Answer:

Option D. 17.5

Explanation:

Equiibrium is: CO + 2H₂  ⇄  CH₃OH

1 mol of CO is in equibrium with 2 moles of hydrogen in order to make, methanol.

Initially we have 0.42 moles of CO and 0.42 moles of H₂

If 0.29 moles of CO remained, (0.42 - 0.29) = 0.13 moles have reacted.

So in the equilibrium we may have:

0.29 moles of CO, and (0.42 - 0.13 . 2) = 0.16 moles of H₂

Ratio is 1:2, if 0.13 moles of CO haved reacted, (0.13 . 2) moles have reacted of hydrogen

Finally 0.13 moles of methanol, are found after the equilibrium reach the end.

Let's make expression for KC: [Methanol] / [CO] . [Hydrogen]²

0.13 / (0.29 . 0.16²)

Kc = 17.5

Partial charges will exist on each atom when a bond exists between two atoms with different electronegativities. Since the atom
lana66690 [7]

Answer:

negative, positive, increase

Explanation:

From the given question,  

During the formation of bond, between two atoms with difference between their electronegativity-

  • The more electronegative atom, will pull the electrons towards itself , and hence acquires a partial negative charge,

And,

  • The less electronegative atom, will acquire a partial positive charge.
  • The more the difference between the electronegativity of the atoms, the more would be the magnitude of partial charge.
  • And, the less would be the difference between the electronegativity of the atoms, the lesser would be the magnitude of partial charge.

In AG calculations, temperature is expressed in a. degrees Celsius. b. kelvins. c. degrees Fahrenheit, d. kilojoules.
schepotkina [342]

Answer:

The correct option is: a. degrees Celsius

Explanation:

The anion gap is the difference in the cations and anions in plasma, serum or urine, calculated from medical lab test results. It can be calculated by measuring the concentration of the anions or cations, which are expressed in millimoles/litre (mmol/L) or milliequivalents/liter (mEq/L).

The temperature in this test is expressed in degrees Celsius (°C).

2. To what volume will you have to dilute 20.0 ml of a 8 M HCl solution to make a 0.35 M
GrogVix [38]

Answer:

You need to dilute 8 M HCl to 0.35 M to make 457 mL.

Explanation:

Use the equation M₁V₁=M₂V₂

Convert the mL to L : 20 mL= 0.02 L

8 M x 0.02 L = 0.35 M x V₂

V₂ = 0.4571429 L = 457 mL
