Answer:

Option (B)

Explanation:

<u>According to the demand law, the price of any product is inversely proportional to the demand for that product</u>. This means that if the rate of any product increases, then the demand decreases. And if the rate of the product decreases then demand simultaneously increases.

in the given condition, <u>the price of the peaches if increases, then the demand will decrease. As a result of which a lesser amount of peaches will be sold</u>.

Hence, the correct answer is option (B)

Depending on the numbers on the side for the price, it could be A or B; if the numbers go from higher to lower then its A, if it goes from lower to higher then its B

antiseptic1488 [7]

Mass of Aluminum (in g) : 4.104

<h3>Further explanation</h3>

Reaction

2 Al(s) + 6 HCl(aq) → 2 AICI₃ (aq) + 3 H₂(g)

mol HCl :

$\tt 1.3\times 0.35=0.455$

mol Al :

A sample of carbon-12 has a mass of 6.00 g. How many atoms of carbon-12 are in the sample?

Serjik [45]

<em>mC: 12g/mol</em>

12g ------- 6,02·10²³ a.
6g --------- X
X = (6×<span>6,02·10²³)/12
</span><u>X = 3,01·10²³ atoms</u>

How many grams of barium chloride are produced when 1.25 x 1023 molecules of HCl reacts with barium?

sp2606 [1]

Considering the reaction stoichiometry and Avogadro's Number, the mass of barium chloride produced is 21.6 grams.

<h2>Balanced reaction</h2>

The balanced reaction is

2 HCl + Ba → BaCl₂ + H₂

<h2>Moles of HCl that react</h2>

Avogadro's Number is called the number of particles that make up a substance (usually atoms or molecules) and that can be found in the amount of one mole of said substance. Its value is 6.023×10²³ particles per mole. Avogadro's number applies to any substance.

Then you can apply the following rule of three: if 6.023×10²³ molecules are contained in 1 mole of HCl, then 1.25×10²³ molecules are contained in how many moles of HCl?

amount of moles of HCl= (1.25×10²³ molecules × 1 mole)÷ 6.023×10²³ atoms

<u><em>amount of moles of HCl= 0.2075 moles</em></u>

Then, 0.2075 moles of HCl react.

<h2>Reaction stoichiometry</h2>

By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of moles of each compound participate in the reaction:

HCl: 2 moles
Ba: 1 mole
BaCl₂: 1 mole
H₂: 1 mole

<h2>Mass of barium chloride produced</h2>

Then you can apply the following rule of three: if by stoichiometry 2 moles of HCl produce 1 mole of BaCl₂, 0.2075 moles of HCl will produce how many moles of BaCl₂?

$amount of moles of BaCl_{2} =\frac{0.2075 moles of HCl x 1 mole of BaCl_{2} }{ 2moles of HCl}$

<u><em>amount of moles of BaCl₂= 0.10375 moles</em></u>

Being the molar mass of BaCl₂ 208.24 g/mole, then the mass of barium chloride produced is calculated as:

$0.10375 molesx\frac{208.24 grams}{1 mole} =21.6 grams$

Finally, the mass of barium chloride produced is 21.6 grams.
