Answer:
Hope this helps
Explanation:
Potential energy diagrams represent the energy transfer in chemical reactions in a diagram called a potential energy graph and/or a reaction progress curve. A potential energy diagram shows the adjustment in potential energy of a system as reactants are changed.
The Equator is an imaginary line around the middle of the Earth. It is halfway between the North and South Poles, and divides the Earth into the Northern and Southern Hemispheres. The Equator is the line of 0 degrees latitude. Each parallel measures one degree north or south of the Equator, with 90 degrees north of the Equator and 90 degrees south of the Equator. The latitude of the North Pole is 90 degrees N, and the latitude of the South Pole is 90 degrees S hope this helps
Considering that CCL3F gas behave like an ideal gas then we can use the Ideal Gas Law
<span>PV = nRT, however is an approximation and not the only way to resolve this problem with the given data..So,at the end of the solution I am posting some sources for further understanding and a expanded point of view. </span>
<span>Data: P= 856torr, T = 300K, V= 1.1L, R = 62.36 L Torr / KMol </span>
<span>Solving and substituting in the Gas equation for n = PV / RT = (856)(1.1L) /( 62.36)(300) = 0.05 Mol. This RESULT is of any gas. To tie it up to our gas we need to look for its molecular weight:MW of CCL3F = 137.7 gm/mol. </span>
<span>Then : 0.05x 137.5 = 6.88gm of vapor </span>
<span>If we sustract the vapor weight from the TOTAL weight of liquid we have: 11.5gm - 6.88gm = 4.62 gm of liquid.d</span>
Answer:
Explanation:
mass of the solution = volume x density = 200 x 1 = 200 gm
heat absorbed = m x s x Δ t , s is specific heat , Δt is rise in temperature
= 200 x 4.18 x ( 31.3 - 24.6 )
= 5601 J .
This is the enthalpy change required.
Answer:
Explanation:
When I was growing up, one of the most popular cartoons was a little possum whose name was Pogo. He often said
“We have met the enemy and he is us.”
It is something Pogo said more than once. We are the problem with biodiversity being threatened.
We clear land for agriculture, not only in Canada and the United States, but in places like Brazil where it matters what is done to the environment. Those trees are the planet's lungs. Whole environmental groups are devoted to stopping the harvesting of trees that are hundreds of years old.
Our oceans have become cesspools of plastic.
Our rivers have become dumping grounds for all kinds of pollutants like paint and car tires to name just a couple.
Our landscape has been cluttered by billboards advertising things that are hundreds of miles away.
There's mining, oil, and other industries that make Mother Nature shudder every time they come near her.
