Alex heated water in a pan until the entire water changed in to vapor. the mass of the total vapor formed was 150g. what was most likely the mass of the water alex headted and why? 175 g, water vapor formed is lighter then water 150 g, mass of the water remains the same when it changes state 175 g, some water molecules are destroyed during phase change 150 g, mass remains same during chemical change of water into vapor

B) 150 g, mass of the water remains the same when it changes state

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.
