The characteristic that would be most helpful would be grain sizes of the rocks. <span>Extrusive rocks are immediately exposed to the elements, and therefore cool very rapidly, and there's not really adequate time for grain size to get that large. </span><span>Intrusive rocks, on the other hand, can cool very slowly, and therefore grain size can grow to quite a large size.</span>

yaroslaw [1]

Answer:

low-spin complexes contain the maximum number of unpaired electrons.

Explanation:

In the crystal field theory, the magnitude of crystal field splitting and the pairing energy determines whether a complex will be low spin or high spin.

Low spin complexes often have greater magnitude of crystal field splitting energy than low spin complexes.

High spin complexes have maximum number of unpaired electrons(most of the electrons are unpaired) while low spin complexes have a minimum number of unpaired electrons in a complex(most of the electrons are paired).

Minerals with the silicon-oxygen structure shown in Figure 2-1 are classified into what group?
Snowcat [4.5K]

Answer : Option D) Silicates.

Explanation : The minerals with the silicon-oxygen structures are classified as silicates.

As per the definition, A silicate is any member of a family which has anions consisting of silicon and oxygen, usually they have the general formula as [SiO].

It usually has a structure which has a central silicon ion which has a charge of (+4) while each oxygen has a charge of negative two (-2) and thus each silicon-oxygen bond is equal to one half (1/2) of the total bond energy of oxygen. Therefore, it confirms that the answer is Silicates.

A balloon is filled with 500mL of helium at a temp of 27C and 75mmHg. What volume in mL will it have when it reaches an altitude
pickupchik [31]

Answer:

The answer to your question is: V = 60.3 ml

Explanation:

Data

V1 = 500 ml

T1 = 27°C = 300°K

P1 = 75 mmHg = 0.098 atm

V2 = ?

T2 = - 33°C = 240°K

P2 = 0.65 atm

Formula

                            \frac{P1V1}{T1}  = \frac{P2V2}{T2}

                            V2 = \frac{P1V1T2}{T1P2}

                            V2 = \frac{(0.098)(500)(240)}{(300)(0.65)} \

                            V2 = \frac{11769}{195}

                            V2 = 60.3 ml
