A) how much has ph of pure water in equilibrium with the atmosphere changed between pre-industrial times and 2019? ( for information and co2 concentration now grows at 2.1 ppm/year)
b) predict your life expectancy and when you would take your last puff of atmospheric co2 based on typical life expectancy in the united states. calculate the expected pco2 by that time. what would the ph of pure water in equilibrium in the atmosphere by then?

What is the mass of sodium in 3 moles of sodium chloride

100 grams of molten lead (600°c) is used to make musket balls. if the lead shot is allowed to cool to room temperature (21°c), what is the change in entropy (in j/k) of the lead? (for the specific heat of molten and solid lead use 1.29 j/g⋅°c; the latent heat of fusion and the melting point of lead are 2.45 × 104 j/kg and 327°c, respectively.)

Vi limitens. vastery test select the correct answer. which statement explains why large atoms are more reactive than small atoms? a. large atoms have valence electrons farther from the nucleus and lose them more readily. b. large atoms have greater ionization energy, which they can utilize during a reaction. c. large atoms have a greater number of electrons that they can lose during a reaction. d. large atoms have more energy levels, so they have more energy to pass on in a reaction. reset next
