Answer:
b. All rocks are made of minerals.
Explanation:
A rock is a mixture of two or more minerals. It does not usually have a specific shape. Granite consists of several different minerals.
A mineral has a specific composition in which the atoms occupy positions in a crystal lattice. Minerals like halite usually have a characteristic crystal shape.
Thus, all rocks are made of minerals, but minerals are not made of rocks.
Answer:
24.6 atm
Explanation:
Step 1: Given and required data
- Pressure of carbon dioxide (P): ?
- Volume of carbon dioxide (V): 1.00 L
- Moles of carbon dioxide (n): 1.00 mol
- Ideal gas constant (R): 0.08206 atm.L/mol.K
- Temperature of carbon dioxide (T): 300 K
Step 2: Calculate the pressure of carbon dioxide
Assuming ideal gas behavior, we will use the ideal gas equation.
P × V = n × R × T
P = n × R × T/V
P = 1.00 mol × 0.08206 atm.L/mol.K × 300 K/1.00 L
P = 24.6 atm
Answer:
ions
Explanation:
if you have telekinesis and you move a pencil the ions are the ones moving it the ions that are in our bodies are different with the ones in the air that's why sometimes when it rains some of us get sick it's because the ions that are in the air enter into our bodies
Zinc will always have 30 protons, so you'd have 66-30 = 36 neutrons
I hope it helped you!
Answer:
0.2886 atm is the osmotic pressure of a solution.
Explanation:
Osmotic pressure of solution =![\pi](https://tex.z-dn.net/?f=%5Cpi)
Concentration of the solution = c
Mass of the ammonium sulfate = 1.502 g
Moles of ammonium sulfate = ![\frac{1.502 g}{132.16 g/mol}=0.01136 mol](https://tex.z-dn.net/?f=%5Cfrac%7B1.502%20g%7D%7B132.16%20g%2Fmol%7D%3D0.01136%20mol)
Volume of the solution = 1 L
Concentration of the solution:
![=\frac{\text{Moles of ammonium sulfate}}{\text{Volume of the solution}}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B%5Ctext%7BMoles%20of%20ammonium%20sulfate%7D%7D%7B%5Ctext%7BVolume%20of%20the%20solution%7D%7D)
![c=\frac{0.01136 mol}{1 L}=0.01136 mol/L](https://tex.z-dn.net/?f=c%3D%5Cfrac%7B0.01136%20mol%7D%7B1%20L%7D%3D0.01136%20mol%2FL)
Temperature of the solution ,T= 36.54°C = 309.69 K
R = universal gas constant = 0.08206 L atm/mol K
![\pi=cRT](https://tex.z-dn.net/?f=%5Cpi%3DcRT)
![\pi=0.01136 mol/L\times 0.08206 L atm/mol K\times 309.69 K](https://tex.z-dn.net/?f=%5Cpi%3D0.01136%20mol%2FL%5Ctimes%200.08206%20L%20atm%2Fmol%20K%5Ctimes%20309.69%20K)
![\pi=0.2886 atm](https://tex.z-dn.net/?f=%5Cpi%3D0.2886%20atm)
0.2886 atm is the osmotic pressure of a solution.
