<span>I would figure this out slowly. So the percentage would be 25 2.6 billion years ago. That would leave it at 50 percent 5.2 billion years ago. If you double that 50 percent to get 100% and double the 5.2 billion years you get 10.4 billion years. This would make the answer, the rock is 10.4 billion years old</span>
Answer:
See explanation.
Explanation:
Hello,
In this case, we can realize that water has a very simple atomic structure which consists of two hydrogen atoms bonded to one oxygen atom. The nature of the atomic structure of water causes its molecules to have unique electrochemical properties. The hydrogen side of the water molecule has a slight positive charge whereas at the other side of the molecule a negative charge exists. This molecular polarity causes water to be a powerful solvent and is responsible for its strong surface tension.
Moreover, water is involved in several both inorganic and organic chemical reactions leading to hydration, for example, the conversion of alkenes to alcohols, the hydrolysis of acyl halides, anhydrides, esters and amides to carboxylic acids and the hydration of a raft of inorganic salts that exist as hydrates only, such as copper (II) sulfate pentahydrate and so.
Best regards.

Explanation: you have not cooked them so nothing has happened
Answer:
The answer to your question is below
Explanation:
Law of conservation of mass:
mass of reactants = mass of products
Problem
mass of beakers before mixing = mass of beakers after mixing
Beaker A (128.71) + Beaker B (128.97) = Beaker A (154.1) + Beaker B (103.58)
257.68 g = 257.68 g
Then the law of conservation of mass is true
