To solve this we assume
that the gas is an ideal gas. Then, we can use the
ideal gas equation which is expressed as PV = nRT. At a constant volume and
number of moles of the gas the ratio of T and P is equal to some constant.
At another set of condition, the constant is still the same. Calculations are
as follows:
T1/P1 = T2/P2
P2 = T2 x P1 / T1
P2 = 450 (750) / 300
<span>P2 = 1125 torr</span>
I assume you are looking at amino acids/proteins.
The N-terminus is the amino group (nitrogen) of the amino acid
<span>23.8 g/mol
Since the definition of molar mass is mass per mole, just divide the mass of the sample by the number of moles you have. So
0.250 g / 1.05x10^-2 mol = 23.8095 g/mol
Since our input data only has 3 significant figures, you need to round the result to 3 significant figures.
23.8095 g/mol rounds to 23.8 g/mol</span>
Answer:
[Ne] 3s² 3d³
Explanation:
According to aufbau's principle of filling electronic orbitals, the sublevels with lower energies are filled up before those with higher energies.
One important to know about this principle is that sublevels do not fill in numerical order.
The order of filling is;
1s 2s 2p 3s 3p 4s 3d 4p 5s 4d 5p 6s 4f 5d 6p 7s 5f e.tc
From the given choices the wrong one is;
[Ne] 3s² 3d³
3p fills up before 3d;
