4 limiting factors could be water, space, pollution, and access to mates, could all be factors in limiting the native population. Water, could be affected by pollution, and this would remove water, which means that no living things would be able to survive, or at the best be hindered in its growth. Space could be removed by deforestation, or simple water rising, and this could kill off the population, thus removing mates for the population. (hope this helped, if it did, please consider marking brainiest)
The availability of food, water, shelter and diseases are the four limiting factors in the local ecosystem and their impact on native populations.
What are the limiting factors?The limiting factors such as availability of food, water, shelter and diseases can change animal and plant populations because these factors has a direct impact on the organisms and the organisms is depend on these factors for their survival.
So we can conclude that availability of food, water, shelter and diseases are the four limiting factors in the local ecosystem and their impact on native populations.

A Jeweler is making sapphire rings using 2 sapphires on every 1 ring. If the jeweler has 12 sapphires and 10 rings, what is the theoretical yield? (3 points)
O 5 sapphire rings
O 6 sapphire rings
O 10 sapphire rings
O 12 sapphire rings
3 (05 05 LC)
The theoretical yield is 6 sapphire rings.
What is Theoretical yield?This is the total product formed as a result of the complete conversion of
the reactants. In this scenario, the reactant is the 12 sapphires in which 2
of it is needed to produce one sapphire ring.
This however translates to the theoretical yield being 6 sapphire rings
which is gotten by:
2 sapphires = 1 ring
12 sapphires = x
Cross multiply
2x = 12
x= 12/2 = 6 sapphire rings.

Most of the deserts on the Earth are located around 30°N & 30°S latitude. This is because air is ( rising / sinking ) at these locations.
Answer: We live at the bottom of a gaseous envelope the atmosphere--that is bound gravity to the planet Earth. The circulation of our atmosphere is a complex process because of the Earth's rotation and the tilt of its axis. The Earth's axis is inclined 23.5° from the ecliptic, the plane of the Earth's orbit around the Sun. Due to this inclination, vertical rays of the Sun strike 23.5° N. latitude, the Tropic of Cancer, at summer solstice in late June. At winter solstice, the vertical rays strike 23.5° S. Latitude, the Tropic of Capricorn. In the Northern Hemisphere, the summer solstice day has the most daylight hours, and the winter solstice has the fewest daylight hours each year. The tilt of the axis allows differential heating of the Earth's surface, which causes seasonal changes in the global circulation. On a planetary scale, the circulation of air between the hot Equator and the cold North and South Poles creates pressure belts that influence weather. Air warmed by the Sun rises at the Equator, cools as it moves toward the poles, descends as cold air over the poles, and warms again as it moves over the surface of the Earth toward the Equator. This simple pattern of atmospheric convection.

Answer: 2Cr + 3Br2 Yields 3CrBr3
Explanation:
We know that 4a is not balanced because there are 3 Nitrogen atoms on the reactants side and 2 on the products side.
We know that 4c is not balanced because there are 4 Chlorine atoms on the reactants side and 2 on the products side. (Remember there are 2 Cl2 atoms. Therefore, 2 times 2 means there are 4 Chlorine atoms on the reactants side)
Finally, we know the answer is not 4d because there is 1 Potassium on the reactants side and 2 potassiums on the products side.
Therefore, the answer must be 4b, which contains 2 Chromium atoms and 6 bromine atoms on each side

1. Mercury is most often obtained by roasting cinnabar (HgS). How many grams of cinnabar
are required to obtain 165 grams of mercury?
HgS + 02—-Hg + SO2
Answer:
191.4 grams of cinnabar are required to obtain 165 grams of mercury.
Explanation:
The balanced reaction is:
HgS + O₂ ⇒ Hg + SO₂
By reaction stoichiometry, the following amounts of moles of each compound participate in the reaction:
HgS: 1 mole O₂: 1 mole Hg: 1 mole SO₂: 1 moleBeing the molar mass of each compound:
HgS: 232g/moleO₂: 32 g/moleHg: 200 g/moleSO₂: 64 g/molethe following mass amounts of each compound participate in the reaction:
HgS: 1 mole* 232 g/mole= 232 gO₂: 1 mole* 32 g/mole= 32 gHg: 1 mole* 200 g/mole= 200 gSO₂: 1 mole* 64 g/mole= 64 gThen you can apply the following rule of three: if by stoichiometry 200 grams of Hg are formed from 232 grams of HgS , 165 grams of Hg are formed from how many grams of HgS?
[tex]mass of HgS=\frac{165 grams of Hg*232 grams of HgS}{200 grams of Hg }[/tex]
mass of HgS= 191.4 grams
191.4 grams of cinnabar are required to obtain 165 grams of mercury.
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

