Answer:

The C-type

The S-type

The M-type

Explanation:

C type = (chondrite) asteroids are most common, probably consist of clay and silicate rocks, and are dark in appearance.

S type = ("stony") are made up of silicate materials and nickel-iron.

M type = metallic (nickel-iron).

Answer:

S-type or silaceous asteroids are made up primarily of stony materials and nickel-iron. They inhabit the inner Asteroid Belt. M-type, or metallic, are made up mostly of nickel-iron, and are found in the middle region of the Asteroid Belt

Find the volume of 200g of benzene, if the density of benzene is 0.88 g/mL.
Lina20 [59]

Answer:

<h2>227.27 mL</h2>

Explanation:

The volume of a substance when given the density and mass can be found by using the formula

volume =  \frac{mass}{density} \\

From the question we have

volume =  \frac{200}{0.88}  \\  = 227.2727...

We have the final answer as

<h3>227.27 mL</h3>

Hope this helps you

Describe an oxidation-reduction reaction.
DaniilM [7]

Answer:   Oxidation reaction occurs when a reactant losses electrons in the reaction.

Reduction reaction occurs when a reactant gains electrons in the reaction.

Explanation: Reduction reaction : It is defined as the reaction in which a substance gains electrons. That means, the gain of electrons takes place.

Or we can say that, reduction reaction occurs when a reactant gains electrons in the reaction.

Redox reaction or Oxidation-reduction reaction : It is defined as the reaction in which the oxidation and reduction reaction takes place simultaneously.

Use the standard reduction potentials located in the 'Tables' linked above to calculate the equilibrium constant for the reactio
Paladinen [302]

Answer:

Check the explanation

Explanation:

cell CuE Ecell 0.337 (-0.14) Ecl0.477 V

Since E^o_{ cell } > 0 , the value of \Delta G^o will be negative.

\Delta G^o < 0

\Delta G^o =-nFE^o_{ cell }......(1)

But

\Delta G^o =-RT ln K......(2)

From (1) and (2)

\Delta G^o =-RT ln K=-nFE^o_{ cell }

ln K =\frac{nFE^o_{ cell } }{RT }

ln K =\frac{ 2 \times 96500 \times 0.477 }{8.314 \times \left ( 25+273.15 \right ) }

ln K =37.139

K =1.3468 \times 10^{16}

Hence, the value of the equilibrium constant is 1.35 \times 10^{16}
