When elements form mixtures what will always be true about elements?
When elements form mixtures, they will never gain or lose electrical charge and stay exactly the same as they were before, as no chemical reaction has occured (i.e. no change in amount of neutrons)
Is a rock a compound or a mixture?
Rocks are mixtures because they can be made up of varying compounds and elements in varying amounts, and these substances do not mix chemically, but physically, still retaining there chemical properties.
Does sulfur in the mixture still have the properties of pure sulfur?
Yes. Any compound present in a mixture retains its own properties.
What is the difference between the way materials combine to form mixtures and the way elements combine to form molecules?
Properties change when molecules are formed. Properties, at least some of them, do not change in a mixture. Mixtures can be done in any proportion, molecules have an exact ratio of the elements in them. Hydrogen gas and oxygen gas can be mixed in a container in any amounts. 10 parts hydrogen to 3 parts oxygen or 15 parts oxygen to 7 parts hydrogen. They are still gases, colorless, odorless, etc. But if you strike a match the atoms combine in a ratio of 2 hydrogen to 1 oxygen and form water. If you collect it and cool it, the compound is liquid water. Obviously not the same properties.
What is a substance made up of two or more elements not combined chemically?
A couple of examples would be salt water and sugar water. The salt and sugar dissolve in the water, but still exist as smaller molecules (or in salt's case, as sodium and chlorine ions) among the water molecules.
Smallest particle of a compound that still retains it's properties?
The molecule is the smallest particle of a compound that retains its chemical properties. A molecule consists of two or more atoms bonded together. Each molecule has a unique set of properties determined by the types of atoms present and their arrangement.
Why do mixtures such as sugar and water lack a chemical formula?
Mixtures such as sugar and water do not have a chemical formula because they are composed of two or more substances physically combined, but not chemically bonded. Each substance retains its own chemical identity and properties in a mixture. A chemical formula is used to represent compounds, which are formed when elements chemically bond.
When elements combine to form compounds their properties change?
The chemical properties of atoms are significantly changed when they form compounds. When elements combine to form compounds it is called a chemical reaction. The compound is then a collection of molecules and each molecule has are still the same atoms as one started with, but the arrangement of the electrons in the atoms has changed.
What is compound mixture?
Briefly there are elements, mixtures & compound.elementsIt is simply consists one kind of element, it's the simplest structure and can be form into molecule or single atom (O2, N2 and ecetra)mixtureIt's simply consist of 2 or more kind of element that are physically mix or intermingle. the properties still remain like its component.compoundconsist of 2 or more elements that are bound together by a chemical effect or heating process. the properties is different from it's component.
What do you call a mixtures of two or more substances?
It is still a mixture
What Elements Compounds or Mixtures are found in fresh water in clouds?
Fresh water in clouds is pure H2O. As the rain falls, it will pick up some impurities from the air, but when it is still in the clouds, it is quite pure.
What is similar between homogeneous and heterogeneous?
both mixtures need atleast 2 components and at least one of the components has to be a liquid there are many other reasons
