Thank you for posting your question here at brainly. I hope the answer will help you. Feel free to ask more questions.
density 15.4 grams per 1.2³ cm³ ≅ 8.9 grams per cm³
<span>Find the metal that has a density of approximately 8.9 g/cm³</span>
They have a full valence shell (8 electrons in the outer shell) so they are the most stable elements on the periodic table. Therefore, they do not need to react to other elements to gain or lose elections to become stable.
C + O2= CO2
CO2 is limit
5.4-3.72= 1.68 g of C is excess
5.4 g = 100%
3.72 g = x
x=68.9 %
It depends on the pH level of the water.
I think the correct answer from the choices listed above is option C. Chemical reaction is the process <span>that changes one set of chemicals into another set of chemicals. In a chemical reaction, old bonds are broken down forming new bonds therefore new </span>substances<span> with new properties.</span>
