Answer:
A volume of 236 L and a temperature of 10.0 ° C has a pressure of 25.3 kPa.
Explanation:
Boyle's law says that "The volume occupied by a certain gaseous mass at constant temperature is inversely proportional to pressure." Boyle's law is expressed mathematically as: P * V = k
Gay-Lussac's law can be expressed mathematically as follows:
This law indicates that when there is a constant volume, as the temperature increases, the pressure of the gas increases. And when the temperature is decreased, the pressure of the gas decreases.
Finally, Charles's Law consists of the relationship between the volume and the temperature of a certain amount of ideal gas, which is kept at a constant pressure. This law is a law that says that when the amount of gas and pressure are kept constant, the quotient between the volume and the temperature will always have the same value:
Combined law equation is the combination of three gas laws called Boyle's, Charlie's and Gay-Lusac's law:
Studying two different states, an initial state and a final state, you have:
In this case:
- P1= 50.7 kPa
- V1= 120 L
- T1= 15 C= 288 K (being 0 C= 273 K)
- P2= ?
- V2= 236 L
- T2= 10 C= 283 K
Replacing:
Solving:
P2= 25.3 kPa
<u><em>A volume of 236 L and a temperature of 10.0 ° C has a pressure of 25.3 kPa.</em></u>

Answer:
After 30 cycles, as many as a billion copies of the target sequence are produced from a single starting molecule
Atomic mass Ca = 40.078 u.m.a
40.078 g --------------- 6.02x10²³ atoms
121 g ------------------- ??
121 x ( 6.02x10²³) / 40.078 =
7.28x10²⁵ / 40.078 = 1.81x10²⁴ atoms
Answer:
0.631 grams is the theoretical yield of solid copper (Cu) that can be recovered at the end of the experiment
Explanation:
The concentration of the solution is given by :
We have:
Concentration of copper (II) nitrate solution =
The volume of solution = 4.12 mL
1 mL= 0.001 L
Moles of copper (II) nitrate in solution = n
Moles of copper (II) nitrate in solution = 0.0099292 mol
1 Mole of copper(II) nitrate has 1 mole of copper then 0.0099292 moles of copper(II) nitrate will have :
Mass of 0.0099292 moles of copper:
This mass of copper present in the solution is the theoretical mass of copper present in the given copper(II) nitrate solution.
0.631 grams is the theoretical yield of solid copper (Cu) that can be recovered at the end of the experiment
Answer: A=1, B=3, C=12
Explanation:
For this problem, you will need to know your unit conversions. There are 3 ft in 1 yard. Knowing this, we can find A, B, C.
For A and B, we know that we want to cancel out ft so the answer can be in yards. To do so, we need to put B=3 and A=1.
Now that we know the unit conversion, we can directly solve.
36 ft×(1 yd/3 ft)=12 yd
Our final answer is A=1, B=3, C=12.
