Since nickles atomicnumber is 28, that means it has 28 protons, which are positively charged. To cancel out the positive charge and make it nuetral, there isalso 28 electrons which are negatively charged.
Nickel has 31 neutrons because an atoms mass is the number of protons + neutrons. The # of protons is 28. The mass # is 59. So, there are 31 neutrons.
Besides nylon, HCl is formed from the reaction of adipoyl chloride and 1,6- diaminohexane , but HCl is the byproduct molecule.
<h3>What is formed when adipoyl chloride and 1,6-diaminohexane reacts with each other and what are the by products?</h3>
- Adipoyl chloride is the monomer and hexamethylinediamine is also the monomer which reacts together to form polymer.
- The polymer formed is named nylon6,6 which is a co polymer and nylon 6,6 find its use in various other activities of life.
- Nylon6,6 is a copolymer since the participation of two monomers , and not a single monomer undergoing decomposition.
- Nylon6,6 is formed with an elimination of small molecule of HCl which is considered to be a by product .
- It is formed by a condensation reaction and hence HCl is the product formed from the reaction of adipoyl chloride and 1,6- diaminohexane.

Your body is slowly failing and becoming weaken to the onslaught of the disease you are fighting, till one by one your major components of life start to fail until death comes if it is serious enough.
Answer:
density is a ratio of mass to volume
Explanation:
density=mass/volume
1=mass/125
mass=1 x 125
mass=125g
pardon my not typing units during solution
Answer:
The temperature increases in 40.9K
Explanation:
Based on the reaction, 4 moles of aniline in combustion releasing 12800kJ to the surroundings, in this case, to the calorimeter.
To solve this question we must find the heat that releases the sample of aniline finding the moles in the sample.
With the heat released we can find the increase in Kelvin due the combustion as follows:
<em>Moles aniline:</em>
11.9g * (1mol / 93g) = 0.128 moles aniline
<em>Heat released:</em>
0.128 moles Aniline * (12800kJ / 4 moles Aniline) = 409kJ are released
<em>Increasing in temperature:</em>
For each 10.0kJ, the calorimeter increases its temperature in 1K. For 409kJ:
409kJ * (1K / 10.0kJ) =
<h3>The temperature increases in 40.9K</h3>
