What else can I help you with?
Will an increased temp and an increased concentration speed up a chemical reaction?
Generally, yes. Unless the product of the reaction should be ammonia for example, where a decreased temperature is needed. A catalyst from the transition metals will speed up a reaction too, for example a nickel catalyst in the process of the hydrogenation of margerine as it lowers the activation energy needed for the reaction to start. Increased pressure will also speed up the reaction, no matter what reaction is occurring.
What are the compounds produced by the reaction C4H8 and HCl?
If the C4H8 compound is butene-1 or -2 or 2-methylpropene, the product is one of the chlorobutanes with general formula C4H9Cl. If the C4H8 compound is cyclobutane, there is no reaction at standard temperature and pressure.
What happens when iron is dipped in copper sulphate solution and why?
When Iron metal is dipped into a solution of copper sulfate a REDOX reaction occurs in which the Copper is reduced (gains electrons) and the iron is oxidised (loses electrons). When this happens, the iron metal becomes iron ions and the copper ions in the solution become copper metal. Cu2+(aq) + 2e- --> Cu(s) Fe(s) -->Fe2+(aq) + 2e- This occurs because the iron is a more active metal than copper, and as a general rule of thumb, a more reactive metal will displace a less reactive metal from solution. This principle underlies the action of the sacrificial electrode.
When looking at a chemical reaction how do you know what the reactants and products are?
In an equation the reactants are the on the left of the arrow, and the products are on the right. For example if you had the following equation: 2H2 + O2 => 2H2O 2H and O will be the reactants and H2O is the product.
What are the products of H2O?
The products of the chemical reaction involving water (H2O) can vary depending on the conditions. In general, when water undergoes electrolysis, it can produce hydrogen gas (H2) at the cathode and oxygen gas (O2) at the anode.
What are the elements or compounds that are produced by a chemical reaction?
The general term is "products", intuitively enough.
What in general terms does a chemical equation indicate?
A chemical equation is the representation of a chemical reaction.
Reaction the reales energy are called?
The general term for a chemical reaction that releases heat is an exothermic reaction.
What is paper burning an example of?
A chemical reaction, and also a reaction in general.
What is the general formula of a chemical equation?
The general formula of a chemical equation is: Reactants → Products It represents the transformation of reactant substances into product substances during a chemical reaction.
What is fecl3 naoh general reaction type?
The general reaction type between FeCl3 and NaOH is a double displacement reaction. This reaction results in the formation of Fe(OH)3, a precipitate, and NaCl, which remains in solution.
What is a general chemical equation for an endothermic double replacement reaction?
The general chemical equation for an endothermic double replacement reaction is AB + CD → AC + BD, where energy is absorbed from the surroundings. This type of reaction usually occurs in the presence of heat or other sources of energy to facilitate the breaking and reforming of chemical bonds.
What is the chemical weathering symbol equation?
A general equation doesn't exist; this depends on type of the chemical reaction involved.
What general terms does a chemical equation indicate?
Chemical formulas of reactants and products; number of molecules involved in the reaction.
How would cooling down a solution change reaction time?
In general, cooling a solution slows the reaction. You can use the Arrhenius equation to figure out what effect a given temperature will have on a particular reaction (you'll need to know the activation energy).
What is the name of a chemical whose presence allows two other chemicals to react with each other?
There is no chemical of that sort. The chemical general name for the substance which speeds up the reaction is known as a catalyst.
What is reactant that remains when perticular chemical reaction has finished called?
The general term used is 'products'
