<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
Answer:
As mass increases the gravitational force increases
Explanation:
Things with mass gain a gravitational force, The bigger they are the more force, for example: the sun is the biggest so it pull us
Answer:
Final temperature = 28.0 degrees C.
Explanation:
heat absorbed = mass * specific heat * rise in temperature.
The specific heat of water is 4.186 J /g/C so we have the equation
209 = 10 * 4.186 * x where x is the temperature increase
41.86x = 209
= 5 degrees C.
That is a chemical change.. Hope I helped!
1 mol CuSO₄·5H₂O ----------- 5 mol H₂O
0,25 mol CuSO₄·5H₂O ---- Xmol H₂O
X = 5×0,25 = 1,25 mol H₂O
