Answer:

[tex]Distance = 40km[/tex]

Explanation:

Given

[tex]Speed = 80km/hr[/tex]

[tex]Time = 0.5hr[/tex]

Required

Determine the distance covered

Distance is calculated as:

[tex]Distance = Speed * Time[/tex]

Substitute values for Speed and Time

[tex]Distance = 80km/hr * 0.5hr[/tex]

[tex]Distance = 80km * 0.5[/tex]

[tex]Distance = 40km[/tex]

Hence, you travelled 40km

Answer:

I just looked up the types of matter energy has.

Explanation:

I believe the answer is D.

Sally's list of matter that have energy is not complete as all the types of matter have energy as all matter have mass , and mass and energy are related, so she should have added gases and solids to her list.

Matter in chemistry, is defined as any kind of substance that has mass and occupies space that means it has volume .Matter is composed up of atoms which may or not be of the  same type.

Atoms are further made up of sub atomic particles which are the protons ,neutrons and the electrons .The matter can exist in various states such as solids, liquids and gases depending on the conditions of temperature and pressure.

The states of matter are inter convertible into each other by changing the parameters of temperature and pressure.

Answer:

0.1mole

Explanation:

Given parameters:

Pressure = 0.0884atm

Temperature  = 6°C  = 6 + 273  = 279K

Volume occupied  = 26.5L

Unknown:

Number of moles  = ?

Solution:

To solve this problem, we are going to use the ideal gas equation:

           PV  = nRT

P is the pressure

V is the volume

n is the number of moles

R is the gas constant  = 0.082atmLmol⁻¹k⁻¹

T is the temperature.

  Insert the parameters and solve for n;

     0.084 x 26.5  = n x 0.082 x 279

              n  = 0.1mole

Answer: Convection Currents

Explanation:

Due to the different   temperature occurring at the  upper and lower layers  of the mantle, it causes  heat transfer to occur. One of such heat transfer is the Convection currents which causes  warmer, less dense rock material in the core to rise through the mantle. Also, the cooler rocks in the higher mantle move slowly towards the core.The movement caused by these  Convection current in the Earth are  called plate tectonics which are responsible for earthquakes and volcanoes.

Answer:

T₁ = 563.19 K

Explanation:

Given data:

Initial volume = 359 mL

Final volume = 269 mL

Final temperature = 422 K

Initial temperature = ?

Solution:

The given problem will be solve through the Charles Law.

Charles Law:

According to this law, The volume of given amount of a gas is directly proportional to its temperature at constant number of moles and pressure.

Mathematical expression:

V₁/T₁ = V₂/T₂

V₁ = Initial volume

T₁ = Initial temperature

V₂ = Final volume  

T₂ = Final temperature

Now we will put the values in formula.

V₁/T₁ = V₂/T₂

T₁ = V₁T₂ / V₂

T₁ = 359 mL × 422 K / 269 mL

T₁ = 151498 mL.K / 269 mL

T₁ = 563.19 K

Answer:

[tex]1.167\times 10^{-3}\ \text{mol/h}[/tex]

Explanation:

[tex]R_1[/tex] = Rate of diffusion of [tex]CO_2[/tex] = [tex]9.31\times 10^{-4}\ \text{mol/h}[/tex]

[tex]R_2[/tex] = Rate of diffusion of [tex]N_2[/tex]

[tex]M_1[/tex] = Molar mass of [tex]CO_2[/tex] = 44.01 g/mol

[tex]M_2[/tex] = Molar mass of [tex]N_2[/tex] = 28.0134 g/mol

From Graham's law we have the relation

[tex]\dfrac{R_1}{R_2}=\sqrt{\dfrac{M_2}{M_1}}\\\Rightarrow R_2=\dfrac{R_1}{\sqrt{\dfrac{M_2}{M_1}}}\\\Rightarrow R_2=\dfrac{9.31\times 10^{-4}}{\sqrt{\dfrac{28.0134}{44.01}}}\\\Rightarrow R_2=1.167\times 10^{-3}\ \text{mol/h}[/tex]

The rate of effusion of the [tex]N_2[/tex] gas would be [tex]1.167\times 10^{-3}\ \text{mol/h}[/tex].

Answer:

399.88 [tex]\frac{4.05*10^{23} }{6.022*10^{23} }[/tex] =269

Explanation:

399.88 is the molar mass of iron(III) sulfate.

The mass of 4.05 × [tex]10^{23[/tex] formula units of Fe2(SO4)3 is approximately 6.48 × [tex]10^{25[/tex] grams.

To calculate the molar mass of Fe2(SO4)3, we need to determine the atomic masses of the individual elements involved and multiply them by their respective subscripts:

Fe2(SO4)3 consists of 2 iron atoms, 3 sulfur atoms, and 12 oxygen atoms:

Molar mass of Fe2(SO4)3 = (2 * 55.845) + (3 * 32.06) + (12 * 16.00) = 159.69 g/mol

To calculate the mass of 4.05 × 10^23 formula units of Fe2(SO4)3, we can use the molar mass:

Mass = (4.05 × 10^23) * (159.69 g/mol) = 6.48 × 10^25 g

Rounded to two decimal places, the mass of 4.05 × [tex]10^{23[/tex] formula units of Fe2(SO4)3 is approximately 6.48 × [tex]10^{25[/tex] grams.

#SPJ6

Answer:

Explanation:

The reaction expression is given as:

           ⁴⁰₁₈ Ar   →   X  +  ⁰₁B  

To solve this problem, we must bear in mind that both mass number and atomic number must be conserved.

 So;

For the mass number:

               40  = A + 0

                 A  = 40

For atomic number:

                 18  = Z + 1

                  Z = 18 - 1  = 17

An atom is identifiable by the atomic number. Since the atomic number of X is 17 then it is Cl, chlorine
