Determine Mole ratios in a balanced chemical equation?
put the coefficient of one substance over the coefficient of the other for example, in the reaction 3H2S + 2Al(OH)3 --> 6H2O + Al2S3 the mole ratio of H2S:H2O is 3:6 or 1/2.
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.
What is the balanced equation for the reaction of NaOH being added to hydrochloric acid?
HCl + NaOH = NaCl + H2O Acid + Base = Salt + Water
Is naoh plus hcl results in nacl plus h2o a chemical change?
Yes, species have traded partners and the chemical compositions have changed. A strong acid and a strong base have undergone a neutralization reaction and produced a salt( actually two species in solution ) and water.
What is the balanced equation for silver plus potassium nitrate?
Potassium nitrate is too stable and so is silver for these two species to react. There is thus no balanced equation.
How are ecological Competition coefficients measure?
Competition coefficients measure the effect of one species on another competing species.
What is the balanced ionic equation for when ammonium phosphate react with sodium hydroxide?
There is no reaction between these, because all species are soluble.
What is the balanced equation for the reaction that occurs when a student in a lab adds 150 ml of 1.00m AgNO3 solution to 100 ml of 1.00m K2CO3 solution.?
2AgNO3 + K2CO3 >> Ag2CO3 + 2KNO3 ( much more could be done with those numbers, but you did not ask for that ) ( Plus, I am not sure if Silver carbonate percipitates out of solution, so all those species could be dissasociated )
What does a chemical reaction show?
It shows the preservation of mass and of matter.

What is dissolving salt into water an example of?
No, this is not a redox reaction (or a chemical reaction at all) because no species gain/lose electrons in this process.
Define law of mass action?
The law of mass action states that the rate of a chemical reaction is directly proportional to the concentration of reacting species raised to their respective stoichiometric coefficients. In other words, the rate of a reaction is determined by the concentrations of the reactants involved. The law is used to express the relationship between the concentrations of reactants and products in equilibrium systems.
What is Competition Coefficients?
quantitative measures of the negative effects of an individual of one species on an individual of a second species; used to relate the size of one species-population to the size of the other; denoted á12 and á21
Reason why no reaction between Magnesium sulphate and hydrochloric acid?
MgSO4 is a stable salt, I think. Besides, this reaction would produce highly reactive H2SO4, so you would have four species in solution; perhaps some kind of equilibrium reaction. ( needs chemists edit )
What effect do keystone species have on an eccosystem?
A, they keep the populations of species balanced. Apex
