Be sure to answer all parts. Express the rate of reaction in terms of the change in concentration of each of the reactants and products: 2D(g) + 3E(g) + F(g) → 2G(g) + H(g) Rate = 1 2 Δ[D] Δt = 1 3 Δ[E] Δt = 2 3 Δ[F] Δt = − 1 2 Δ[G] Δt = − Δ[H] Δt Rate = − 2 Δ[D] Δt = − 3 Δ[E] Δt = − Δ[F] Δt = 2 Δ[G] Δt = Δ[H] Δt Rate = − 1 2 Δ[D] Δt = − 1 3 Δ[E] Δt = − Δ[F] Δt = 1 2 Δ[G] Δt = Δ[H] Δt When [D] is decreasing at 0.94 mol/L·s, how fast is [H] increasing? mol/L·s

you need to take a look at the periodic system in order to sort these elements into pairs that would most likely exhibit similar chemical properties. first, you need to find elements that are found in the same group (groups are vertical in the periodic system), and then to see whether they have the same valence number. if they meet these criteria, they will have similar properties.

the first pair: ne (neon) and kr (krypton), are noble gases found in group 8

the second pair: li (lithium) and k (potassium), found in group 1

the third pair: s (sulfur) and te (tellurium), found in group 6

in scientific notation, the value of the  speed of light in a vacuum

  will be written as 2.995 * 10^8. when this value is represented in the form of

  a * 10^b, then, a = 2.995 and b = 8.

the value of the speed of light in a vacuum given above can also be rounded up to approximately 300000000. in this case, the scientific notation will be written as 3 *10^8.
