Explanation:

A rate law shows how the rate of a chemical reaction depends on reactant concentration. For a reaction such as aA → products, the rate law generally has the form rate = k[A]ⁿ, where k is a proportionality constant called the rate constant and n is the order of the reaction with respect to A.

slega [8]

Answer:

295.96 K ( = 22.81 degrees C)

Explanation:

PV = n RT R = .082057 L-Atm / (K-Mol) n = 3.5 P = 1 atm V = 85 liters

(1)(85) = 3.5 (.082057)(T)

solve for T = 295.96 K

A zinc slug comes from a science supply company with a stated mass of 5.000 g. A student weighs the slugthree times, collecting

Answer: The student’s values are accurate as well as precise.

Explanation:

Precision refers to the closeness of two or more measurements to each other.

For Example: If you weigh a given substance three times and you get same value each time. Then the measurement is very precise.

Accuracy refers to the closeness of a measured value to a standard or known value.

For Example: If the mass of a substance is 50 kg and one person weighed 49 kg and another person weighed 48 kg. Then, the weight measured by first person is more accurate.

Given: Mass = 5.000 g

Mass weighed by A has values 4.891 g , 4.901 g and 4.890. Thus the average value is $\frac{4.891+4.901+4.890}{3}=4.894$

Thus as the measured value is close to the true value, the student’s values are accurate and as the values are close to each other, the measurement is precise.
