Moles Cu+2 = M * V
= 0.05 L * 0.011 m
= 0.00055 moles
when the molar ratio of Cu2+: EDTA = 1:1 so moles od EDTa also =0.00055 moles
and when the Molarity of EDTa = 0.0630 M
∴ Volume of EDTA = moles / Molarity
= 0.00055 / 0.0630
= 0.0087 L = 8.7 L
The relative molecular mass of acid A : 50 g/mol
<h3>Further explanation</h3>
Given
40.0 cm³(40 ml) of 0.2M sodium hydroxide
0.2g of a dibasic acid
Required
the relative molecular mass of acid A
Solution
Titration formula
M₁V₁n₁=M₂V₂n₂
n=acid/base valence(number of H⁺/OH⁻)
NaOH ⇒ n = 1
Dibasic acid = diprotic acid (such as H₂SO₄)⇒ n = 2
mol = M x V
Input the value in the formula :(1 = NaOH, 2=dibasic acid)
0.2 x 40 x 1 = M₂ x V₂ x 2
M₂ x V₂ = 4 mlmol = 4.10⁻³ mol ⇒ mol of Acid A
The relative molecular mass of acid A (M) :
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:
The answer to that question would be A
