Answer:
Ammonia is a toxic product of nitrogen metabolism which should be removed from our body.
The urea cycle or ornithine cycle converts excess ammonia into urea in the mitochondria of liver cells.
The urea forms, then enters the blood stream, is filtered by the kidneys and is ultimately excreted in the urine.

What is the molarity of a solution that contains 114.4g NaCl (molar mass= 58.44 g/mol) in 1.2 L solution?
Answer:
1.6 M.
Explanation:
We want to find the molarity of a solution that contains 114.4 g NaCl in a 1.2 L solution.
Recall that molarity is given by:
[tex]\displaystyle \text{M} = \frac{\text{ mols solute}}{\text{ L soln.}}[/tex]
Convert 114.4 g NaCl to mol NaCl using its molecular weight:
[tex]\displaystyle 114.4 \text{ g NaCl} \cdot \frac{1 \text{ mol NaCl}}{58.44 \text{ g NaCl}} = 1.958\text{ mol NaCl}[/tex]
Therefore, the molarity of the solution will be:
[tex]\displaystyle \text{M} = \frac{1.958 \text{ mol NaCl}}{1.2\text{ L soln.}} = 1.6 \text{ M}[/tex]
In conclusion, the molarity of the solution is 1.6 M.
is it possible to convert molecule to molecule?
Answer:
yes, it's possible to covert molecule to molecule
Explanation:
Converting between molecules and moles is done by either multiplying by or dividing by Avogadro's number.

what is the difference between cyclic compound and straight chain compound in hydrocarbons reaction
Explanation:
Cyclic Hydrocarbons
A cyclic hydrocarbon is a hydrocarbon in which the carbon chain joins to itself in a ring. A cycloalkane is a cyclic hydrocarbon in which all of the carbon-carbon bonds are single bonds. Like other alkanes, cycloalkanes are saturated compounds. Cycloalkanes have the general formula CnH2nCnH2n. The simplest cycloalkane is cyclopropane, a three-carbon ring.

A chunk of sulfur has a volume of 8.33 cm3. What is the mass of this sulfur? (Density of sulfur = 2.07 g/cm3.)
Explanation:
equations to note:
density= mass/volume
mass= volume *density
volume= mass/density
you have a volume- 8.33cm3
you have a density- 2.07 g/cm3
Answer:
8.33cm3 * 2.07g/cm3= 17.24g
mass= 17.24g
Calculate the volume of an object with a density of .85 g/mL and a mass of 212 g.
[tex]\\ \sf\longmapsto Volume=\dfrac{Mass}{Density}[/tex]
[tex]\\ \sf\longmapsto Volume=\dfrac{212}{0.85}[/tex]
[tex]\\ \sf\longmapsto Volume=249.4mL[/tex]
Answer:
[tex]249.41 \: ml[/tex]
Explanation:
[tex]volume = \frac{mass}{density} \\ = \frac{212g}{0.85 \: g \: {ml}^{ - 1} } \\ = 249.41 \: ml[/tex]

Which element is the most reactive?
Answer:
Cesium
Explanation:
Cesium is second from the bottom of this group, has 6 shells of electrons, and it matches the features of a reactive atom, making it the most reactive element.
1) Is a moth bursting out of cocoon a chemical or physical change? (I put chemistry because i didn't know what else to put) 2) Is playing with purple and green slime chemical or physical change
Answer:
1)A moth bursting out of a cocoon is neither a chemical or physical change, it's a biological change. If I had to chose it would be a physical change though. Not to sure...
2)Playing with slime is a physical change.
Explanation:
1)The reason why I would chose physical change is because the moth is changing it's physical state more than it's chemical composition, but you should say both if that's an option.
2)A physical change is when the temperature, shape, or state of matter changes. A chemical change occurs when the actual substance changes. An example of this is a chemical reaction. Because the slime is changing shape and not substances, I would say that it's obviously a physical change.
Hope this helps, sorry that I'm not too sure about the 1st question.
Calculate the molarity of each of the following solutions.
1.30 mol of KNO3 in 250.0 mL of solution
0.500 mol of BaCl2 in 100.0 mL of solution
0.195 mol of Na2CO3 in 200.0 mL of solution
7.00 mol of C6H12O6 in 250.0 mL of solution
Answer:
5.2M, 5M, 0.975M, 28M
Explanation:
M = ( moles × 1000 ) ÷ volume
Molarity is affected by temperature. Its unit is mole/litre. It measure the concentration of any solute in a solution. Thus the molarity of [tex]KNO_{3}[/tex],[tex]BaCl_{2}[/tex],[tex]Na_{2}CO_{3}[/tex] and[tex]C_{6}H_{12}O_{6}[/tex] are 5.2mol/litre, 5mol/litre, 0.97mol/litre, 28mol/litre respectively.
What is molarity?
Molarity can be calculated by dividing number of moles of solute by volume of solution in liter.
Other concentration terms are molality, normality and mole fraction. Molarity can be used to find out the ionic strength of any solution
Mathematically,
Molarity= number of moles of solute/volume of solution in litre (1)
1) Molarity of [tex]KNO_{3}[/tex]= {1.30 mol ×(1000ml/l)}÷250.0 mL=5.2mol/litre
2)Molarity of [tex]BaCl_{2}[/tex]= {0.500 mol ×(1000ml/l)}÷100.0 mL=5mol/litre
3)Molarity of[tex]Na_{2}CO_{3}[/tex]= {0.195 mol ×(1000ml/l)}÷200.0 mL=0.97mol/litre
4)Molarity of [tex]C_{6}H_{12}O_{6}[/tex] = {7.00 mol ×(1000ml/l)}÷ 250.0 mL=28mol/litre
Thus the molarity of [tex]KNO_{3}[/tex],[tex]BaCl_{2}[/tex],[tex]Na_{2}CO_{3}[/tex] and[tex]C_{6}H_{12}O_{6}[/tex] are 5.2mol/liter, 5mol/litre, 0.97mol/litre, 28mol/litre respectively.

What state does a gas turn into if it reaches it freezing point?
O Solid
O Liquid
Gas
O None of the above
Answer:
Solid
Explanation:
According to Wikipedia
Deposition is the phase transition in which gas transforms into solid without passing through the liquid phase. Deposition is a thermodynamic process. The reverse of deposition is sublimation and hence sometimes deposition is called desublimation.
How are physical changes related to state of matter changes?
Answer:
Changes of state are physical changes. They occur when matter absorbs or loses energy. Processes in which matter changes between liquid and solid states are freezing and melting. Processes in which matter changes between liquid and gaseous states are vaporization, evaporation, and condensation.

What did Fermi mean when he said, "The reaction is self-sustaining"?
The reaction reached critical mass.
A spontaneous chain reaction had been accomplished.
The nuclear reaction was out of control.
The nuclear reaction could be controlled and maintained.
Answer:
The nuclear reaction could be controlled and maintained.
Explanation:
People had initiated a self-sustaining nuclear reaction--and then stopped it. He had released the energy of the atom's nucleus and controlled that energy.
Fermi's achievement in setting off the first self-sustaining nuclear chain reaction from his design of an atomic pile led to a new Age of the Atom. The controlled release of nuclear energy was now a reality
