What Is The Reactivity Of Group 1? The reactivity of Group 1 elements increases as you go down the group because: … the outer electron gets further from the nucleus as you go down the group. the attraction between the nucleus and outer electron gets weaker as you go down the group – so the
What Is The Mass Of A Graham Cracker? Food Element Molar Mass C, Chocolate Rectangle 3.30 g/mol G, Graham Cracker Square7.00 g/mol M, Marshmallow 7.10 g/mol What is the unit mass of a graham cracker? Substance Symbol Unit mass Graham Cracker Squares Gr8.50 g Marshmallow Mm 7.125 g Miniature Chocolate Bar Ch 12.00 g How
Are Moles Conserved In A Chemical Reaction? Moles are not strictly conserved when compounds are involved, but moles of atoms are always conserved in chemical reactions. Why are moles not conserved during a chemical reaction? Mass is not conserved in chemical reactions. … Mass is therefore never conserved because a little of it turns into
Are Reactants On The Right Or Left? Reactants are on the left and products are on the right. … If the reactants and products are equal in energy, at equilibrium, they will have the same concentration. If the products are lower in energy, there will be a higher % of the products in the equilibrium
Does Reaction Order Increase With Temperature? Effect of Temperature on Reaction Rates. The orders of reaction are independent of temperature – orders change only when the reaction changes. Thus, the entire temperature dependence of a reaction, as expressed in a rate law, is found in the rate constant, k. What is the effect of temperature
How Do The Products Of Chemical Reactions Compare To Their Reactants? A reactant is a substance that is present at the start of a chemical reaction. The substance(s) to the right of the arrow are called products . A product is a substance that is present at the end of a chemical reaction. Does the
Which Reaction Is Faster SN1 Or SN2? Explanation: SN1 will be faster if: 1. Reagent is weak base. Why is SN2 faster? The reason that the alkyl halide is preferred to be primary is because the mechanism for these reactions is SN2. SN2 indicates a substitution reaction that takes place in one step. … This
Why Do Double Displacement Reactions Occur? Double displacement reactions occur when a part of two ionic compounds are exchanged and make two new components. … These reactions are ionic in nature. The reactants get transformed into ions when dissolved in water and exchange of ions occur in the solution and results in the formation of
How Do You Know If A Reaction Is Zero First Or Second Order? A zero-order reaction proceeds at a constant rate. A first-order reaction rate depends on the concentration of one of the reactants. A second-order reaction rate is proportional to the square of the concentration of a reactant or the product of the concentration
How Do You Find The Half Life Of A Zero Order Reaction? For a zero-order reaction, the mathematical expression that can be employed to determine the half-life is: t1 / 2 = [R]0/2k. For a first-order reaction, the half-life is given by: t1 / 2 = 0.693/k. For a second-order reaction, the formula for the
