You will use the formula PV=nRT
P = pressure
V = volume
n = moles
R = gas constant
T = Temperature
Since 21.4g of Ar (Argon) is given this will be divided by the molar mass of Ar to give you the number of moles. Mass of Ar is 40g so
21.4g/40g = 0.54 moles of Argon
Then you just change Celsius to Kelvin by adding 273 to 12.5 which will be
12.5 + 273 = 285.5 K
(The formula for changing C to K is
X°C + 273 = K)
Now with moles and temperature in K you can plug all your values into PV=nRT to find volume so
(1.25atm)V = (0.54moles)(0.0821)(285.5K)
(0.0821 is the gas constant R when using atm, Liters, moles, and kelvin; this should always be given by your teacher)
Multiply
1.25v= 12.66
Divide 1.25 on both sides
V= 12.66/1.25 —> 10.13L
Your answer should be approximately 10.13L
Answer:
λ = 0.002 nm
The given photon is either x-ray or gamma ray because the range of x-ray and gamma ray is 1 nm-0.1 pm.
Explanation:
Given data:
Energy of photon = 1.10 × 10⁻¹³ J.
Wavelength of photon = ?
Solution:
Formula:
E = h.c / λ
λ = h. c / E
λ = 6.626 × 10⁻³⁴ j. s × 3×10⁸ m/s / 1.10 × 10⁻¹³ J.
λ = 19.878 × 10⁻²⁶m / 1.10 × 10⁻¹³ J
λ = 18.071 × 10⁻¹³ m
λ = 18.071 × 10⁻¹³ × 10⁹
λ = 18.071 × 10⁻⁴ nm
λ = 0.002 nm
The given photon is either x-ray or gamma ray because the range of x-ray and gamma ray is 1 nm-0.1 pm.
According to Arrhenius Theory of acids and bases, an Arrhenius base produces OH-.
Among the four options, (3) LiOH is the correct one because it can separate into Li+ and OH- when being put in water.

Bond formation is the way in which atoms interact to form compounds.
<h3>What is bond formation?</h3>
Bond formation is the way in which atoms interact to form compounds. The following are the kind of bonds formed by the atoms;
C and AI - ionic bond
N and P - covalent bond
N and O - covalent bond
The bonds in each of the lattices are;
CuO - ionic bond
Hg - metallic bond
P2O5 - covalent bond
P - covalent bond
CaCl2 - ionic bond
The following is a depiction of the processes shown;
Na0 →Na+1 - oxidation
P0→P+5 - oxidation
AI+3 → AI0 - reduction
The balanced reaction equations are;
2H2O + F2 → 2HF + O2
SO2 + 3H2 → H2S + 2H2O
2H2SO4 + C → 2SO2+CO2+2H2O

Answer:
sodium hydroxide
Explanation:
When sodium is dropped in cold water, it reacts explosively and burns with a golden yellow flame. The reaction is exothermic and vigourus. It form sodium hydroxide with the liberation of hydrogen gas.
