How many grams of potassium chlorate will produce 112.5g of oxygen?

To calculate the amount of potassium chlorate needed to produce 112.5g of oxygen, you first need to determine the molar ratio between potassium chlorate and oxygen. Then, use this ratio to convert the grams of oxygen to grams of potassium chlorate using the molar masses of each compound.


What is the preparation of oxygen using potassium chlorate?

Oxygen can be prepared from potassium chlorate by heating it strongly until it decomposes into potassium chloride and oxygen gas. The reaction is 2KClO3 -> 2KCl + 3O2. The released oxygen can then be collected and used for various purposes.


How many grams of potassium chlorate decomposes to yield 30 grams of oxygen?

The molar mass of potassium chlorate (KClO3) is 122.55 g/mol. This means that 122.55 grams of potassium chlorate yield 3 moles of oxygen gas. To calculate the amount of potassium chlorate that decomposes to yield 30 grams of oxygen, you can set up a simple ratio using the molar masses.


How much oxygen gas in grams can be prepared from 86.8 g of potassium chlorate?

To calculate the amount of oxygen gas produced from potassium chlorate, use the balanced chemical equation for the decomposition of potassium chlorate: 2KClO3 -> 2KCl + 3O2. From the equation, every 2 moles of KClO3 produce 3 moles of O2. First, convert the given mass of KClO3 to moles, then use the mole ratio from the balanced equation to find the moles of O2 produced. Finally, convert moles of O2 to grams using its molar mass (32 g/mol).


What mass of potassium chlorate would contain 40.0g of oxygen?

To calculate the mass of potassium chlorate containing 40.0g of oxygen, first determine the molar mass of oxygen (16g/mol). Then, use the molecular formula of potassium chlorate (KClO3) to find the oxygen's molar ratio in KClO3 (1:3). Finally, calculate the mass of KClO3 using the molar mass and the molar ratio to find that approximately 186 grams of potassium chlorate contain 40.0g of oxygen.


Decomposition of potassium chlorate to potassium chloride?

Potassium chlorate can be decomposed into potassium chloride and oxygen gas by heating it to high temperatures. This process is typically carried out in a laboratory setting using a test tube or other heat-resistant container. The balanced chemical equation for this decomposition reaction is: 2KClO3 -> 2KCl + 3O2.


How many grams of potassium chlorate are needed to make 250.0ml of a 1.550M potassium chlorate?

To find the grams of potassium chlorate needed, you would first calculate the moles of potassium chlorate using the molarity and volume provided. Then, use the molar mass of potassium chlorate to convert moles to grams. So, the calculation would be: moles = Molarity x Volume (in liters), and then grams = moles x molar mass of potassium chlorate.


How do you produce Oxygen Gas in the lab?

Oxygen gas can be produced in the lab by heating a compound that contains oxygen, such as potassium chlorate, and collecting the gas released through a tube. Another method is through the electrolysis of water, where water is split into hydrogen and oxygen gases using an electric current.


How do you make oxygen in a lab?

Oxygen can be produced in a lab using a process called electrolysis, where water (H2O) is split into oxygen (O2) and hydrogen gas (H2) using an electric current. Another method is to heat a compound like potassium chlorate (KClO3) which breaks down into potassium chloride (KCl) and oxygen gas.


What are the laboratory preparation of oxygen using manganij di oxide?

To prepare oxygen in the laboratory using manganese dioxide, one can heat potassium chlorate in the presence of manganese dioxide as a catalyst. The reaction produces oxygen gas, which can be collected by displacement of water in an inverted gas jar. This method is commonly used in high school or introductory chemistry labs to demonstrate the preparation of oxygen.


The oxidation number of Cl in Potassium chlorate?

The oxidation number of Cl in potassium chlorate (KClO3) is +5. This is because the oxidation number of K is +1 and the oxidation number of O is -2. By using the sum of the oxidation numbers in the compound, the oxidation number of Cl can be calculated to be +5.


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
