Step 1. Solve for the energy needed to heat 18 g of water from 70°C to 100 °C
(boiling point). Use specific heat of water
(4.2 J/g °C) as conversion factor.
18 g x (100-70) °C x 4.2 J/g °C =?

Which statement is true regarding the diagram of circle p? the sum of y and z must be 2x. the sum of y and z must be x. the difference of z and y must be 2x. the difference of z and y must be x

Water is called the universal solvent because more substances dissolve in water than in any other chemical. this has to do with the polarity of each water molecule. the hydrogen side of each water (h2o) molecule carries a slight positive electric charge, while the oxygen side carries a slight negative electric charge.

What is the pressure of 5.0 mol nitrogen gas in a 2.0 l container at 268 k (the universal gas constant is 0.0821 l•atm/mol•k) a. 55 atm b. 8.8 atm c. 0.018 atm d. 220 atm
