What happens when potassium react to water?
When potassium reacts with water the potassium burns a bright purple light, a gas is given off with a hissing noise and the potassium rockets around the surface of the water because it floats.
Potassium reacts with water to produce hydrogen gas and potassium hydroxide and releases 160 kJ of heat energy How much heat would be released if 120 g of potassium reacts?
The molar mass of potassium is 39.1 g/mol. Therefore, 120 g of potassium would be 120/39.1 = 3.07 moles. Given that 160 kJ of heat is released per mole of potassium, the total heat released when 3.07 moles of potassium react is 3.07 * 160 kJ = 491.2 kJ.
When potassium carbonate is heat what gas is given off?
When potassium carbonate is heated, carbon dioxide gas is given off. Potassium carbonate decomposes to form potassium oxide and carbon dioxide.
What gas is given off when magnesium reacts with sulfuric acid?
Hydrogen gas is given off when magnesium reacts with sulfuric acid.
Which gas is given off when potassium permanganate is broken down?
Oxygen gas is given off when potassium permanganate is broken down. Potassium permanganate decomposes into manganese dioxide, potassium hydroxide, and oxygen gas when heated.

A science teacher added the reactive metal potassium to water. The metal formed a ball shapeon the surface of the water and the gas given off burned with a pop. Name the gas given off.?
The gas given off is hydrogen gas. When potassium reacts with water, it forms potassium hydroxide and hydrogen gas. The pop sound is due to the ignition of the hydrogen gas.

What is the mark used for?
It is used to estimate the population of a species in an ecosystem. It is an educated guess based on the data you collect because it is impossible to know exactly how many organisms there are in a given area.

What is given off when iron reacts with oxygen?
ironoxide
What is the trap-mark-release method used for?
