The solution is basic since it has a pH of 11.6. A pH
Answer:
Nonmetals are located on the upper right side of the Periodic table (see above image). Exception: Hydrogen is a nonmetal which is located on the left top corner of the Periodic table. Well, you have got the answer of “Where are Nonmetals located on the Periodic Table?”
Explanation:
This means that neutral zinc atom has a total of 30 electrons surrounding its nucleus. To see how many of these electrons are valence electrons, write the electron configuration of a neutral zinc atom. Notice that the outermost shell, which for zinc is the fourth shell, n=4, has two electrons. Hope this helps. :)
Answer:
Temperature, pressure, shape of container
When the concentration is expressed in mass percentage, that means there is 3 g of solvent H₂O₂ in 100 grams of the solution. Then, that means the remaining amount of solute is 97 g. We use the value of molarity (moles/liters) to determine the amount of solution in liters, denoted as V. The solution is as follows:
0.02 mol KMnO4/L solution * 158.034 g KMnO4/mol * V = 97 g KMnO4
Solving for V,
V = 30.69 L
