No, compounds and elements are not always solids. For example, hydrogen is a gas.
What else can I help you with?
Is it true a compound is always in the same physical state as its elements?
Depends what you mean - your question is not clear - but consider :- At STP Oxygen and Hydrogen are two elements in the gaseous physical state BUT their compound Water is in the liquid state. At STP Oxygen is gaseous and Iron is solid BUT their compound is Iron Oxide is solid. So the answer is no.
Are elements that make up a compound always present in the same proportions?
No, elements in a compound are not always present in the same proportions. The ratio of elements in a compound is determined by its chemical formula.
A given compound is always made of the same elements in the same?
A given compound is always made of the same elements in the same proportion.
What are the masses of elements in a compound always in?
a cmpound
What is always true about binary compound?
it has two elements
Is a yellow solid that always has the same properties and cannot be broken down an element or compound?
A yellow solid that always has the same properties and cannot be broken down is most likely an element. Elements are made up of only one type of atom and cannot be broken down into simpler substances by chemical means. Examples of yellow elements include sulfur and gold.
What elements might you find in an organic compound?
Always carbon and almost always hydrogen.
Is the amount of elements needed to make a compound always the same?
The proportions are always the same.
Does ice contain elements?
Ice itself is not composed of elements as it is a compound made up of water molecules in a solid state. However, the water molecules in ice are composed of hydrogen and oxygen atoms, which are elements.
Is a substance in which all the exact combinations of elements are always the same?
A substance in which the exact combination of elements is always the same, is called a compound.
Are the proportions of a compound fixed or not fixed?
The proportions of elements in a compound are fixed, meaning that a specific compound will always have the same ratio of elements by mass. This fixed ratio is determined by the chemical formula of the compound.
What do compounds always contain in exact ratios?
Compounds always contain elements in exact ratios, based on the chemical formula of the compound. This means that the elements are present in specific and consistent proportions in the compound.
