What are the sources of error in a solubility lab containing potassium crystal
Some possible sources of lab error. 1. Not preciously measuring. 2 Air pressure (not being at STP). 3 Not all liquid evaporating when measuring a solid. 4 How many significant digits are used and when rounded
radius
There's temperature and elevation
3 main sources of error would be first that the cup is not closed and therefore a lot of the heat would not be kept in the cup. Also the pellets could have been either too hot or too cold when they were placed in the cup.
Measurements are off because the tool used isn't precise. Temperature and humidity may affect the results. Errors like miscalculations and reading scales incorrectly don't count as a lab error and would be a human mistake. For a formal lab, you shouldn't include these types of errors on your part.
Between shining and massing the copper wire, some Copper II Oxide formed. You can finish the rest; it's pretty self explanatory.
That's actually not possible. If one of the parents have a B gene genotype, then this could be possible. Or there could be a lab error. I recommend to get it checked again.
When one breeds a yellow Labrador retriever and a chocolate Labrador retriever one will have a yellow Labrador retriever with brown or chocolate pigmentation.
Sh1tty nerds answer the question
for example you use a beam balance to find the mass of a rock sample for a science lab. you read the scale as 3.8g. what is your greatest possible error? well the rocks mass was measured to the nearest 0.1g, so the greatest possible error is one half of 0.1g he's right but here's the definition: one half of the unit of measurement to which the measure is being rounded. EX. the greatest possible answer of 3g is 1.5g If you have 3 cm, you are measuring to the nearest cm, so the greatest possibel error would be .5 cm.
