Suppose that a different student obtained reaction rates for the particle-size experiment, and that these rates did not show a pattern. Check all possible sources of this error. Some of the broken tablet was not added to the water.

The tablet was not crushed enough to make a substantial difference.

The size of the reaction beaker was varied.

The tablets were not uniform in their mass.

What is the molar mass of a gas that has density of 2.054 g/l

Convert the temperature of dry ice, –77 ∞c, into degrees fahrenheit and kelvin.

Consider the following unbalanced equation for the combustion of hexane: αc6h14(g)+βo2(g)→γco2(g)+δh2o(g) part a balance the equation. give your answer as an ordered set of numbers α, β, γ, use the least possible integers for the coefficients. α α , β, γ, δ = nothing request answer part b determine how many moles of o2 are required to react completely with 5.6 moles c6h14. express your answer using two significant figures. n n = nothing mol request answer provide feedback
