Answer:
His drives are neither precise not accurate
Explanation:
It is true that his drives are neither precise nor accurate.
Accuracy is the exactness of measurement. It is the closeness of measured values to the true values.
In this problem, the true value is 250 yards, the measured values are 190 yards, 195 yards and 187 yards.
We can conclude that these numbers are very far from the true values. By virtue of that, they are inaccurate.
Precision is the ability to reproduce a set of experimental values. It is the closeness of the measured values to one another.
Jared failed to replicate his measured values over the three trials and so, his readings are not precise.
Therefore, his measurements are both imprecise and inaccurate.
I’m assuming in this scenario that 2.5 mols of Fe2O3 is reacting with excess reactant. Based on the balanced equation, you can see that there’s a 1:2 ratio between Fe2O3 and Fe. This means that to find the mols of Fe formed, you need to multiply the mols of Fe2O3 by 2.
2.50mol Fe2O3 * 2mol Fe/1 mol of Fe2O3 = 5.00mols Fe.

Answer:
Like most Earth materials, rocks are created and destroyed in cycles. The rock cycle is a model that describes the formation, breakdown, and reformation of a rock as a result of sedimentary, igneous, and metamorphic processes. All igneous rocks start out as melted rock, (magma) and then crystallize, or freeze.
