A train with an initial velocity of 31 m/s begins accelerating at rate of 0.0705 m/s^2. If the train travels for 180.5s, how far does it travel?

Answers

Answer 1

Answer:

v = 43.72 m/s

Explanation:

Given that,

Initial velocity of the train, u = 31 m/s

Acceleration of the train, a = 0.0705 m/s²

Time for which the train travel, t = 180.5 s

We need to find the final velocity of the train. Let it is v.. Using first equation of kinematics to find it such that,

[tex]v=u+at\\\\v=31+0.0705\times 180.5\\\\v=43.72\ m/s[/tex]

So the final speed of the train is equal to 43.72m/s.

El mercurio ha sido utilizado como elemento para medir la temperatura porque Es una mezcla. Al aumentar la temperatura se dilata con facilidad. Es un buen conductor del calor. Es un buen conductor de la electricidad.

Answers

Answer:

La respuesta correcta es: Al aumentar la temperatura se dilata con facilidad

Explanation:

El mercurio (Hg) es un elemento metálico que a temperatura ambiente es un líquido. Tiene la propiedad de dilatarse con facilidad al aumentar la temperatura, propiedad que ha sido utilizada en los termómetros de mercurio. En estos termómetros, el mercurio está dentro de un tubo de vidrio graduado con un bulbo para transmitir el calor. Al estar en contacto con un cuerpo más caliente (a mayor temperatura), el mercurio del interior del termómetro se dilata (expande su volumen) y asciende por el tubo indicando la temperatura correspondiente, graduada en el vidrio.

Answers

Answer:

c) 7.2 moles

Explanation:

7.2 moles of [tex]CO_2[/tex]  are produced during the complete combustion of 3.6 moles of [tex]C_2H_6[/tex].  Hence, option C is correct.

What are moles?

A mole is defined as 6.02214076 ×[tex]10^{23}[/tex]

of some chemical unit, be it atoms, molecules, ions, or others. The mole is a convenient unit to use because of the great number of atoms, molecules, or others in any substance.

Balance your chemical reaction first.

[tex]2C_2H_6 + 7O_2[/tex] —> [tex]4CO_2 + 6H_2O[/tex]

2 moles of [tex]C_2H_6[/tex] produce 4 moles of [tex]CO_2[/tex].

So, 3.6  moles of [tex]C_2H_6[/tex]  produce= (4÷2)x3.6 =7.2 moles

Hence, 7.2 moles of [tex]CO_2[/tex]  are produced during the complete combustion of 3.6 moles of [tex]C_2H_6[/tex].

Calculate the volume of 150kg of chlorine gas at room temperature and pressure. The volume of one mole of gas at room temperature and pressure is 24.0dm^3. Relative formula mass (Mr): Cl2=71​

Answers

Answer:

Given mass 150 kg= 150000 gram

molar mass 71 gram

number of moles = given mass/molar mass

= 2112.76 moles

1 mole = 24 Dm³

2112.76 mole =24×2112.76= 50706.24 Dm³

The volume of the mole of gas at room temperature and pressure is 50,704.08dm³

We need to first calculate the number of moles of Chlorine gas (Cl₂)

Number of moles = Mass/Molar mass

Given the following parameters

The molar mass of Cl₂ = 71g/mol

Mass of chlorine gas = 150kg = 150,000g

Get the number of moles

[tex]n=\frac{150,000}{71}\\n=2,112.67moles\\[/tex]

Given that volume of 1 mole at STP = 24.0dm³

2112.67 moles = x

Get the volume of the chlorine gas at STP.

Volume of Cl₂ at STP = 24 × 2112.67

Volume of Cl₂ at STP = 50,704.08dm³

Hence the volume of the mole of gas at room temperature and pressure is 50,704.08dm³

Molarity = moles of solute/volume (in liters) of solution.

We have 14.1 moles of FeCl3, which is the solute, and the volume of our solution is 2.350 liters. So, the molarity of the solution would be (14.1 moles FeCl3)/(2.350 L solution) = 6 moles/L FeCl3 or 6 M FeCl3.

how many moles of water is 5.02 x 10 18 molecules of water

Answers

Answer:

8.334×10^-6 moles

Explanation:

a mole is 6.023×10^23

5.02×10^18 ÷ 6.023×10^23=8.33×10^-6

so there are 8.33×10^-6 moles of water in 5.02x10^18 molecules of water

The number of moles of water in which 5.02 × 10¹⁸ molecules of water is present is 8.33 × 10⁻⁶.

What is moles?

Moles is a unit which is used to tells about the quantity of any substance, in one moles of any substance 6.023 × 10²³ number of atoms of that substances are present.

In 1 mole of water = 6.023 × 10²³ number of molecules of water is present

So, number of 5.02 × 10¹⁸ molecules of water present in how many moles will be calculated as:
Required moles = 5.02 × 10¹⁸ / 6.023 × 10²³ = 8.33 × 10⁻⁶

Hence, required moles is 8.33 × 10⁻⁶.

Describe the difference between a flask, beaker, and graduated cylinder.
How does the purpose of each differ?

Answers

Answer:

Both graduated cylinders and beakers are pieces of laboratory glassware that have a specific function. Graduated cylinders typically are more accurate at reading the volumes of the liquid inside. Beakers are better for stirring and mixing liquids.

Flasks are notable for their unique shape: a rounded vessel and a cylindrical neck. The main differing characteristic between a flask and a beaker is that beakers have straight sides, rather than slanted sides like a flask. Beakers are mainly for measuring and transporting liquids from one site to the next.

What is the mass in grams of the following measurements? 1.00 mol Al ___________ 6.02 x 10 23atoms Al ___________

Answers

Answer:

Mass of 1 mole of Aluminium = Mass of 6.02 x 10 23atoms of Aluminium =  26.98 grams.

Explanation:

1 mole of any element or molecule has 6.02 x 10 23atoms or subparts.

Hence 1 mole of aluminum will also have 6.02 x 10 23atoms. Hence, it is clear that mass of 1 mole of Aluminium will be equal to 6.02 x 10 23atoms of Aluminium.

Thus,

Mass of 1 mole of Aluminium = Mass of 6.02 x 10 23atoms of Aluminium =  26.98 grams.

Answers

Answer:

2.7 mL

Explanation:

The equation of the reaction is;

2AlBr3 + 3Cl2 -----> 2AlCl3 + 3Br2

Number of moles in 2.12 x 1022 formula units of aluminum bromide

1 mole of AlBr3 = 6.02 * 10^23 formula units

x moles = 2.12 x 1022 formula units

x = 2.12 x 1022 formula units  * 1 mole/ 6.02 * 10^23 formula units

x = 0.0352 moles of AlBr3

According to the reaction equation;

2 moles of AlBr3 produces 3 moles of Br2

0.0352 moles of AlBr3 produces 0.0352 moles  *  3 moles /2 moles

= 0.0528 moles of Br2

Mass of Br2 produced = 0.0528 moles of Br2 * 159.808 g/mol

Mass of Br2 produced = 8.44g

But density = mass/volume

volume = mass/density

volume of Br2 = 8.44 g/ 3.12 g/mL

volume of Br2 =  2.7 mL
