Which solution would be considered a
weak base ?

This is an ionic compound of Ca2+ ions and OH− ions. When an ionic compound dissolves, it separates into its constituent ions:

Ca(OH)2→Ca2+(aq)+2OH−(aq)

Because Ca(OH)2 is listed in Table  14.7.1 , this reaction proceeds 100% to products so the answer is B.

Explanation: your welcome P.S I am a D.J and im listening to marshmello's Alone music in my room ;)

the transfer for conduction is the heat transfering from the liquid to the spoon

the transfer for convection is the heat rising from the liquid to the air

the transfer for radiation is the heat going through the sides of the cup and to the air

at least that is what i would do

but there is no

i guess you forgot putting it.
