of these terms would best classify the enzyme represented in the figure? C) The expansion rate has been increasing with time (an accelerating universe). a) carbon b) antimony c) chlorine d) calcium, Which compound or compounds is (are) most likely to form dication(s)? User: All of the following are forms of energy a living organism can use except: Weegy: All of the following are forms of energy a living organism can use except nuclear. 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. The polarity of water allows it to easily dissociate most covalently bound compounds. A glass holds H20 in three states of matter: ice (solid), water (liquid) and vapor (gas). B) We have moderately strong evidence that the acceleration is real, but essentially no idea what is causing it. Classify (a) and (b) as chemical or physical changes. B) Dark energy does not exist and there is much more dark matter than we are aware of to date. Chemical Fiverr. Polar covalent bonds involve the transfer of electrons from electropositive atoms to electronegative atoms. What element is representative, nonmetallic, belongs to group VA, and forms a covalent compound with oxygen? 32, Sodium has one valence electron, while chlorine has seven. a solution D) We detect this gas with X-ray telescopes. Describe the compounds that form between nonmetals. 3) The text states that luminous matter in the Milky Way seems to be much like the tip of an iceberg. Energy cannot be converted from one form to another, it can only be created or destroyed What explains the partial negative charge on the oxygen atom within the water molecule? c) Al and C. d) N and O. True For this to be the case, which of the following would have to be true (based on current understanding)? D) faint red stars The correct ratio is two hydrogens and one oxygen for every carbon. a phosphate group. Because they don't reach equilibrium or a steady state, they are able to dodge the second law of thermodynamics, which states that the disorder, or entropy, of a closed system, always increases. True 8) How does gravitational lensing tell us about the mass of a galaxy cluster? protein Hydrogen bonding between certain amine and carboxyl groups creates alpha helices and beta-pleated sheets. for example, the radius of the sun is approximately 696,000 kilometers, while bacterial cells are as small as 1.9 10-4 millimeters. H2 + O2 H2O exchange; equilibrium. water It does not have mass and volume. Fermions normally like to be alone, but to create this matter phase, scientists have to coax them to pair up. Which of the following is not a fundamental subatomic particle that forms elements? a sodium ion C) The actual density of dark matter and luminous matter combined is no more than about 1% of the critical density. The substrate absorbs chemical energy from the enzyme after binding to its active site. This problem has been solved! B) They are subatomic particles. III<1
