What else can I help you with?
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)
Are the constituent in a mixture present in fixed proportions?
No, the constituents in a mixture are not present in fixed proportions. Mixtures can vary in composition, meaning the amounts of each component can change while still retaining the properties of the individual substances. This flexibility differentiates mixtures from pure substances, which have a uniform composition.
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.
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.
Can you still recognize the components of the mixture why?
Yes, the components of a mixture can often still be recognized because they retain their individual properties and characteristics. Unlike compounds, where elements are chemically bonded together and lose their distinct identities, mixtures consist of physically combined substances that can usually be separated by physical means. This allows for the identification of each component within the mixture. For example, in a salad, you can still see and taste the individual ingredients such as lettuce, tomatoes, and cucumbers.
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.
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 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
