The number of orbitals that are completely full is 5.
The reason you may have thought it was 3 is because you're confusing orbitals with subshells.
In this electron configuration, the sub shells are: 1s^2, 2s^2, 2p^6, 3s^1
So, we have four sub shells.
Each sub shell consists of a specific number of orbitals. s subshells have one orbital, p subshells have three orbitals, d subshells have five orbitals, and f subshells have seven orbitals. Knowing this, we can look back at the electron configuration we were given and determine how many orbitals are filled.
1s^2 has one orbital, 2s^2 has one orbital, 2p^6 has three orbitals, and 3s^1 has one orbital. The first three subshells are completely full, so a total of five orbitals are full.

Answer:
The presence of nitrogen in the organic compound is detected by fusing organic compounds with sodium metal to give sodium cyanide (NaCN) soluble in water. This is converted into sodium ferrocyanide by the addition of sufficient quantities of ferrous sulphate.
Explanation:
It is what I found online.
Answer:
Quantitative experiments show that 4.18 Joules of heat energy are required to raise the temperature of 1g of water by 1°C. Thus, a liter (1000g) of water that increased from 24 to 25°C has absorbed 4.18 J/g°C x 1000g x 1°C or 4180 Joules of energy.
solution:
First we calculate the number of mole of gas as follows:
PV = n RT
Here temperature; T= 100°C or 373 K
n = PV/ RT
= 4.78 atm * 3.82 L / 0.0821 L ∙ atm / mol ∙ K * 373 K
= 0.596 Moles
Now determine the molar mass of gas as follows:
Number of moles = amount in g/ molar mass
Molar mass = 19.08 grams / 0.596 Moles
= 32.013 g/ mole
This the molar mass of O2 hence the gas is oxygen
