2. The evaporation of water is created from thermal energy.

3. Cooking an egg uses thermal energy to cook.

2. The condensation of water from vapor in the air uses thermal energy.

Explanation:

1. Lighting a match uses chemical energy which is then converted into thermal energy.

2. Evaporating water can be cause by hot items like the Sun which plays the most important role in our water cycle by evaporating water.

3. Cooking an egg uses thermal energy because it take the heat away from the object used to cook with it.

Urgent!! A chemist measured 5.2 g copper(II) bromide tetrahydrate (CuBr2•4(H2O)). How many moles were measured out? Answer in un
bezimeni [28]
  The  moles  which  were   measured  out  is  calculated  using  the  following  formula

moles  =  mass/molar   mass

molar mass  of  CuBr2.4H20  =   63.5  Cu + (  2  x79.9)  br  + ( 18  x4_)  h20  =  295.3  g/mol

moles  is therefore=  5.2 g/  295.3 g/mol=  0.0176 moles
