Answer: Mixtures you can separate are like cereal and milk. Hope that helps
Explanation: Filteration is required to separate a mixture.
So heterogeneous mixures (that contain substances with different particle sizes) can be separated with a filter.
Homogeneous mixtures are uniform in composition so they will not be able to be separated.
Answer:
1.05 mol
Explanation:
Step 1: Given data
- Molarity of sulfuric acid (M): 1.325 M (1.325 mol/L)
- Volume of solution (V): 395 mL (0.395 L)
Step 2: Calculate the moles of sulfuric acid (n)
We will use the following expression.
M = n/V
n = M × V
n = 1.325 mol/L × 0.395 L = 0.523 mol
Step 3: Calculate the moles of H⁺
H₂SO₄ dissociates completely according to the following equation.
H₂SO₄ ⇒ 2 H⁺ + SO₄²⁻
The molar ratio of H₂SO₄ to H⁺ is 1:2. The moles of H⁺ are 2/1 × 0.523 mol = 1.05 mol.
Answer:
I don't know any except helium, sorry I couldn't do much.
Answer:
The correct answer is A defective gene is replaced with a normal gene.
Explanation:
Gene therapy is an alternative therapy for the treatment of some diseases.
Although this therapy is still in development, and carries many risks, it is expected to have very good results in the coming years.
In such therapy the following happens:
- a defective gene is replaced with a normal gene.
- the introduced gene matches the defective one or produces a beneficial protein.
- faulty genes are disabled.
Given this information we can say that the correct answer is A defective gene is replaced with a normal gene
