Scientist are studying photosynthesisIn in a forest ecosystem that has plants animals and decomposers
Answer:
Ecosystem is food web of primary and secondary producers and consumers.
Explanation:
In an ecosystem, there exist primary producers, primary consumers, secondary consumers, and tertiary consumers such as detritivorous such as viruses and bacteria that act on the living bodies and recycle the nutrients back to plants through the soil. The primary producers such as all green plants and others make their own food being autotrophs they use sunlight and carry out photosynthesis process. On the depend on the herbivorous they eat grass etc. The secondary consumers are carnivores as heterotrophs that feed on herbivores.Use your knowledge of atoms, bonding, and the periodic table to complete the chemical equation .”CH4 + O2

What Effect on the temperature of a boiling liquid and on it's distillation temperature is produced by a soluble nonvolatible impurity
Answer:
What effect on the temperature of a boiling liquid and on its distillation temperature is produced by each of the following?(a)A soluble, nonvolatile impurity? It would cause the mixture to boil at higher temperature and increase the distillation temperature.
It would cause the mixture to boil at a higher temperature and increase the distillation temperature.
What is distillation?Distillation is a process involving the conversion of a liquid into a vapour that is subsequently condensed back to liquid form.
During distillation, substances separate based on their boiling points. The boiling point of the mixture varies as vapour rises in a distillation column, due to changes in temperature and pressure. This process divides distillation into stages.
Hence, It would cause the mixture to boil at a higher temperature and increase the distillation temperature.

Many ski resorts and mountain cities can be reached directly by planes which deposit travelers a mile or more above sea level. This can result in altitude sickness due to hypoxemia, or reduced oxygen in the blood, caused by the unaccustomed exposure to the lower atmospheric pressure at high elevations. On a given day, the prevailing atmospheric pressure in Albuquerque, NM (elevation 1620 meters) might be 0.799 atm. Calculate this pressure expressed in mmHg and in torr. Relationship between altitude and barometric pressure.
Answer:
See explanation
Explanation:
To convert from atm to mmHg
1 atm = 760 mmHg
0.799 atm = 0.799 atm * 760 mmHg/1 atm = 607.24 mmHg
To convert from atm to torr
1 atm = 760 torr
0.799 atm = 0.799 atm * 760 torr/1 atm = 607.24 torr

40 g of NaCl is added to 1500 g of water. What is the molality of the resulting
solution?
Molality = moles of solute/mass (in kg) of solvent
The solute here is NaCl, of which you have 40 g or 40/58.4428 = 0.6844 moles NaCl.
The solvent here is water, of which you have 1500 g or 1.500 kg H2O.
The molality of the resulting solution would thus be 0.6844 moles NaCl/1.500 kg H2O = 0.4562 mol/kg.
If you have to consider sig figs, then your final answer would have one sig fig (40 g has one sig fig). In that case, your final answer would be 0.5 mol/kg.

This unit discusses in detail the role of catalysts to lower the activation energy of reactions. The term catalyst appears in nonscientific discussions to refer to something that provokes or speeds significant change or action. Consider this example from the 2006 Associated Press article "Chernobyl cover-up a catalyst for glasnost":
"For the Soviet Union, Chernobyl was a catalyst that forced the government into an unprecedented show of openness that paved the way for reforms leading to the Soviet collapse"
Discuss how this scientific term has made its way into common usage. Does the term catalyst carry the same meaning in regular usage? How is it used differently in a scientific context compared to a nonscientific contexte
Answer:
It can be brought into regular conversation easily I feel it means to "provoke" or "speeds significant change or action" I can see someone saying that in a conversation, "chlorine acts as a catalyst promoting the breakdown of ozone".
I would say it would take the same meaning depending on how you say it and when and what the context of what you're saying it in.
For scientists, it means to change quickly. For someone who says it in a conversation may be saying to stop provoking someone.

If you have 12 atoms of hydrogen before a chemical reaction, how many atoms of hydrogen will be present
Answer:
12 atoms of hydrogen will be present in the product
Explanation:
12 atoms of hydrogen will be present in the product because the law of conservation of mass states that mass is neither created nor destroyed in chemical reactions.
The law of conservation states that the mass of the element remains the same during the course of the reaction.
The law of reaction conformed by the following:-
Mass of reactant Mass of productAccording to the question, the amount of hydrogen is 12 atoms in the reactant and the amount will remain the same at the end of the reaction, which is a product that is 12 atoms
Hence, the amount remains the same in the reaction that is 12 atoms

Suppose Rutherford's lab was 10 meters (m) long and the speed of an alpha particle is 3.0x10^8 meters per second (m/s). How much time would he plan on the alpha particles taking to move from the alpha particle source to the gold foil target? Write it in a mathematical equation
Answer:
t = d/v , 33.3 ns
Explanation:
Since distance, d = vt where v = speed and t = time taken to cover the distance.
Since the distance, d covered by the alpha particle is the length of Rutherford's lab which is 10 m long and the speed of the alpha particle is v = 3 × 10⁸ m/s, the time, t it takes the alpha particle to move from the alpha particle source to the gold foil target is thus
t = d/v
= 10 m/3 × 10⁸ m/s
= 10/3 × 10⁻⁸ s
= 3.33 × 10⁻⁸ s
= 33.3 × 10⁻⁹ s
= 33.3 ns

A. Hexane will dissolve with ammonia if you stir them together for 10 minutes
B. Ammonia and hexane will not dissolve because one molecule is polar and the other is non polar.
C. Ammonia and hexane will dissolve together
D. Ammonia and hexane will not dissolve because one molecule is ionic and the other is non polar
2. If you add water to 750.0 mL of a 2.800 M KCl solution, and its molarity changes to 1.500 M, what will the new volume be?
1200 mL
401.0 mL
1400 mL
800.0 mL
Answer:
1. B. Ammonia and hexane will not dissolve because one molecule is polar and the other is non polar.
2. 1400 mL
Explanation:
In chemistry, like dissolve like! Ammonia is a polar molecule having a significant dipole moment owing to its three N-H bonds. On the other hand, hexane is a purely non-polar hydrocarbon hence the two substances can never dissolve in each other.
From the dilution formula;
C1V1=C2V2
C1= Initial concentration of the solution
V1 = Initial volume of the solution
C2 = Final concentration of the solution
V2= Final volume of the solution
2.8 M * 750.0 mL = 1.5 M * V2
V2 = 2.8 M * 750.0 mL/1.5 M
V2 = 1400 mL

The value of Kp for the reaction 2 A(g) + B(g) + 3 C(g) → 2 D(g) + E(g) is 18530 at a particular temperature. What would be the value of Kp for the reaction 2 D(g) + E(g) → 2 A(g) + B(g) + 3 C(g)?
Answer:
[tex]Kp2=5.3967x10^{-5}[/tex]
Explanation:
Hello there!
In this case, since the Kp for the first reaction is given, according to the following equilibrium expression:
[tex]Kp=\frac{p_D^2p_E}{p_A^2p_Bp_C^3} =18530[/tex]
However, since the second reaction stands for the reverse of the initial one, the equilibrium expression would be:
[tex]Kp_2=Kp=\frac{p_A^2p_Bp_C^3}{p_D^2p_E}[/tex]
And therefore its Kp the inverse of the aforementioned one:
[tex]Kp2=1/18530\\\\Kp2=5.3967x10^{-5}[/tex]
