If an object is travelling 25.0 meters/second, how far will it travel in 45 minutes?

Answers

Speed=25m/sTime=45min=(45×60)s=2700s

[tex]\\ \rm\longmapsto Distance=Speed(Time)[/tex]

[tex]\\ \rm\longmapsto Distance=25(2700)[/tex]

[tex]\\ \rm\longmapsto Distance=67500m[/tex]

The object travelling at 25 m/s, will travel a distance of 67500 m in 45 mins.

We'll begin by converting 45 mins to seconds. This can be obtained as follow:

1 min = 60 s

Therefore,

45 mins = 45 × 60

45 mins = 2700 s

Finally, we shall determine the distance travelled by the object in 2700 s (i.e 45 mins). This can be obtained as follow:

Time = 2700

Speed = 25 m/s

Distance =?

Distance = speed × time

Distance = 25 × 2700

Distance = 67500 m

Therefore, the object will cover a distance of 67500 m in 2700 s (i.e 45 mins)

The total pressure (in atm) in the container is _____ atm.

1 point

Answers

Answer:

2.03 atm

Explanation:

Number of moles of He = 1g/4g/mol = 0.25 moles

Number of moles of F2 = 14.0g/38 g/mol = 0.37 moles

Number of moles of Ar=19.0g/40g/mol = 0.48 moles

Total number of moles = 0.25 + 0.37 + 0.48 = 1.1 moles

From;

PV=nRT

P= pressure of the gas mixture

V= volume of the gas mixture

n= total number of moles of the gas mixture

R= gas constant

T= temperature of the gas mixture

P= nRT/V

P= 1.1 × 0.082 × 293/13

P= 2.03 atm

Determine the mass of 6.33 mol of iron(II) nitrate.

Answers

Answer:

1822.72 g

Explanation:

Applying,

n = R.M/M.M.................. Equation 1

Where n = number of moles of iron(II) nitrate, R.M = Reacting mass of iron(II) nitrate, M.M = molar mass of Iron(II) nitrate.

Make R.M the subject of the equation

R.M = n×M.M............. Equation 2

From the question,

Given: n = 6.33 mol

Constant: M.M of iron(II) nitrate = 287.95 g/mol

Substitute these values into equation 2

R.M = 6.33(287.95)

R.M = 1822.72 g

Hence the mass of iron(II) nitrate is 1822.72 g

What is the mass percent of a sodium fluoride solution prepared by dissolving 0.64 moles of sodium fluoride into 63.5 grams of water?

Answers

The answer is 29.7% view on how to solve

The mass percent of a sodium fluoride solution prepared by dissolving 0.64 moles of sodium fluoride into 63.5 grams of water is 29.7%.

What is mass percent ?

Mass percent is a means to describe a component in a specific combination or to convey a concentration. The mass percentage used to describe the solution composition indicates the mass of solute contained in a given mass of solution.

To determine the mass percent of an element in a compound, we divide the mass of the element in one mole of the compound by the compound's molar mass and multiply the result by 100.

Given:

Number of moles = 0.64 moles

Moles of sodium fluoride = Given mass/molar mass

0.64 moles = Mass / 42

Mass = 26.88gram

Mass % = Mass of solute/ mass of solution × 100

= 26.88/90.48 × 100

= 29.7 %

Thus, 29.7 % is the mass percent of a sodium fluoride solution prepared by dissolving 0.64 moles of sodium fluoride into 63.5 grams of water

What is the purpose of a catalyst in the production of hydrogen?
Select the correct answer.
- to increase the rate at which water molecules decompose
- to decrease the amount of oxygen produced
- to decrease the temperature of the reaction
- to increase the activation energy of the reaction

Answers

The purpose of a catalyst in the production of hydrogen is to increase the rate at which water molecules decompose.

What is a catalyst-A catalyst is a substance that increases the rate of a chemical reaction without itself being consumed or produced during the reaction. As a result, catalysts assist in speeding up chemical reactions while also decreasing the amount of energy needed for the reaction to occur. In hydrogen production, catalysts are used to speed up the decomposition of water into hydrogen and oxygen. The use of catalysts lowers the activation energy required for the reaction to occur, resulting in a faster reaction rate and lower operating temperatures.What is the process of hydrogen production?Hydrogen production has various methods, and one of the most commonly used methods is water electrolysis. In this method, water molecules are split into hydrogen and oxygen using an electric current passed through an electrode. Water is broken down into hydrogen and oxygen during the process, with the assistance of a catalyst. During this process, a catalyst like platinum or nickel is employed to speed up the chemical reaction of water decomposition.

When an electric current is applied to the catalyst, water molecules are broken apart, releasing hydrogen and oxygen atoms.Catalysts lower the activation energy of the reaction, allowing it to occur faster than it would otherwise. In hydrogen production, catalysts are crucial since they enable the reaction to occur at a lower temperature, reducing energy consumption and minimizing operating costs. As a result, the use of catalysts is essential to the production of hydrogen.

You work in the special effects department of a movie studio. You are currently working on a superhero movie where the hero is very strong and cannot be hurt by normal weapons such as a sword. In the next scene, the villain is going to hit the hero with a lead pipe. The hero's costume is mostly made of foam and carbon so that is it very light and easy to move around in but will crumble if hit with anything hard. For this scene, a section of the costume needs to be replaced with a different material that will only dent, not crumble, when hit with the pipe. You are on a deadline and look around the props department for ideas, what could you use?

Answers

Answer:

Aluminum or Galvanized iron

Explanation:

If the costume has to be such that the hero does not get hurt when hit by a lead rod and also is easy for the mobility then the suitable option for the costume could be Aluminum material which will only dent and not crumble.

Galvanized iron could be another choice being harder and stronger as compared to aluminum but a little heavy. It can sustain heavy impacts as compared to aluminum.

What is the pressure in atm exerted by 1.8 g of H2 gas exert in a 4.3 L balloon at 27ºC? R = 0.821(L*atm) / (mol*K)

The pressure in atm exerted by 1.8 g of H₂ gas exert in a 4.3 L balloon at 27ºC is 5.12 atm

What is Ideal gas law ?

The ideal gas law (PV = nRT) relates the macroscopic properties of ideal gases. An ideal gas is a gas in which the particles (a) do not attract or repel one another and (b) take up no space (have no volume).

Let's convert grams to moles (via molar mass).

Molar Mass (H₂) :  2 (1.008 g/mol)

Molar Mass (H₂) :  2.016 g/mol

1.8 grams H₂               1 mole

----------------------  x  ----------------------  =  0.893 moles H₂

                                2.016 grams

The Ideal Gas Law equation looks like this:

PV = nRT

In this equation,

P = pressure (atm) V = volume (L) n = moles R = Ideal Gas Constant (0.0821 L*atm/mol*K)T = temperature (K)

After converting Celsius to Kelvin, you can put the given values into the equation and simplify to find the pressure.

P = ? atm                                R = 0.0821 L*atm/mol*K

V = 4.3 L                               T = 27 °C + 273.15 = 300.15 K

n = 0.893 moles

PV = nRT

P (4.3 L) = (0.893 moles) (0.0821 L*atm/mol*K)( 300.15 K)

P (4.3 L) =  22.0021

P = 5.12 atm

Therefore, The pressure in atm exerted by 1.8 g of H₂ gas exert in a 4.3 L balloon at 27ºC is 5.12 atm
