Answer:

See explanation

Explanation:

We have to first put down the balanced reaction equation;

MgO+C------->CO2(g)+Mg

We then have to identify each specie in the reaction equation. The reactants are;

Magnesium oxide and carbon

The products are

Carbon dioxide and magnesium metal

So the word equation is as follows;

Magnesium oxide + carbon ----> carbon dioxide + magnesium

In a sentence form;

One mole of magnesium oxide reacts with one mole of carbon to yield one mole of carbon dioxide and one mole of magnesium metal.

In a mass spectrometer, a single-charged particle (charge e) has a speed of 1.0 × 10 6 m/s and enters a uniform magnetic field o
Nonamiya [84]

Answer:

The mass is  m  =6.4*10^{-28} \ kg

Explanation:

From the question we are told that

   The  speed of the charge is  v   = 1.0 *10^{6} \  m/s

    The  magnetic field is  B = 0.20 \ T

     The radius is r  =  0.02 \ m

      The value of the charge is  e  = 1.60 *10^{-19} \  C

The centripetal acting on the charge moving in the circular orbit is mathematically represented as

        F_c  =  \frac{mv^2}{r }

Now this centripetal force is due to the force exerted on the charge by the magnetic field on the charge which is mathematically represented as

     F_m  =  qv  B  sin\theta

At the maximum of this magnetic force \theta =  90 ^o

So  

     F_m  =  e v  B  sin(90)

      F_m  =  e v  B

Now given that it is this  magnetic force that is causing the circular motion we have that

       F_c  =  F_m

=>     \frac{mv^2}{r }  =  ev  B

=>     m  = \frac{e * B  *  r  }{v }

substituting values

       m  = \frac{ 1.60 *10^{-19} *  0.20   *  0.020   }{1.0*10^{6} }

     m  =6.4*10^{-28} \ kg

Determine the average distance between the Earth and the Sun. Then calculate the average speed of the Earth in its orbit in kilo
FrozenT [24]

Answer:

The average speed of the Earth in its orbit is 4.74 km/s.

Explanation:

Distance between the Earth and the Sun ,r= 149.60 million km = 149.60\times 10^6 km

Considering the movement of Earth  around the Sun follows circular path.

The circumference of circular path will be give by :

D=2\pi r=2\times 3.14\times 149.60\times 10^6 km

Time taken by Earth to complete revolution around earth ,T= 1 year

1 year = 365 days

1 year = 31,536,000 seconds

T = 31,536,000 seconds

Speed of the Earth around the Sun :S

S=\frac{D}{T}=\frac{149.60\times 10^6 km}{31,536,000 s}

S=4.74 km/s

The average speed of the Earth in its orbit is 4.74 km/s.
