Explanation:
It is known that 1 SCF produces approximately 1000 Btu of thermal energy.
As it is not mentioned for how many hours the gas is used in this process. Therefore, we assume that the total number of hours natural gas used in this process are as follows.
= 8760 hours
Now, we will calculate the annual cost of natural gas used in the process as follows.
= 555384000 SCF
Hence, annual cost of natural gas used in this process = loss of thermal energy
This will be equal to,
= 555,384,000,000 BTU
Thus, we can conclude that the annual cost of natural gas used in the process is 555,384,000,000 BTU.
Answer:
b option
Explanation:
H2O has a tetrahedral arrangement of molecules or an angular geometry. This is mainly because the repulsion from the lone pair combination is more than bond-pair repulsion.
Answer:
Temperature and pressure are the two factors which are responsible for change in state of matter.
Solid – In a solid, the attractive forces keep the particles together tightly enough so that the particles do not move past each other. ... In the solid the particles vibrate in place. Liquid – In a liquid, particles will flow or glide over one another, but stay toward the bottom of the container.

This would be true.
The reason why this answer would be true is because a fossil's position in the rock layers determine how long they died and were preserved. If the fossils were right next to each other, then that means both organisms were preserved at the same time.
Neutrons have no charge, protons have a +1 charge and electrons have a -1 charge so your net charge = +8 -10 so your net charge is -2
