The heat of solution for NaOH is -445.1kJ/mol. In an experiment, 5.00g of NaOH is completely dissolved in 1,000g of 20.0°C water in a foam cup calorimeter. Calculate
the final temperature of the water. (Cwater = 4.18 J/gx°C and NaOH is 40.0g/mol) plz show work

Which statement is true about ionic compounds?

What method(s) do plants use to obtain nitrogen? select all that apply. absorb it from the atmosphere use bacteria to convert nitrogen to usable form obtain usable nitrogen compounds from the soil absorb nitrogen from water taken in at the roots

For the reaction, 4 a(g) + 3 b(g) => 2 c(g), the following data were obtained at constant temperature. experiment initial[a],mol/l initial [b],mol/l initial rate, m/min 1 0.200 0.150 5.00 2 0.400 0.150 10.0 3 0.200 0.300 10.0 4 0.400 0.300 20.0 which of the following is the correct rate law for the reaction? 1. rate = k[a]2[b]2 2. rate = k[a][b] 3. rate = k[a]2[b] 4. rate = k[a][b]2
