Elements withing a burning star combine until the core becomes iron, which is too dense to combine into anything else. Depending on the size of the star, how many solar masses it is, it will either cool off or, if it's big enough then it turns into a black hole, due to the massive gravitational pull it has within its core.

A chemical change combining two elements result in?

Is fettuccine alfredo a chemical change?
No, the making of alfredo sauce is simply the combining of elements/ingredients. No chemical change occurs.
Explain why it is futile to try to create gold by combining other elements?
It is futile to create gold by combining other elements because gold is a unique element with a specific number of protons in its nucleus (atomic number 79). Changing the number of protons would change the element entirely, making it impossible to create gold by combining different elements. The process of transmuting elements to create gold would require immense energy and is not feasible with current technology.
What is a combining form not a prefix or suffix?
A combining form is a word part that can stand alone when combined with other word elements to create a new word. It is not a prefix or suffix because it does not change the meaning of the original combining form, but rather enhances or specifies it.
Is a stack of wood on a fire a chemical or physical change?
Chemical. When wood is heated, oxygen begins rapidly combining with the wood and the by-product of this is heat and smoke. What's left over is mostly carbon, the rest having been converted into energy by combining with oxygen.
How does the mass of the lements that form inside of a star change based on the stage in its life cycle the star occupies?
During the main sequence stage, a star's core fuses hydrogen into helium, converting mass into energy. As the star evolves into later stages, it begins fusing heavier elements and creating new elements. This process changes the elemental composition of the star's core, ultimately influencing its mass.
One element can change to another by the process of?
Transmutation is the process by which one element changes into another. This can only be done with a nuclear reaction, but alchemists once believed it might be possible, for example, to transmute lead into gold. They tried many bizarre things, but were never successful. Only nuclear reactions, such as fusion, fission, radioactive decay, etc, can induce a transmutation.
Is combining hydrogen and oxygen a physical change or a chemical change?
This is a chemical change.
What word begins with a and means to change or vary?
Alternate is a synonym for change or vary. It begins with the letter a.
Do elements easily change into new elements?
No. It is quite difficult for elements to change into new elements.
Is a star a pure substance?
No - a star would not be a pure substance. Our understanding of how stars function includes a continuous fusion of hydrogen to form helium and, depending on the star, possibly further fusion of the helium into even heavier elements. Once formed, these heavier elements do not just go away or change back into helium so stars will always be composed of a mixture of hydrogen and the byproducts of fusion.
Is Oxygen and hydrogen combining to form water a physical or chemical change?
The formation of water from oxygen and hydrogen is a chemical change because new chemical bonds are formed between the atoms to create a new substance with different properties than the original elements.
