Silver nitrate and aluminum chloride react with each other by exchanging anions: 3agno3 (aq) + alcl3 (aq) → al(no3)3 (aq) + 3agcl (s) what mass in grams of agcl is produced when 4.22 g of agno3 react with 7.73 g of alcl3?

The mass in grams of AgCl produced when 4.22 g of AgNO₃ react with 7.73 g of AlCl₃ is 3.56 g

From the question, the equation of the reaction is given as

3agno3 (aq) + alcl3 (aq) → al(no3)3 (aq) + 3agcl (s)

This can be written properly as

3AgNO₃ (aq) + AlCl₃ (aq) → Al(NO₃)₃ (aq) + 3AgCl (s)

From the balanced chemical equation above, we observe that

3 moles of AgNO₃ will react with 1 mole of AlCl₃ to yield 1 mole of Al(NO₃)₃ and 3 moles of AgCl.

To determine the mass of AgCl that would be produced when 4.22 g of AgNO₃ react with 7.73 g of AlCl₃,

First, we will convert the given masses to number of moles

Using the formula,

For AgNO₃

Mass = 4.22 g

Molar mass = 169.87 g/mol

∴

Number of moles of AgNO₃ present = 0.02484 moles

For AlCl₃

Mass = 7.73 g

Molar mass = 133.34 g/mol

∴

Number of moles of AlCl₃ present = 0.05797 moles

Since,  

3 moles of AgNO₃ react with 1 mole of AlCl₃

Then,

0.02484 moles of AgNO₃ will react with moles of AlCl₃ completely.

(NOTE: AgNO₃ is the limiting reagent and AlCl₃ is the excess reagent)

∴ Only 0.00828 moles of AlCl₃ will react.

Now, since

3 moles of AgNO₃ will react with 1 mole of AlCl₃ to yield 1 mole of Al(NO₃)₃ and 3 moles of 3AgCl

Therefore,

0.02484 moles of AgNO₃ will react with 0.00828 mole of AlCl₃ to yield 0.00828 mole of Al(NO₃)₃ and 0.02484 moles of AgCl

∴ 0.02484 moles of AgCl is produced during the reaction.

Now, we will convert this amount to grams

From the formula

Number of moles = 0.02484 moles

Molar mass = 143.32 g/mol

∴ Mass of AgCl produced = 0.02484 × 143.32

Mass of AgCl produced = 3.56 g

Hence, the mass in grams of AgCl produced when 4.22 g of AgNO₃ react with 7.73 g of AlCl₃ is 3.56 g

3.6 grams

Explanation:

According to stoichiometry:

3 mole of react with 1 mole of

0.025 moles of react with = of

Thus is the limiting reagent as it limits the formation of product and is the excess reagent.

3 moles of produce = 3 moles of

0.025 moles of produce = of

Mass of produced=

Thus 3.6 g of is produced.

answer: option (4) is the correct answer.

explanation:

areas which are at low altitudes and near the equator tend to receive direct sunlight from the sun. hence, heat energy or radiations from the sun make these areas warmer and they have warmest water.

whereas areas which are at high altitudes and away from the equator do no receive direct sunlight. hence, no direct contact from the sun makes these regions colder and thus, they have colder water.

thus, we can conclude that the statement areas at low latitudes near the equator have the warmest water because they receive the most direct sunlight best explains the relationship between an area's geography and the temperature of its surface water.
