I can confirm that's the correct answer
Answer:
In fluorine, the electrons are tightly held to the nuclei. The electrons have little chance to wander to one side of the molecule, so the London dispersion forces are relatively weak. At a low enough temperature the molecules will all be solids. At a high enough temperature they will all be gases.
Answer:
Explanation:E=hc¯ν=hcλ [Where h = Planck's constant, c = velocity of electromagnetic radiation(light) and lambda = wavelength.] So, just substitute every needed value. =1.29077⋅10−18 Joules
Answer:
HBr + Mg(OH)2 —> MgBr2 + H2O.
To balance the above, we must do a head count of the individual atoms present to ensure they balance on both sides of the equation. To get the balance equation, add 2 in front of HBr and 2 in front of H2O as shown below:
2HBr + Mg(OH)2 —> MgBr2 + 2H2O
We can see clearly that the numbers of the individual atoms on the left side is the same on the right side
Answer:
number 3 is balanced
Explanation:
left side equal right side
