5 0

Answer:

0.2257kg

Explanation:

Using the formula density= mass/ volume

  • density=22.57g/cm³
  • volume=1*4*2.5cm³= 10cm³
  • mass is unknown

22.57g/cm³=mass/10cm³

  • cross multiply

mass = 22.57g/cm³*10cm

=225.7g

but in kg

  • convert to kg
  • 225.7/1000

= 0.2257kg

In covalent bonds, atoms share electrons to fill up energy levels.<br><br> True or False
Nadusha1986 [10]

Most _______ rocks form under conditions found a few kilometers under earths surface
12345 [234]
Most metamorphic processes takes place few kilometers below the Earth's surface. Thus, "metamorphic rocks" are formed under conditions found few kilometers under the Earth's surface.
Sedimentary rocks are formed by the compaction of sediments. Two main groups of sedimentary rocks are clastic sedimentary rocks and chemical sedimentary rocks.
Metamorphism refers to the changes in the mineral composition of the rocks. The three agents of metamorphism are heat, pressure and water.
The conversion of one form of rock to another is referred as rock cycle. In a rock cycle, an igneous rock formed from the deposition of molten magma can get converted into sedimentary rock when igneous rock breaks down into pieces and sediments. Finally, the any sedimentary rock or igneous rock can undergo metamorphosis to form metamorphic rocks. Metamorphic rock can again form igneous rock by melting of magma followed by crystallization.

Example of market structures of monopoly
IgorC [24]

Answer: A monopoly is the absence of competition in the market.

Explanation:

In such circumstances, the market creates a monopoly of one producer who takes huge capital and dictates prices. An example of a monopoly on the market is the existence of only one company that makes up the entire economic branch. In such circumstances, the monopolist can increase the product's price without losing the entire sale, i.e., operating successfully. In that situation, the monopolist remains the only one on the market, and the competition has no access to the market.
