Question

match each material to where it is used in smartphones. get help here silicon graphite lithium tantalum batteries circuit board circuit board batteries

Explanation:

• Silicon is a key material in semiconductor manufacturing, and microchips (on circuit boards) in smartphones use silicon - so silicon matches with circuit board.
• Graphite is used in the anodes of lithium - ion batteries in smartphones, so graphite matches with batteries.
• Lithium is a crucial component of lithium - ion batteries (used in smartphone batteries), so lithium matches with batteries.
• Tantalum is used in capacitors on circuit boards of smartphones, so tantalum matches with circuit board.

Answer:

• silicon - circuit board
• graphite - batteries
• lithium - batteries
• tantalum - circuit board
