Answer:
0.50 M
Explanation:
Given data
- Mass of sodium sulfate (solute): 7.1 g
- Volume of solution: 100 mL
Step 1: Calculate the moles of the solute
The molar mass of sodium sulfate is 142.04 g/mol. The moles corresponding to 7.1 grams of sodium sulfate are:
Step 2: Convert the volume of solution to liters
We will use the relation 1 L = 1000 mL.
Step 3: Calculate the molarity of the solution
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.
Answer:
That it is cooking the food or whatever you have in the pot.
Explanation:
We are learning this in science.
They define acids as proton donors, and bases as proton acceptors
If you were to have:
HNO3 + H2O -> H3O+. + NO3-
You can see that the nitric acid (HNO3) gave a hydrogen ion which has 1 proton, 0 neutrons and 0 electrons to the water so we just say that it gave a proton.
Now let's see a base
NH3 + H2O -> NH4+ + OH-
Now, you can see that the ammonia (NH3) gained a hydrogen ion (proton) from the water to become ammonium(NH4). which means it accepted a proton
That's basically it. Feel free to ask if you have any further questions
