Why copper should not be disposed of in landfill sites?

What the guy above said, although he focuses more on the human side. In animals the bioaccumalation can cause toxicity and diseases within them too, and it can cause large loss of life. It also limits plant growth when in high doses, so new life can't grow in the area once the landfill is covered over

Copper is a heavy metal that can harm many people. This process of heavy metals building in your body is called bioaccumulation and the process of this building in the food chain is called biomagnification. Its hard to rid of this heavy metal because it is very dense, therefore, cannot breakdown in our bodies. Heavy metals get consumed by producers and then reach to the top of the pyramid (us) so we have the highest risk of getting diseases and so on. Make sure you explain that heavy metals get passed from industrial purposes where companies do not dispose of waste properly.

How many moles of chlorine gas would occupy a volume of 35.5 L at a pressure of 100.0 kPa and a temperature of 100.0 degrees Cel

o-na [289]

1.137448506 mol moles of chlorine gas would occupy a volume of 35.5 L at a pressure of 100.0 kPa and a temperature of 100.0 degrees Celsius.

<h3>What is an ideal gas equation?</h3>

The ideal gas equation, pV = nRT, is an equation used to calculate either the pressure, volume, temperature or number of moles of a gas. The terms are: p = pressure, in pascals (Pa). V = volume, in $m^3$ .

We apply the formula of the ideal gases, we clear n (number of moles); we use the ideal gas constant R = 0.082 l atm / K mol:

PV= nRT

Given data:

P=100.0 kPa =0.986923 atm

T=100 degree celcius= 100 + 273 =373 K

V=35.5 L

Substituting the values in the equation.

n= $\frac{\;0,98 \;atm \;X \;35,5 \;L }{\;0,082\;atm / \;K mol \;X \;373 K}$

n= 1.137448506 mol

Hence, 1.137448506 mol moles of chlorine gas would occupy a volume of 35.5 L at a pressure of 100.0 kPa and a temperature of 100.0 degrees Celsius.

Nitriles can be converted into carboxylic acids. how would you use ir spectroscopy to monitor the progress of this reaction?

Lady bird [3.3K]

Fats or oils are created when the hydroxide group of glycerol combines in a dehydration synthesis process with the carboxyl group of fatty acids.

<h3>What is dehydration ?</h3>

Your body loses more fluids when you are dehydrated than you are taking in. If unattended to, it could get worse and become a serious problem.

When you don't drink enough water or lose more than you take in, you become dehydrated. Sweat, tears, vomiting, urination, and diarrhea all cause fluid loss. Climate, level of physical activity, food, and other variables can all affect how severe dehydration is.

Dark urine, decreased urination, headaches, weariness, dry skin, decreased skin turgor, and poor focus are all indicators of dehydration.
