Answer:
The carbon footprint of one plastic bottle of mass 23.5 g is 34.390 g.
Explanation:
The carbon footprint of one plastic bottle can be estimated by simple rule of three. That is:


The carbon footprint of one plastic bottle of mass 23.5 g is 34.390 g.
A: The Equator To The Poles
C5H12 + 8 O2 → 5 CO2 + 6 H2O
8 molecules of O2 are required.
Pressure is 5.7 atm
<u>Explanation:</u>
P1 = Standard pressure = 1 atm
P2 = ?
V1 = Volume = 10L
V2= 2.4L
T1 = 0°C + 273 K = 273 K
T2 = 100°C + 273 K = 373 K
We have to find the pressure of the gas, by using the gas formula as,

P2 can be found by rewriting the above expression as,

Plugin the above values as,

Answer: 2.7moles
Explanation:
6Cs + Fe2(CO3)3 —> 3Cs2CO3 + 2Fe
From the equation,
6moles of Cs produced 3 moles of Cs2CO3.
Therefore, 5.34 moles of Cs will produce = (5.4x3)/6 = 2.7moles of Cs2CO3
