Answer:
the nuclear envelope disappears
Explanation:
Answer:
B
Explanation:
A chemical change occurred, and this caused the liquid’s physical properties to change.
when we read her experiment we can see that color changed to blue, it is because new products are formed. And the temperature cause this.
Answer:
3. 0.36 L to the nearest hundredth
4. 542.40 L to the nearest hundredth
Explanation:
Question 3
Volume = 8.16 L
Number of moles = ?
At STP;
Temperature = 273 K
Pressure = 1 atm
Using the General gas equation;
PV = nRT where R = General gas constant = 0.0821
n = PV / RT
n = (1 * 8.16 ) / (0.0821 * 273)
n = 8.16 / 22.4133 = 0.3641 ≈ 0.36 to the nearest hundredth
Question 4
Volume = ?
Number of moles = 24.2 mol
At STP;
Temperature = 273 K
Pressure = 1 atm
Using the General gas equation;
PV = nRT where R = General gas constant = 0.0821
V = nRT / P
V = 24.2 * 0.0821 * 273 / 1
V = 542.402 L ≈ 542.40 to the nearest hundredth
