Connect the Molecules

An old early iOS game where you were presented with puzzles that involved a 'grid' of 'molecules', and were tasked to create certain, and or certain amounts of 'chemicals'. Each level is a different layout comprised of 'molecules' and 'walls', some walls being destructible. There are many different types of molecules, such as hydrogen and oxygen, which join to make water, or unstable molecules that would explode and destroy walls. You swiped to move molecules, which would not stop until it collided with a wall or molecule.
