12 moles are in the 175L of SO2 gas at STP
Answer:
Nocturnal animals, such as owls, tend to have wide pupils and several rod cells in their retina because wide pupil allow more light to enter the eyes and the rods cells in the retina are sensitive to dim light and are vital for night vision.
First compute the number of grams of manganese metal required to make 21.7 grams of H2.
21.7 g H2 x (1 mole H2/ 2 g H2) x (1 mole Mn/1 mol H2) x (55 grams Mn/1 mol Mn) = 596.75 grams
Now density = mass/volume
7.43 = 596.75/volume
volume = 596.75/7.43 = 80.31 mL
80.31 mL is the amount of manganese needed.
Answer:
Explanation:
The symbol of beryllium is Be. It is located in the second group on the periodic table.
Beryllium is a divalent cation with a charge of +2.
It is capable of losing 2 electrons in order to be like the noble gas He and this is a more stable configuration.
Answer:
HOCl is the preferred arrangement.
Explanation:
Hypochlorous acid (HOCl or HClO) is a weak acid that contains Hydrogen, Chlorine and oxygen. Generally both are accurate molecular formulars as hey show the exact number of atoms of elements present in the compound.
However the preferred formular is HOCl. The reason for this is because HOCl implies the molecular structure (that is, how the atoms are bonded to each other). The H is bonded to the O and the O in turn is being bonded to the Cl. HClO on the other hand says nothing about the molecular structure.
