Answer:
Three hydrogen atoms to form PH₃.
Explanation:
Hello!
In this case, since the elements belonging to the nitrogen family (N, P, As, Sb and Bi) show five valence electrons, because there are five electrons at their outer shell, it is clear that if phosphorous bonds with hydrogen, it is going to require the same amount of oxygen atoms (3) because elements having five valence electrons need 3 bonds in order to attain the octet (5+3=8).
Therefore the compound would be:
![PH_3](https://tex.z-dn.net/?f=PH_3)
Which is phosphine.
Best regards!
To convert 390 ml to grams, besides the volume we have to know the substance’s density ρ in g/cm3<span> or in any other unit. Alternatively, when we know the material, then we can look for its density in a search engine. As explained on our home page, 390 ml equal 390 cm</span>3<span>, and as also outlined there, in common use the equation for water is 390 milliliter = 390 g</span>
Answer:
The answer is true
Explanation:
Products in chemical reactions are rearranged during the reaction, the atoms end up in different combinations in the products. This makes the product new substances that are chemically different than the reactants
<span>CHCl3 because there are more than two atoms in this molecule that are different. Hydrogen has a small electron cloud and occupies less space, where Cl has a larger electron cloud and occupies more space, this would make it different than the expected tetrahedron shape.</span>
