Answer:
proton. neutrons and electrons
I think the answer is, Thermal? I hope u get it right
<u>Answer:</u> The change in internal energy of the gas is 29.414 kJ.
<u>Explanation:</u>
To calculate the temperature of the gas at different volumes, we use ideal gas equation:
- When volume =
We are given:
Conversion used: 
Putting values in above equation:
- When volume =
We are given:
Putting values in above equation:
- To calculate the change in internal energy, we use the equation:
where,
= change in internal energy = ?
n = number of moles = 4.0 mol
= heat capacity at constant volume = 
= final temperature = 1095.06 K
= initial temperature = 505.41 K
Putting values in above equation, we get:
Converting this value in kilojoules, we use the conversion factor:
1 kJ = 1000 J
So, 
Hence, the change in internal energy of the gas is 29.414 kJ.
Answer:
The volume of the solution is 133 ml
Explanation:
Having a 0.250 molar solution means 0.250 moles in 1000 ml of solution (1 liter)
We calculate the weight of 1 mole of CuNO3, and use 3 simple rules for calculations:
CuNo3---> Weight of 1 mole= 63, 546g+ 14, 0067g+ 3X 15, 9999g= 125, 55g/mol
1 mol----125, 55g
0,250mol---X= (0,250molx 125,55g)/1mol= 31,3 g
31,3g----1000ml
4,16g---x= (4,16gx1000ml)/31,3g = 133ml
Answer:
3
Explanation:
Atoms are made of 3 parts.
- The protons and Neutrons form together creating a sun, or nucleus at the center
- The electrons orbit this sun like planets.
The element with Th is Thorium. It is a metallic chemical element that when exposed to air, hardens.
