8th Grade Science Law of Conservation of Matter Review Terms in this set (15)Law of Conservation of Matter States that, during a chemical reaction, matter cannot be created or destroyed. Even though the matter may change from one form to another, the same number of atoms exists before and after the changes take place. reactant The substances there before the chemical reaction occurs. product The substances there after the chemical reaction takes place. molecule Smallest unit of a compound; two atoms joined chemically. subscript Small number written to the right and slightly below a chemical symbol; indicates the number of atoms of that particular element in that compound. coefficient Number written before a chemical formula; shows how many molecules of a compound are present. What cannot happen in the Law of Conservation of Matter? Matter cannot be destroyed or created What can happen in the Law of Conservation of Matter? Matter can change state or form equals The mass of the products always ___________ the mass of the reactants. chemical equation Uses chemical symbols and chemical formulas to describe a chemical reaction. What is the relationship between the reactants' and the product's masses? The mass of the reactants equals the mass of the product; 305 grams If a student mixed 100 grams of sugar, 200 grams of water, and 5 grams of flavoring, how much will the solution weigh? closed system The environment where matter cannot enter or escape matter Anything that has mass balance Scientific tool essential for testing the Law of Conservation of Matter Students also viewedMis Primeros Versos18 terms Jeff_Gerencser8 Geometry: Lines, Angles, and Proofs Voca…13 terms Brittany_Ramsey6thTeacher Chemical Reactions and The Law of Conser…12 terms fly_free__ Post-WWII and Civil Rights Movement13 terms Elizabeth_Hicks67 Sets found in the same folderBehavior of Light Waves5 terms GregoireEC Electricity and Magnetism24 terms GregoireEC Measurement and Calculations Chemistry50 terms eswaneylw210 Chemistry Practical33 terms Tiffany_Wong88 Other sets by this creator5th Grade ELA Vocabulary Week 183 terms GregoireEC 5th Grade ELA Vocabulary Week 168 terms GregoireEC 5th Grade ELA Spelling Week 1520 terms GregoireEC 5th Grade ELA Vocabulary Week 157 terms GregoireEC Verified questions
engineering The function $y ( t ) = 1 - e ^ { - b t } ,$ where $t$ is time and $b > 0 ,$ describes many processes, such as the height of liquid in a tank as it is being filled and the temperature of an object being heated. Investigate the effect of the parameter $b$ on $y ( t ) .$ To do this, plot $y$ versus $t$ for several values of $b$ on the same plot. How long will it take for $y ( t )$ to reach 98 percent of its steady-state value? Verified answer
engineering The main waterline into a tall building has a pressure of 90 psia at 16 ft elevation below ground level. How much extra pressure does a pump need to add to ensure a waterline pressure of 30 psia at the top floor 450 ft above ground? Verified answer
engineering Drag measurements were taken for a sphere with a diameter of 5 cm, moving at 4 m/s in water at $20^{\circ} \mathrm{C}$. The resulting drag on the sphere was 10 N. For a balloon with 1-m diameter rising in air with standard temperature and pressure, determine (a) the velocity if Reynolds number similarity is enforced and (b) the drag force if the drag coefficient is the dependent pi term. Verified answer engineering Show that for a signal of eight sample values, $$ w=e^{-i/4}=(1-i)/√2. $$ Check by squatting. Verified answer Recommended textbook solutions

The same amount of matter exists before and after the change—none is created or destroyed. This concept is called the Law of Conservation of Mass.
What is the law of conservation of matter quizlet?Law of Conservation of Matter. States that, during a chemical reaction, matter cannot be created or destroyed. Even though the matter may change from one form to another, the same number of atoms exists before and after the changes take place.
What is the law of conservation of mass and energy quizlet?In any physical change or chemical reaction, mass is conserved; mass can be neither created nor destroyed. Law of Conservation of Energy. a law of science that states that energy cannot be created or destroyed, but only changed from one form into another or transferred from one object to anothe.
Which statement best describes the law of conservation of mass quizlet?Which best describes the law of conservation of mass? The mass of the reactants and products is equal and is not dependent on the physical state of the substances.
