The new volume will be 33.5 L.
Explanation:
The kinetic theory of gases confirm that the volume occupied by gas molecules will be directly proportional to the temperature of the molecules and inversely proportional to the pressure of the molecules. We can consider the moles to be n = 1. Then, the equation for the gases will be
PV = nRT
Here, P is the pressure, V is the volume, R is the gas constant and T is the temperature.
So, P = 523 Torr, T = 7.50 °C = 7.50+273.15 = 280.65 K and the gas constant R = 62.363 Torr L mol⁻¹K⁻¹.
Thus, the new volume will be 33.5 L.
Hund's Rule<span>. </span>Hund's rule<span>: every orbital in a subshell is singly occupied with one electron before any one orbital is doubly occupied, and all electrons in singly occupied orbitals have the same spin. so D. is the answer</span>
Answer:
Titration curves for strong and weak acids illustrating the proper choice of acid-base indicator. Any of the three indicators will exhibit a reasonably sharp color change at the equivalence point of the strong acid titration, but only phenolphthalein is suitable for use in the weak acid titration.
Explanation:
Molar mass (formula, molecular mass) is the mass of one mole of a chemical element or a chemical compound. Molar mass is suitable and often used in chemistry because it allows for a light conversion between stoichiometric (molar) relationships represented by a chemical equation and mass relations, which are more significant in practice.
The molar mass of a compound is obtained by the sum of the atomic weights of the atoms which form a compound.
So, formula mass of P4 is:
M(P4) = 4 x Ar(P) = 4 x 31 = 124 g/mole
Answer:
The explanation is given below:
Explanation:
As we know that the volume is inversely proportional to the volume. If the pressure is rising from 1 atm to 3 atm so the volume of the ballon would decrease
P_1V_1 = P_2V_2
1.0 × 2.5L = 3 × V_2
V_2 = 0.833L
Since the air is moving from high pressure to low pressure and the two ballons are interconnected via a long pipe so the movement of the air is from bottom to top
