Answer:
(4) 230 kPa
Explanation:
The temperature is constant, so the only variables are pressure and volume.
We can use Boyle’s Law.

Divide both sides of the equation by
.




Answer:
Microliters = 
Explanation:
SI unit of volume is liter.
..............................(1)
1dm=10cm
.................(2)
replacing value of
from equation (1) in equation (2)
...................(3)
but
....................(4)
replacing value of 1 liter from equation (3) in equation (4)

on solving further ,we get



Microliters = 
Answer:
It is carbon dioxide
Explanation:
<h2>All source relies on it Because if they dont have it then its not considered a source of anything else.</h2>
Sharing of electrons always means its a covalent bond, and unequal means it is polar, so it is a polar covalent bond
The balanced equation for the above reaction is as follows;
2C₈H₁₈ + 25O₂ ---> 16CO₂ + 18H₂O
stoichiometry of octane to CO₂ is 2:16
number of C₈H₁₈ moles reacted - 191.6 g / 114 g/mol = 1.68 mol
when 2 mol of octane reacts it forms 16 mol of CO₂
therefore when 1.68 mol of octane reacts - it forms 16/2 x 1.68 = 13.45 mol of CO₂
number of CO₂ moles formed - 13.45 mol
therefore mass of CO₂ formed - 13.45 mol x 44 g/mol = 591.8 g
mass of CO₂ formed is 591.8 g
