Answer:

This might be simply as matter of convenience. It is now well known that different molecules have one of several smells. The sensation of smell is produced when the odor-causing molecule binds to certain sites (called receptors) high up in the nose.

what is the mass (in grams) of chlorine required to react with 10.0 g of sodium metal to produce sodium chloride?

Gnoma [55]

The mass of chlorine required to react with 10.0 g of sodium metal to produce sodium chloride is 15.26 g.

The balanced chemical reaction is :

2Na + Cl₂ → 2NaCl

Given data :

Mass of sodium = 10.0 g

Number of moles of Na -

Number of moles = Given mass

Molar mass

Number of moles = 10.0 g = 0.43 mol

23 g

Comparing moles of Na and Cl₂ from the balanced chemical equation,

Na : Cl₂

2 : 1

0.43 : 1 x 0.43 = 0.215 mol

Mass of chlorine gas :

(molar mass of chlorine = 71 g)

Mass of chlorine = number of moles x molar mass

Mass = 0.215 mol x 71 g/mol

= 15.26 g

ara h 6 complements ara h 2 as an important marker for ige reactivity to peanut audrey e. koid,† martin d. chapman,†

frez [133]

Purified Ara h 6 will be helpful for research into the immunological mechanisms underlying peanut allergy, including molecular and cellular studies, diagnostic IgE antibody testing, and clinical trials.

1.4% of children and 0.6% of adults in the United States suffer from the food allergy peanut. Approximately 1.8% of youngsters in the UK are allergic to peanuts. Food allergies to milk, eggs, and wheat are often outgrown by children, while allergies to peanuts are more persistent and frequently last into adulthood. As little as 0.4 g of peanut is required to cause milder allergic reactions like rashes, angioedema, and gastrointestinal problems. However, peanut is also one of the leading causes of severe, sometimes fatal anaphylactic reactions.

11. a. Amphoteric

12. a. NH₄⁺, H₂O

Explanation:

11. A substance that can act as either an acid or a base is said to be amphoteric.

Water is an amphoteric substance because it can reaction with either and acid or a base.

HCl + H₂O → Cl⁻ + H₃O⁺

NH₃ + H₂O → NH₄⁺ + OH⁻

12. What are the acids in the following equilibrium reaction?

NH₃ (aq) + H₂O (l) → NH₄⁺ (aq) +OH⁻ (aq)

H₂O water is acid 1

NH₄⁺ ammonium ion is acid 2
