is first order in N₂O₅. For this reaction at 45°C, the rate constant k = 1.0 x 10⁻⁵ s⁻¹, where the rate law is defined as
Rate =
For a particular experiment ([N₂O₅]₀ = 1.0 x 10⁻³ M), calculate [N₂O₅] after 3.5 x 10⁵ seconds.

the leaf is an organ of a typical plant, and the main functions are to complete photosynthesis and allow the plant to exchange gas, just like how we have the respiratory system. leaves have the stomata, which collects maintains co2 and o2 levels. this is necessary for cell metabolism. the leaf also collects sunlight using chloroplasts. succinctly, leaves own a pivotal role in sustaining plant life.

b. accuracy of the data matters alot more than its number of digits, organization or amount of detail. quantitative observation is more accepted than the qualitative observation.

it is reliable if two scientists recorded it
