Spongebob was trying to make Krabby Patties that weighed 12oz. He made 4 Krabby Patties. They all had the following weights: 12.12oz; 11.9oz; 12.2oz; 12.1oz. Is this an example of Accuracy? Precision? Both? Neither?

Yes, the 4 Krabby patties are an example of high precision.

Explanation:

Precision is the closeness of the values obtained by applying them to the same parameter. To calculate the precision, the closeness of each of the values with the mean must be determined, all the values will be taken by subtracting the mean and the values will be taken into account to know which are the most accurate.

(12.12 + 11.9 + 12.2 + 12. 1) / 4 = 12.08

12.12 - 12.8 = 0.04

11.9 - 12.08 = - 0. 18

12.2 - 12.08 = 0.12

12.1 - 12.08 = 0.02

The most accurate precision is that of the fourth Krabby Pattie and the least precise is that of the second.

answer: the value of enthalpy change will be -152.80 kj.

solution:

pressure = 1atm , temperature = = 298 k

given that pressure and temperature are same in both gases , the number of moles of both gases can be determined by the ideal gas equation.

according to reaction 3 moles no are reacting with 1 mol of ,then 0.49 mol of no will react with moles of ozone that is 0.16 moles of ozone. since, no is limiting reagent and is an excessive reagent.

enthalpy change for the reaction between the given volumes of the gases is :
