Calvin is practicing for a golf tournament. His normal driver distance is 250 yards. He hits three balls with his driver, and th
Oduvanchick [21]

Answer:

This question is incomplete as it lacks options; the options are:

A. His drives are both accurate and precise

B. His drives are precise but not accurate

C. His drives are accurate but not precise

D. His drives are neither accurate nor precise

The correct answer is B. His drives are precise but not accurate

Explanation:

The accuracy of a measurement refers to how close those measurements are to a true or accepted value. Note that, in this case, the normal driver distance of 250 yards is the TRUE OR ACCEPTED VALUE. Observing the three measured values for the driver's distance; 270 yards, 273 yards, and 269 yards, one would notice that these values are far apart from the true value of 250yards. Hence, these measurements are NOT ACCURATE.

On the other hand, PRECISION refers to how close measurements are to one another. In this case, 270yards, 273 yards, 269 yards are close to one another, hence that are said to be PRECISE.

Therefore, according to the measurements, it can be said that HIS DRIVES ARE PRECISE BUT NOT ACCURATE

If 14 moles of gas are added to a container that already holds 1 mole of gas, the pressure inside the container _ due to change
ioda

Answer:

The pressure inside the container will increase by increasing the amount of gas.

Explanation:

It can be better understand through ideal gas equation,

PV = nRT

By keeping the volume and temperature constant, the pressure of gas in container will increase when amount of gas goes to increase.

PV = nRT

P = nRT / V

P = (1+ 14) RT/V

P = 15

The pressure will increase 15 fold.

How can you identify a chloride from an iodide solution using the silver nitrate and sodium thiosulfate test?
scoundrel [369]
For the silver nitrate test, the solution is added first with nitric acid. This test is to determine halide ions. When silver nitrate is added to the solution, the color of the precipitate would indicate the identity of the ion. For chloride ions, the precipitate is white.

For the sodium thiosulfate test, chlorine is treated with Ki solution which turns brown. When it is titrated with sodium thiosulfate solution, the brown turns yellow upon which, starch is added. It forms a complex which appears as dark blue. Upon adding more titrant, it reaches the endpoint where the blue turns colorless.
