The answer is Keq= .0891

Answer:

0.0891

Explanation:

Keq is the equilibrium constant.

Keq= products/ reactants

Let’s take a chemical reaction:

aA -> bB

Keq = \frac{[B]^b}{[A]^a}

Equilibrium constant is the ratio of the molar concentration of the products to the molar concentration of the reactants. The coefficients are raised to the power of the respective molar concentrations.  

The balanced reaction is:

2NO + Br₂ → 2NOBr

Keq = \frac{[NOBr]^2}{[NO] [Br2]} = \frac{(0.0474)^2}{(0.312)^2(0.259)} 

       = 0.0891

Describe how the Sun and Earth formed.
melamori03 [73]

Answer:

When the solar system settled into its current layout about 4.5 billion years ago, Earth formed when gravity pulled swirling gas and dust in to become the third planet from the Sun. Like its fellow terrestrial planets, Earth has a central core, a rocky mantle and a solid crust.

Balancing chemical equations
kolbaska11 [484]

Answer:

2B2 + 3O2 → 2B2O3

Explanation:

Balance The Equation: B2 + O2 = B2O3

1. Label Each Compound With a Variable

  aB2 + bO2 = cB2O3

2. Create a System of Equations, One Per Element

  B: 2a + 0b = 2c

  O: 0a + 2b = 3c

3. Solve For All Variables (using substitution, gauss elimination, or a calculator)

  a = 2

  b = 3

  c = 2

4. Substitute Coefficients and Verify Result

  2B2 + 3O2 = 2B2O3

      L R

  B: 4 4 ✔️

  O: 6 6 ✔️

hope this helps!
