Answer:
9g
Explanation:
moles O2 = mass / Mr = 12 / 2(16.0) = 0.375
ratio O2 : NO = 5:4
moles NO produced = 0.375 * 4/5 = 0.3
mass NO = Mr * mol = (14.0+16.0) * 0.3 = 9g
Answer:
Option 1, Cl is reduced and gains electrons
Explanation:
HClO₃ → HClO₂
In HClO₃, chlorine acts with +5 in the oxidation state
In HClO₂,, chlorine acts with +3 in the oxidation state.
The state has been reducted, so the Cl has been reduced. As it was reduced, it means that has won e⁻, in this case 2
Cl⁻⁵ → Cl⁻³ + 2e⁻
Answer is: <span>the pH value(level) is the independent variable.</span><span>
</span>
Missing question: <span>We conducted an experiment where we added 0.5 g of lactose to 5 different test tubes all containing 5 different pH levels. What is the independent variable?
In this experiment pH level changes, so results depend on different pH values.
Mass of lactose is same during experiment,so t</span>he number of molecules of product formed per minute is the <span>dependent variable.</span>
Answer:
A. Herbivores have longer digestive systems than carnivores have.
Explanation:
We can conclude that the herbivores have longer digestive systems compared to carnivores.
Carnivores feeds on other animals whereas herbivores eats plants.
- Most herbivores have a four stomach compartment system that helps them process and digest their food.
- This is because they have to process cellulose in plants which needs to be properly broken down.
- Flesh eating carnivores do not require this arrangement.
- The four stomach compartment of most herbivores includes Rumen, Reticulum, omasum and abomasum.
- They also chew the cud whereby they regurgitate food materials.
