What else can I help you with?
Which of the following substances does not produce oxygen gas through decomposition: water, hydrogen peroxide, or potassium chlorate?
Water does not produce oxygen gas through decomposition. Hydrogen peroxide and potassium chlorate do produce oxygen gas when they decompose.
when potassium is added to water what causes explosion?
When potassium is added to water, it reacts exothermically with the water to produce potassium hydroxide and hydrogen gas. The rapid production of hydrogen gas in the reaction causes an explosion due to the build-up of pressure from the gas release.
What are two differences that you would see between the reaction of lithium with water and that of potassium with water?
One key difference is the rate of reaction - potassium will react more vigorously and produce more heat compared to lithium. Another difference is that the reaction of potassium with water will produce more hydrogen gas compared to lithium's reaction.
Does potassium blow up in water?
Potassium reacts vigorously with water to produce potassium hydroxide and hydrogen gas. This reaction releases a lot of heat and hydrogen gas, which can ignite, resulting in a flame or explosion. Therefore, it is not safe to put potassium in water.
How much potassium chlorate should be heated to produce 2.24 L of oxygen at NTP?
1 mole of potassium chlorate produces 3 moles of oxygen gas when heated, or 1 mole of potassium chlorate produces 1.344 L of oxygen gas at NTP. To produce 2.24 L of oxygen gas, you would need about 1.67 moles of potassium chlorate.
What gas is made when potassium reacts with water?
Potassium reacts with water to produce potassium hydroxide (KOH) and hydrogen gas (H2).

What two substances can produce a gas?
Actually there are several possible answers to that question. Sodium and water produce a gas (hydrogen). Potassium cyanide and hydrochloric acid produce a gas (cyanogen). Etc.
What is occurring when a piece of potassium metal ignites in a beaker of water?
The potassium reacts with water to produce potassium hydroxide, hydrogen gas, and large amounts of heat. The heat ignites the hydrogen which in turn ignites the potassium.
How do you produce water gas?
boil some water and you would be produce water vapour or water gas as it evaporates
Does potassium blow up in water?
Potassium reacts vigorously with water to produce potassium hydroxide and hydrogen gas. This reaction releases a lot of heat and hydrogen gas, which can ignite, resulting in a flame or explosion. Therefore, it is not safe to put potassium in water.
Does potassium chloride produce hydrogen gas?
No, potassium chloride does not produce hydrogen gas when it reacts with water or any other substances. Potassium chloride is a salt compound and does not contain the elements required to produce hydrogen gas (e.g., hydrogen or oxygen).
How much potassium chlorate should be heated to produce 2.24 L of oxygen at NTP?
1 mole of potassium chlorate produces 3 moles of oxygen gas when heated, or 1 mole of potassium chlorate produces 1.344 L of oxygen gas at NTP. To produce 2.24 L of oxygen gas, you would need about 1.67 moles of potassium chlorate.
Why does potassium metal not collect at the cathode when aqueous solution of potassium hydrochloride is electrolyzed?
The reduction of hydrogen from water to produce hydrogen gas occurs at a lower electrical potential difference than the reduction of potassium ions to potassium metal. In even a concentrated aqueous solution, the supply of water present is usually adequate for this reaction to consume all the available electric current. Also, any small amount of potassium metal that might form would react very rapidly with water to release hydrogen gas.
What will happen when potassium and water together what kind of changes?
When potassium metal and water are mixed, a chemical reaction occurs. This exothermic reaction produces hydrogen gas and potassium hydroxide, which dissolves in the remaining water. This reaction can be vigorous and produce light, heat and sound.
