Information would you need to know about the H₂O₂ solution is through stoichiometry experiment
The ideal gas constant R can be found experimentally by determining the number of moles of gas that occupies a particular measured volume at a known pressure and temprature and the H₂O₂ is a chemical compound used un various chemical reactions and is slightly viscous than water and the experiment by decomposition of hydrogen peroxide and using the ideal gas law rearrangement equation we can calculate the value of r and we will need the information such as concentration, volume and moles of H₂O₂ to determine its stoichiometry

<span>Carbon (C) is most likely to form covalent bonds with Beryllium (Be) or Sodium (Na) because they are both metals and covalent bonds are metals that share their valence electrons with the gases / non-metals to get to the stable octet. Krypton is a gas and Selenium is a metalloid</span>
A chemical bond is created by either the transfer or sharing of electrons. Electrons with a missing full outer shell will be the ones participating in the bonding process. Hope this helped :)
<span>The 80 ml solution has (.04)(80) ml of the medicine, or 3.3 ml of medicine.The pharmacist adds V ml of 7% solution, or .07V ml of medicine. The total amoune of medicine is (.07V + 3.2) mg.
The total volume of solution is (V + 80) ml, so
(.07V + 3.2) / (V + 80) = .05. Solve for V.</span>
