What gas is produced when potassium hydroxide and calcium carbonate are mixed?
Those two compounds do NOT react at all.
Two compounds that have the same molecular formula but different structural formulas are?
Two compounds that have the same molecular formula but different structural formulas are isomers of each other.
What if in a reaction the ions of two compounds exchange places in aqueous solution to form two new compounds this reaction is called?
An acid-base reaction.
Will sodium and sulfur form ionic compounds?
Yes. These two elements alone will form ionic sodium sulfide, and together with oxygen they can form several other ionic compounds such as Na2SO4.
Does helium form compounds?
Answer:Helium is an inert gas and does not easily form any compounds, in fact there are no known compounds. (It's valence shell is full to capacity, 1s2.) In an electrical discharge it can form metastable 'compounds' called excimers (short for excited dimers) with tungsten, iodine, sulfur, fluorine, phosphorus and sulfur. These are short lived entities, lifetime typically measured in nanoseconds, that are formed by excited helium atoms.There is some thought that helium may react like argon and form helium fluorohydride (HHeF) similar to the argon compound HArF.The curious investigator could use the link below to surf to the Wikipedia post on the compounds of helium. It's only two paragraphs long and easy to read. Why not pull out the stops and go for it?
Will sodium bicarbonate react with sodium chloride to form sodium hydroxide?
No. In fact, those two compounds will not react at all.
What two families of elements react easily with each other to form compounds?
Alkali metals and halogens.
Are NaCl and SiO2 example of compounds or mixtures?
These two compounds form a mixture because they can not react with each other under normal conditions.
When two or more different elements react together they form a?
They form a compound.
What a two or more substances that are combined chemically?
Two or more substances which can chemically react form new chemicals after the reaction.1. If these chemicals react they form new compounds.2. Without a chemical reaction they form a mixture.Read more: What_is_two_or_more_substance_are_combined
When two or more different elements unite chemically they form what?
Compounds.
Why is the ternary compound also a synthesis reaction?
Two compounds combine to form a new compound. When two substances react to form one new substance, it is a synthesis reaction.
How can you tell if two compounds will mix or react?
You can tell if two compounds will react by looking at the solubility rules. If a reaction were to happen it would make HNO3 and Na2SO4.
Do alumium chloride react with sodium chloride?
These two compounds do not react each other.
Could a mixture be made up only elements and no compounds?
Yes that is possible. Mixtures can have two or more elements, two or more compounds, or both. For instance, you could have a mixture of noble gases or a mixture of two different elemental metals. The thing is that the elements have to be stable so that they would not react among themselves and form a compound.
What combines to form compounds?
Atoms of elements combine to form compounds. A chemical compound is a pure chemical substance consisting of two or more different chemical elements that can be separated into simpler substances.
2 or more substances form what?
Two or more substances may combine chemically under certain conditions and form compounds.
