A student investigated the rate of the reaction between zinc and sulfuric acid. Hydrogen gas is produced during this reaction. This is the method used. 1. Add 50 cm3 of sulfuric acid to a conical flask. 2. Add 2.0 g of zinc to the conical flask. 3. Quickly put a stopper in the conical flask and start a timer. 4. Measure the time taken to collect 20 cm3 of gas. 5. Repeat steps 1 to 4 three more times. Suggest why the stopper must be put in the conical flask as quickly as possible in step ...

The speed of a wave (c) is the product of its frequency (ν) and wavelength (λ). E = hv = h x c / λ nm to m or m to nm 1 m / 10^9 nm or 10^9 nm / 1 m What is the maximum number of electrons that can have the quantum numbers n = 3, ℓ = 2, mℓ = -2? The Pauli exclusion principle states that no two electrons in a given atom can share the same set of four quantum numbers (n, ℓ, mℓ, ms). This set of quantum numbers contains three quantum numbers, with the only missing quantum num...
