When heated mercury oxide produces oxygen plus mercury. What would be the combined mass of oxeyn and mercury if 20 g of mercury oxide were heated?
When 20 g of mercury oxide is heated, it will decompose into oxygen and mercury. The combined mass of oxygen and mercury will still be 20 g, as no mass is lost or gained in a chemical reaction according to the Law of Conservation of Mass.
What happens when mercury reacts with gold?
When mercury reacts with gold, it forms an amalgam, which is a mixture of the two metals. This reaction can occur at room temperature and is reversible. The amalgam can be separated by heating, allowing the mercury to evaporate and leaving behind the gold.
What happens to the mass of gold when a jeweler melts the gold to make jewelry?
When a jeweler melts gold to make jewelry, the mass of the gold remains the same. This is due to the law of conservation of mass, which states that mass is neither created nor destroyed during a chemical reaction or change in state. The gold simply changes from a solid to a liquid state.
Can you get the gold from pour mercury?
Mercury and gold are two different elements. There is no mercury in gold and there is no gold in mercury. If there is some gold mixed in with the mercury to begin with, then there are ways to separate it out. If there is no gold in the mercury to begin with, then there's no way to get any gold out of it.
What chemical reaction occurs when ammonium dichromate and mercury thiocyanate are combined?
When ammonium dichromate and mercury thiocyanate are combined, a chemical reaction called a decomposition reaction occurs. This reaction produces a visually striking effect known as the "Pharaoh's serpent" or "Pharaoh's snake," where a dark, coiling mass of solid material is formed.
What is the reaction if you add mercury to the gold?
You waste your money.
How does Lavoisier's experiment with mercury show the law of conservation of mass?
Lavoisier's experiment with mercury involved heating mercury in a closed system and observing that the total mass remained constant before and after the reaction. This demonstrated that no mass was lost or gained during the process, supporting the law of conservation of mass, which states that mass is neither created nor destroyed in a chemical reaction.

Why shouldn't you expose gold to mercury?
Exposing gold to mercury can result in a chemical reaction that forms an amalgam, causing the gold to dissolve or lose its integrity. This process can tarnish the gold's appearance and potentially weaken its structure. Additionally, exposure to mercury poses health risks due to its toxic nature.
What word would you use to describe HgO in the reaction that Lavoisier is used to show conservation of mass?
The word to describe HgO in Lavoisier's reaction demonstrating the conservation of mass is "reactant." In this reaction, mercury(II) oxide (HgO) decomposes upon heating into mercury (Hg) and oxygen gas (O2). Lavoisier's experiment illustrated that the total mass of the reactants (HgO) equals the total mass of the products (Hg and O2), thereby confirming the principle of conservation of mass.

Calculating Mercury in Mercury oxide by gravimetric analysis?
First take the mercury oxide and heat it so that it decomposes completely. This will drive off the oxygen gas and leave you with elemental mercury. Record the exact mass of the mercury that you have left at the end of the reaction. Divide this mass of mercury by the original mass of your mercury oxide sample and multiply by 100. This will be the percent mercury by mass in your original sample.
What is mercuarys mass?
1026.302 this is the mass of mercury 1026.302 this is the mass of mercury

What is mercury's mass in kilogram's?
Mercury's mass is 0.33x1024kg.
