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

Structural isomers are molecules that have the same chemical formula but different structures and chemical properties. For examp
kicyunya [14]

Answer:

Neopentane (C(CH3)4) have a lower a lower boiling point than n-pentane (CH3CH2CH2CH2CH3) because of it branched chain.

Explanation:

Structural isomers are compounds that have the same molecular or chemical formula but have different arrangement of atoms in space. The connectivity of the atoms differs for this compounds but they possess the same molecular formula. An example of structural isomers are butane and methyl propane. Usually, as the number of carbon increases for alkane the number of isomers also increases.

Since Isomers are different compound they are bound to have different characteristic both in melting and boiling points. Generally, straight chained isomers have higher boiling points than branched chain isomers.

n-pentane (CH3CH2CH2CH2CH3) is a straight chained isomer while neopentane (C(CH3)4) is a branched chain isomer.  Neopentane (C(CH3)4) have a lower a lower boiling point than n-pentane (CH3CH2CH2CH2CH3) because of it branched chain.

Calculate the solubility product constant, Ksp, of lead(II) chloride, PbCl2, which has a
V125BC [204]

Answer:

0.0159m

Explanation:

9 M

Explanation:

Lead(II) chloride,  

PbCl

2

, is an insoluble ionic compound, which means that it does not dissociate completely in lead(II) cations and chloride anions when placed in aqueous solution.

Instead of dissociating completely, an equilibrium rection governed by the solubility product constant,  

K

sp

, will be established between the solid lead(II) chloride and the dissolved ions.

Now, the molar solubility of the compound,  

s

, represents the number of moles of lead(II) chloride that will dissolve in aqueous solution at a particular temperature.

Notice that every mole of lead(II) chloride will produce  

1

mole of lead(II) cations and  

2

moles of chloride anions. Use an ICE table to find the molar solubility of the solid

What happened to particles in matter when it is heated up
vichka [17]

Answer: When heat is added to a substance, the molecules and atoms vibrate faster. As atoms vibrate faster, the space between atoms increases. The motion and spacing of the particles determines the state of matter of the substance. The end result of increased molecular motion is that the object expands and takes up more space.

Explanation: Hope this helps!

You place a balloon in a closed vacuum chamber at standard temperature and pressure (STP). You decrease the chamber temperature
leva [86]
It reduces in size by half.

This is due to Charles's law, which states that the absolute temperature and volume of a gas are directly proportional, given that pressure is kept constant. Therefore, if the absolute temperature is halved, the volume of the gas will also halve.
