<h2>Answer:</h2><h3>Vitalism-</h3>
- A theory that an organic molecule cannot be produced from inorganic molecules, but instead can only be produced from a living organism or some part of a living organism. The theory was disproved in the early part of the 19th century<em>.</em>
<em>Translated</em><em>~</em>
- Teoría de que una molécula orgánica no se puede producir a partir de moléculas inorgánicas, sino que solo se puede producir a partir de un organismo vivo o de alguna parte de un organismo vivo. La teoría fue refutada a principios del siglo XIX.
The molarity is 3.50 M/L.
Explanation:
Molarity is found to know the amount of the solute ions present in the given volume of solution. So we determine it using the ratio of the moles of solute to the volume of the solution.
As here the weight of the solute which is hydrochloric acid is given as 17g, so we need to find the moles of it. This can be done by dividing the given amount of HCl with the molecular weight of HCl.
Molecular weight of HCl = 1.01 + 35.45 = 36.46 g/mol
So the number of moles of HCl present here will be
So, 0.466 moles of HCl is present in the solution.
Thus, the molarity is 3.50 M/L.

Answer:
e.iv, iii, i, ii
Explanation:
Be has electron configuration of 1s^2 2s^2. During bond formation, one 2s electron is promoted to a 2p orbital. Hence two hybrid sp beryllium orbitals are formed. These two hybrid orbitals are used in sigma bond formation to fluorine atoms.
Recall that fluorine has filled 2p orbitals containing lone pairs of electrons. These filled orbitals can interact with the unhybridized 2p-orbitals on beryllium to form pi bonds. This is the reason for the sequence of events chosen in the answer.
Electron cloud is the region around the nucleus in an atom where we can locate an electron.
The concept of electron cloud model was introduced by the Schrodinger and Heisenberg. According to this model, it would be difficult to know the position of the electrons in an atom and they are not particles that orbit around the nucleus. We can only expect the electrons to be present in specific areas called the electron clouds around the nucleus. It is the quantum mechanical model that used the concept of electron clouds. According to the model, the electron cloud or an orbital is a space around the nucleus in an atom where the probability of finding an electron is 90%. It explains that electrons show wave nature. It is difficult to determine the exact position and momentum of an electron in an atom.
