Some questions frequently asked by users : six types of chemical reaction worksheet?
balance the following reaction and indicate which of the sice types of chemical reaction are being represented: 3) ___c^5h^9o _____o^2 -->____co^2 +_____h2o type of reaction :________ im not really smart in the chemistry area so can you explain how do i get a balance reaction and tell me what type of reaction it is ..im really don't care if you can't answer the "type of reaction" just show me how i can solve this reaction so i can do the other myself. thanksanswers for identifying chemical reactions worksheet?
starts off by saying text book identifies 4 diff types of chemical reactions. has 23 questions along with a-g q'swhere can i find prentice hall chemistry worksheet answers?
i need chapter 11 section 2: types of chemical reactions plz plz plzchemistry worksheet help!:/ 10 points to the best answer!?
9) a chemical equation is balanced when the a. coefficients of the reactants equal the coefficients of the products. b. same number of each kind of atom appears in the reactants and in the products. c. products and reactants are the same chemicals. d. subscripts of the reactants equal the subscripts of the products. 12) which coefficients correctly balance the formula equation nh4no2→n2+h2o? a. 1,2,2 b. 1,1,2 c. 2,1,1 d. 2,2,2 13) a reaction of hydrocarbon such as c3h8, in which carbon dioxide and water are produced, is classified as a a. decomposition reaction. b. combustion reaction. c. double-displacement reaction. d. synthesis reaction. 14) in what kind of reaction do two or more substances combine to form a new compound? a. decomposition reaction. b. ionic reaction. c. double-displacement reaction. d. synthesis reaction 16) the equation a+bx→ax+b is the general equation for a a. double-displacement reaction. b. decomposition reaction. c. displacement reaction. d. combustion reaction. 18) the coefficients in a chemical equation represent the a. masses, in grams, of all reactants and products. b. relative numbers of moles of reactants and products. c. number of atoms in each compound in a reaction. d. number of valence electrons involved in the reaction. 19) in the reaction 2h2+o2→2h20, what is the mole ratio of oxygen to water? a. 1:2 c.8:1 b.2:1 d.1:4 20) a chemical reaction involving substances a and b stops when b is completely used. b is the a. excess reactant c. primary reactant b. limiting reactant d. primary product 21) tell what type of chemical reaction is represented by the following chemical equation. then balance the equation. c2h8+o2→co2+h20 22) how many grams of ammonium sulfate can be produced if 30.0 mol of h2so4 react with the excess nh3 according to the equation _____nh3+_____h2so4→______(nh4)2so4? p.s. the lines mean that this equation isnt balanced. 23) how many moles of silver can be produced if 12 moles of cu are reacted with the excess agno3 according to the equation _____cu+____agno3→______ag+______cu(no3)2? p.s. the lines mean that this equation isnt balanced. 24) how many grams of water are produced when 250 grams of nh3 are reacted? _____nh3+_____co2→nh2conh2+_____h20 p.s. the lines mean that this equation isnt balanced. 25) how many grams of lithium carbonate will be produced if 1250 grams of lithium hydorxide reacts with unlimited carbon dioxide? _____lioh+______co2→______li2co3+_____h20 p.s. the lines mean that the equation is unbalanced. thanks guys fer the helppp!(:science worksheet 10 points for all the answers?
1. _________________ are living things that can make their own food. 2. _________________ is a process of making food from sunlight, carbon dioxide and water. 3. _________________ are living things that must ingest or absorb their food. they can not make food internally. 4. _________________are the type of cells that do not contain a nucleus or membrane bound organelles like mitochondria. they only exist in single celled organisms. only bacteria contain this type of cell. 5. _______________ are the type of cells that contain a nucleus and membrane bound organelles like mitochondria. protist, fungus, plant and animals all have this type of cell. 6. plant cells have a _________________ for protection and _______________for photosynthesis. animal cells do not contain these things. 7. _______________ are organelles (or cell parts) used for helping make proteins. 8. _______________ are organelles that make energy for the cell. 9. the _______________is the area of the cell that contains the dna. 10. the _____________________ is a series of folded membranes used for transportation in the cell. there are two types. the smooth type helps to make lipids (fats) for the cell and the rough type contains ribosomes for making proteins. 11. ___________________ is the semi-liquid substance that separates all the organelles inside the cell. it is also the area where a lot of chemical reactions in the cell take place. 12. __________________ are storage organelles. the plant cell has one large one that can take up about 2/3 or the volume of the cell. 13. a ______________is a semi-rigid structure made out of sugar. it is located outside the cell membrane. it helps protect the cell. 14. the __________________ is also called a plasma membrane. all cells contain this part. it controls what substances come into and out of the cell. 15. __________________ are organelles that store chlorophyll and other pigments used in photosynthesis. 16. __________________ are organelles that modify, store and transport proteins as the cell needs them. 17. ___________________are digestive organelles. they contain enzymes that break down waste in the cell. white blood cells in animals have a lot of these organelles. 18. ________________ are proteins that are used in chemical processes throughout the cell. these special proteins run the metabolism of living things. without them, the chemical processes in living things would be ciaos. 19. _________________is the movement of a substance from an area where there is more of the substance to an area where there is less of the substance. it does not require any energy. osmosis is a type. osmosis is a term used when the substance being transported is water. 20. ___________________ is the cellular movement of a substance that requires the use of energy. 21. ___________________is the cellular movement of a substance that does not require energy. 22. _____________________ is the way cells make energy. there are two types aerobic (requires oxygen) and anaerobic (no oxygen present). aerobic makes the most energy! 23. _____________________is the process of dividing regular body cells. if a starfish looses a ray (limb) then this will regenerate it. 24. ____________________is the process of cell division that produces sperm, eggs or spores. the amount of dna in the new cells is half the amount in the parent cell. 25. the cell cycle is the life cycle of a cell. 90% of the cell cycle is spent in _________________. the other 10% of the cell cycle is spent in mitosis.
