Answer:
Equation 2, because K being more reactive, exchanges position with Pb in PbNO3.
Explanation:
Hello there!
In this case, according to the given reactions, it is possible to realize that according to the reactivity series, since K is is group 1A of alkali metals, we infer it is by far more reactive than magnesium, for that reason last two choices can be easily discarded. Now, considering equation 2, it would be necessary to complete it to figure out the correct option:
Whereas it can be seen that potassium exchanges position with Pb according to the double displacement reaction; therefore, the correct answer is "Equation 2, because K being more reactive, exchanges position with Pb in PbNO3".
Best regards!
Answer:
False
Explanation:
This equal distribution of electrons means that the molecule has no separate positive and negative areas (nonpolar). It has polar and nonpolar properties; has an ionic end that will dissolve in water and a long hydrocarbon portion that will dissolve in oily dirt.
Answer:
142.0 moles CO₂
Explanation:
To answer this question, we first need to know what a mole is. A mole represents of something, and in this case, that something is molecules.
So, to convert molecules into moles, we need to use the conversion factor .
Doing so (using dimensional analysis) gives us:
Answer:
Carbon tends to bond covalently with Hydrogen
