Answer: 7s
Explanation:
The order of the reaction is 2.
Integrated rate law for second order kinetic is determined using the formula
1/[At]=1/[Ao] +kt
But, [Ao] is the initial concentration = 1.50 mol/L
And [At] is the final concentration = 1/3 of initial concentration =1/3×1.5 = 0.5 mol/L
Rate constant, k = 0.2 L/mol*s
Using the formula
1/0.5=1/1.5+0.2t
Collecting like terms
1/0.5-1/1.5=0.2t
LCM = 1.5
3-1/1.5=0.2t
2/1.5=0.2t
Multiply both sides by 1/0.2
2/1.5×0.2=t
2/0.3=t
t=6.66s
t=7s
Answer:1.
Explanation: This reaction is catalyzes by pyruvate dehydrogenase. Pyruvate being the end product of glycolysis has many fates after glycolysis,one of which is to enter the TCA(Tricarboxylic acid cycle) cycle. It is first converted to actetate by the action of pyruvate dehydrogenase. This enzyme converts pyruvate to acetate releasing CO2 and NADH because this oxidative decarboxylation of pyruvate is coupled with reduction of NAD+ which can feed into the electron transport chain.
Assuming that the combustion formula is
CH4 + 2O2 --> 2H2O + CO2<span>,
That means for every 1 molecule of methane(CH4) there will be one molecule of carbon dioxide(</span>CO2) produced. Methane molecular weight 16, carbon dioxide molecular weight is 44. Then the percent yield should be:
1 * (0.374/ 16) /(0.983/44)= 0.374*44/ 0.983 * 16= 104.6%
You sure the number is correct? Percent yield should not exceed 100%

Hello there!
In this case, according to the given chemical reaction, it is possible for us to realize that the 46.2 kJ of energy are given per mole of reaction, which are related to 3 moles of hydrogen; Thus, we can calculate the energy per mole of hydrogen as shown below:
Now, to calculate the total energy, we convert the grams to moles of hydrogen as shown below:
Best regards!
Answer:
One way in which the rocks are formed on Mount Moran is due to the presence of intense heat and pressure. When the slabs of sedimentary rocks got buried deep beneath the Earth's surface, they have experienced intense heat and pressure. Later on, they formed into metamorphic rocks.
