What does MnO2 mean in a chemical equation?
It means you have some manganese(IV) oxide. This compound most often shows up in chemical equations as a catalyst. It is most popularly used as a catalyst in the decomposition of hydrogen peroxide (H2O2.) A catalyst speeds up a chemical reaction by lowering the reaction's activation energy. In the equation for a chemical reaction, the catalyst is written in superscript-small symbols above the "yield" arrow.
True or false in an equation a substance is shown to be in the gaseous state by placing an upward-pointing arrow after its formula?
True. In an equation, placing an upward-pointing arrow after the formula of a substance indicates that it is in the gaseous state.
What is the name of the arrow in a chemical equation?
The name of the arrow in a Chemical Equation is called the yield.
In a chemical equation the products are to the blank of the arrow and the reactants are to the blank?
In a chemical equation, the products are to the right of the arrow and the reactants are to the left.
Which arrow is used to indicate a reverse or backward reaction in a chemical equation?
The arrow that is used to indicate a reverse or backward reaction in a chemical equation is called a double-headed arrow.
What does Mn mean in above the arrow in a formula equation mean?
it means that manganese is a catalyst in the reaction
Where is a catalyst written in an equation?
A catalyst is typically written above the arrow in a chemical equation, indicating its role in speeding up the reaction without being consumed itself. It is not listed as a reactant or product in the equation.
What does MnO2 mean in a chemical equation?
It means you have some manganese(IV) oxide. This compound most often shows up in chemical equations as a catalyst. It is most popularly used as a catalyst in the decomposition of hydrogen peroxide (H2O2.) A catalyst speeds up a chemical reaction by lowering the reaction's activation energy. In the equation for a chemical reaction, the catalyst is written in superscript-small symbols above the "yield" arrow.
A chemical formula written over the arrow in a chemical equation signifies?
It is a catalyst/ inhibitor to the reaction. Of itself , it does NOT change, but only aids(changes the rate of the reaction Similarly if a physical component if placed their. e.g. CH3CH2OH + CH3COOH ==H^(+)==> CH3COOCH2CH3 + H2O Acid catalyst (H^(+)) to speed up the reaction. Usually sulphuric acid. or CaCO3 ==Heat==> CaO + CO2 ( Thermal decomposition). NB Catalyst speeds up the rate of reaction Inhibitor slows down the rate of reaction, because it may go TOO fast, and uncontrolled.
True or false in an equation a substance is shown to be in the gaseous state by placing an upward-pointing arrow after its formula?
True. In an equation, placing an upward-pointing arrow after the formula of a substance indicates that it is in the gaseous state.
What chemical equation term is used for the chemical formula to the right of the arrow?
You think probable to products of a chemical reaction.
What is the name of the arrow in a chemical equation?
The name of the arrow in a Chemical Equation is called the yield.
Why is a catalyst written above the arrow in a chemical equation rather than with the reactants?
A catalyst is written above the arrow in a chemical equation to show that it is not consumed in the reaction and thus does not appear in the overall stoichiometry of the reaction. This means that it does not take part in the reaction as a reactant or a product, but it still helps in speeding up the reaction. Placing it above the arrow helps to distinguish it from other reactants or products.
What is the small triangle above the horizontal arrow in a chemical equation?
It means heat was supplied to make the reaction occur.
What does a triangle over an arrow in a formula equation mean?
The symbol is referred to as "delta" and means that the reaction occurs under heating conditions.
Balance manganese dioxide and potassium chlorate?
Balance manganese dioxide and potassium chlorate is as follows . the formula for potassium chlorate is KClO3 and the one for manganese dioxide is MnO2.so, the reaction is :2 KClO3(s)-> 2 KCl(s)+3 O2(g).
Why is sunlight written above the arrow in the equation rather than on the other side?
beacause its sintific notation sais your mom
