<u>Answer:</u> The correct answer is that they are formed below Earth's surface.
<u>Explanation:</u>
Plutons are defined as the intrusive igneous rocks named as plutonic rocks which are formed when the magma gets cools down slowly and solidifies below the Earth's surface.
It is different from volcanic rocks which are formed when lava gets cools down and solidifies on the Earth's surface.
Hence, the correct answer is that they are formed below Earth's surface.
Answer:
The object A will be having the greater density compared to object B.
Explanation:
It is known that density of any object is defined as the mass of any object occupying a given volume. So the ratio of mass and volume will help to determine the density of any object.
From the above equation, it can be seen that the density of any object is directly proportional to the mass of the object and inversely proportional to the volume occupied by the object.
So in the present context, the mass of objects A and B are same and it is 100 g. Thus, the density of object A and object B will be influenced by their volume. As it is given that the volume of object A is 50 cm3 and object B is 100 cm3, then depending upon the relationship of volume and density, the density of both the objects can be determined. As the object with higher volume will be having lesser density as volume is inversely proportional to density. Thus, in the given case the volume of object B is greater than object A and so the object A will be having greater density compared to object B.
Answer: 8.3 moles
Explanation:
Number of moles of lithium = ?
Mass in grams = 25 grams
Molar mass of lithium = 3g/mol
Recall that:
Number of moles = (Mass in grams / Molar mass)
Number of moles = 25 grams / 3g/mol
= 8.3 moles
Thus, there are 8.3 moles of lithium in 25 grams of lithium