What is the mass of water released by the heating? Show your work or explain your reasoning.
Answer:
Dividing the mass of the water lost by the original mass of hydrate used is equal to the fraction of water in the compound. Multiplying this fraction by 100 gives the percent water in the hydrate.
Explanation:
The amount of water throughout the compound has been determined by dividing the mass of water wasted mostly by original quantity of hydrate used. The above fraction can be multiplied by 100 to get the hydrate's water content in percentages.
What is mass ?The proportion of matter that makes up an object is quantified by its mass. The kilogram, or kg, would be the fundamental SI unit of mass.
What is hydrate?Any substance that contains water through the form of H2O molecules is referred to as a hydrate. This water content by weight can vary, but it is typically fixed. The most well-known hydrates seem to be crystalline solids which decompose once the attached water is removed.
Therefore , The amount of water throughout the compound has been determined by dividing the mass of water wasted mostly by original quantity of hydrate used. The above fraction can be multiplied by 100 to get the hydrate's water content in percentages.

A student titrates an unknown weak acid, HA, to a pale pink phenolphthalein endpoint with 25.0 mL of 0.100 M NaOH. The student then titrates in 11.0 mL of 0.100 M HCl to the solution containing the neutralized unknown acid (HCl was delivered from a second buret). The pH of the resulting solution is pH
Answer:
Hello your question is incomplete the pH of the solution is unknown hence I will take the pH of the solution be = 4.7
answer : Pka = 5 i.e. > 4.7
Explanation:
Student titrates :
Unknown weak acid ( HA ) with 25 mL of 0.100 M of NaOH ( to a pale pink phenolphthalein endpoint ) then titrates with 11.0 mL of 0.100 M HCL to the solution that contains neutralized unknown acid
Assuming pH of solution = 4.7
HA + NaOH --------> H2O + NaA
at equilibrium point
0.1 * 25 * 1 = n * 1 ∴ [tex]n_{ha}[/tex] = 2.5 mmoles ------ 1
also
[tex]A^-[/tex] + HCL ---------> HA + C[tex]L^-[/tex]
at equilibrium point
[tex]n_{a}[/tex] = 1.1 mmoles --------- 2
The ratio of reaction 2 to 1
[tex]\frac{n_{a} }{n_{ha} }[/tex] = 1.1 / 2.5 ≈ 1/2 ( this show that when the pH = 4.7 approximately half of the A^- have been converted to HA )
Determine the pKa value of the solution
Given that
pH = Pka + log ( A^- / hA )
4.7 = Pka + log ( 1/2 )
therefore Pka = 4.7 - ( -0.3 ) = 5
An artificial vesicle containing a 1 M glucose solution is composed of a phospholipid bilayer lacking any protein components other than aquaporin channels. Assuming an ideal solution, what is the ratio of the osmotic pressure measured immediately after immersion of the vesicle in de-ionized water to the osmotic pressure measured immediately after immersion of an identical vesicle containing the original volume of 1 M glucose solution added to an equal volume of 1 M KCl solution in deionized water
Answer:
A: 0.67
The situation described in the question is analogous to a semipermeable membrane. Water is able to pass through aquaporin channels present in the liposome, but large uncharged particles (glucose) and ions (K+ and Cl -) are impermeable and will remain trapped within the liposome. If assumed to be ideal, the osmotic pressure, π, exerted by the solution due to molarity differences across the membrane is defined as π = iMRT, where i is the van't Hoff factor, M is the molarity of the solution, R is the universal gas constant, and T is the absolute temperature of the solution. A change in osmotic pressure at constant temperature is due to changes in iM, a term that is equivalent to the concentration of dissolved particles produced by solute in solution. When compared to the original volume of 1 M glucose, the new combined solution has twice the volume and three times the number of dissolved particles (1 M KCl, a strongly electrolytic solution, produces 1 M concentrations of both K+ and Cl- in solution), or an increase in the concentration of dissolved particles by a factor of 1.5. This is equivalent to a combined molarity of dissolved particles of 1.5 M. The ratio of osmotic pressure is then [1 M dissolved glucose] / [1.5 M dissolved glucose + KCl] = 0.67
