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.

Based on the chemical equation, use the drop-down menu to choose the coefficients that will balance the chemical equation: ()bao2 ()h2so4 → ()h2o2 ()baso4
Based on the given chemical equation, the value of coefficient that is used in the reaction before each molecule is 1.
What is balanced equation?Balanced chemical equations are those equation in which each element is present in equal amount on both side of the chemical reaction.
Given chemical reaction is:
BaO₂ + H₂SO₄ → H₂O₂ + BaSO₄
Above reaction is balanced as all elements are present in equal amounts on both sides. So, the value of coefficients is 1.
Hence the required coefficients is 1.

Explanation:
While transferring naoh solution to the ph paper, you accidentally splash it onto your skin. check all actions you should take. tell your teacher right away. try to save the naoh for recycling purposes. neutralize by applying a small amount of acid (e.g., hcl). wipe the naoh with a paper towel and continue the experiment. rinse the exposed skin with water.
When NaOH solution is accidentally spilled on your skin while trying to transfer it into a pH paper, one should rinse the exposed skin with water.
How to deal with laboratory accidents?Chemical reagents can be found in the laboratory and are harmful to the human skin.
However, when transferring an alkaline solution of NaOH to the pH paper and one accidentally splashes it onto the skin, water should be poured to the affected part immediately.
The water washes away the chemical before it starts to have negative effect on the skin.

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)
identify the particles that facilitate the electric conductivity of sodium metal
Answer:
Sodium metal will conduct electricity in both a solid and liquid state, due to 'a sea' of delocalised electrons which can move and are able to carry charge
Sodium metal will conduct electricity only when it is in a liquid state or in solution because of the ionic state which are free to move in this state, allowing them to carry charge and conduct electricity.
What are free electrons ?An electron within a conducting substance (as in a Sodium metal) but not permanently attached to any atom.

Calculate the number of grams needed to make 250 mL of 0.150 M NaOH.
For solving such problems we need to know mole concept,
Here, Volume and Concentration is given so it's so easy to find number of moles. first we have to convert volume from ml to litre and and then multiply by the concentration of NaOH:
★ Volume of NaOH = 250ml = 250 × 10⁻³ = 0.25L
★ Concentration of NaOH = 0.15 mol/L
Now, let's find the number of moles:-
Number of moles = volume × concentration
Number of moles = 0.25*0.15
Number of moles = 0.0375 mol/L
Thereafter, we have to find molar weight of NaOH and for this we have to know atomic mass of these elements:-
Na = 22g
O = 16g
H = 2g
Substitute the value
Molar weight of NaOH = 22+16+2
= 40 g/mol
Mass of NaOH = no. of moles × molar weight
= 0.0375*40
= 1.5 g/mol
Hence, We need 1.5 g /mol to make NaOH.
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.

Increasing the concentration of a reactant shifts the position of chemical equilibrium towards formation of more products. What effect does adding a reactant have on the rates of the forward and reverse reactions?.
Answer:
A.There is no effect on the forward and reverse reactions. For an equilibrium reaction, the forward and reverse rates are always equal.
B. Both the forward and reverse reactions speed up by the same amount.
C. The forward reaction speeds up immediately. As more product is made, the reverse reaction starts to speed up as the forward reaction starts to slow down until they are equal.
D. The forward reaction slows down initially. As the reaction proceeds, the reverse reaction slows down to meet the new forward reaction.
E. The forward reaction speeds up. Eventually, production of the product speeds up the reverse reaction rate to match the new forward rate.
F. It is impossible to say without more specific information.
