Answer:

The relative humidity is low

Explanation:

The higher the dew point rises, the greater the amount of moisture in the air. The lower the humidity, the lower the dew point. The dew point is low and thus water cannot exist in liquid state but as a gas.

Determine the molarity of a solution prepared by dissolving 0.198 g of "KHP" (C8H5O4K) in enough water to make 125 mL of solutio
rosijanka [135]

Answer:

0.007756M KHP; 0.0009695 moles NaOH reacts; 0.03488M NaOH.

Explanation:

Potassium hydrogen phthalate, KHP, is a salt used as standard to determine concentration of basic solutions as NaOH solutions.

To find molarity of the KHP solution we need to convert mass of KHP to moles and divide this in 125mL = 0.125L:

<em>Moles KHP -Molar mass: 204.22g/mol-:</em>

0.198g * (1mol / 204.22g) = 0.0009695 moles KHP

<em>Molarity:</em>

0.0009695 moles KHP / 0.125L = 0.007756M KHP

NaOH reacts with KHP as follows:

NaOH + KHP → Na⁺ + KP⁻ + H₂O

That means 1 mole of NaOH reacts per mole of KHP, that means moles of NaOH that reacts are = Moles of KHP added:

0.0009695 moles NaOH reacts

In 27.80mL = 0.02780L the NaOH was contained. Molarity is:

0.0009695 moles NaOH / 0.02780L =

0.03488M NaOH

Use the following equation to determine how many moles of C are needed to react with 0.500 mole of SO2.
Maru [420]

Answer:

The answer to your question is 1.25 moles of C

Explanation:

Reaction

                                5C  +  2SO₂   ⇒   CS₂  +  4CO

Check that the reaction is balanced

                          Reactant         Element        Product

                                5                   C                   5

                                2                    S                    2

                                4                   O                    4

Use proportions to find the moles of C needed.

                       5 moles of C -----------------  2 moles of SO₂

                       x  moles of C ----------------   0.500 moles of SO₂

                       x = (0.500 x 5) / 2

                       x = 1.25 moles of C

When HSO4- disassociates in water, it is a reversible reaction. Is it correct to say that \"in this reaction HSO4- disassociates
SVETLANKA909090 [29]
When an ion <span>HSO4- disassociates in water, the dissociated ions are H+ and SO4-. When you balance the equation, it is composed of one mole of each dissociated ions. Hence it is correct to say that HSO4- dissociates into H+ and SO4-. Answer is correct.</span>
