So to answer this we will use the next procedure:
<span>First balance the equation:
2 C6H5OH + 15 O2 --> 12 CO2 + 6 H2O
Phenol (C6H5OH) reacts with O2 in a 2:15 ratio.
This means:
moles phenol 2 / moles O2 = 2 / 15
moles phenol = (2/15)*0.200 = 0.0267
Molar mass of phenol is 94 g/mol
Mass of phenol would = 0.0267*94 = 2.5 g
</span>I hope this can help
I think it’s b I’m not sure so sorry if incorrect. Take care.
Answer:
pOH=11.3
Explanation:
pH= -log[H+]=-log[0.002]=2.7
pOH+pH = 14
pOH= 14-2.7=11.3
Answer:
1. desert
2. grasslands
3. rainforest
4. tundra
5. temperate deciduous forest
6. coniferous forest
Explanation:
educated guess, good luck
Answer:
Equation correctly showing the heat of solution

Explanation:
Mass of aqueous solution = m = 100 g
Specific heat of solution = c = 4.18 J/gºC
Change in temperature = 
ΔT = 21.6ºC - 30.0ºC = -8.4ºC
Heat lost by the solution = Q


Q = -3,511.2 J ≈ -3.51 kJ
Heat absorbed by potassium nitrate when solution in formed; Q'
Q' = -Q = 3.51 kJ
Moles of potassium nitrate , n= 

The heat of solution =

So, the equation correctly showing the heat of solution
