It won't be possible for me to answer this question if there is no context. I tried to find a similar question and I came up with one. The problem is shown in the attached picture. From the given choices, all their units are atm*mL. So, that means that P*V. The answer could only be (2) or (4). Let's try the data in the table to find out.
PV = (0.5 atm)(1000 mL) = 500 atm*mL
PV = (1 atm)(500 mL) = 500 atm*mL
PV = (2 atm)(250 mL) = 500 atm*mL
<em />
<em>Thus, the answer is choice (2).</em>
Answer:
This answer I think it is Al,F
Answer:
Alpha decay is one type of radioactive decay, in which an atomic nucleus emits an alpha particle, and thereby transforms (or "decays") into an atom with a mass number decreased by 4 and atomic number decreased by 2.
Explanation:
The elements involved here are non-metals. The bond that forms between non-metals is a covalent bond where each atom shares one or more electron with the other so that both become stable. The number of shared electrons has to be equal for both.
Now, hydrogen needs only one electron to fill its outermost level and be stable and the same goes for fluorine, therefore, each of them shares one electron with the other.
Based on this, the answer would be:
<span>Hydrogen and fluorine share one electron with each other.</span>
Answer:
D. Sulfonation
Explanation:
Electrophilic aromatic substitution -
The subsitution reaction , where the hydrogen atom of an aromatic ring is replaced by an external electrophile .
Sulfonation reaction -
The subsitution reaction , where the hydrogen atom of an aromatic ring ( benzene) is replaced by an sulfonyl group , is called an Sulfonation reaction .
The Sulfonation reaction is reversible in nature , because , heating of aqueous sulfuric acid with sulfonic acid , can lead to a reverse reaction , i.e. , desulfonation .
