Spring tides is when the daily tidal range is greatest and neap tides are when the daily tidal range is the smallest. As for alignment, spring tides occur when the earth, moon, and sun are directly in alignment with each other. Neap tides occur when the earth is in alignment with the sun, but the moon is at a 90 degree angle from that
The spring tides occur seven days after the spring tide and the spring tides occur twice in the lunar year.
Explanation:
A spring tide is a tide in which there is a greatest difference between a high and low tide is the greatest. A spring tide occurs when the earth, the moon, and the sun are in the straight line. A neap tide, on the other hand, occurs when the sun, moon, and earth make a three triangle kind of a triangle. It occurs when there is a least between the highest and lowest tide.
Neap tides occur twice a month when the sun and moon are at right angles to the earth. Spring tide, on the other hand, occur at new moon or full moon
Answer:- is a reducing agent, is an oxidizing agent and is neither.
Solution:- We write the oxidation numbers for all the elements and see for which of them it's changing. An increase in oxidation number is oxidation and a decrease in oxidation number is reduction. What is being oxidized acts as a reducing agent and what is being reduced acts as an oxidizing agent.
Oxidation number of N in is +3 and O is -2 . Oxidation number of H in is +1 . Oxidation number of Cr in is +6 and O is -2 .
Oxidation number of N in is +5 and O is -2. Oxidation number of Cr in is +3. oxidaton numbers of H and O in water are +1 and -2 respectively.
Looking at all of these only the oxidation number of N is increasing from +3 to +5 which indicates oxidation and so is a reducing agent.
Oxidation number of Cr is decreasing from +6 to +3 which indicates reduction and so is an oxidizing agent.
Oxidation numbers of H and O are not changing and hence is neither oxidizing nor reducing agent.
