Assume that each tablet's mass was 1,000 mg, and remember that you used 0.200 L of water each time. Compute the reaction rate to the nearest whole number using the formula below.
Answers
Answer:
For every temperature you use the formula given by the question.
at 3°C you have:
Reaction rate = (1000/0.2)/138.5 = 36 mg/L/sec
at 24°C you have:
Reaction rate = (1000/0.2)/34.2 = 146 mg/L/sec
at 40°C you have:
Reaction rate = (1000/0.2)/26.3 = 190 mg/L/sec
at 65°C you have:
Reaction rate = (1000/0.2)/14.2 = 352 mg/L/sec

Answers
The answer is: D. Biological precipitation.
Biological precipitation is the deposition of minerals from solution by the agency of organisms.
Deposition is the geological process in which sediments, soil and rocks are added to a landform or land mass.
Ocean sediments originate from numerous sources:
1) biological activity (biogenous).
2) weathering and erosion of the continents (terrigenous/lithogenous).
3) volcanic eruptions (volcanogenous).
4) chemical processes (hydrogenous).
Calcium carbonate (CaCO₃) is made of calcium, carbon and oxygen atoms.

Answers
This might be right. Im not quite sure. This is what my 5th grade science teacher told me. 'Look at the 2 LR's and add them together. Then look at the total amount which is 32. When you add the 2 LR's you get 17. So subtract 17 from 32 and you get 15. So: C:15 is your answer." (LR's stands for liquid reactants)
10+17=17
Total amount is 32
32-17=15
15 is you mass

Answer:
atoms are neutral or they have equal number of proton and electron but ions can be cation(positively charged) or anion(negatively charged) based on the number of electron the atm lose and gain respectively
Final answer:
An atom is the smallest unit of matter, with a neutral charge. An ion, however, is an atom that has either gained or lost electrons, giving it a net positive or negative charge. The difference between an atom and an ion is thus primarily about their charge.
Explanation:
An atom is the fundamental unit of matter made up of protons, neutrons, and electrons. In a neutral atom, the number of electrons (which carry a negative charge) equals the number of protons (which carry a positive charge). This makes the overall charge of an atom neutral.
An ion, on the other hand, is an atom that has gained or lost electrons, thus it has a net charge, as the number of electrons does not equal the number of protons. Positive ions, or cations, form when an atom loses electrons, and negative ions, or anions, form when an atom gains electrons.
For example, the anion of chlorine is chloride, and the anion of sulfur is sulfide. The difference between an atom and an ion, therefore, lies primarily in their charge, stemming from the shift in the balance between their numbers of protons and electrons.
