What is the type of chemical reaction between Sodium Thiosulphate reacts and hydrochloric acid and what is the balanced equation?
The reaction between sodium thiosulfate and hydrochloric acid is a redox reaction, where the sulfur in thiosulfate changes oxidation state. The balanced equation for this reaction is: 2Na2S2O3 + 2HCl -> 2NaCl + SO2 + S + H2O.
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 can you identify a redox reaction in a chemical equation?
A redox reaction can be identified in a chemical equation by observing the transfer of electrons between reactants. Look for changes in oxidation states of elements and the presence of both reduction and oxidation half-reactions.
Which element undergoes Oxidation in k2cro4 na2so3 hcl-kcl na2so4 crcl3 h2o?
Chromium undergoes oxidation in the given chemical equation. In this reaction, chromium changes from a +6 oxidation state to a +3 oxidation state, indicating that it has lost electrons and undergone oxidation.
What is the oxidation number of sulphur in the equation of combustion of H2S?
The oxidation number of sulphur in H2S is 2.

How is an oxidation half-reaction written using the reduction potential chart?
Reversing the equation gives the oxidation half reaction. Doing this changes the sign on the voltage, not the magnitude.

Is N2O4 ---- 2NO2 a redox reaction?
Yes, the reaction N2O4 -> 2NO2 is a redox reaction because nitrogen changes its oxidation state from +4 to +2, while oxygen changes its oxidation state from -2 to 0. This indicates a transfer of electrons between the reactants.
Is photosynthesis a chemcal change?
Yes, the balanced chemical equation is as follows: 6CO2 + 6H2O yeilds (or changes to) C6H12O2 + 6O2.
What can NEVER change these to make the equation balanced?
Changing subscripts in chemical formulas should never be done to balance a chemical equation because it changes the identity of the compounds involved. Instead, coefficients should be adjusted to balance the equation without altering the chemical formulas.
What are the different ways that the stimulation indicates when equation is balanced?
In a simulation, the indication that an equation is balanced can be shown through several methods. Commonly, visual cues such as color changes or animations may signal equilibrium. Additionally, numerical indicators or alerts might display when reactants and products are in equal proportions. Lastly, a confirmation message or a checkmark could signify that the equation meets the necessary balance criteria.
What accounts for the changes in oxidation number?
Changes in oxidation number occur due to the transfer of electrons between atoms during chemical reactions. When an atom loses or gains electrons, its oxidation number changes. This transfer of electrons leads to the formation of ions or new chemical bonds, resulting in different oxidation states for the atoms involved.
What is the oxidation number of carbon in carbonate?
The oxidation number of carbon in carbonate (CO3^2-) is +4. In the carbonate ion, each oxygen atom has an oxidation number of -2, so the overall charge of the ion is -2. This means the oxidation number of carbon must be +4 to balance the charges in the compound.
