Suppose the total volume of sand on the beach is 1,278m. What will the volume be after 24 hours of erosion?
agasfer [191]

Answer:

Let's assume that the erosion rate is "X/hour". The total volume of sand on a beach after 24 hours would be,

= total sand volume - (erosion rate per hour * 24)

= 1,278m - (X/hour * day)

Explanation:

Now assume that the erosion rate is 1 m per hour. Therefore, in 24 hours would be,

= 1,278m - (1/hour * 24)

= 1,278 - 24

= 1254 m.

For the following reaction, identify the element that was oxidized, the element that was reduced, and the reducing agent. Give a
Volgvan

<span>For this reaction, oxidation number of Carbon in CO would be +2 while oxidation number of carbon in CO2 would be +4 and so this means that carbon has oxidized. Oxidation number of nitrogen in NO is +2. While oxidation number of nitrogen in N2 is 0 so this means that nitrogen had reduced. The reducing agent is the one which provides electrons by oxidizing itself so in this case; CO is the reducing agent while the C in CO oxidized to produce electrons. </span><span>I am hoping that this answer has satisfied your query about and it will be able to help you, and if you’d like, feel free to ask another question.</span>
