Answer:
[tex]\boxed {\boxed {\sf P_2= 9 \ atm}}[/tex]
Explanation:
Since the temperature is held constant, we only need to focus on the volume and pressure. We will use Boyle's Law, which states the volume of a gas is inversely proportional to the pressure. The formula is:
[tex]P_1V_1=P_2V_2[/tex]
Originally, the gas had a volume of 150 milliliters and a pressure of 3.0 atmospheres. We can substitute these values into the left side of the equation.
[tex]3.0 \ atm * 150 \ mL = P_2V_2[/tex]
The original gas was compressed to a volume of 50 milliliters, but we don't know the volume.
[tex]3.0 \ atm *150 \ mL= P_2 * 50 \ mL[/tex]
Now, we need to solve for the new pressure (P₂). Multiply on the left side first.
[tex]450 \ atm*mL= P_2 * 50 \ mL[/tex]
Since we are solving for the pressure, we need to isolate the variable. It is being multiplied by 50 mL. The inverse of multiplication is division. Divide both sides by 50 mL.
[tex]\frac{450 \ atm*mL}{50 \ mL}= \frac{P_2 * 50 \ mL}{50 \ mL}[/tex]
[tex]\frac{450 \ atm*mL}{50 \ mL}= P_2[/tex]
The units of milliliters will cancel.
[tex]\frac{450 \ atm}{50 }= P_2[/tex]
[tex]9 \ atm =P_2[/tex]
The new pressure is 9 atmospheres.
What is the role of the producer in any food chain?
Question 1 options:
Producers turn light energy into food energy
Producers make the food that consumers eat
Without producers, consumers would starve
All of these answers are correct
Answer:
All of these answers are correct.
Explanation:
They are all correct because producers make their food(energy) through photosynthesis, they provide food to herbivores and therefore the rest of the food chain, and without them, the food chain would collapse and all the consumers would starve.
explain how soil can affect the composition of the solution that move through it
Answer: Soils are formed through the interaction of five major factors: time, climate, parent material, topography and relief, and organisms.
Soil structure affects plant growth in many, often surprising, ways. The most obvious effects are on root growth, which is strongly inhibited by hard soil, and which in turn influences the ability of the root system to extract adequate water and nutrients from the soil.

calculate the atomic mass of gallium if gallium has two naturally occurring isotopes with the following massess and natural abundances Ga-69 68.9256 amu 60.11% Ga-71 70.9247 amu 39.89
Answer: Atomic mass of gallium = 69.72304093 amu
Explanation:
We calculate the atomic mass of Gallium by using the Relative abundance of the isotopes.
Atomic mass =mass x Natural Abundance of Isotope 1 +mass x Natural Abundance of Isotope 2
(60.11/100 x 68.9256) + (39.89/100 x 70.9247)
= 41.43117816 + 28.29186283 = 69.72304093 amu
A gas occupies 4.21 Iiters at a pressure 1 074 atm. What will its volume be if the pressure is decreased to 0.46 atm?
Answer:
15.9 Liters
Explanation:
according to Boyle's law P1V1 = P2V2
so we just plug in the values the problem gives us and solve for V2
(1.74)(4.21)=(.46)(V2)
V2 = 15.9 Liters
*note - there is a typo in your question when you states P1 = 1 074 atm. I just assumed you meant 1.74, if this is a mistake just replace 1.74 with the real P1 and solve it as shown above
if you have any questions just comment them below

Define Acid and alkalis
Answer:
mark me brainliest
Explanation:
An acid is a substance that has a pH lower than 7. For example, hydrochloric acid, sulphuric acid, citric acid, ethanoic acid (vinegar). A base is a substance that neutralises an acid – those that dissolve in water are called alkalis. An alkali is a soluble substance with a pH higher than 7.
Answer:
The chemical which give hydrogen ion when dissolve in water is called acid.for example:HCL,HNO3,H2SO4 etc.
The bases that dissolve in water and produce hydroxyl ions are called alkalis.for example:NaOH,KOH etc.

1.00 mole of an ideal gas occupies a volume of 22.4 L at 0 C and 760 mmHg (STP). It is cooled to -41 C while the pressure is increased to 805 mmHg. What is the new volume of the gas in liters?
Answer:
[tex]V_2=18.0L[/tex]
Explanation:
Hello there!
In this case, according to the given information, we infer that we need the combined gas law in order to solve this problem:
[tex]\frac{P_2V_2}{T_2}} =\frac{P_1V_1}{T_1}}[/tex]
Thus, by suing the temperatures in Kelvins, we can solve for the final volume as shown below:
[tex]V_2 =\frac{P_1V_1T_2}{T_1P_2}}\\\\V_2 =\frac{(760mmHg)(22.4L)(232K)}{(273K)(805mmHg)} \\\\V_2=18.0L[/tex]

beta-plus decay sodium protons and neutrons
Answer:
(β-decay) is a type of radioactive decay in which a beta particle (fast energetic electron or positron) is emitted from an atomic nucleus, transforming the original nuclide to an isobar of that nuclide. For example, beta decay of a neutron transforms it into a proton by the emission of an electron accompanied by an antineutrino; or, conversely a proton is converted into a neutron by the emission of a positron with a neutrino in so-called positron emission.
Explanation:
Answer:
Beta decay occurs when, in a nucleus with too many protons or too many neutrons, one of the protons or neutrons is transformed into the other. ... In beta plus decay, a proton decays into a neutron, a positron, and a neutrino: p Æ n + e+ +n.

A 50,000 g septic tank reading reports that methane gas bubbles are present with a concentration of 17 ppm
Answer:
[tex]m_{solute}=0.85g[/tex]
Explanation:
Hello there!
In this case, according to the given information for the parts per million of methane in this solution, it is possible for us to first write the equation for this unit of concentration as shown below:
[tex]ppm=\frac{m_{solute}}{m_{solvent}} *1x10^6[/tex]
In such a way, since the septic tank has a mass of 50,000 g, the mass of methane into it is calculated as shown below:
[tex]m_{solute}=\frac{ppm*m_{solvent}}{1x10^6}[/tex]
Now, we plug in the numbers to obtain:
[tex]m_{solute}=\frac{17*50000g}{1x10^6}\\\\m_{solute}=0.85g[/tex]

Answer:
Acid/String Electrolyte
Explanation:
Litmus paper turning red means it is an acidic solution. A pH of more than 7 is Base while pH of less than 7 is an acid. Since the pH is 2, less than 7, it s is an acid. Since it has a high electrical conductivity, it must be a strong Electrolyte.

The resulting pressure was 930 mmHg carbon dioxide had a partial pressure of .70 atm and oxygen had a partial pressure of 680 mmHg. What is the partial pressure of nitrogen in kPa
Answer:
26.2kPa is the partial pressure of nitrogen
Explanation:
Assuming the partial pressure of Carbon dioxide is 0.070atm
The total pressure of a mixture of 3 gases (CO2, O2 and N2) is:
Total pressure = Partial pressure CO2 + Partial pressure O2 + Partial pressure N2
0.070atm CO2 are:
0.070atm * (760mmHg / 1atm) 53.2mmHg
Replacing:
930mmHg = 53.2mmHg + 680mmHg + Partial pressure N2
Partial Pressure N2 = 196.8mmHg
In kPa -101.325kPa = 760mmHg-
196.8mmHg * (101.325kPa / 760mmHg) =
26.2kPa is the partial pressure of nitrogenWhat is a decay series?
