Answer:
C₇ H₁₆ + 11O₂ → 7CO₂ + 8H₂O
Explanation:
Given equation
C₇ H₁₆ + O₂ → CO₂ + H₂O
To solve this problem,
We use a mathematical approach to balance the equation:
aC₇ H₁₆ + bO₂ → cCO₂ + dH₂O
Conserving C; 7a = c
H ; 16a = 2d
O: 2b = 2c + d
Let a = 1
c = 7
d = 8
b = 11
Now insert the parameters and solve;
C₇ H₁₆ + 11O₂ → 7CO₂ + 8H₂O
Answer:
True
Explanation:
Protons have a positive electrical of +1
1) We apply the ideal gas equation:
PV = nRT
n = (21300 x 3/1000) / (8.314 x 323)
n = 0.024
Your answer is correct.
2) Total pressure = Partial pressure of Hydrogen + Partial pressure of water
134.7 = 122.4 + Pw
Pw = 12.3 kPa
Your answer is correct
3) The molar fraction, volume fraction and pressure fraction of gasses are the same thing.
Thus, percentage pressure of Oxygen = 10%
Pressure of Oxygen = 2.04 x 10⁴ x 0.1
= 2.04 x 10³ kPa
Your answer is correct
Well done!
Some metalloids, such as silicon and germanium, can act as electrical conductors under the right conditions, thus they are called semiconductors<span>. Silicon, for example, appears lustrous but is not malleable or </span>ductile<span> (it is </span>brittle<span> - a characteristic of some nonmetals).</span>
It is important because they need to check each others work, this way they can get more accurate answers.
