What is the equilibrium constant of a reaction

1 answer:

4 0

Homogeneous Reactions. At equilibrium, the rate of the forward and reverse reaction are equal, which is demonstrated by the arrows. The equilibrium constant, however, gives the ratio of the units (pressure or concentration) of the products to the reactants when the reaction is at equilibrium.

When steam condenses into water, __________. When steam condenses into water, __________. heat is given off by the water no heat

lys-0071 [83]

Answer: heat is given off by the water

Explanation:

Condensation can be defined as the process by which water vapors or steam in the atmosphere are converted into liquid water. It is the part of water cycle. The water form water bodies and terrestrial surfaces gets evaporated in the form of water vapors. These vapors rise in the upper atmospheric layers and aggregate to form the clouds when these vapors become heavy they fall down in the form of rain. Heat is given off in this process by the water vapors or steam to be converted in liquid.

Water is a good solvent when A) the solute is hydrophobic. B) the solute is nonpolar. C) the solute is polar. D) the solvent is

pochemuha

the answer is C. the solute polar water itself is a polar solvent so it combines well with other polar solvents (which basically have polar molecules)

An aqueous solution of calcium hydroxide is standardized by titration with a 0.112 M solution of hydrobromic acid. If 15.2 mL of

TiliK225 [7]

Answer:

0.0457 M

Explanation:

The reaction that takes place is:

2HBr + Ca(OH)₂ → CaBr₂ + 2H₂O

First we calculate how many moles of acid reacted, using the HBr solution's concentration and volume:

Molarity = Moles / Volume

Molarity * Volume = Moles

0.112 M * 12.4 mL = 1.389 mmol HBr

Now we convert HBr moles to Ca(OH)₂ moles, using the stoichiometric ratio:

1.389 mmol HBr * $\frac{1mmolCa(OH)_{2}}{2mmolHBr}$ = 0.6944 mmol Ca(OH)₂

Finally we calculate the molarity of the Ca(OH)₂ solution, using the given volume and calculated moles:

0.6944 mmol Ca(OH)₂ / 15.2 mL = 0.0457 M
