What is the equilibrium constant for the reaction?

Chemistry
1 answer:
sp2606 [1]2 years ago
7 0

Answer: C. 20

Explanation: One equation for the equilibrium constant is \frac{[Products]}{[Reactants]}. The products are typically on the left side and the reactants on the right.

Given this and the values of each, we can easily plug this in. However, we must multiply the products instead of adding them.

\frac{0.69M*0.98M}{0.034M} =19.888, or 20M

19.888 can be easily rounded to 20, meaning that C is the best answer.

I hope this helps! Pls mark brainliest!! :)

Question 19 (3 points)
dalvyx [7]

Answer:

c ) 29.4 psi

Explanation:

If the density of earth was twice than its actual density which is 5.51 g/mL, then at sea level the atmospheric pressure of earth in British units would be equal to 29.4 psi because increase of gravity, increase occurs in the atmospheric pressure.  If we double the gravity of earth by double of the earth density, so the weight of that same mass of air will be double which leads to the doubling of the atmospheric pressure at the sea level.

How many grams are in 0.5 moles C6H12O6?<br><br><br><br> Show work please!
Nitella [24]
Molar mass of C6H12O6 = 6x12 + 12x1 + 6x16 = 180g

SO mass of 1 mole of C6H12O6 = 180g

mass of 0.5 mole of C6H12O6 = 0.5 x180g = 90g

Enter a chemical equation for HI(aq) showing how it is an acid or a base according to the Arrhenius definition. Consider that st
jek_recluse [69]

Answer:

HI (aq) → H⁺ (aq) +  I⁻ (aq)

HI (aq) +  H₂O(l)  → H₃O⁺ (aq) +  I⁻ (aq)

Explanation:

The Arrhenius acid concept indicates that a substance behaves like acid if it produces hydrogen ions H⁺ or hydronium ions H₃O⁺ in water. A substance will be classified as a base if it produces OH⁻  hydroxide ions in water. This way of defining acids and bases works well for aqueous solutions.

When we mix HI (aq) and water, we are increasing [H₃O⁺]

HI (aq) → H⁺ (aq) +  I⁻ (aq)

HI (aq) +  H₂O(l)  → H₃O⁺ (aq) +  I⁻ (aq)
