Answer: molarity = mole solute/ liter of solution.
=> volume= mole/molarity = 1/5 = 0.2 L = 200mL
Explanation:
90% of energy is lost. only 10% is left.
therefore the answer is B. 90%
Answer:
Advantages: More land has been made available for development. More buildings and infrastructure can be built, and also for other reasons.
Disadvantages: Much greenery has been removed in order for the land needed. Land reclamation can be damaging to corals and marine life. Corals are usually moved to another place when land is to be reclaimed. The corals might not be able to survive in that certain habitat, and thus die out. In some countries, where the project is large-scale, they do not even bother to re-plant the corals elsewhere, instead just reclaim the land on their habitat, causing them to die out immediately. Marine life, such as fishes, might not have enough food after the underwater plantations are destroyed due to reclamation of land. This applies to the food chain. The waters might also be polluted from the soil used to reclaim land, causing the fishes to die and blocking out sunlight, depriving the underwater plants of growth. Marine habitats are also destroyed, as mentioned earlier; therefore, the marine creatures would be forced to move to another new habitat. Some might not be able to adapt, and thus die out. Some would just die without even finding a new habitat, as they cannot move long distances in water. Of course, the reasons and examples look tempting to us humans, but marine life is life too! We should try to protect is as much as possible, instead of just focusing on the advantages.
Answer:
A) Precision
B) Accuracy
C) Precision
D) Accuracy
Explanation:
<em>Accuracy</em> and <em>Precision </em>are factors that determine whether a given analysis is appropiate or not.
Accuracy refers to how close the experimental result is to a <em>known, theoretical or accepted value. </em>For this reason every method that checks the accuracy uses a standard -this could mean repeating the test using the standard instead of the sample, or adding a known amount of analyte to the sample-, in order to compare the results.
Precision refers to how close repeated the results of different tests are to each other, in other words, it refers to the <em>repeatability </em>of the method. A test for precision would require that the method is done several times, in order to check how close the results are to each other, regardless of whether those results are close to the expected value.
