D = m / V
D = 2790 g / 205 mL
D = 13.60 g/mL
Answer:
radio waves
Explanation:
On the far left of the diagram are radio waves, which include microwaves. They have the longest wavelengths and lowest frequencies of all electromagnetic waves. They also have the least amount of energy.
Answer:
2117.02 litres
Explanation:
Using the ideal gas equation as follows;
PV = nRT
Where:
P = pressure of the gas (atm)
V = volume of the gas (L)
n = number of moles (mol)
R = gas law constant (Latm/molK)
T = temperature (K)
According to the information given in this question,
P = 0.12 atm
V = ?
n = 9.7moles
T = 46°C = 46 + 273 = 319K
R = 0.0821 Latm/molK
Using PV = nRT
0.12 × V = 9.7 × 0.0821 × 319
0.12V = 254.04
V = 254.04 ÷ 0.12
V = 2117.02 litres
Answer:
Reaction equilibrium will shift to the left (higher molar volume side of process).
Explanation:
For gas phase reactions, changes in pressure-volume conditions cause a stress on the process equilibrium shifting away from the applied pressure-volume change.
LeChatlier's Principle states for a gas phase reaction at equilibrium ...
if the pressure is increased (volume decreased) the reaction will shift toward the lower molar volume side of the process.
if the pressure is decreased (volume increased) the reaction will shift toward the higher molar volume side of the process.
if the sum of molar volumes of reactants equals the sum of molar volumes of products, changes in pressure-volume conditions will NOT affect the equilibrium stability. Example => H₂(g) + Cl₂(g) ⇄ 2HCl(g) will not be affected by P-V changes as ∑Vm(reactants) = ∑Vm(products).
Charle's law states that, v1 / t1 = v2 / t2 .
<span>Hence,v(volume) is directly proportional to t(temperature). </span>
<span>Thus, the volume decreases.</span>
