The number of protons and neutrons in the nucleus.
Answer:
12.1 kJ
Explanation:
For this problem, we are going to use the Arrhenius Equation.
![ln(\frac{k_{2} }{k_{1}})=\frac{E_{a} }{R} (\frac{1}{T_{1}} -\frac{1}{T_{2}} )\\ln(\frac{2}{1} )=\frac{E_{a} }{8.314} (\frac{1}{300}-\frac{1}{350} )](https://tex.z-dn.net/?f=ln%28%5Cfrac%7Bk_%7B2%7D%20%7D%7Bk_%7B1%7D%7D%29%3D%5Cfrac%7BE_%7Ba%7D%20%7D%7BR%7D%20%28%5Cfrac%7B1%7D%7BT_%7B1%7D%7D%20-%5Cfrac%7B1%7D%7BT_%7B2%7D%7D%20%29%5C%5Cln%28%5Cfrac%7B2%7D%7B1%7D%20%29%3D%5Cfrac%7BE_%7Ba%7D%20%7D%7B8.314%7D%20%28%5Cfrac%7B1%7D%7B300%7D-%5Cfrac%7B1%7D%7B350%7D%20%29)
We are going to solve for activation energy,
.
kJ
It depends on the weight and the high and the location of the object. I hop I helped. Have a great day
Answer:
We have the final answer as
<h2>0.8 g/cm³</h2>
Explanation:
The density of a substance can be found by using the formula
![density = \frac{mass}{volume} \\](https://tex.z-dn.net/?f=density%20%3D%20%20%5Cfrac%7Bmass%7D%7Bvolume%7D%20%5C%5C)
From the question
mass of pumpkin = 8 g
volume = 10 cm³
It's density is
![density = \frac{8}{10} = \frac{4}{5} \\](https://tex.z-dn.net/?f=density%20%3D%20%20%5Cfrac%7B8%7D%7B10%7D%20%20%3D%20%20%5Cfrac%7B4%7D%7B5%7D%20%20%5C%5C%20)
We have the final answer as
<h3>0.8 g/cm³</h3>
Hope this helps you
