A 1500.0 L sample of water vapor condenses to form 0.850 L of liquid while releasing 2150 kJ of heat. What are the signs of q and w for this exothermic process

To save time, you can approximate the initial mass of the solid to the nearest ±1 g. for example, if you are asked to add 14.3 g of copper, add between 13 g and 15 g. which of the following sets include two samples with an equal density? which all that apply below 15.4 g gold and 18.7 g silver 15.2 g copper and 50.0 g copper 20.2 g silver and 20.2 g copper 11.2 g gold and 14.9 g gold

Which element would mostly likely have an electron affinity measuring closest to zero

May someone me with these science questions
