<h2>What happens for elements larger than iron to be created? </h2>
- Neutron-capture inside stars is the primary source of elements heavier than iron, while there are other minor contributors (cosmic ray spallation, radioactive decay). They are not just produced by supernovae, but also by other stars.
Answer:
............. the need of _Nitrogen, phosphorus and potassium_
Explanation:
Each of these fundamental nutrients plays a key role in plant nutrition. ... It's also needed to help plants grow and develop normally. Phosphorus in commercial fertilizers comes from phosphate rock.
We determine the mass of the metal in grams by weighing it using the balance.
Next we obtain the volume of the metal by measuring its displacement with a graduated cylinder and water in the following way:
1.measure amount of water in the graduated cylinder.
2. Place metal into the graduated cylinder
3. Measure the amount of water in the graduated cylinder
4. Subtract step 1 from step 3. The difference is the metal's volume.
Once we have found out the mass and the volume then we calculate the density using the formula:
Density = Mass/Volume.
We then check our answer from the known densities of metals in the table of densities that has been provided and determine the identity and purity of the metal by how close our answer is to the most probable value in the table.
