Part A Predict the boiling point of a mixture made up of 0.70 mole fraction of A and 0.30 mole fraction of B Express your answer as an integer and include the appropriate units. The boiling point of a mixture of two volatile liquids depends on how much of each component is present. This graph shows the boiling temperature versus mole fraction composition. (Figure 1) Fractional...

Determine whether each statement describes the solid state, liquid state, or gaseous state. Answer Bank gas This state is characterized by the lowest density of the three states. solid liquid liquid This state is characterized by an indefinite shape and high density. solid Temperature changes significantly influence the volume of this state. gas Pressure changes influence the volume of this state more than the other two states. solid In this state, constituent particles are less free to move around than...

the correct answer is 15 , how to get it ..
Determine how many terms of the following convergent series must be summed to be sure that the remainder is less than 10-4 Σ (-1k (7k+ 1)2 k=0 The number of terms that must be summed is 15' (Round up to the nearest integer as needed.)

Suppose you were to determine the density of a solid and gas-how will the procedures and results differ from that of a liquid?Note: a good answer will address procedure differences between all three states of matter and will compare density results for all three states of matter.
