At what pressure will 4.80 moles of fluorine gas have a volume of 60.0 liters and a temperature of 298 K?
The pressure of the given mol of fluorine as an ideal gas at the given temperature and volume is 1.96atm.
Ideal Gas LawThe Ideal gas law or general gas equation emphasizes on the state or behavior of a hypothetical ideal gas. It states that "the pressure multiplied by volume is equal to moles multiply by the universal gas constant multiply by temperature.
It is expressed as;
PV = nRT
Where P is pressure, V is volume, n is the amount of substance, T is temperature and R is the ideal gas constant ( 0.08206 Latm/molK )
Given the data in the question;
Amount of fluorine gas n = 4.80molesVolume V = 60.0LTemperature T = 298KPressure P = ?To determine the pressure of the fluorine gas, we substitute our values into the expression above.
PV = nRT
P = nRT / V
P = ( 4.80mol × 0.08206Latm/molK × 298K ) / 60.0L
P = 117.378624Latm / 60.0L
P = 1.96atm
Therefore, the pressure of the given mol of fluorine as an ideal gas at the given temperature and volume is 1.96atm.

37L of carbon dioxide decomposes. what mass of carbon results?
PLEASE HELP <3
The mass of carbon that resulted from the decomposition of 37 L of carbon dioxide is 19.8 g
Balanced equationCO₂ —> C + O₂
From the balanced equation above,
1 L of CO₂ decomposed to produce 1 L of C.
Therefore,
37 L of CO₂ will also decompose to produce 37 L of C
How to determine mass of CarbonAt standard temperature and pressure (STP),
22.4 L = 1 mole of C
Therefore,
37 L = 37 / 22.4
37 L = 1.65 mole of C
Thus, the mass of Carbon can be obtained as follow:
Mole of C = 1.65 mole Molar mass of C = 12 g/mol Mass of C =?Mass = mole × molar mass
Mass of C = 1.65 × 12
Mass of C = 19.8 g
Thus, 19.8 g of carbon were obtained from the reaction.

How does an indicator differentiate between an acid and base?
Changes solubility
Changes reactivity
Changes color
Changes size
Answer:
that is all I know sorry hope that may help you :)
Explanation:
Indicator is a substance which shows different colors in acidic and basic medium. Indicators can be natural (derived from natural sources) or artificial ( man-made) for example :
*Litmus is an indicator. Acid turns blue litmus into red while base turns red litmus into blue
* Turmeric solution does not show change in color (remains yellow) in acidic solution and turns red in basic solution.
When CO2 and H2O react to form H2CO3, the number of bonds broken in H2O is ____ and in CO2 is _____. one; one
CO2 and H2O react to form H2CO3 and two bonds are broken each in CO and H2O to form H2CO3.
What is chemical bonding?Chemical bonding refers to the forces of attraction which hold atoms of the same or different elements together in order to form stable compounds or molecules .
Chemical bonding may be either ionic or covalent.
The greater the number of bonds in a compound, the more stable the compound.
During chemical reactions, bonds are broken and new binds are formed.
There are two bonds each in CO2 and H2O.

What is the wavelength of a photon with an energy of 4.56 x 10-19 J?
• A. 502 nm
• B. 436 nm
C. 688 nm
D. 460 nm
Answer:
B
Explanation:
We can use Planck's equation. Recall that:
[tex]\displaystyle E = h\nu[/tex]
Where h is Planck's constant and ν is the frequency.
We also have that:
[tex]\displaystyle \lambda \nu = c[/tex]
Where c is the speed of light and λ is the wavelength. Hence:
[tex]\displaystyle \nu = \frac{c}{\lambda}[/tex]
Therefore:
[tex]\displaystyle E= h\left(\frac{c}{\lambda}\right)[/tex]
Solving for λ yields:
[tex]\displaystyle \lambda = \frac{hc}{E}[/tex]
Hence substitute. Recall that h = 6.626 × 10⁻³⁴ Js and c = 2.998 × 10⁸ m/s:
[tex]\displaystyle \begin{aligned} \lambda & = \frac{(6.626\times 10^{-34}\text{ Js})(2.998\times 10^8\text{ m/s})}{4.56\times 10^{-19} \text{ J}} \left(\frac{1\times 10^9\text{ nm}}{1\text{ m}}\right) \\ \\ & = 436\text{ nm}\end{aligned}[/tex]

What is the pH of a solution formed when 100 ML of an acid with a pH of two is diluted 1 L with pure water
Answer: look down hope I helped
Explanation:
1) First convert to pOH as OH is the dissociating species in a base equilibrium.pH + pOH = 14 (at 25 C)pH=13, hence pOH = 1,Hence [OH] = 10^-1 Mdiluting by factor of 10 with pure water gives [OH] = 10^-2 MThe new pOH = 2, hence the new pH is 12In general, dilution (with pure water) by a factor of 10 moves the pH 1 unit in the direction of the pH of water (pH 7). i.e. it moves up for acids, down for bases.(At infinite dilution of either acids or bases, you’d have pure water - obvious when you think of it like that)
