Answer:
The regrouping of the two systems affect the components because they either don't work together or other...
Explanation:
Answer:
The volume of the gas will be 78.31 L at 1.7 °C.
Explanation:
We can find the temperature of the gas by the ideal gas law equation:
Where:
n: is the number of moles
V: is the volume
T: is the temperature
R: is the gas constant = 0.082 L*atm/(K*mol)
From the initial we can find the number of moles:
Now, we can find the temperature with the final conditions:
The temperature in Celsius is:
Therefore, the volume of the gas will be 78.31 L at 1.7 °C.
I hope it helps you!
Answer:
true
Explanation:
PV=nRT
The ideal gas law states that PV = NkT, where P is the absolute pressure of a gas, V is the volume it occupies, N is the number of atoms and molecules in the gas, and T is its absolute temperature. The constant R is called the Boltzmann constant
Answer:
The correct answer is 16.8 g (option C)
Explanation:
Step 1: Data given
9.78 grams + 7.0 grams
Rule significant numbers say:
⇒ Non-zero digits are always significant.
⇒ Any zeros between two significant digits are significant.
⇒ A final zero or trailing zeros in the decimal portion ONLY are significant.
For addition and subtraction, look at the places to the decimal point. Add or subtract in the normal way, then round the answer to the LEAST number of places to the decimal point of any number in the problem.
9.78 g+ 7.0 g = 16.78 grams
Significant numbers = 1 decimal
16.78 ⇒ 16.8
The correct answer is 16.8 g (option C)
