<span>100 g of KClO3 @ 122.55 g/mol = 0.816 moles of KClO3
by the reaction
2 KClO3 --> 2 KCl & 3 O2
0.816 moles of KClO3 @ 3 moles O2 / 2 moles KClO3 = 1.224 moles of O2 can be made
using molar mass
1.224 moles of O2 @ 32.0 g/mol =
39.2 grams of O2 can be made</span>
Penicillin V is an antibiotic in the penicillin group of drugs. It fights bacteria in your body. Penicillin V is used to treat many different types of infections caused by bacteria, such as ear infections,. Penicillin V may also be used for other purposes not listed in this medication guide.
Ionic compounds have very high melting and boiling point. This property tells us that the particles are bonded together by strong electrostatic forces of attraction. It is because of this very strong electrostatic forces that gives the compound high melting and boiling point.
Answer:
Iron (Fe)
Explanation:
The number of electrons (-) is usually the same as the number of protons (+) in the atom of the element (unless it is an ion).
The element described has 26 electrons, so we can assume that it has 26 protons as well. The number of protons in an atom is the atomic number of element that the atom is.
Element 26 on the PTE is Iron (Fe), which does rust (oxidation) in air and water.
