The reaction N2O4↽−−⇀2NO2 is allowed to reach equilibrium in a chloroform solution at 25 ∘C . The equilibrium concentrations are 0.371 mol/L N2O4 and 2.04 mol/L NO2 . Calculate the equilibrium constant, Kc , for this reaction. study equilibrium the effect of anxiety (low vs. high) and stress (low vs. moderate vs. high) on test.

Everyone experiences anxiety occasionally, but persistent anxiety can reduce your quality of life. Though likely best known for altering behavior, worry can have negative effects on our physical health. Anxiety speeds up our heartbeat and breathing, concentrating blood flow to the parts of our brains that need it. You are getting ready for a challenging situation by having this extremely bodily reaction. Test equilibrium may be impacted by anxiety. According to studies, pupils with low levels of test anxiety perform better on multiple-choice question (MCQ) exams than pupils with high levels of anxiety. Studies have equilibrium that female students have greater levels of test anxiety than male students.

How many microliters are in 7.4 x 10^-61 centimeters?
schepotkina [342]

Answer:

Microliters = 7.4\times 10^{-58}

Explanation:

SI unit of volume is liter.

1 dm^{3}=1 liter ..............................(1)

1dm=10cm

1dm^{3} = 1000 cm^{3}.................(2)

replacing value of 1 dm^{3}from equation (1) in equation (2)

1 liter = 1000 cm^{3}...................(3)

but

1 liter = 10^{6} microliters....................(4)

replacing value of 1 liter from equation (3) in equation (4)

1000 cm^{3} = 10^{6} microliters

on solving further ,we get

1 cm^{3} = \frac{10^{6}}{10^{3}}microliter

1 cm^{3} = 1000 microliter

7.4\times 10^{-61}\times 1000

Microliters = 7.4\times 10^{-58}

A drum used to transport crude oil has a volume of 162 L. How many grams of water, as steam, are required to fill the drum at 1.
Paraphin [41]

Answer:

114.48g

Explanation:

Step 1:

Data obtained from the question:

Volume (V) = 162 L

Pressure (P) = 1.20 atm

Temperature = 100°C = 100°C+ 273 = 373K

Number of mole (n) of H2O =?

Recall:

Gas constant (R) = 0.082atm.L/Kmol

Step 2:

Determination of the number of mole of H2O i.e steam.

Using the ideal gas equation, the number of mole of H2O can be obtained as follow:

PV = nRT

1.2x 162 = n x 0.082 x 373

Divide both side by 0.082 x 373

n = (1.2x 162) /(0.082 x 373)

n = 6.36 moles

Step 3:

Determination of mass of H2O i.e steam:

This is illustrated below:

Molar Mass of H2O = (2x1) + 16 = 2 + 16 = 18g/mol

Number of mole H2O = 6.36 moles

Mass of H2O =?

Mass = number of mole x molar Mass

Mass of H2O = 6.36 x 18

Mass of H2O = 114.48g

Therefore, the mass of H2O i.e steam required to fill the drum of crude oil is 114.48g
