Mn(s) + Cu(NO₃)₂(aq) → Mn(NO3)2 + Cu

Manganese added with Copper(II) nitrate gives the product manganese nitrate and copper.

What is redox reaction ?

Redox reactions include a change in the oxidation state of the substrate. Loss of electrons or a rise in an element's oxidation state are both considered to be oxidation. Gaining electrons or lowering an object's or its atoms' oxidation state are both considered reductions. Combination, decomposition, displacement, and combustion reactions are the most frequent oxidation-reduction (redox) processes.

H2 + F2 = 2HF is the basic example of a redox reaction. Where hydrogen peroxide added with fluorine to form 2 molecule of hydrogen fluoride.

The reaction of hydrogen and iodine to produce hydrogen iodide has a Kc of 54.3 at 703 K. Given the initial concentrations of H2

pentagon [3]

Answer:

[HI] = 0.7126 M

Explanation:

Step 1: Data given

Kc = 54.3

Temperature = 703 K

Initial concentration of H2 and I2 = 0.453 M

Step 2: the balanced equation

H2 + I2 ⇆ 2HI

Step 3: The initial concentration

[H2] = 0.453 M

[I2] = 0.453 M

[HI] = 0 M

Step 4: The concentration at equilibrium

[H2] = 0.453 - X

[I2] = 0.453 - X

[HI] = 2X

Step 5: Calculate Kc

Kc = [Hi]² / [H2][I2]

54.3 = 4x² / (0.453 - X(0.453-X)

X = 0.3563

[H2] = 0.453 - 0.3563 = 0.0967 M

[I2] = 0.453 - 0.3563 = 0.0967 M

[HI] = 2X = 2*0.3563 = 0.7126 M

Calculate the mass of 0. 4 moles of water.

Anna [14]

Answer:

7.208 g

Explanation:

0.4mol x $\frac{2(1.01) + 16.00 g}{1 mol}$

= 7.208 g

You are using molar mass of H20 to find the mass. Moles of 0.4 and 1 mol cancel out leaving you with just grams. You get the values in the numerator from the periodic table and the 2(1.01) is because you have 2 of the H in H20
