The false statement from the above is that: Temporary charge imbalances in the molecules lead to London dispersion forces.

<h3>What are the factors that affect London dispersion forces?</h3>

Generally, the factors which affects the London dispersion forces a dispersion force are as follows:

  • Shape of the molecules
  • Distance between molecules
  • Polarizability of the molecules

However, London dispersion forces simply refers to a sort of temporary attractive force formed when electrons in two adjacent atoms occupy positions that make the atoms form dipoles.

So therefore, temporary charge imbalances in the molecules lead to London dispersion forces is a false statement

You are performing a titration of a triprotic acid, when you spill water on your lab notebook. you can read that: pka 1 = 1.40,
eimsori [14]
According to the PH formula:
PH= Pka +㏒ [strong base/weak acid]
when we have PH at the first equivalence =3.35 and the Pka1 = 1.4
So, by substitution, we can get the value of ㏒[strong base / weak acid]
3.35 = 1.4 + ㏒[strong base/ weak acid]
∴㏒[strong base/weak acid] = 3.35-1.4 = 1.95 
to get the Pka2 we will substitute with the value of ㏒[strong base/ weak acid] and the value of PH of the second equivalence point
∴Pk2 = PH2 - ㏒[strong base/ weak acid]
          = 7.55 - 1.95 = 5.6

Radioactive decay with pennies
Ann [662]

Answer:

Explanation:

Have the class stand up. Tell them that they will be flipping the penny (you will tell them when); each time they flip one half life will have passed. If their penny lands on heads, they are radioactive and have decayed and they should sit; if their penny lands on tails, they have not decayed and may remain standing.

snow_tiger [21]

Answer:

The answer is "V = 18.8\  L".

Explanation:

Given:

n= 0.788 \ mmol = 0.788 \ mol \ \text{(1 mmol is a thousandths of a mol)}\\\\R = 0.08206\  \frac{Latm}{Kmol}\\\\T = 17.0^{\circ}\ C =  (17.0 + 273) \ K = 290 \ K\\\\ p=1\ atm\\\\V = ?

Using idel gas law:

PV = nRT\\\ \therefore \\\\V= \frac{nRT}{P}

V =\frac{0.788 \times 0.08206 \times  290}{1}

   =\frac{18.7523}{1} \\\\\ = 18.75

Which one of the following compounds is not covalent?
denpristay [2]
KCI is not a covalent compound, it is an ionic compound. 
A covalent compound is one in which each of the atoms involved contribute a specific number of electrons for sharing in order to from stable compound while an ionic compound is a compound formed when one atom donates electron to the other atom in the compound, in order to attain stability.  The compounds given in options A, B and D shared electrons while in KCl, potassium donates an electron to chlorine.
