To convert a value from one unit to another, we need a conversion factor to multiply with the value. For this case, we know that for 1hm it is equal to 100 m and that 1 m^3 is equal to 1000 L. We use these:
25 L (1 m^3 / 1000 L ) ( 1 hm / 100 m )^3 = 2.5x10^-8 hm^3
Therefore, the correct answer should be the first option. The statement "<span>fraction cubed: one m over ten to the negative second power m</span>" is not a correct factor.
There are two molecular orbitals in the CH2O or formaldehyde. These are designated by the two types of bonding involved. The first is the sigma bonding. It is the head-on overlap of electrons of the C and H atoms. The second molecular orbital is formed from the pi orbital bonding. This is a sideway overlap of electrons between C-O bonding.
Nitric acid is HNO3 while Calcium Hydroxide is a base with a chemical formula Ca(OH)2. When acid reacts with base, it forms salt and water (H20). Hence forming the equation HNO3 + Ca(OH)2 -> Ca(NO3)2 + H20.
To gain the same number of atoms on both sides, the balanced molecular equation should be:
2NO3 + Ca(OH)2 -> Ca(NO3)2 + 2H2O
with: 4 Hydrogen, 2 Nitrogen, 8 Oxygen, and 1 Calcium
