Answer:

34g

Explanation:

We'll begin by writing the balanced equation for the reaction. This is illustrated below:

H2S + 2AgNO3 —> 2HNO3 + Ag2S

Next, we shall determine the number of mole of H2S required to react with 2 moles of AgNO3.

This is illustrated below:

From the balanced equation above,

We can see that 1 mole of H2S is required to react completely with 2 moles of AgNO3.

Finally, we shall convert 1 mole of H2S to grams. This is shown below:

Number of mole H2S = 1 mole

Molar mass of H2S = (2x1) + 32 = 34g/mol

Mass = number of mole x molar Mass

Mass of H2S = 1 x 34

Mass of H2S = 34g

Therefore, 34g of H2S is needed to react with 2 moles of AgNO3.

At what condition to sodium chloride and silver nitrate react

Mumz [18]

They give a double displacement reaction where the ions switch places and give sodium nitrate (NaNO3) and silver chloride (AgCl) as the products. Silver nitrate is also very soluble in water, but silver chloride is highly insoluble in water and will precipitate out of solution as a white solid.

A thermometer with a percent error of 6.5% reads the room temperature as 68°F. what is the actual temperature in the room ?

Lynna [10]

Answer:

Actual temperature for the given temperature with thermometer with error of 6.5% is 63.8 degrees.

Explanation:

The percentage error in thermometer is 6.5% this means that if the temperature is 100 degrees the thermometer shell show 106.5 degrees. now calculating the actual temperature of the thermometer when the given temperature is 68°

Applying unitary method for solution 106.5

Then 100 will be $\frac {68}{106.5} \times 100$

= $0.6384 \times 100$

= 63.8 Degrees

On solving the value of this equation will give the actual temperature as 63.8 Degrees .

What energy change occurs during condensation? Please answer, i’ll give you brainliest !

kupik [55]

Answer:

Please see Explanation and Attachment (Heating Curve for Water)

Explanation:

Energy change associated with phase change in substances is either endothermic (energy added to system) or exothermic (energy removed from system). Condensation is but one term in six (6) describing phase change occurring when energy change is involved. The following table, in general, summarizes the related effects of energy change as applied to phase change.

Process Phase Change Energy Change*

Condensation gas => liquid Exothermic

Evaporation liquid => gas Endothermic

Freezing liquid => solid Exothermic

Melting solid => liquid Endothermic

Sublimation solid => gas Endothermic

Deposition gas => solid Exothermic

_____________________

* Energy Change terms:

Endothermic => Addition of heat energy

Exothermic => Removal of heat energy
