Answer:The answer to the question is the release of energy. The bonds that bind a molecules atom's act as a storage of energy. One way it is released is when those bonds are broken and it is released outward in every direction. This breakage results in smaller molecules and not the formation of a larger molecule.
Explanation:
Answer:
See figure 1
Explanation:
In the structure of nylon 6,6 we have <u>amide groups</u>. In this functional group, We have a nitrogen bond to hydrogen, so in this bond, we will have a <u>dipole</u>, due to the <u>electronegativity difference</u>. Nitrogen has more electronegativity than hydrogen, therefore a <u>positive dipole</u> would be generated in the hydrogen atom. Additionally, in the <u>carbonyl group</u> (C=O) due to the oxygen, we will have also a <u>dipole</u>, in this case, a <u>negative dipole</u> because the oxygen atom has <u>more electronegativity</u> (compare with carbon).
When we put two strings of nylon 6,6 the positive dipole will interact with the negative dipole and vice-versa and we will obtain the <u>"hydrogen bonds"</u>.
See figure 1
I hope it helps!
The answer is (3) 3. The calculation rule of significant figures is when multiplication and division, the significant figures of result is equal to the least of the numbers involved. The significant figure of 2.70 and 80.01 is 3 and 4.
Answer:
potassium, nitrogen and phosphorous cycle
Explanation:
A fertilizer is a substance which is applied on the plants by farmers to increase the supply of nutrients for the plants. Fertilizers have known to be toxic in many ways such as they alter the potassium, nitrogen and phosphorus cycles. Nitrogen, potassium and phosphorus are present in abundant amounts in the fertilizers. Draining of these fertilizers into rivers and ponds is toxic for the aquatic life. Hence, the use of fertilizers disrupts the natural cycles and is toxic for many aquatic plants and animals.
<span>We can use rocks to determine if the animals from to day have changed from the past.
Rocks also help us know if rivers once flowed through an area.
We use them to find out what type of animals live then that are extinct now.</span>
