i dont know thats why i asked you
Thats sugar+oxygen Arent all chemical changes physical?
It is Iron III hydroxide (thats the brick red precipitate). It forms as well sodium chloride which is soluble in the water of the reaction and therefore you do not see.
whan a sperm cell enter the egg cell and make a baby thats the huge chemical reaction
Thats what i was wondering
When iodine and iron react, they form iron (III) iodide. This chemical reaction is a synthesis reaction, where the two elements combine to form a compound. Iron (III) iodide is a black solid compound that is soluble in water.
your mom thats what
Theoretically, chemical equations are reversible but in reality this is not true. Combustion is not normally written as a reversible reaction unless in an extreme hypothetical sense. Generally, one cannot tell if a chemical equation is reversible. It is a matter of experience and study.
When atoms have a chemical reaction, that usually means that they changed their state and can not go back. For example, if you put food coloring in a glass of water, thats a chemical reaction because it cannot go back to its original form of just water. Or if you change a liquid into a solid or a solid into a gas and so on. Those would all be chemical reactions. We just learned about that a few weeks ago.
ice thats formed in clouds.
When vinegar (acetic acid) is added to bicarbonate of soda (sodium bicarbonate), a chemical reaction occurs that produces carbon dioxide gas, water, and sodium acetate. The formation of new substances with different properties is characteristic of a chemical change.
i no thats waat i m sking
