Answer:
The new equilibrium total pressure will be increased to one-half to initial total pressure.
Explanation:
From the information given :
The equation of the reaction can be represented as;
From above equation:
2 moles of sulphur dioxide reacts with 1 mole of oxygen (i.e 2 moles +1 mole =3 moles ) to give 2 moles of sulphur trioxide
So; suppose the volume of this system is compressed to one-half its initial volume and then equilibrium is reestablished.
So if this process takes place ; the equilibrium will definitely shift to the side with fewer moles , thus the equilibrium will shift to the right. As such; there is increase in pressure.
Let the total pressure at the initial equilibrium be 
and the total pressure at the final equilibrium be 
According to Boyle's Law; Boyle's Law states that the pressure of a fixed mass of gas is inversely proportional to the volume, provided the temperature remains constant.
Thus;
P ∝ 1/V
P = K/V
PV = K
where K = constant
So;
PV = constant
Hence;
From the foregoing; since the volume is decreased to one- half to initial Volume; then ,
also;
Thus ;
Dividing both sides by 
From ;
Thus; The new equilibrium total pressure will be increased to one-half to initial total pressure.
Answer:
<h2>500 J</h2>
Explanation:
The kinetic energy of an object can be found by using the formula
where
m is the mass
v is the velocity
From the question
m = 1.6 kg
v = 25 m/s
We have
We have the final answer as
<h3>500 J </h3>
Hope this helps you
Answer:
There are 1.287 grams of acetylene collected
Explanation:
Total gas pressure = 909 mmHg
Vapor pressure of water = 20.7 mmHg
Pressure of acetylene = 909 mmHg - 20.7 mmHg = 888.3 mmHg
1mmHg = 1 torr
22 ° C + 273.15 = 295.15 Kelvin
Ideal gas law ⇒ pV = nRT
⇒ with p = pressure of the gas in atm
⇒ with V = volume of the gas in L
⇒ with n = amount of substance of gas ( in moles)
⇒ with R = gas constant, equal to the product of the Boltzmann constant and the Avogadro constant (62.36 L * Torr *K^−1 *mol^−1)
⇒ with T = absolute temperature of the gas (in Kelvin)
888.3 torr * 1.024 L = n * 62.36 L * Torr *K^−1 *mol^−1 * 295.15 K
n = 0.04942 moles of C2H2
Mass of C2H2 = 0.04942 moles x 26.04 g/mole = 1.287 g
There are 1.287 grams of acetylene collected
Answer:
A three-carbon chain has a straight line extending from the center carbon.
Explanation:
Isomers are compounds having the same molecular formula but different structural formulas.
Butane and 2-methylpropane are constitutional isomers. Constitutional isomers differ in the way that the constituent atoms are connected to each other.
Butane is a straight chain compound while the compound 2-methylpropane consists of a three-carbon chain which has a straight line extending from the center carbon.
