Answer:
8
Step-by-step explanation:
I hope this helps you out!
A double replacement reaction occurs when the ionic parts of two ionic compounds are exchanged.
Reaction 1 results in a product which is a single compound. No ionic parts are exchanged.
Reaction 3 results in one compound being separated into its elemental parts. No ionic parts are exchanged.
Reaction 4 has two reactants, but Pb is an element and not an ionic compound. No ionic parts are exchanged.
Hence, the answer is Reaction 2. Both NaBr and Ca(OH)2 are ionic compounds. Br - is the anion in NaBr, and (OH)2 is also an anion. Ionic parts are exchanged.

This time its thousands not hundreds, so you do 17 plus 000 wich would be thousands, like this
one thousand

Answer:
/2
Step-by-step explanation:
/
=1.2422
/2=0.66 <-- not matching with the top expression.
/2=1.11<--not matching with the top expression.
/2=1.2422<-- matches!!
/3=0.91<-- not matching with the top expression.
Answer:
(22) = 7
Step-by-step explanation:
The inverse function maps the output of the function back to its input
f(7) = 22 means when input is 7 the output is 22
The inverse maps the output 22 back to the input 7 , that is
(22) = 7
