Really it matters on which head you start the flip on. Whichever head you start with, there's a 51% chance to land on that one. If you start with heads, it would be 255 times.

What Is Chemogeny ( Chemical Evolution ) ? And Explain The Steps Of Chemogeny [Both Answer In Simple Word/ Simple Answer Which I
solniwko [45]

Answer:

Chemogeny may be a theory of chemical evolution that depends on the chemical reactions and formation of drugs on the bases of chemical reactions. This theory says that “Life occurs as a results of evolution of inorganic matter”.

In the 1920's Scientists Oparin and Haldane, developed this hypothesis of the chemical origin of life from the primitive atmosphere of the world having matter like methane, ammonia and water. there have been very low concentrations of oxygen thanks to the presence of high temperatures like 5000-60000C. So, these conditions weren't suitable for the free existence of organic compounds, so reactions started happening .

Under conditions like high sunlight and warmth , inorganic matter gets converted to inorganic compounds. And this might end in the storage of organic compounds, which gets more and more concentrated with the passage of many years.

These compounds interact with one another and end in “life”.

So, chemogeny is that the process of chemical evolution of earth and formation of life from pre-existing matter with the assistance of chemical reactions.

Explanation:

Hopefully I was able to help you with the concept. Good luck!

How is the density of ocean water affected by temperature and water?
Sedaia [141]

Answer:

There are two main factors that make ocean water more or less dense than about 1027 kg/m3: the temperature of the water and the salinity of the water. Ocean water gets more dense as temperature goes down. So, the colder the water, the more dense it is. Increasing salinity also increases the density of sea water.

An electric clothes dryer draws 20 A of current from a 240-V wall outlet. How much power, in watts, does it use?
TEA [102]

An electric clothes dryer that draws 20 amps of current from a 240-volt wall outlet will use 4800 watts of power.

The equation is P(W) = I(A) × V<span>(V)</span>

<span>P(W)= amp x voltage</span>

<span>20 amps x 240 volts = 4800 watts.</span>
