  Have you got routes set on the two routers so they know how to reach the networks that each other have connected?
  
  So on Router 1 you need the following static route:
  ip route 172.16.0.0 255.255.0.0 192.168.1.2
  
  And on router 2 you need the following:
  ip route 192.168.10.0/24 192.168.1.1
  ip route 10.0.0.0 255.0.0.0 192.168.1.1
  
  Hope that helps

  As above. The routers will know about the networks that they are directly attached to, hence why router 1 can route between PC1's network and PC2's network. But router 2 only knows about the network of PC3 and the serial link.
  
  So you either need to set up static routing (ie tell the router, if you want to reach these networks, send the traffic this way), or use a routing protocol (basically so the routers can talk to each other and say "yeah, I have access to these networks and if you want to reach them, just send the traffic my way.")
  
  The other thing to remember with pings, is that you need to path to the destination (to send the ping request), and also the path back (to receive the reply) - so router 1 needs to know how to get to router 3's networks AND router 3 needs to know how to get to router 1's networks.

  Here's a neat video that explains networking basics at an IP/ARP level and why routers are needed between networks, etc. This could help further your understanding on a fun level.
  
  Enjoy!
