When potassium chloride and sugar is combined with heat and oxygen and expanding gases it produces an effective rocket what?
The reaction between potassium chloride and sugar, when ignited with heat and oxygen, produces gases like carbon dioxide and potassium chlorate. These gases generate pressure within a confined space, propelling the rocket forward. The potassium chlorate acts as an oxidizer, providing the necessary oxygen for combustion to occur rapidly and efficiently.
How can the rate of thermal decomposition of potassium chlorate be increased?
The rate of thermal decomposition of potassium chlorate can be increased by adding a catalyst, such as manganese dioxide, to lower the activation energy required for the reaction to occur. Increasing the temperature can also accelerate the rate of decomposition by supplying more energy to break the bonds in the compound.
In heating the mixture of potassium chlorate and manganese dioxide what is the role of the manganese dioxide?
Manganese dioxide acts as a catalyst in the reaction, facilitating the decomposition of potassium chlorate into potassium chloride and oxygen gas. Manganese dioxide lowers the activation energy required for the reaction to occur, making the process more efficient and accelerating the release of oxygen gas.
What happen when heated mno2 and kclo3?
When manganese dioxide (MnO₂) is heated with potassium chlorate (KClO₃), it acts as a catalyst in the decomposition of potassium chlorate. The heat causes KClO₃ to break down into potassium chloride (KCl) and oxygen gas (O₂). The presence of MnO₂ speeds up this reaction, allowing the decomposition to occur at a lower temperature. The overall reaction is: 2 KClO₃ → 2 KCl + 3 O₂.
What happens when heating potassium chlorate?
When heating potassium chlorate, it decomposes to form potassium chloride and oxygen gas. The reaction is catalyzed by heat and may be vigorous, resulting in the release of oxygen gas and leaving behind a residue of potassium chloride.
How many moles of O2 is made with 3 grams of potassium chlorate?
If the reaction equation is KClO4 -> KCl + 2 O2, as will occur at sufficiently high temperature, 2 moles of O2 will form from each gram formula mass of KClO4. This formula unit mass has the value 138.55; therefore, the number of moles of diatomic oxygen formed will be 2(3/138.55), or about 4 X 10-2 moles. If the integer 3 is considered exact, more significant digits are justified, and the answer can be better approximated as 4.3306 X 10-2
Which of the 7 continents do the most violent tornadoes occur?
The most violent tornadoes generally occur in North America.
How does a match store chemical energy?
A match stores chemical energy through the chemical reactions that occur when it is struck against a rough surface, igniting the match head. The match head contains chemicals like sulfur, phosphorus, and potassium chlorate, which react to produce heat and light.
Does the most violent shaking occur at the epicenter?
Yes
When do most violent tornadoes happen?
Most violent tornadoes (F4 and F5) occur in the months of March-June.
What do you get when you mix Potassium Sulfate with Ammonium Nitrate?
No reaction will occur between Potassium Sulfate and Ammonium Nitrate.
What does pure francium do with water?
Very probable a very violent occur.
