<span>What is the total number of moles of solute in 2.0 liters of 3.0 M NaOH</span>
D) 6.0 moles
The following are heterogeneous mixture: MILK THAT IS SOLD AT THE STORE, A CAKE MIX AND MIXED NUT.
An heterogeneous mixture is one which contained many parts which can be separated out.
A smoothie is an homogeneous mixture because the juice of different fruits that are use can not be separated out.
Explanation:
1. A tissue is: a collection of nuclei / a collection of organelles / a collection of cells / a collection of organs.
2. The four major tissue types are: epithelial / fat / connective / bone / muscle / nervous / blood.
3. Epidermal tissue: protects and supports the body / covers body surfaces / is responsible for movement / lines hollow organs / transmits nerve impulses / forms glands.
4. The inside of blood vessels is lined with: cuboidal epithelium / squamous epithelium / transitional epithelium / columnar epithelium.
5. The tissue illustrated below is: cuboidal epithelium / adipose tissue / squamous epithelium / loose connective tissue / blood.
Squamous epithelium unlabelled for ws.
Answer:
Following are the <span>conjugate acid-base pairs;
1) NH</span>₃ , NH₄⁺
2) CH₃CO₂⁻ , CH₃COOH
Explanation:
According to Brønsted–Lowry acid–base theory an acid is any specie which can donate H⁺. When an acid donates proton it is converted into conjugate base.
Example:
CH₃COOH + BASE → CH₃COO⁻ + Base-H
In above reaction Acetic Acid (CH₃COOH) is acid, and after loosing proton it is converted into conjugate base i.e. Acetate (CH₃COO⁻).
And according to Brønsted–Lowry acid–base theory base is any specie which can accept H⁺. When base accepts proton it is converted into conjugate acid.
Example:
NH₃ + A-H → NH₄⁺ + A⁻
In above reaction Ammonia (NH₃) is a base, and after accepting proton it is converted into conjugate acid i.e. Ammonium (NH₄⁺)
