a period 2 nonmetal, X, forms the molecular compound NX3. Which of the following are also correct formulas for molecular compounds involving X?
HX
OX2
C2X
pleas explain why
thank you so much
Well, well, well, let's break it down with a little clown humor, shall we?
First up, we have HX. Now, hydrogen (H) is a period 1 nonmetal and it likes to bond with its buddy nonmetal, so HX could definitely be a molecular compound. Nice try!
Now, moving on to OX2. Oxygen (O) is a period 2 nonmetal, just like our mysterious element X. But does oxygen like to bond with itself to form OX2? Nah! Oxygen usually prefers forming its magical double bonds, like in good old O2. So, OX2 isn't a very likely formula. Better luck next time!
Lastly, we have C2X. Ah, carbon (C), a versatile element that can bond with all sorts of things. But can it form a molecular compound with our friend X? Well, since X is a period 2 nonmetal, it's possible that it could bond with carbon. So, C2X could indeed be a correct formula! Hooray!
To summarize, the correct formulas for molecular compounds involving the period 2 nonmetal X are HX and C2X. OX2 isn't quite the right fit because oxygen prefers its magical double bonds. So, keep your clown nose on straight and remember, it's all about the bonds, baby!
To determine the correct formulas for molecular compounds involving the nonmetal X, we need to understand the valency of X and the rules for combining elements.
1. HX: This formula is a valid option because hydrogen (H) is a nonmetal and typically forms compounds with other nonmetals. Since X is a period 2 nonmetal, it is likely to form a compound with hydrogen.
2. OX2: This formula is not likely to be correct. Oxygen (O) is a period 2 nonmetal, and based on the given information, X is the nonmetal forming the compound NX3. Therefore, it is unlikely that X would also form a compound with oxygen.
3. C2X: This formula is not likely to be correct. Carbon (C) is not a nonmetal in period 2, meaning it does not fall under the given conditions for X. Therefore, it is unlikely that carbon would form a compound with X.
In summary, the correct formulas for molecular compounds involving X, based on the given information, are HX.
To determine which of the given formulas (HX, OX2, C2X) are correct for molecular compounds involving the given nonmetal X, we should understand the general rules for naming and formula writing in chemistry.
The fact that X is a period 2 nonmetal means that it belongs to a group in the periodic table that contains elements like oxygen (O), nitrogen (N), and fluorine (F). These elements typically form covalent bonds and share electrons to achieve stable electron configurations.
Now, let's go through each option:
1. HX: This formula represents a compound where one atom of hydrogen (H) combines with one atom of X. This is a valid formula for a molecular compound involving X because X can typically form a single bond with hydrogen.
2. OX2: This formula represents a compound where one atom of oxygen (O) combines with two atoms of X. However, the problem states that X forms the molecular compound NX3, which implies three atoms of X. So, the formula OX2 is not valid.
3. C2X: This formula represents a compound where two atoms of carbon (C) combine with one atom of X. The problem does not indicate the involvement of carbon in the molecular compound, so the formula C2X is not valid in this context.
Therefore, the correct formula for a molecular compound involving X is HX.
In summary:
- HX is a correct formula because X can bond with hydrogen.
- OX2 is not a correct formula because the problem specifies NX3, not OX2.
- C2X is not a correct formula because the problem does not mention carbon.
I hope this clarifies the answer to your question! Let me know if you need further assistance.
In NX3 the N would be +3 and the X would be +1 or -1.
This means that it would have to be HX and OX2 because it would have H+ and X-
and O2-X-
I'm not sure how you were taught but I was taught to cross the the charges.
