When potassium permanganate is dissovled in water and heated what is the color of the disillate and original solution?

The original solution is an intense violet color because it contains dissolved potassium permanganate. The distillate is clear (colorless) because only the water distills and the potassium permanganate is left behind, as it is non-volatile.

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.
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+.
A potassium 40 sample starts with 50 atoms and 1.25 billion years later there are 25 atoms What is the half life of potassium 40?
1.25 billion years: 25/50 or half the original atoms have disintegrated in 1.25 billion years, and that is the definition of half life.
What materials are in dynamite?
Original, it was nitroglycerin packed in sawdust. This was because it was to unstable. This made it safer to use. Now, potassium nitrate of ammonium nitrate are used more commonly, because they are even more stable.
Is potassium chlorate heated reversible?
Nope, when the heat melts it, the atoms change and produce oxygen, so it cannot re-cool into its original powder form because it's atomic structure has already changed.
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?
Sodium potassium pump is responsible for restoring the original concentration of Na plus and K plus.
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.

How does the sodium potassium pump help with your homeostasis?
When a nerve cell (neuron) or muscle cell react, they do so by a process called depolarization. Before depolarization, the inside of the cell is slightly negative and the outside is slightly positive. During depolarization, sodium ions rush into the cell while potassium channels leak out. This reverses the original polarization and now the cell is said to be depolarized. The sodium/potassium pump helps reverse this back to its original polarized state so the cell can react again.

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
What was gun powder made from?
Black powder, the original form of gunpowder, was made from a combination of potassium nitrate (also known as saltpeter), charcoal, and sulfur in a 15:3:2 ratio.
Describe 6 steps to the sodium potassium pump?
1. Sodium Ionsbind to the protine on the inside of the membrane. 2. ATP is phosphorilated into ADP. The phosphate is transferred to the protin and the conformation is changed. 3. The Sodium is put into th external space and the Potassium ions bind to the protein. 4. The phosphate group is lost.5. This causes the protein to snap ack to its original comformation. 6. The potassium ion diffuses into the cell and binds into its transmembrain domain.
