WILL GIVE BRAINIEST PLS HELP RN : In the backyard calorimetry lab I had 189.5 grams of water in my Batman thermos. The water started out at a
temperature of 16.4 °C. After a few minutes the water cooled to 8.9°C. How much thermal energy did the
water use to melt the ice cube?

Hey can you me with this i really need y’all

Count the number of each type of atom in the equation below, and then balance the equation. write in the numbers of atoms and coefficients. add a 1 if there should be no coefficient. cs2(l) + o2(g) → co2(g) + so2(g) c [ ] s [ ] o > c [ ] s [ ] o [ ] cs2(l) + [ ] o2(g) > [ ] co2(g) + [ ] so2(g)

Nitrogen dioxide decomposes according to the reaction 2 no2(g) ⇌ 2 no(g) + o2(g) where kp = 4.48 × 10−13 at a certain temperature. if 0.70 atm of no2 is added to a container and allowed to come to equilibrium, what are the equilibrium partial pressures of no(g) and o2(g)
