The equation of hooke's law is F=KX
Answer:
1)This type of reaction is called thermal decomposition . Copper carbonate is green and copper oxide is black. You can see a colour change from green to black during the reaction. The carbon dioxide produced can be detected using limewater, which turns milky. 2) The extremely low pressure of the partial vacuum inside the can made it possible for the pressure of the air outside the can to crush it. A can is crushed when the pressure outside is greater than the pressure inside, and the pressure difference is greater than the can is able to withstand.

<h3><u>Answer;</u></h3>
only in the n = 3 energy level
<h3><u>Explanation;</u></h3>
- <em><u>The atom of a chemical element is made up of sub-atomic particles which are the neutrons, protons and electrons.</u></em> The neutrons and protons occupies the nucleus of an atom while the electrons occupy the energy levels.
- <em><u>The first energy level (n=1) of an atom occupies a maximum of two electrons because it has only an S-orbital which can only have two electrons.</u></em>
- <u>The second energy level (n=2) can have a maximum number of 8 electrons, since it contains, one S- orbital which can hold two electrons, and a p-orbital which can accommodate six electrons.</u>
- <em><u>The third energy level (n=3) can have a maximum number of 18 electrons,</u></em> because it has <u><em>the S-orbitals which holds 2 electrons, the p-orbital which holds 6 electrons and the d-orbital which holds 10 electrons. </em></u>
Given the following equation: 2N2 + 5O2 → 2N2O5, the number of moles of N2O5 produced by reacting 6.0 moles of O2 is 2.4moles.
<h3>How to calculate number of moles?</h3>
The number of moles of a substance can be calculated stoichiometrically as follows:
2N2 + 5O2 → 2N2O5
Based on the above chemical equation, 5 moles of oxygen gas (O2) produces 2 moles of N2O5.
This means that if 6.0 moles of O2 reacts, 6 × 2/5 moles of N2O5 will be produced.
= 12/5 = 2.4moles of N2O5
Therefore, given the following equation: 2N2 + 5O2 → 2N2O5, the number of moles of N2O5 produced by reacting 6.0 moles of O2 is 2.4moles.

Conic sections are called quadratic relations, because the equations which describe them are second order and not always functions.
