Answer: number of electron in respective sub shell or orbital
Explanation:
Answer:
V = 15.9512 dm³
Explanation:
Given data:
Pressure = P = 1.37 atm
Temperature = T= 315 K
Number of moles of nitrogen= n = 0.845 mol
Volume = V = ?
Formula:
PV = nRT
Now we will put the values in equation.
V = nRT/ P
V = ( 0.845 mol× 0.0821 dm³.atm.K⁻¹.mol⁻¹ × 315 K) / 1.37 atm
V = 21.853 dm³. atm/ 1.37 atm
V = 15.9512 dm³
Answer:
1.When you put a plant in sunlight it grows better
3.When you have a plant in your house you breathe better
Explanation:
i dont have an answer for the second one tho
Answer: option 3. 5.46 L
Explanation:
1)<u> Data</u>
2) <u>Chemical principle</u>
<u />
- Combined law for ideal gases:
3) <u>Solution</u>
a) Conversion of units
The ideal gas law is valid for temperature in absolute units (Kelvin); hence, you have to converte °C to K.
- T₁ = 55.0 + 273.15 K = 328.15 K
- T₂ = 59.0 + 273.15 K = 332.15 K
b) Clear V₂ from the combined law of gases
c) Substitute values and compute
The answer must be reported with three significant figures, which is the number used for the data.
Answer: the gas will ocupy 5.46 liter at the new condictions of pressure and temperature.
1 lb=453.592 grams
So he gained 453.592 pounds
