<span> 1C3H8(g) + 5 O2(g) → 3 CO2(g) + 4 H2O, the ∆H is –2200 kJ
1mol </span>C3H8(g) ---- –2200 kJ
2mol C3H8(g) ----2(–2200 kJ)=-4400kJ
Answer:
Some areas of the body are more sensitive than others because they have more nerve endings. It hurts when you bite your tongue because the sides of your tongue have a lot of nerve endings that are very sensitive to pain! The tongue, lips, and fingertips are the most touch-sensitive parts of the body. The parts of your skin that need to be most sensitive like your fingertips and your lips have more receptor cells in them than others less sensitive areas. The least sensitive skin on the human body is found in the heel area. This is because there are very few nerves in the heel to feel things. If there were too many nerves in our heels then walking would be far too painful.
Explanation:
Answer:
12.01
Explanation:
(12.00*98.93% + 13*1.07%) /100% = 12.01
The answer
<span>the molar ratio for the following equation
____C3H8 + ____O2 Imported Asset ____CO2 + ____ H2O
</span>after it has been properly balanced:
__1_C3H8 + ____5O2 Imported Asset ____3CO2 + ____ 4H2O
proof:
number of C =3 (C3H8; 3CO2)
number of H =8 (C3H8 ; 4H2O)
number of O = 10(5x2) or (2x3+4) (5O2;4H2O)
the answer is
<span>Reactants: C3H8 = 1, O2 = 8; Products: CO2 = 3 and H2O = 4</span>
if 105 grams burns completely
therefore
105 ×22.4/48=49
