Explanation:
At what temperature will 2.50 moles of ideal
gas produce a pressure of 25.0 atm in a 10.0 L
container
Answer: 1,218K
Explanation:
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]

Chemical symbols stand for?
Answer Explanation:
If it is like H, or O or N or Na or Cl, those are the elements. Those are on the Periodic table. pH is the acidity and basicity of a substance, how acidic or basic(caustic) it is. mol is Moles. kPa is kilopascals. STP is standard temperature and pressure, at 0*C(Celsius), or 273.15 K(Kelvin), and 101,325 pascals, or 101.325 kilopascals.
Avagadro's Number is 6.022x10^23, the number of atoms in a mole. The Ideal Gas Law is P(Pressure in kPa) times V(Volume in L, liters) equals n(number of moles of gas) times R(the universal gas constant, or 8.3145 (L kPa/K mol) or 8.3145 liters kilopascals per Kelvin mole. that is just a few of them.

Which refers to solid ice that condenses and forms on surfaces like grass or windows?
dew
frost
hail
sleet
Frost refers to solid ice that condenses and forms on surfaces like grass or windows.
WHAT IS FROST?Frost refers to a deposit of small white ice crystals formed on solid surfaces when the temperature falls below freezing temperature.
Frost forms when the temperature of the atmosphere is below freezing i.e. < 0°C.
Therefore, frost refers to solid ice that condenses and forms on surfaces like grass or windows.

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.

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

a(n)
Base/Strong Electrolyte
Acid/Weak Electrolyte
Acid/Strong Electrolyte
Base/Weak Electrolyte

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.
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]

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.
