Humans detect smell by inhaling air that contains odor molecules, hence, bind to receptors inside the nose, relaying messages to the brain. Most scents are composed of many odorants, for example, a chocolate is made up of hundreds of distinct odor molecules

Answer:

Atoms themselves do not have a smell. Molecules do.

Explanation:

What happens is that particular molecules bind to receptors in our nose, activating nerves, that then send signals to our brain, which we then interpret and perceive as “smells”. Different molecules bind to different receptors, which is why we can perceive a number of different smells

A silicon wafer with dimensions 15.00 cm x 15.00 cm x 0.0400 cm
Oxana [17]

The silicon wafer contains 20.96 g of silicon.

The mole of a substance is related to its mass and molar mass by the following equation:

<h3>Mole = mass / molar mass ....... (1)</h3>

Making mass the subject of the above equation, we have

<h3>Mass = mole × molar mass ..... (2)</h3>

With the above formula (i.e equation 2), we can obtain the mass of silicon in the wafer as follow:

Mole silicon = 0.746 mole

Molar mass of silicon = 28.09 g/mol

<h3>Mass of silicon =? </h3>

Mass = mole × molar mass

Mass = 0.746 × 28.09

<h3>Mass of silicon = 20.96 g</h3>

Therefore, the mass of silicon in the wafer is 20.96 g

Consider the following system at equilibrium:
alexgriva [62]

Answer:

A - Increase (R), Decrease (P), Decrease(q), Triple both (Q) and (R)

B - Increase(P), Increase(q), Decrease (R)

C - Triple (P) and reduce (q) to one third

Explanation:

<em>According to Le Chatelier principle, when a system is in equilibrium and one of the constraints that affect the rate of reaction is applied, the equilibrium will shift so as to annul the effects of the constraint.</em>

P and Q are reactants, an increase in either or both without an equally measurable increase in R (a product) will shift the equilibrium to the right. Also, any decrease in R without a corresponding decrease in either or both of P and Q will shift the equilibrium to the right. Hence, Increase(P), Increase(q), and Decrease (R) will shift the equilibrium to the right.

In the same vein, any increase in R without a corresponding increase in P and Q will shift the equilibrium to the left. The same goes for any decrease in either or both of P and Q without a counter-decrease in R will shift the equilibrium to the left. Hence, Increase (R), Decrease (P), Decrease(q), and Triple both (Q) and (R) will shift the equilibrium to the left.

Any increase or decrease in P with a commensurable decrease or increase in Q (or vice versa) with R remaining constant will create no shift in the equilibrium. Hence, Triple (P) and reduce (q) to one third will create no shift in the equilibrium.

Answer:

0.5 mole

Explanation:

C=12u

O=16u

1 mole carbon dioxide=44 grams

so 22grams = 0.5 mole
