A car engine has a displacement of 536 cubic inches (in^3). What is the engines displacement in nm^3? Use dimensional analysis and show all work
Answers
The engine displacement in cubic nanometer (nm³) is 8.785×10²⁴ nm³
Data obtained from the question Displacement in in³ = 536 in³Displacement in nm³ =? Conversion scale1 in³ = 1.639×10²² nm³
With the above convesion scale we can obtain the displacement in nm³
How to determine the displacement in nm³1 in³ = 1.639×10²² nm³
Therefore,
536 in³ = 536 × 1.639×10²²
536 in³ = 8.785×10²⁴ nm³
Thus, the displacement in nm³ is 8.785×10²⁴ nm³

What pressure is requred to contain 0.023 moles of nitrogen gas in a 4.2 L container at a
temperature of 20.°C?
Answers
Answer:
0.13 atm
Explanation:
Using the Ideal Gas Law; PV=nRT, we can rearrange to solve for pressure.
P=nRT/V
P is pressure, n is number of moles (0.023), R is a constant (0.08206 L*atm/mol*K), T is temperature in Kelvin (293.15K) and V is volume, 4.2 L.
So, plugging in;
P=(0.023mol)(0.08206L*atm/mol*K)(293.15K)/(4.2 L)
P=0.1317 atm
P=0.13 atm; multiply by 760 to get to Torr or mmHg.

An enzyme-catalyzed reaction is run, and its Vmax and KM value are recorded. An inhibitor is added at a concentration of 0.675 mM. The value for KM did not change between the two reactions. However, Vmax decreased by 70%.
a. Where does this inhibitor bind to the enzyme? Briefly explain.
b. What is the value of Ki for the inhibited reaction?
Answers
We have that the value of Ki for the inhibited reaction
The place the enzyme inhibitor binds solely to the complicated fashioned between the enzyme and the substrate.KI = 3.551mMChemical Reactiona)
Generally, if the fee of Vmax binds, the place the enzyme inhibitor binds solely to the complicated fashioned between the enzyme and the substrate.
b) V diminished through 70%
Thereofore
Alternate = 1 - 0.7 = 0.3V
Hence
0.3 =1/ ( 1 + [I]/KI)

Find the percent composition of water in barium chloride dihydrate. Round your answer to the
nearest whole number.
A)17%
B)8%
C)85.3%
Answers
The percent composition of water will be 15%
Percent compositionThe percent composition of a component of a compound is found by dividing the mass of the component by the mass of the compound.
In other words:
Percent composition = mass of component/mass of substance x 100
In this case, the formula for barium chloride dihydrate is [tex]BaCl_2.H_4O_2[/tex]
The molar mass of the compound is 244.26 g/mol
The molar mass of the water component is 18 x 2 = 36 g/mol
Thus, the percent composition of water in the compound can be found, such that:
Percent composition of water = 36/244.26 x 100
= 15% to the nearest whole number.

Why NH2 is a bad leaving Group?
Answers
Explanation:
Consider that strong bases are strong nucleophiles, and thus unstable with the negative charge associated with dissociation from the molecule. Hence, strong bases are generally very poor leaving groups, but can be converted into good leaving groups that are more stable with the associated negative charge.
