<h3>the balanced chemical reaction would be :</h3>
CH4 + 2O2 =》CO2 + 2H2O
Answer:
the balanced chemical reaction is provided above .
Explanation:
the given reaction is reaction of methane with oxygen ( or burning of methane in presence of oxygen )
it is highly exothermic, because high amount of heat is evolved in this reaction
The combustion of methane, CH4, releases 890.4 kJ/mol. That is, when one mole of methane is burned, 890.4 kJ are given off to the surroundings. This means that the products have 890.4 kJ less than the reactants.
Answer:
When we increase the temperature of one of the reactants in a chemical reaction, this increases the particles kinetic energy, making them move much faster than they were before. This also increases the chance of a more successful collision and the rate of reaction.
Explanation:
Your Welcome
CO2 and H2O are compounds hope this helped :)
Answer:
The answer to your question is Final volume = 58.37 ml
Explanation:
Data
density = 8.96 g/cm³
mass = 75 g
volume of water = 50 ml
Process
1.- Calculate the volume of copper
Density = mass / volume
Solve for volume
Volume = mass / density
Substitution
Volume = 75/8.96
Simplification
Volume = 8.37cm³ or 8.37 cm³
2.- Calculate the new volume of water in the graduated cylinder
Final volume = 50 + 8.37
Final volume = 58.37 ml
