Why do sodium and potassium need to be stored in oil?
because they react to oxygen
What metal is stored in oil?
Group 1 metals are stored under oil because they are so reactive, they will react with the oxygen in the air if you leave them unprotected, but will also react with water, therefore they need to be stored in oil.
Why is there a need to clean the area where you will do the paraffin casting?
To avoid cross contamination.
Is it safe to rinse off sodium hydroxide from your body using water?
If you get sodium hydroxide on your body you should rinse it off as fast as possible and not wait for an answer on the internet! That stuff is bad for you. You should stand under the shower. If you need to ask such a question, you have no business working with sodium hydroxide or anything else with a pH of 14.
Do you need a prescription for sodium chloride?
No you do not it is table salt

Why do sodium need to be stored in oil?
Because they are highly reactive as they react with oxygen and moisture with self ignition (burning flames) even at room temperature.
How do you convert 5 kg of paraffin to liters?
You need to know the density of the paraffin. Density is defined by unit of mass per unit of volume. Paraffin oil has a density of approximately 0.8 gm per cubic cm. Paraffin wax slightly more at 0.9 gm per cubic cm.
What solid is lighter than water but heavier than oil?
That is imposible ======================= Thank you. Now go to your room and study your spelling and punctuation lesson. What we need is a solid with a density less than 1 gm/cm3, and then an oil with a density less than that of the solid we found. Here are a couple of solids that float on water: -- Paraffin wax . . . 0.8 to 0.9 -- Sodium . . . 0.968 The question doesn't specify a particular type of oil. Here are a few I found that are lighter than water, paraffin, and sodium, along with their densities: -- Crude, 48° API . . . . 0.79 -- Crude, Texas . . . . 0.873 -- Vehicle gasoline . . 0.737 -- Kerosene . . . . . . 0.817 -- Olive oil . . . . . . . 0.80 to 0.92 If you add any of these liquids to a tall glass of water, they will float on top of it, and a lump of paraffin or sodium will float at the level where the oil and water meet. (Don't try this at home, at least not with sodium !)
How do you remove liquid paraffin from your hair?
If you get liquid paraffin in your hair you will need to find a sulfate shampoo to remove it. Organix and Cream of Nature are two brands of sulfate shampoos.
Do guinea pigs need sodium?
yes they do need sodium
Do plants need sodium to grow?
No, plants do not need sodium to grow. They need protein to grow.
Why do fuels need to be stored safely?
Fuels need to be stored because they are flammable.
Do metals need to be stored in sealed containers for safety?
There are many different kinds of metals, and they have different storage requirements. Mercury should be stored in a sealed container because it is a toxic liquid, and should not be allowed to spill accidentally; there could also be a very small amount of evaporation. Some metals such as sodium, lithium, or potassium (in their pure, metallic state) are highly reactive and need to be stored not only in a sealed container, but under oil - not water - because they react violently with water or with air. Many familiar metals such as iron, lead, zinc, tin, copper, gold, aluminum, etc., are quite stable and do not need to be stored in containers, sealed or otherwise - in fact, many containers are made from these metals.
Do plants need sodium and why?
No. Sodium is salt and it will kill a plant.
