A chemistry student is setting up a single-replacement reaction between 5 grams of solid zinc metal and
aqueous hydrochloric acid, as shown in the equation
below:
Zn (0) + 2 HCl(aq) >ZnCl2 (aq)
>ZnCl2 (aq) + H2(g)
She needs to finish the experiment before the end of
lunch, so she wants the reaction to go as quickly as
possible. She has several types of zinc in the stock
room. Which type should she use?
o one solid 5 g cube of zinc
o It doesn't matter; they will all react at the same rate.
o 5g of small chunks of zinc
O5g of fine zinc powder

3 hours because it is a decent distance.

intermolecular forces are the forces between molecules or particles.

there are two kinds of van der waals forces: weak london dispersion forces and stronger dipole-dipole forces.

in molecule of water there are dipole-dipole forces between negatively charged oxygen from one molecule of water and positively charger hydrogen of another molecule of water.

hydrogen bond is an electrostatic attraction between two polar groups that occurs when a hydrogen atom (h), covalently bound to a highly electronegative atom such as flourine (f), oxygen (o) and nitrogen (n) atoms.
