Answer:

Option b

Explanation:

Metamorphism is the process where the variation of the geological texture resulting from the different arrangement of the minerals or the variation of minerals in protoliths, i.e., pre- existing rocks take place such that there occurs no change in state of the protolith, i.e., it does not melt into magma.

The change takes place as a result of the presence of chemically active fluids, heat and pressure.

There is a reaction between the chemically active fluid and the rock through which it passes and promotes the movement of the dissolved ions of silicate and promotes the growth of the mineral grains.

If silicic rock is found in a core sample. What evidence does this provide about the rocks location ?

frez [133]

Answer:

The rocks location is underneath an ocean or mountain

Explanation:

Silicic rock are igneous rock rich in silica. The amount of silica that constitutes a silicic rock is usually defined as at least sixty three percent. Granite and rhyolite are the most common silicic rocks found. These are found in the magma of the Earth.

Silicic is the group of silicate magmas which crystallise a relatively small proportion of ferromagnesian silicates. The main constituents of a silicic rock will be minerals rich in silica-minerals mainly.

Consider the addition of an electron to the following atoms from the third period. Rank the atoms in order from the most negativ

sergeinik [125]

The question is incomplete, the atoms in the third period referred to in the question are shown in the image attached.

Answer:

Cl>Si>Ar

Explanation:

Electron affinity refers to the energy released when an atom accepts electron (s) to form a negative ion. It is a periodic property that shows similar trends as electro negativity.

Considering the atoms in period three given in the question; chlorine will have the most negative value of electron affinity. This owes to the fact that halogens accept electrons easily to form negative ions. Silicon in group 14 shows much less negative value of electron affinity while argon, a noble gas, does not accept electrons at all and has an electron affinity of zero KJMol-1 by standard.

Gallium is a solid metal at room temperature, but it will melt to a liquid in your hand. the melting point of gallium is 85.6 f.

Nimfa-mama [501]

Fahrenheit = 85.6°F

Celsius = (5/9) (Fahrenheit - 32)

Celsius = (5/9) (85.6 - 32)

Celsius = (5/9) (53.6)

<em>Celsius = 29.78°C</em>

Kelvin = Celsius + 273.15

Kelvin = 29.78 + 273.15

<em>Kelvin = 302.93K </em>

Answer:

430.

Explanation:

If we know that 0.5 is half of a whole number, then we can simply understand that we need to 215 x 2 to get our answer.
