Answer:
Sugar aka Glucose
Explanation:
Cellular respiration is reverse photosynthesis! Using that knowledge we know that plants release oxygen and glucose (sugar) which is what is needed for cellular respiration to occur!
Hope this helped! Stay safe and good luck!
Answer:
K(70°C) = 2213.376 s-1
Explanation:
balanced reaction:
- NO(g) + O3(g) → NO2(g) + O2(g)
∴ Ea = 63 KJ/mol
∴ A = 8.7 E12 s-1
∴ T = 70°C ≅ 343 K
Arrhenius eq:
∴ R = 8.314 E-3 KJ/K.mol
⇒ K(70°C) = (8.7 E12 s-1)e∧[-(63)/(8.314 E-3)(343)]
⇒ K(70°C) = (8.7 E12 s-1)*(2.5444 E-10)
⇒ K(70°C) = 2213.376 s-1
A non-sandblasted rock could be rough or smooth depending on how it was formed.
A sandblasted rock should be much smoother, since the sand blasts away any rough edges. It will, however, be slightly smaller due to losing those edges.
Explanation:
Removing B from the system
- Decreases the rate of the reaction. Backward reaction (formation of reactants) is favoured.
Crushing A into a powder
- Increases the rate of reaction. This is because of the increased surface area of A.
Warming the system
- Increases the rate of the reaction. Temperature is proportional to rate of reaction.
Adding more A to the system
- Increases the rate of reaction. Forward reaction (formation of products) is favoured.
Putting the system into an ice bath
- Decreases the rate of reaction. Temperature is proportional to rate of reaction.
Decreasing the pressure of the system
- Decreases the rate of the reaction.
