Answer:
Proton: m= 1.6726x10⁻²⁷ kg
Neutron: m= 1.6749x10⁻²⁷ kg
Electron: m= 9.1164x10⁻³¹ kg
Explanation:
<u>We can calculate the mass of a proton, neutron, and electron using the following data:</u>
<em>mass of proton</em>: 1.00728 amu
<em>mass of neutron</em>: 1.00867 amu
<em>mass of electron</em>: 5.49x10⁻⁴ amu
<em>1 amu</em> = 1.66054x10⁻²⁷ kg
Now, the mass of a proton, neutron, and electron in kilograms can be calculated using the next relation:
For the proton:
For the neutron:
For the electron:

<u><em>An environmental factor is a characteristic of the environment that changes how an organism interacts with the environment</em></u>
Explanation:
Hope this helps:)
Because the earth wouldn't be able to exist without the help of the sun, the sun is essential for earth.
Answer::
<u><em>Lower rate of reaction</em></u>
Explanation:
Lower concentration of reactant in an experiment is indicative of fewer ions or atoms present, which means a slower rate of reaction. In a titration reaction for instance, the end point would take longer to be substantiated, thereby increasing volume of titres. This is further backed up by collision theory which states that more particles in a system improves combinations of molecules.
This however may not be the case if the iodine in question is catalyst, in which case the change in concentration has no effect whatsoever on the reaction rte.
I hope this explanation fits the brief.
