What happens during rusting of an iron nail? (1 point)
Sulfur and oxygen combine to form a sulfur dioxide coating.
O Sulfur, iron, and oxygen combine to form iron sulfoxide.
O Iron and oxygen combine to form iron oxide.
O Iron and sulfur combine to form iron sulfide.
Answer:
C) Iron and oxygen combine to form iron oxide
Explanation:
Iron react with oxygen to form iron oxide in the rusting of iron nails.
The nails of iron is made up of iron that is unstable which reacts with oxygen that is present in the air that lead to rusting of iron nails. This reaction can be prevented by painting the metal that covers the surface and prevent the reaction of iron and oxygen which results in the long life of iron materials. The rusting of iron deteriorates the metals which causes in the reduction in the life of iron materials so we can conclude that iron reacts with oxygen results in the rusting of iron nails.

If the producer level of the energy pyramid start with 5000 calories how many calories will transfer to the secondary consumers
Explanation:
Only 10% of calories will be transfered to the next higher level.
5000 * 0.1 = 500.
500 calories will transfer to the secondary consumers.
The number of calories that will be transferred to secondary consumers will be-
10% of 5000 = 500 and
10% of 500 =50 calories.
What is the ten percent law?The ten percent law explains the energy transfer among the trophic levels in a food chain. It was given by Raymond Lindemann.
According to this law, when the energy is transferred from one trophic level to the next, ninety percent of the energy is lost in the form of heat and only ten percent of the energy is received by the next trophic level.
For example, if an energy level or a trophic level has 10,000 calories, only ten percent will be received by the next energy level which is 1000 calories.
In an ecosystem, energy is produced by primary producers. If the primary producers start with 5000 calories of energy, the energy received by the next trophic level, i.e by the primary consumers will be ten percent of 5000. This will be equal to 500.
Therefore the energy received by secondary consumers will be ten percent of 500, which will be equal to 50 calories.

Prompt: Explain what the Big Bang theory is using evidence that supports the theory
oo, The Big Bang theory predicts how much of each element should have been made in the early universe, and what we see in very distant galaxies and old stars is just right. You cannot look in new stars, like the Sun, for this evidence, because they contain elements that were created in previous generations of stars.
