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.
Answer : The correct option is, (B) 273.15 K and 1 atm
Explanation :
STP : STP stands for standard temperature and pressure.
STP conditions :
The temperature is, 
or 
or 
The pressure is, 
or 
The volume is 22.4 L for 1 mole of a substance.
Hence, the correct option is, (B) 273.15 K and 1 atm
Answer:
Gay-Lussac's Law
Explanation:
The pressure is directly proportional to the absolute temperature under constant volume. This states the Gay-Lussac's law. The equation is:
P1T2 = P2T1
<em>Where P is pressure and T absolute temperature of 1, initial state and 2, final state of the gas.</em>

That means the right option is:
- Gay-Lussac's Law
I think the anwer is electrolyte :)... i had it on a test a couple days ago.
