Answer:
ion-dipole
Explanation:
Let us remember that the potassium cation is an ion, a positive ion to be precise.
There is a dipole existing in the hydrogen cyanide molecule. The positive end of the dipole is on hydrogen while the negative end of the dipole is on the cyanide moiety.
The only possible interaction between the potassium cation and the hydrogen cyanide is an ion dipole interaction. The cation interacts with the cyanide moiety having a partial negative charge in the molecule.
False
complete combustion produces carbon dioxide + water
Answer:
12
Explanation:
To get to this answer you have to look at the number first. So the given number is 12.47 and you need 2 sig figs.
To help you understand this more start off by underlining the first 2 numbers because 2 sig figs are needed. <u>12</u>.47
Now you want to look at the number after the underlined (I bolded that number). <u>12</u>.47
If the number is above 5 then you would round the previous number up by one but in this case it is 4 so you do not increase the number. Hence, you getting 12 as your final answer.
Hope this helped! Let me know if you have any questions.
1the carrier would be 3 as to the the yes and the no differ from 2 which would mean they are the same, but if you take three , you have more equal signal, giving it a better digital quality
2incorect, primary, and clocks-worth both as well also use binary ode, because they all have a timmid connetion between gavity waves
Answer: Exothermic because the ΔH is negative.
Explanation:
The standard enthalpy of formation or standard heat of formation of a compound is the change of enthalpy during the formation of 1 mole of the substance from its constituent elements, with all substances in their standard states.
Exothermic reactions are those reactions in which heat is released and 
is negative.Endothermic reactions are those reactions in which heat is absorbed and is positive.
The reaction is exothermic as the heat is released during the formation of 
as heat of formation of is negative.
