Answer:
2Na2O2+2H2O⟶O2+4NaOH
2×78g 32g
156g of Na2O2 produces 32g of O2,
12g of Na2O2 produces =15632×12=10.66g.
Density of O2 at NTP=1.428g/mL.
DensityMass=Vol.
1.42810.66=7.46mL
Vol. of O2 at NTP is 7.46mL.

Explanation:
The prefix inter- means between, reflecting that interphase takes place between one mitotic (M) phase and the next. Image of the cell cycle. Interphase is composed of the G1 phase (cell growth), followed by the S phase (DNA synthesis), followed by the G2 phase (cell growth).
Answer:8.933572
Explanation:
for an approximate result, multiply the volume value by 3.785
Answer: 180torr
Explanation:
Using P1VI/T1= P2V2/T2
where
p1= 650 torr
p2=??
T1= 27°C = 27°C + 273= 300K
T2= -183°C= -183°C +273=90K
V1= V2 ie volume is constant
SOLUTION
1 torr= 1mmHg
P1VI/T1= P2V2/T2, where V1=V2
= P1/TI= P2/T2
600/300=P2/90
P2= 600X90/300= 180 torr
