Adhesion is the attraction of molecules of one kind for molecules of a different kind... water is adhesive because the water molecules are attracted to the straw and therefore adhere to it. Thus, adhesive forces are important for sustaining life. This is because of these forces, water can flow up from the roots to the tops of plants to feed the plant, allowing it to move against gravity through plant cells. Another example of why its important that water is adhesive is the movement of water to the tops of trees and the drainage of tears from tear ducts in the corners of your eyes. Or how water droplets stick to the end of the pine needles. These are all examples of adhesion.

Nitrogen monoxide, NO, is formed in automobile exhaust by the reaction of nitrogen and oxygen in the air: N2 (g) + O2 (g) ↔ NO (

Solnce55 [7]

Answer:

The equilibrium concentration of NO is 0.001335 M

Explanation:

Step 1: Data given

The equilibrium constant Kc is 0.0025 at 2127 °C

An equilibrium mixture contains 0.023M N2 and 0.031 M O2,

Step 2: The balanced equation

N2(g) + O2(g) ↔ 2NO(g)

Step 3: Concentration at the equilibrium

[N2] = 0.023 M

[O2] = 0.031 M

Kc = 0.0025 = [NO]² / [N2][O2]

Kc = 0.0025 = [NO]² / (0.023)(0.031)

[NO] = 0.001335 M

The equilibrium concentration of NO is 0.001335 M

Why is it important to conserve or save our energy resources?

earnstyle [38]

answer:

reducing energy use limits the number of carbon emissions in the environment
conserving energy produces a higher quality of life. Reduced emissions result in cleaner air quality
it helps create a healthier planet, or at least helps sustain the resources we already have

Based on the ideal gas law, there is a simple equivalency that exists between the amount of gas and the volume it occupies. at s

nordsb [41]

2.10 grams. The balanced equation for the reaction is CO + 2H2 ==> CH3OH The key thing to take from this equation is that it takes 2 hydrogen molecules per carbon monoxide molecule for this reaction. And since we've been given an equal number of molecules for each reactant, the limiting reactant will be hydrogen. We can effectively claim that we have 5.86/2 = 2.93 l of hydrogen and an excess of CO to consume all of the hydrogen. So the number of moles of hydrogen gas we have is: 2.93 l / 22.4 l/mol = 0.130803571 mol And since it takes 2 moles of hydrogen gas to make 1 mole of methanol, divide by 2, getting. 0.130803571 mol / 2 = 0.065401786 mol Now we just need to multiply the number of moles of methanol by its molar mass. First lookup the atomic weights involved. Atomic weight carbon = 12.0107 g/mol Atomic weight hydrogen = 1.00794 g/mol Atomic weight oxygen = 15.999 g/mol Molar mass CH3OH = 12.0107 + 4 * 1.00794 + 15.999 = 32.04146 g/mol So the mass produced is 32.04146 g/mol * 0.065401786 mol = 2.095568701 g And of course, properly round the answer to 3 significant digits, giving 2.10 grams.

Gases are measured in different units. Which of the following measurements of pressure are equal? Select all that apply.

viva [34]

Explanation:

Pressure of a gas is the combined force with which the molecules bombard a unit area of the wall of the container.

1 atm = 760mmHg

= 760torr

= 101325Pa

= 101325Nm⁻²

1mmHg = 1torr

1Pa = 1Nm⁻²

101.325 kPa and 101,325 Pa are the same

1000Pa = 1kPa

101,325 Pa and 1 atm

1atm and 101.325 kPa
