A chemical element is a substance that is made up of only one kind atom.
Answer:
6 electrons
Explanation:
The p orbital can hold up to six electrons. We'll put six in the 2p orbital and then put the next two electrons in the 3s.
<u>Answer:</u> The final temperature of the coffee is 43.9°C
<u>Explanation:</u>
To calculate the final temperature, we use the equation:
![q=mC(T_2-T_1)](https://tex.z-dn.net/?f=q%3DmC%28T_2-T_1%29)
where,
q = heat released = ![1.0\times 10^3J=1000J](https://tex.z-dn.net/?f=1.0%5Ctimes%2010%5E3J%3D1000J)
m = mass of water = 10.0 grams
C = specific heat capacity of water = 4.184 J/g°C
= final temperature = ?
= initial temperature = 20°C
Putting values in above equation, we get:
![1000J=10.0g\times 4.184J/g^oC\times (T_2-20)\\\\T_2=43.9^oC](https://tex.z-dn.net/?f=1000J%3D10.0g%5Ctimes%204.184J%2Fg%5EoC%5Ctimes%20%28T_2-20%29%5C%5C%5C%5CT_2%3D43.9%5EoC)
Hence, the final temperature of the coffee is 43.9°C
Answer:
Because it keeps track of all the elements
Given:
Density = 0.7360 g/L.
Pressure = 0.5073 atm.
