Abeaker contains 450 g of water if 9.2g of calcium fluoride is added what is the molality concentration of the solution

Water molecules have a strong attraction to each other because of hydrogen bonding, allowing water to move against gravity up a plant's stem through capillary action. true false

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

Light waves can move through , but they travel fastest when they move through a(n) .
