What else can I help you with?
What shows the relationship between the reactants and products in a chemical reaction?
the coefficients of a balanced reaction
What is the reaction sulfur plus oxygen gives sulfur dioxide?
The reaction between sulfur and oxygen forms sulfur dioxide, which is a chemical compound composed of sulfur and oxygen atoms. This reaction is exothermic, meaning it releases heat energy. The balanced chemical equation for this reaction is: 2S(s) + 3O2(g) → 2SO2(g).
What is the balanced chemical reaction between Zn s NaOH aq?
There's two possible reactions Zink with solid NaOH gives double salt Zn + 2NaOH --t--> Na2ZnO2 + H2 And I Think you need the other one: Zink with NaOH(aq) gives the complex salt: Zn + 2NaOH + 2H2O --> Na2[Zn(OH)4] + H2
Reaction of zinc sulphate with potassium ferro cyanide?
The reaction between zinc sulfate and potassium ferrocyanide will produce a white precipitate of zinc ferrocyanide. This reaction is a double displacement reaction in which the zinc ion from zinc sulfate replaces the potassium ion in potassium ferrocyanide. The balanced chemical equation for this reaction is ZnSO4 + K4[Fe(CN)6] -> Zn[Fe(CN)6] + 4K2SO4.
Reaction of magnesium with oxygen?
Magnesium is a reactive metal in groupe two of the periodic table and reacts with oxygen gas in group six to produce Magnesium Oxide. The reaction is as follows: 2Mg + O2 gives 2MgO
What are three things that show evidence of a chemical reaction?
There are five things:Color changeodorstate change (from liquid to solid, liquid to gas, etc...),gives off at precipitatea temperature change
How is thermochemical equation different from a balanced chemical equation?
A thermochemical equation includes information about the energy changes associated with a chemical reaction, such as enthalpy changes. A balanced chemical equation shows the reactants and products involved in a chemical reaction in their correct proportions. While a balanced chemical equation gives the stoichiometry of the reaction, a thermochemical equation provides additional information about the heat flow during the reaction.
How is the process of converting kiwi in plastic-ware evidence of a chemical reaction?
It gives evidence of a chemical reaction because it's molecules have changed to make something new also because it looks very different from how it looked before.
A chemical reaction that gives off heat is most likely to be what?
An endothermic reaction is one that consumes heat.
What term is used for the type of chemical reaction that gives out heat energy?
Exothermic reaction gives free heat (energy).
When a chemical reaction takes in more energy than it gives off it becomes what?
When a chemical reaction takes in more energy than it gives off, it becomes an endothermic reaction. In an endothermic reaction, energy is absorbed from the surroundings in the form of heat.
What is the name of a chemical reaction that gives out energy?
A chemical reaction that produces energy is said to be exothermic. In comparison, if it consumes energy it is endothermic.
What is the proper name for a chemical reaction that gives out heat?
combustion
What term is used 4 the type of chemical reaction that gives out heat energy?
Exothermic reaction gives free heat (energy).
What is the chemical reaction for the formation of rubber?
The type of chemical reaction that takes place through the formation of the rubber is called the mechano-chemical reaction. Through this, it gives the end product a three dimensional structure.
What is a chemical reaction gives off heat called?
exothermic reactions-gives off heat
If a substance changes its color and gives off a gas when heated is it a compound?
Yes, if a substance changes its color and gives off a gas when heated, it is likely a compound undergoing a chemical reaction. The change in color and evolution of gas suggest that new substances are being formed through chemical bonds breaking and forming.
