When the equation KClO3(s) KCl(s) O2(g) is balanced the coefficient of KClO3 is?
The balanced equation for the decomposition of potassium chlorate (KClO3) is 2 KClO3(s) → 2 KCl(s) + 3 O2(g). Therefore, the coefficient of KClO3 in the balanced equation is 2.
What changes occurs when KClO3 is heated in the presence of MnO2?
When KClO3 is heated in the presence of MnO2, it undergoes a decomposition reaction to produce potassium chloride (KCl) and oxygen gas (O2). The manganese dioxide (MnO2) acts as a catalyst, speeding up the reaction but remains unchanged itself.
What is the change in entropy (S) when an icicle melts at 2 and degC?
Delta S= Delta H
What is the reaction between h2so3 plus kclo3 equals?
The reaction between H2SO3 and KClO3 does not occur. H2SO3 is a weak acid, and KClO3 is a salt. There is no precipitation, gas evolution, or significant heat release that would indicate a chemical reaction taking place between these two substances.
What equation is used to calculate the free energy change a reaction?
Delta G (written triangle G) = Delta H -T Delta S
When the equation KClO3(s) KCl(s) O2(g) is balanced the coefficient of KClO3 is?
The balanced equation for the decomposition of potassium chlorate (KClO3) is 2 KClO3(s) → 2 KCl(s) + 3 O2(g). Therefore, the coefficient of KClO3 in the balanced equation is 2.
Write the decomposition of H2CO3 and KClO3?
2KClO3(s)->2KCl(s)+3O2(g)
How many moles of KClO3 on decomposition give 1 mole of oxygen?
2 grams of Oxygen can be obtained from 5 grams of KClO3 (only if the "CL" means "Cl", which is Chlorine! Remember that only the first letter of the atomic symbol is capitalized.)
What is the formula for potassium chlorate?
The formula for potassium chlorate is KClO3.
What is delta S in the equation delta G delta H-T delta S?
Delta S represents the change in entropy of a system. In the equation delta G = delta H - T delta S, it is used to determine the contribution of entropy to the overall change in Gibbs free energy. A negative delta S value suggests a decrease in the disorder of a system.
Write balanced equation for KCIO3 yields KCL O2 and unbalanced reaction?
The actual formula is KClO3 (with a lowercase L) Balanced equation: 2KClO3 --> 2KCl + 3O2
What is the percent of oxygen in KClO3?
The percent of oxygen in KClO3 is 48.4%. This can be calculated by dividing the molar mass of oxygen in KClO3 (48 g/mol) by the molar mass of KClO3 (122.55 g/mol) and multiplying by 100%.
What is the atomicity of KClO3?
The atomicity of KClO3 is one, which means that in one molecule of KClO3, there is one atom each of potassium (K), chlorine (Cl), and oxygen (O).
Symbol for potassium chlorate?
The formula (not symbol) is KClO3
What is delta S in the equation delta G delta H - T delta S?
The change in enthalpy between products and reactants in a reaction
What is the formula for converting potassium chlorate into oxygen?
The chemical equation for converting potassium chlorate (KClO3) into oxygen (O2) is: 2KClO3 (s) -> 2KCl (s) + 3O2 (g). When heated, potassium chlorate decomposes into potassium chloride and oxygen gas.
What is the balanced chemical equation for potassium chlorate?
The chemical formula (not equation) is KClO3
