Where did potassium's chemical symbol come from?
The original word for potassium in Latin is kalium. That is where you get K for the element , Potassium.
Can you separate potassium hydroxide?
No, potassium hydroxide cannot be easily separated back into its original components once it has been mixed together. It is a fully reacted compound.
Is the exploding of potassium metal in water a chemical change?
Yes, the exploding of potassium metal in water is a chemical change. This reaction involves the formation of new substances (potassium hydroxide and hydrogen gas) with different chemical properties than the original substances (potassium metal and water).
How does potassium become an ion?
When a potassium atom becomes an ion, the potassium atom donates one of its electrons, specifically the only electron in its valence shell, to another more electronegative atoms. The original potassium atom then becomes a potassium cation with formula K+.
Is potassium chlorate heated reversible?
Yes, when potassium chlorate (KClO3) is heated, it decomposes into potassium chloride (KCl) and oxygen gas (O2) through a reversible reaction. However, the reverse reaction of recombining potassium chloride and oxygen gas to form potassium chlorate is not spontaneous and typically requires additional energy input.
What happen if the potassium permanganate solution drop to the water and add of concentrated sulfuric acid?
When potassium permanganate solution is dropped into water, it dissolves and forms a purple solution. If concentrated sulfuric acid is then added, the manganese in potassium permanganate can be reduced to form a colorless compound. This reaction generates heat and can be exothermic. The resulting solution will likely be colorless or have a faint pink hue instead of the original purple color.
Why is the reaction between glycerol and potassium permanganate irreversible?
The reaction between glycerol and potassium permanganate is irreversible because it involves a complete change in the molecular structure of the reactants. Glycerol, an alcohol compound, is oxidized by potassium permanganate, resulting in the formation of different products, such as carbon dioxide, water, and manganese dioxide. Once these new products are formed, it is difficult to reverse the reaction and reform the original reactants.

Which membrane protein is responsible for restoring the original concentration of Na plus and K plus?
The sodium-potassium pump, also known as the Na+/K+-ATPase, is responsible for restoring the original concentration of sodium and potassium ions across the cell membrane. This pump actively transports three sodium ions out of the cell in exchange for two potassium ions pumped into the cell, using ATP energy to maintain the concentration gradients.
Is the exploding of potassium metal in water a chemical change?
Yes, the exploding of potassium metal in water is a chemical change. This reaction involves the formation of new substances (potassium hydroxide and hydrogen gas) with different chemical properties than the original substances (potassium metal and water).
How much potassium-40 would remain after three half lives?
Potassium 40 is an isotope with 19 protons (and electrons) and 21 neutrons. Potassium 40 accounts for around 0.012% of potassium and is fairly stable (half life of 1.25 billion years).Potassium 40 is an isotope with 19 protons (and electrons) and 21 neutrons.

Is heating potassium bicarbonate a chemical or physical change?
Heating potassium bicarbonate is a chemical change because it causes a decomposition reaction. This results in the formation of new substances (potassium carbonate, water, and carbon dioxide) that have different chemical properties than the original compound.
What is the half-life of potassium-40 if a potassium-40 sample starts with 50 atoms and 1.25 billion years later there are 25 atoms?
The half-life of potassium-40 is 1.25 billion years since half of the original sample decays in that time. With 50 atoms initially, having 25 atoms remaining after 1.25 billion years aligns with the expected decay pattern for a half-life.
How much aspartame does the one gram pack of Equal contain?
The ingredient list on their site does not list the amounts, but a general rule of thumb is that ingredients are listed according to the amounts in the product, from the greatest to the least. Here are the ingredient lists for several Equal products: Equal Original PACKETS: dextrose with maltodextrin, aspartame, acesulfame potassium Equal Original SPOONFUL/GRANULATED: maltodextrin, aspartame, acesulfame potassium Equal Classic TABLETS: lactose (from milk), aspartame, acesulfame potassium, cellulose gum, calcium stearate The two sweeteners in Equal are: Aspartame - a sweetening ingredient that is 200 times sweeter than sugar Acesulfame Potassium - a sweetening ingredient that is 200 times sweeter than sugar
