Velocity decreases across a rough surface due to friction; vice-versa, on a slippery surface (a smooth surface, or one lubricated by oil or soap), the friction decreases, which in turn increases the velocity.
Answer:
CuO+2HCl>h2o+CuCl2
fe203+6hcl->2fecl3+3h2O
gọi CuO, fe2o3 lần lượt là x,y
80x+160y=10
2x+6y=0.35
giải phương trình ta dc hai số x,y(tính phương trình kia ra)
cuo ban đầu sẽ là :60*x=z
fe203 ban đầu sẽ là :10-z=

Answer:
The unbalanced chemical equation of propane combustion is
C₃H₈ (g) + O₂ (g) → CO₂(g) + H₂O(g)
Explanation:
Combustion is a type of chemical reaction in which there is the release of energy in the form of heat. This means that this reaction can be called exothermic.
When propane reacts with oxygen present in the air, it releases a high amount of heat. If the reaction is fully completed, the products are carbon dioxide and water vapor.
