Answer:

The answer is "At 2200K, NO(g)'s partial pressure is below 2500K. C.KP by a factor of (RT) is lower than Kc"

Explanation:

In the given question choices were missing so, the correct choice can be defined as follows:

Given:

Reaction equation: \bold{N_2(g) + O_2(g) \longrightarrow 2NO(g)}

when temperature 2,200 K the value of KP = 1.1 \times 10^{-3}

when temperature 2,500 K the value of KP = 3.6 \times 10^{-3}

value of kp=?

KP= \frac{(PNO)^2}{(PN_2)(PO_2)}

In the above formula the value of (PN_2) and (PO_2) is defined in the denominator section and the value of (PNO) is defined in the numerator section that defines the value of KP is increases.so, the temperature of the KP will be KP ∝ (PNO).

Estimate the ph of the resulting solution prepared by mixing 1.0 mole of solid disodium phosphate (na2hpo4) and 1.25 mole of hyd
GenaCL600 [577]

The HCl added = 1.25 moles

and the moles of Na2HPO4 = 1 mole

Now when acid is added in the given solution of Na2HPO4

One mole of H+ will react with one mole of Na2HPO4 to given one mole of NaH2PO4

Na2HPO4  + H+  ---> NaH2PO4

Now this one mole formed NaH2PO4 will further react with 0.25 moles of H+ left to form 0.25 moles of  H3PO4 and 0.75 moles of NaH2PO4 will remain in the solution

So this will result into formation of a buffer of phosphoric acid and NaH2PO4

NaH2PO4  + H+  ---> H3PO4

pKa of H3PO4 = 2.1

so pH = pKa + log [salt] / [acid] = 2.1 + log [0.75 / 0.25] = 2.58

so the pH will be in between 2.1 to 7.2

According to each substances heat of fusion, which of the items below requires more heat to be added per gram of substance to go
alexira [117]

<u>Answer: </u>The correct answer is Silver.

<u>Explanation:</u>

Specific heat of fusion is defined as the amount of heat which is required to raise the temperature of 1 gram of a substance to 1°C. It is generally expressed in kJ/mol

We are required to find the substance which require more heat. For that we need to know the specific heat of all the substances.

The substance which have the highest specific heat, will require more heat.

The specific heat of the given substances are:

Silver = 11.3 kJ/mol

Sulfur = 1.7175 kJ/mol

Water = 5.98 kJ/mol

Lead = 4.799 kJ/mol

The specific heat of silver is the highest and hence, will require more heat.

Hence, the correct answer is silver.

kenny6666 [7]

Charcoal with a carbon-14 activity of 0.60 compared to new wood has less than 5,730 years.

<h3>What is a radioactive isotope?</h3>

A radioactive isotope is an element in nature that emit radioactivity in a given period of time (e.g., the half-life for C14 is equal to 5,730 years).

Radioactive dating is a technique to measure the age of an element by measuring its radioactive activity.

In conclusion, charcoal with a carbon-14 activity of 0.60 compared to new wood has less than 5,730 yr.
