Does the speed of sound increase of decrease or remain the same when air temperature increases?
decrease because when temperature is low water is present in atmosphere which let sound to go fast
What happenes to the speed of a chemical reaction when a catalyst is present?
The speed of a chemical reaction may increase or decrease by the addition of a catalyst. In the synthesis of ammonia by Haber's process , Fe + Mo mixture acts as a catalyst which increases the formation of ammonia,here Fe + Mo mixture is positive catalyst(increases the speed of the reaction). The oxidation of chloroform (CHCl3) by air in presence of sunlight is retorted by the edition of 1% ethyl alcohol in to it. Here alcohol acts as a negative catalyst (decreases the speed of the reaction)to the oxidation of chloroform .
What is present after a chemical reaction?
That depends on the chemicals present before the chemical reaction and sometimes the conditions under which the chemical reaction occurred.
What is present in a solution in which a reaction is taking place but do not participate in the reaction?
spectator ions in a double replacement reaction
An increase in temperature causes a decrease in the amount of gas able to dissolve in a liquid solvent Why does this occur?
As temperature increases the mean kinetic energy of all particles present increase, allowing for the gases dissolved to evaporate more readily, as they are in a greater state of vibratory motion - that is they are present in a more gaseous form. Phase is determined by the extent of motion of particles, which is determined by the intermolecular forces acting between molecules. An increase in temperature will also increase the motion of dissolved particles by weakening the forces acting between the solute and solvent. This allows the dissolved gases to evaporate out of solution. Hence an increase in temperature corresponds to a decrease in the solubility of gases in liquids. Hope it helps. By Vibs
Does present value increase or decrease when the interest rate increases?
decrease
Why was there no increase in reaction with 8g compared to 4g of substrate?
Generally, if you increase a reagent and there is no increase in the reaction, then it is limited by the amount of another reagent present. For example, a mole of Sodium Hydrogen Carbonate will react with a mole of Acetic Acid. However, doubling the Acetic acid will not result in a greater reaction because it is limited by the amount of Sodium Hydrogen Carbonate present.
Does the speed of sound increase of decrease or remain the same when air temperature increases?
decrease because when temperature is low water is present in atmosphere which let sound to go fast
Effect of ionic strength on rate of reaction?
The rate of reaction basically depends on the product of charges of ions present in a solution. Since the compounds dissociate in a solution and forms cations and anions, so their product matters a lot. If the product of charges is positive ( i.e. one ion is +1 and other is +4 = +4 ), then the rate of reaction will increase automatically, higher the product faster will be the rate. Similarly, if the product of ions present in a solution is negative ( i.e. one ion is +1 and other is -3 = -3) then the rate of reaction will decrease. For those reactions in which neutral species are present and for which the product of charges will be zero, there will be no effect on the rate of reaction.
Does the present value of money increase as the number of years before the payment is received increases?
No, it should decrease, assuming the interest rate is the same.
What present of decrease fro me 250 to 225?
It is a 10% decrease
What may happen to the boiling point of a substance if there are impurities present. Explain in terms of the nature of impurities.?
it might decrease or increase depends on the impurities added.:D

Are the substances present before the reaction?
Substances that are present before the reaction are called "reactants" or "reagents".
