When giving the rate of a chemical reaction why would it be significant to know that the reaction rate is an average reaction rate?
Nataliemariedionne
Reaction rates are dependent on the concentration of reactants. As a reaction proceeds, the reactants are used up and thus their concentration is lowered. THis means that the maximum rate of reaction will be at or immediately after time zero, when the reaction is only just begun, and the minimum will be when one or more of the reactants' concentrations have reached zero.
Thus, any rate stated for the reaction would only hold for a specific time in the reaction progress and cannot be extrapolated to cover all of that progress. So a mean rate of reaction must be used; this can tell a person, when combined with either the time of beginning, time of ending, or the initial concentrations, what any of the others were for the reaction in question. This is impossible to do if given a specific rate and the time it applied to; you cannot calculate any new information from just those two data.

How you can tell if a mixture is a chemical reaction?
a mixture is by definition not a chemical reactionA mixture is two or more substances which have been combined such that each substance retains its own chemical identity.So a mixture cannot be a chemical reaction, signs of a chemical reaction include:colour changeprecipitation (formation of a solid)effervescence (giving off gas)And every single chemical reaction involves gives of some heat.
What pieces of information is giving in a half-reaction?
To the left of a chemical equation are the reactants and to the right are the products.
Why does fire get so hot?
See, every chemical reaction results in... 1) giving of odour 2) giving of heat & 3) a completely new product. Fire is nothing but a chemical reaction between Oxygen and photons/electro radiation.
What chemical changes involve breaking and making chemical bonds?
Breaking of bonds but also formation of new bonds.
Fireworks exploding in the sky and giving off light are an example of an what?
A chemical reaction (combustion of gunpowder); Newton's laws of motion; the varying spectrums of transition metal compounds.
What is an endothothermic reaction?
A chemical reaction whereby it takes in heat as supposed to giving it out (as opposed to an exothermic reaction).
What is the formula to completely dissolve baking soda into vinegar?
impossible as it will bubble of a chemical reaction giving off an endothermic reaction

In a firework show the fireworks explode giving off heat and light is this a chemical change why?
It is a chemical change because the chemical composition is changed during this reaction.
Does fire have more than one element in it?
Yes. A fire is a chemical reaction giving off heat. The reaction requires material with more than one element.

What chemical reaction is Zinc undergoing in a alkaline battery?
In an alkaline battery zinc is giving up electrons, so it's being reduced.
What chemical changes involve breaking and making chemical bonds?
Breaking of bonds but also formation of new bonds.
Is adding HCl to Mg a physical change?
chemical because when you add the chemical together you get a reaction that transforms the substance into another one. if im wrong please update this answer because this question could be on your test
What type of energy does a fire use?
Chemical potential energy. Fire is a chemical reaction caused by heat Fuel and oxygen (usually) The fuel is combusted exothermically (ie giving off heat) with oxygen which is a chemical reaction. This causes surrounding fuel to heat up a react exothermically with the oxygen, propagating the fire.
How do you know that a chemical change is happening in the flask?
signs of a chemical reaction occurring include: -formation of a gas (bubbles) -change in color -transfer of energy (change in temperature, giving off light) -formation of a precipitate (if a solid forms out of solution)
