Answer : The average kinetic energy is,
Explanation :
The formula for average kinetic energy is:
where,
k = Boltzmann’s constant =
T = temperature =
Now put all the given values in the above average kinetic energy formula, we get:
Therefore, the average kinetic energy is,
Answer: 3.61 L
Explanation:
To calculate the moles, we use the equation:
2 moles of produce = 3 moles of
0.1 moles of produce = moles of
According to the ideal gas equation:'
P = Pressure of the gas = 1 atm (NTP)
V= Volume of the gas = ?
T= Temperature of the gas = 20°C = (20+273) K = 293 K (NTP)
R= Value of gas constant in in kilopascals = 0.0821 Latm/K mol
Thus volume of oxygen at NTP obtained by decomposing 12.26 g of is 3.61 L
<span>A student conducted an experiment to test the effect of the digestive enzyme pepsin on cooked egg white and potato in the presence of hydrochloric acid at a pH of 1. The most probable inference would be: . Pepsin digests potato because it mainly contains starch. Therefore, the answer would be letter B.</span>
