Answer:

250 Newtons.

Explanation:

Weight is a force and the Second Law of Newton can be used to figure out the Force ( weight) of this mass. Since F = ma, and 'a' on Earth is the acceleration due to freefall at 10 m/s^2 ( really 9.8 m/s^2- so your teacher may want your answer as 245 N), you multiply your mass ( 25g ) and your acceleration on Earth and you get 250 N.

Based on Google Trends, the search term “turkey” is most popular in the states of Tennessee, Pennsylvania, and New Hampshire, with Indiana and Vermont rounding up the top 5.

Californians consume the most turkey per capita of any state, while not being one of the top five. It's Missouri. It comes in at five. Minnesota is the state that produces the most turkeys, followed by North Carolina, Arkansas, and Virginia.

Turkey, or the Republic of Turkey, is a transcontinental nation with the majority of its territory in Western Asia's Anatolia Peninsula and a tiny section in Southeast Europe's Balkan Peninsula.

The official name of Turkey is now Türkiye. The United Nations has officially accepted the adjustment requested by the Turkish government that the nation be referred to by its Turkish name.

Turkey is well-known for a variety of both oriental and European aspects, including the magnificent Hagia Sophia and traditional Turkish tea. Additionally, well-known are its carpets, hammams, bazaars, travel hotspots like Cappadocia and Istanbul, and sweets like baklava and Turkish delight.

Thus,  Minnesota is the state that produces the most turkeys, followed by North Carolina, Arkansas, and Virginia.

Answer:

V = 34.3 L

Explanation:

Given data:

Volume of hydrogen produced = ?

Mass of magnesium = 36.7 g

Temperature and pressure = standard

Solution:

Mg + 2HCl       →   MgCl₂ + H₂

Number of moles of magnesium:

Number of moles = mass/molar mass

Number of moles = 36.7 g/ 24 g/mol

Number of moles = 1.53 mol

Now we will compare the moles of magnesium with hydrogen.

                         Mg           :          H₂

                          1              :           1

                         1.53          :          1.53

Number of moles of hydrogen produced = 1.53 mol

Volume of hydrogen:

PV = nRT

V = nRT / P

V = 1.53 mol × 0.0821 atm.L/mol.K × 273 K/ 1 atm

V = 34.3 L

The following statement which is NOT true about the lens is:

The lens is a piece of glass which  is used for the dispersal or refraction of light and is used to focus light onto the retina of the eye.

As a result of this, the lens is responsible for refracting of light, focusing of light and it is transparent. However, it does not send light to the optic nerve.

Explanation:afa

Answer:

The relationships between molar mass and density for a monoatomic gas can be easy.  

The Ideal Gas Law, PV = nRT can be arranged so that n moles equals the mass/molar mass of the gas to become,

PV =  

M

mRT

​  

where m is the mass and M is the molar mass.

M =  

PV

mRT

​  

, if you hold the temperature of the gas constant the equation reduces to the Boyle's law or  

PV

m

​  

The mass will be constant assuming the container is closed and so the gas cannot be escaped so, PV will be constant.  

D =  

V

m

 and M =

M =

The higher the density of the gas the higher the molar mass and vice versa.

Two-electron.

Explanation:

Hello!

In this case, since the half-reaction by which chlorine is reduced to aqueous chloride ion is:

[tex]Cl^0_2\rightarrow 2Cl^-[/tex]

We can see each chlorine undergo a decrease of electrons by 1, it means that, since there are two chlorine atoms undergoing an electron decrease, we write:

[tex]Cl^0_2+2e^-\rightarrow 2Cl^-[/tex]

Which means this is a two-electron process.

Answer:

Mass of compound c = 6 g

Explanation:

Given:

Mass of compound a = 2.5 g

Mass of compound b = 3.5 g

Find:

Mass of compound c

Computation:

According to Law of conservation of mass

Mass of compound a + Mass of compound b = Mass of compound c

Mass of compound c = 2.5 + 3.5

Mass of compound c = 6 g

Answer:

E. Cool a solvent below room temperature

Explanation:

When a solution that has had more solute dissolved at a higher temperature is now cooled, it becomes supersaturated at the lower temperature. Because that supersaturated solution holds more solute than is stable at the lower temperature, crystals start to form.

To solve this we must be knowing each and every concept related to  supersaturated solution. Therefore, the correct option is option E among all the given options.

The excess solute solution that the solvent can dissolve is known as a supersaturated solution. The substance that may dissolve in a solution, such as salts but not limited to salts, is referred to as a solution if we are unsure of what a solute or solvent is.

A solution becomes supersaturated at a lower temperature when it is cooled after having additional solute incorporated at a higher temperature. Crystals begin to form because the supersaturated solution contains more solute than would be stable just at lower temperature.

Therefore, the correct option is option E among all the given options.

1.2029 J/g.°C

Explanation:

Given data:

Specific heat capacity of titanium = 0.523 J/g.°C

Specific heat capacity of 2.3 gram of titanium = ?

Solution:

Specific heat capacity:

It is the amount of heat required to raise the temperature of one gram of substance by one degree.

Formula:

Q = m.c. ΔT

Q = amount of heat absorbed or released

m = mass of given substance

c = specific heat capacity of substance

ΔT = change in temperature

1 g of titanium have 0.523 J/g.°C specific heat capacity

2.3  × 0.523 J/g.°C

1.2029 J/g.°C

Answer: 106.19%

Explanation:

percent yield = actual/theo * 100%

our theoretical yield is the limiting reagent and then we have our actual given

.1030/.0970* 100% = 106.19%

The percent yield of prepared aspirin is 102.84%.

Percent yield is defined as the ratio of actual yield to the theoretical yield  multiplied by 100. If the actual and theoretical yield are same then the percent yield is 100%.If actual yield is less than the theoretical yield then the percent  yield is less than 100%.Reason of this condition arising is the incompletion of reaction  or loss of sample during recovery process.

In cases where percent yield is over 100% it indicates that more sample is recovered than the predicted amount.This condition arises when there are other simultaneous reactions taking place leading to the formation of product. It can also arise if there is incomplete removal of impurities from the sample .

By using the formula of percent yield , yield of aspirin is calculated as,

0.1030/0.1264 ×100=81.48%.

Thus, the percent yield of aspirin is 81.48%.
