which types of reactions are essentially opposites of one another?

Answers

Answer 1

Synthesis reaction and Decomposition reaction are two essentially opposite reactions to one another.

The reaction that occurs when two different atoms or molecules interact to form a different molecule or compound is known as the synthesis reaction.

For example, the formation of Sodium Chloride ([tex]NaCl[/tex]) from Sodium ([tex]Na[/tex]) and Chlorine([tex]Cl_2[/tex]). The reaction can be given by the chemical equation:

[tex]2Na+Cl_2 \rightarrow2NaCl[/tex]

The reaction that occurs when one reactant breaks down into two or more products is known as the decomposition reaction.

For example, the decomposition of Calcium Carbonate([tex]CaCO_3[/tex]) by heat into Calcium Oxide ([tex]CaO[/tex]) and Carbon Di-Oxide([tex]CO_2[/tex]). The reaction can be given by the chemical equation:

[tex]CaCO_3\rightarrow CaO+CO_2[/tex]

Hence, Synthesis reaction and Decomposition reaction are two essentially opposite reactions to one another.

Why the small community of Mount Laguna, California, just 55 miles from San Diego much colder than San Diego ?

Answers

Answer: It all boils down to the two cities' proximity to the Pacific Ocean, along with wind currents and geographical location

Explanation: It is known throughout the whole scientific community that a body of water near a city produces very stable temperatures throughout the year with small dips. When it is summer, instead of San Diego boiling in the heat, the Pacific absorbs most of this heat, making the heat in the city tolerable (almost), this makes the ocean appear cold in the summer.

When it turns to winter, the heat absorbed by the ocean in the summer gets radiated making the cold in San Diego negligible. Applying this same logic to Mount Laguna, which is not near a body of water, it can be understood that it would have more extreme temp. swings.

Along with water, there is wind currents. I don't live in Mount Laguna, but I have to assume from the context you gave me that a cold wind current usually flows there, making it colder than in San Diego, which has a warm current.

The location also matters, if this town is under a valley, canyon, or mountain it could be under a shadow further decreasing the temp. more than San Diego.

Hopefully this helps, and good luck!

The manufacturer of
a new convection oven claims that his product

How could you test this claim?

Answers

According to studies, convection ovens generally cook 25% faster than traditional ovens at a lower cooking temperature of roughly 25 degrees F, even if cooking times vary slightly between ovens.

Convection ovens, in contrast to conventional radiant (also known as thermal) ovens, include a fan that evenly distributes air inside the chamber, removing hot and cold regions.

A convection oven may cook food up to 25% more quickly than a regular oven.

Food cooks roughly 25% more quickly in a convection oven because hot air is blown directly onto it rather than merely surrounding it.

Convection ovens heat up more quickly and cook food more quickly. Thanks to some straightforward modifications to the appliance, they also cook more evenly.

All of this results in tastier baked goods, meats, and other foods.

Overall, the convection oven option is excellent if you want a crisp, rapid result, but stick with the regular oven if you want your food to retain moisture or rise before it is fully baked.

which size of micropipette would you select to deliver 215 microliters?

Answers

A micropipette of size P1000 (can read upto 1ml) would be required or selected to deliver or transfer 215 microliters of liquid.

A micropipette is an instrument used to transfer small amounts (<= 1 ml) of liquids. The scales on a micropipette are in microliters (1000µl = 1 ml). These are very delicate and expensive instruments costing between $150-300 a piece. These instruments come in three sizes which are capable of pipetting three ranges of volumes:

P20 type can transfer liquids between the range of 5- 20 µl,

P200 type can transfer liquids between the range of 20-200 µl, and

P1000 type can transfer liquids between the range of 200-1000 µl.

These instruments are used in conjunction/simultaneously with disposable and often sterile plastic tips.

A fixed volume micropipette is a pre-set instrument to measure only a specific volume. Although the volume transferred/delivered by a given pipet cannot be changed, this pipet is operated analogously to the variable micropipette. A fixed volume micropipette often does not have a tip ejector button, so the tips are to be removed manually while the required steps of the process.

It is of utmost importance to use the correct pipettor available for the volume that is to be dispensed. As going below or above the range provided for a micropipette, may damage the instrument.

Answers

From the given reaction, Oxygen serves as the limiting reagent. Methane remains after the reaction.

What is a limiting reagent?

A reactant that is completely consumed at the end of a chemical reaction is known as the limiting reagent. Since the reaction cannot proceed without this reagent, the amount of product that can be produced is constrained.

Because its quantity restricts the number of products that can be generated, the reagent that is totally consumed or reacted is known as the limiting reagent.

CO₂ + 2H₂O ⇒ CH₄+ 2O₂

One mole of methane will totally react with two moles of oxygen to produce one mole of CO₂ and two moles of water, according to the stoichiometric equation given above.

64g of oxygen and 16g of methane will totally react in such case.

When methane is burned, the weight ratio of the reactions between CH₄ and O₂ is (16:64)=1:4.

Only 32 g of oxygen are provided in the question, though. Since we only have 32 when 64 is divided, oxygen will be the limiting reagent in this scenario.

A sealed container can hold
6.28 L CO2 at 1.00 atm and 293 K.
How many moles of CO2 fill the
container?

Answers

Approximately 0.26 moles of CO2 fill the container.

To determine the number of moles of CO2 that fill the container, we can use the ideal gas law equation:

PV = nRT

Where:

P = pressure of the gas (1.00 atm)

V = volume of the gas (6.28 L)

n = number of moles of gas (unknown)

R = ideal gas constant (0.0821 L·atm/mol·K)

T = temperature of the gas in Kelvin (293 K)

Rearranging the equation, we have:

n = PV / RT

Substituting the given values:

n = (1.00 atm) * (6.28 L) / (0.0821 L·atm/mol·K) * (293 K)

Calculating the expression:

n = 6.28 / 24.0513

n ≈ 0.26 moles

Therefore, approximately 0.26 moles of CO2 fill the container.

It's worth noting that the answer is rounded to two decimal places, as the given values were provided with two decimal places. Additionally, the calculation assumes ideal gas behavior and that there are no other gases or impurities present in the container.

A sealable bag holds 3.79 L of

gas are needed to fill the bag
at 1.0 atm and 293 K?

Answers

A sealable bag holds 3.79 L of gas. To fill the bag, 0.157 moles of H2 gas are required.

Calculating the moles:

The ideal gas equation is what we use to solve this problem. Additionally known as the general gas equation. This equation is used to describe a possible ideal gas. It has a few restrictions. In 1834, Benoit Paul Emile Clapeyron made the first mention of it. An empirical form is used to write the ideal gas law:

                                 PV = n R T

where-

           P = Pressure

           V = volume

          T = Temperature

           n =  The amount of substance

           R =  Ideal gas constant

Now we have the values of these terms as-

            P = 1 atm , V = 3.79L ,  T = 293 K

and     R = 0.0826 L/atm

For getting moles of hydrogen we can use the values of variables in ideal gas equation as -

                    P V = n R T

Now              (1 atm) × ( 3.79L ) = n ×  ( 0.0826 L/atm)  × ( 293K)

                                           n = (1 × 3.79) ÷ (0.0826 x 293)

                                            =  0.157 moles

So that the 0.157moles of H₂ gas are needed for fill the bag .
