Answer:

8.68 L is the new volume

Explanation:

You use Boyle's law for this.

[tex]P_{1}V_{1}=P_{2}V_{2}[/tex]

[tex]P_{1}[/tex] = first pressure

[tex]P_{2}[/tex] = second pressure

[tex]V_{1}[/tex] = first volume

[tex]V_{2}[/tex] = second volume

Convert pressure from atm to mmHg (use same units):

5.97 x 760 = 4537.2 -> 4.54 x 10³

...maintain 3 significant figures in calculation, and round as needed...

(4.54 x 10³ mmHg)(2.79 L) = (1460 mmHg)([tex]V_{2}[/tex])

(4.54 x 10³ mmHg)(2.79 L) / (1460 mmHg) = [tex]V_{2}[/tex] = 8.68 L

Hope this helps :)

Solution :

Molecular mass of NaOH is 23 g/mol .

So, number of moles of NaOH is given by :

[tex]n = \dfrac{10}{40}\ mole[/tex]

Now, we know molarity is given by :

[tex]Molarity = \dfrac{Number \ of \ moles\ of \ salute}{Volume ( in \ Liter ) }[/tex]

[tex]M = \dfrac{10}{40\times 2.4} \ M\\\\M = 0.104 \ M[/tex]

Hence, this is the required solution.

Answer: The answer is A O0.104 M NaOH

Have GM crops caused damage to the environment? Crops do not damage the environment simply because they are GM. Some farming practices, such as the overuse of herbicides resulting in the excessive eradication of wild plants from farmland have been shown to harm the environment.

Some benefits of genetic engineering in agriculture are increased crop yields, reduced costs for food or drug production, reduced need for pesticides, enhanced nutrient composition and food quality, resistance to pests and disease, greater food security, and medical benefits to the world's growing population.

Answer:

Yes

Explanation:

Food that comes from the engineering food factories wrapped in plastic which can be dangerous for the environment.

Answer:

A.  like poles of magnets repel each other

B. Unlike poles of magnets attract each other.

C. The magnet's force is stronger than the earth's at this distance

Explanation:

From the diagram given, we can take the portion of the compass painted red to be the north, and the porion painted white to be the south.

In the first diagram, the north of the compass gets attracted to the south of the compass showing, that unlike poles attract each other and like poles repel each other.

In the second diagram, the south of the compass needle gets attracted to the north of the magnet showing, that like poles repel each other, and unlike poles attract each other.

The mere fact that the compass needle is not pointing towards the north shows that it is being affected by the magnet placed beside it. Normally every compass held under the influence of the magnetic pull of the earth points north. But since this is not the case here, we can say that  The magnet's force is stronger than the earth's at this distance

Answer:

114.8g PbI2 are produced

Explanation:

To solve this question we must convert the mass of KI to moles using its molar mass (KI = 166.0g/mol). As 2 moles of KI produce 1 mole of PbI2 we can find its moles and its mass (Molar mass PbI2: 461.01g/mol) as follows:

Moles KI:

82.7g KI * (1mol / 166.0g) = 0.498 moles KI

Moles PbI2:

0.498 moles KI * (1mol PbI2 / 2mol KI) = 0.249 moles PbI2

Mass PbI2:

0.249moles * (461.01g/mol) =

Answer:

H^+(aq) + OH^-(aq) ------->H2O(l)

Explanation:

Neutralization is a reaction that occurs between an acid and a base to yield salt and water only.

The net ionic equation shows the species that are directly involved in a reaction. It eliminates the spectator ions.

Recall that a strong acid and a strong base ionizes completely in solution to yield hydrogen and hydroxide ions respectively.

The net ionic equation for the neutralization of a strong acid and a strong base is; H^+(aq) + OH^-(aq) ------->H2O(l)

Answer:

The eruption of Mount Tambora eventually reduced the average global temperature by as much as 3 °C.

Explanation:

The Mount Tambora eruption was the largest and most destructive volcanic event in recorded history, expelling as much as 150 cubic km (roughly 36 cubic miles) of ash, pumice, and other rock, and aerosols—including an estimated 60 megatons of sulfur—into the atmosphere. As that material mixed with atmospheric gases, it prevented substantial amounts of sunlight from reaching Earth’s surface, eventually reducing the average global temperature by as much as 3 °C.

Sodium hydroxide, also known as lye and caustic soda, is an inorganic compound with the formula NaOH. It is a white solid ionic compound consisting of sodium cations Na + and hydroxide anions OH −

The answer is Cl.

Group/family 18, the Nobel Gases, have full octets of 8 valence electrons. Each time you move to the LEFT one time within the nonmetals on the Periodic Table, an electron is lost. So, any element in group/family 17 would have 7 valence electrons (you can check this by drawing Bohr diagrams for each element within group/family 17).

So, we now know that the element is a nonmetal found in group/family 17. Therefore, it is found in the "p" block. For elements found in the "p" block, periods represent energy levels. 

Answer:

Naturely, the direction of the heat flow is from zone of high temperature to zones of low temperature. Hence, the direction of heat flow is from the sample of unknown metal and surrounding water until thermal equilibrium in the water-sample system is reached.

Radio waves, ultraviolet rays, X-rays, and gamma rays are all examples of electromagnetic radiation, as are microwaves.

There are several uses for microwaves, including for communications, radar, and—possibly for the most part—cooking. Waves or particles of electromagnetic radiation with various wavelengths and frequencies are communicated.

The electromagnetic spectrum (EM spectrum) is the name given to this wide spread of frequencies. In general, the spectrum is divided into seven areas in ascending sequence of increasing energy and frequency and decreasing wavelength.

Radio waves, microwaves, infrared (IR), visible light, ultraviolet (UV), X-rays, and gamma-rays are some of the common names for these types of energy. In the electromagnetic (EM) spectrum, microwaves are found between radio and infrared light.

Therefore, Radio waves, ultraviolet rays, X-rays, and gamma rays are all examples of electromagnetic radiation, as are microwaves.

Answer:

C. H2O is the base and H3O+ is the conjugate acid

Explanation:

According to Bronsted-Lowry acid-base theory, an acid is a substance that loses an hydrogen ion or proton (H+) while a base is a substance that gains an hydrogen ion (H+) or proton. Furthermore, this theory states that, the molecule formed when an acid donates its proton is called the CONJUGATE BASE, while the molecule formed when the base accepts proton is called CONJUGATE ACID.

In this question, the following equation is given:

NH4+(aq) + H2O(aq) ⇌NH3(aq) + H3O+ (aq)

Water (H2O) is the base in this equation because according to Bronsted-Lowry acid-base theory, it accepts an hydrogen ion (H+) while hydroxonium ion (H3O+) is the conjugate acid.
