Answer:
111 L
Explanation:
Calculation of moles of hydrogen gas:-
Mass of = 18.6 g
Molar mass of = 2.01588 g/mol
According to the given reaction:-
2 moles of hydrogen gas on reaction produces one mole of acetic acid gas.
So,
1 mole of hydrogen gas on reaction produces mole of acetic acid gas.
Also,
9.23 mole of hydrogen gas on reaction produces mole of acetic acid gas.
Moles of acetic acid gas = 4.615 moles
Given that:
Temperature = 35 °C
The conversion of T( °C) to T(K) is shown below:
T(K) = T( °C) + 273.15
So,
T = (35 + 273.15) K = 308.15 K
n = 4.615 moles
P = 1.05 atm
V = ?
Using ideal gas equation as:
where,
P is the pressure
V is the volume
n is the number of moles
T is the temperature
R is Gas constant having value = 0.0821 L atm/ K mol
Applying the equation as:
1.05 atm × V = 4.615 moles ×0.0821 L atm/ K mol × 308.15 K
<u>⇒V = 111 L</u>
Metamorphic rocks were once sedimentary, igneous or even other metamorphic rocks that have been changed by heat and pressure. so i think this will help you.
Answer:
Three ways that waves may interact with matter are reflection, refraction, and diffraction. Reflection occurs when waves bounce back from a surface that they cannot pass through. Refraction occurs when waves bend as they enter a new medium at an angle and start traveling at a different speed.
Explanation:
Answer:
1. The salt bridge completes the circuit of the voltaic cell to allow the flow of current
2. The porous divider performs the function of a salt bridge, hence a salt bridge is unnecessary in a single-beaker voltaic cell
Explanation:
1. The oxidation and reduction half cells of a voltaic cell are connected by the salt bridge in other to ensure that the internal circuit is electrically neutral, to avoid the rapid reaction to reach equilibrium conditions which affects results in preventing voltage drop in the voltaic cell.
The salt bridge also aids in charge accumulation
2. In a single-beaker voltaic cell with the compartments separated by a porous divider, the function of the porous divider is the same as that of the salt bridge, hence the salt bridge is unnecessary.
