What else can I help you with?
The change in enthalpy that accompanies the formation of a compound from its elements?
The energy change that happens when a substance forms from its elements (APEX)
Do all pure samples of a given compound have the same percent composition?
A compound is a combination of two or more elements. These elements join together based on their molecular bonds. No two elements combine in the same percentage.
A great deal of energy is produced when an ionic compound is formed?
False. Formation of a compound is usually exothermic because a Noble Gas configuration forms around each atom. Therefore energy is given off during formation, and the atoms in the compound are more stable.
Is calcium oxygen an compound?
As given in the question, it is two separate elements. However, the two elements do combine to form the compound 'Calcium oxide', with the formula ' CaO'. CaO ( calcium oxide) is commonly known as 'Lime/Quicklime').
Is compound made up of identical particles?
No, a compound is made up of two or more different elements that are chemically bonded together in a fixed ratio. This distinguishes compounds from elements, which are composed of identical particles.
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.
The change in enthalpy that accompanies the formation of a compound from its elements?
The energy change that happens when a substance forms from its elements (APEX)
A given compound can be decomposed into two substances What are these substances?
The two substances are the products of the decomposition reaction. They are formed by breaking the bonds within the compound to create new compounds or elements. The specific substances produced depend on the chemical properties of the original compound.
Do all pure samples of a given compound have the same percent composition?
A compound is a combination of two or more elements. These elements join together based on their molecular bonds. No two elements combine in the same percentage.

What is heat of reaction of Diphosphorus Pentasulfide?
If you wanted to, you could ask what the heat of formation is of a given compound such as diphosphorus pentasulfide, but if you want to know about a heat of reaction, you have to specify a reaction. A compound is not a reaction.
Is compound made up of identical particles?
No, a compound is made up of two or more different elements that are chemically bonded together in a fixed ratio. This distinguishes compounds from elements, which are composed of identical particles.
Which pair of elements form a molecular compound?
The question is incomplete. No options are given (for which of the following) to answer the question.
What is the general name given to the compounds formed when elements burn in oxygen?
Oh honey, we're talking about oxides here. When elements get cozy with oxygen and start burning, they form these compounds called oxides. It's like a fiery love affair between elements and oxygen, leaving behind these sassy oxides as their legacy.
What is the name given to the energy required to separate one mole of the ions of an ionic compound?
The energy required to separate one mole of ions of an ionic compound is called the lattice energy. It is a measure of the strength of the ionic bonds within the compound.
Do relative proportions of elements in a given compound vary from sample to sample?
im not really sure....sorry
