What does a chemical formula tell you about a pure substance?
It tells you the elements and the proportions of those elements that are present to make the pure substance.
What is the change that a substance goes through to make another substance?
Chemical change
What are the six elements that make up substance?
The six elements that make up a substance are carbon, hydrogen, nitrogen, oxygen, phosphorus, and sulfur. These elements are commonly found in organic compounds and are essential for life.
What is called a change that does not make a substance into a new substance?
A change that does not make a substance into a new substance is called a physical change. In physical changes, the physical properties of the substance may change, such as shape, size, or state (solid, liquid, gas), but the chemical composition remains the same.
Does a physical change make the substance that undergoes it a different substance if not then what can change?
After a physical change a substance does not change its chemical composition it simply changes its state as, water to ice or vapours.
What happens to the atoms of the starting substance during a chemical reaction?
During a chemical reaction, the atoms of the starting substance rearrange to form new substances. The atoms themselves are not created or destroyed, but they may bond in new combinations resulting in different molecules.
How could you change a molecule of water and make it a completely different substance?
To change a molecule of water into a completely different substance, you would need to break the chemical bonds between the hydrogen and oxygen atoms in water (H2O) and then rearrange those atoms to form a new compound. For example, by introducing a reactive element such as sodium into the water molecule, you could create sodium hydroxide (NaOH), which is a completely different substance than water.
When two elements chemically bond to make a new substance with its own special properties the new substance?
When an affinity exist between these two elements, a difference in electronegativity.
How do you rearrange the letters of EIGHTH to make another word?
If you rearrange the letter of EIGHTH, you can make the word HEIGHT
Is combining hydrogen and oxygen to make water is a physical?
No.
Which substance will change the make of an egg?
hot water
What is a change that alters the form or appearance of a substance but does not make it into other substance?
It is considered a physical change. A chemical change involves chemical reactions that change the substance into another substance. A physical change typically only modifies the form or phase.
