Which statement correctly describes a chemical reaction?O Reactants come out of a reaction.O Energy is always released.O Bonds between atoms break and new bonds form.O Products go into a reaction. Products go into a reaction, Mark this and return Save and Exit Sube A. Which statement describes a chemical reaction at equilibrium? B. A. (1) The concentrations of the products and reactants are equal. The products have higher potential energy than the reactants, and the ÎH is negative. a) Reactant molecules and product molecules have the same velocity. Which statement describes a chemical reaction at equilibrium? Identify the statement which does not describe the property of alkenes. The rearrangement of atoms constitutes a chemical reaction, although some phase changes can also qualify. Which statement best describes how a catalyst can speed up a chemical reaction? B. The reactants are what are "reacting". A catalyst strengthens the bonds of the reactants increasing the activation energy. Which statement correctly describes a chemical reaction? C. The forward reaction happens at the same rate as the reverse reaction. C. The products have lower potential energy than the reactants, and the ÎH is negative. 10. The products are what is formed. A. The products don't react. They absorb oxygen from the enviornment. 1. they control the transport of materials. The catalyst increases the concentration of products. Which statement best describes evidence that a chemical reaction occurs as a cake bakes?A The water in the cake evaporates.B The cake rises as gas bubbles form in the baking cake.C The cake takes the shape of the container in which it is baked.D The water in the cake batter is used to keep the They are unsaturated hydrocarbons. The products have higher potential energy than the reactants, and the ÎH is positive. 3.they affect the rate of chemical reactions. The catalyst increases the concentration of reactants. the rearrangement of atoms by breaking and reforming chemical bonds a reaction that absorbs heat from the surroundings a reaction that releases heat to the surroundings the rearrangement of molecules based on temperature and pressure Which best describes a chemical reaction? B. The reaction has stopped because all reactants have been used up. (2) The concentrations of the products and reactants are constant. O Reactants come out of a reaction. 4. or D. The products have lower potential energy ⦠2. they provide energy for chemical reactions. Clearly two of these can be eliminated. The forward reaction happens slightly faster than the reverse reaction. (3) The rate of the forward reaction is less than the rate of the reverse reaction. Some reactions appear to be âsubstitutionâ of an alkene, but in fact, is the result of an âaddition-eliminationâ sequence of reactions. Which statement describes all enzymes? The catalyst makes lower energy pathways available. (1 point) A catalyst weakens the bonds of the reactants lowering the activation energy. Please put the number of the answer i ⦠D. The reaction has stopped until a stress is applied to the system. The catalyst binds to enzymes to release substrates. Which statement correctly describes what transpires during a chemical reaction? Which statement correctly describes an endothermic chemical reaction? Energy is always released Bonds between atoms break and new bonds form. Aug 2002-13 Which statement correctly describes a chemical reaction at equilibrium? They decolourises bromine water. Chemical reactions are an integral part of technology, of culture, and indeed of life itself.Burning fuels, smelting iron, making glass and pottery, brewing beer, and making wine and cheese are among many examples of activities incorporating chemical reactions that have been known and used for thousands of years.
