Worksheet: State Symbols

In this worksheet, we will practice using state symbols to denote whether reactants and products in a reaction are solids, liquids, gases, or solutes.

Q1:

In reaction equations, different notations are used to indicate different states of matter.

What is used to denote a solid?

  • A ( 𝑠 )
  • B ( 𝑎 𝑞 )
  • C ( 𝑔 )
  • D ( 𝑙 )

What is used to denote a liquid?

  • A ( 𝑎 𝑞 )
  • B ( 𝑔 )
  • C ( 𝑠 )
  • D ( 𝑙 )

What is used to denote a gas?

  • A ( 𝑙 )
  • B ( 𝑎 𝑞 )
  • C ( 𝑠 )
  • D ( 𝑔 )

What is used to denote a substance dissolved in water?

  • A ( 𝑠 )
  • B ( 𝑔 )
  • C ( 𝑙 )
  • D ( 𝑎 𝑞 )

Q2:

What is an aqueous solution?

  • APure water
  • BA 1 M solution
  • CA weak solution
  • DA solute, or solutes, dissolved in water
  • EWater dissolved in another solvent

Q3:

Oxyacetylene torches produce temperatures in excess of 3,000C. Under these conditions, acetylene burns completely according to the following equation: 2CH+5O4CO+2HO22222.

What state symbol can be applied to all the components of this reaction under these conditions?

  • A ( ) g
  • B ( ) a q
  • C ( ) s
  • D ( ) l
