Elements are like loners, compounds are like couples, and mixtures are like a group of friends that can also have couples (compounds)
Answer:
i know the problem
2c2h6(g)+702(g)->4co2(G)+6g20(1) thats double replacement i dont know the first part
Body temperature is the main one. blood ph is very important. and reflex reactions. if this was right please give me brainliest
In chemistry, a precipitation reaction is a double replacement reaction. It involves two reactants and two products. It means that the cations and anions of the compounds interchange with one another to yield two products. But what makes precipitation reactions different is that when two liquid reactants are allowed to react together, a solid substance called precipitate is formed. The solid appears because it is insoluble to the other product in aqueous state.
Therefore, basing on the choices given, precipitation reactions apply to letters C and D.
Explanation:
i think
Each ion, or atom, has a particular mass; similarly, each mole of a given pure substance also has a definite mass. The mass of one mole of atoms of a pure element in grams is equivalent to the atomic mass of that element in atomic mass units (amu) or in grams per mole (g/mol).
