Answer:
5.77 L
Solution:
Data Given:
Moles = n = 0.24 mol
Temperature = T = 35 °C + 273 = 308 K
Pressure = P = 1.05 atm
Volume = V = ?
Formula Used:
Let's assume that the hydrogen gas in balloon is acting as an Ideal gas, the according to Ideal Gas Equation,
P V = n R T
where; R = Universal Gas Constant = 0.082057 atm.L.mol⁻¹.K⁻¹
Solving Equation for V,
V = n R T / P
Putting Values,
V = (0.24 mol × 0.082057 atm.L.mol⁻¹.K⁻¹ × 308 K) ÷ 1.05 atm
V = 5.77 L
Sodium 23 has 11 electrons 11 protons and 12 neutrons
Answer:
radio waves are the sound waves that are produces by a radio
Explanation:
Density = Mass / Volume
10.5 = 500 / x
10.5x = 500
x = 50 cm^3 (1 sig fig) volume of the sphere
Volume of a sphere = 4/3 pi r^2
pi = 3.14 r = radius
50 = 4/3 pi r^3
50•3/4 = pi r^3
37.5 = pi r^3
37.5/pi = r^3
11.9 = r^3
cube root(11.9) = r
2.3 = r
Diameter = 2•radius
Diameter = 2 • 2.3
Diameter = 5 cm (1 sig fig) diameter
Answer:
A. the law of constant composition
Explanation:
The molecules in the container would have the same composition because they would have traded around atoms until an equilibrium was reached with every molecule having 1 Hydrogen and 1 Chlorine.
