<h3>Answer:</h3>
2 C₃H₈O + 9 O₂ → 6 CO₂ + 8 H₂O
<h3>Explanation:</h3>
This is the combustion reaction in which Isopropanol, an organic compound is burnt in the presence of Oxygen to produce Carbon dioxide and water vapors.
The General reaction is as,
Isopropanol + Oxygen → Carbon dioxide + Water
Chemical formulae of above compounds and molecule are,
Isopropanol = C₃H₈O
Oxygen = O₂
Carbon Dioxide = CO₂
Water = H₂O
Hence, the balance chemical equation can be written as,
2 C₃H₈O + 9 O₂ → 6 CO₂ + 8 H₂O
Atomic mass Si = 28.0855 u.m.a
28.0855 g -------------------- 6.02x10²³ atoms
3.96x10³ g ------------------- ?? atoms
( 3.96x10³) x 6.02x10²³ / 28.0855 =
8.48x10²⁵ atoms
Answer:
B. 1.82(10³) seconds (1820 seconds)
Explanation:
Speed of Light: 3.00(10⁸) m/s or 3.00(10⁵) km/s
We know the distance from the Moon to Earth as 5.46(10⁸) km
We simply divide the distance by the speed of light:

We should get 1820 seconds or B. 1.82(10³) as our answer.
