natita [175]

Answer: 44.37 degrees C

Explanation:

Use combined gas law: (P1)(V1)/T1=(P2)(V2)/T2

For most gas laws, you  must convert to Kelvin:

K=deg C+273

K=25+273=298 K

Plug and chug:

(1.0 atm)(1.2 L)/(298 K)=(0.71 atm)(1.8 L)/(x)

Solve for x and get 317.37 K

Subtract 273 from this to convert to degrees Celsius. You will get 44.37 degrees Celsius.

7. When solid carbon reacts with oxygen gas to produce carbon dioxide gas, woul the triangle H value be on the reactant or produ
garik1379 [7]

When solid carbon reacts with oxygen gas to produce carbon dioxide gas. the deltaH (enthalpy change ) value is negative .DeltaH would be on the product side of the equation.

<h3>What is enthalpy change? </h3>

In a thermodynamic system, energy is measured by enthalpy. Enthalpy is a measure of a system's overall heat content and is equal to the system's internal energy plus the sum of its volume and pressure.

Knowing whether q is endothermic or exothermic allows one to characterise the relationship between q and H. An endothermic reaction is one that absorbs heat and demonstrates that heat from the environment is used in the reaction, hence q>0 (positive). For the aforementioned equation, under constant pressure and temperature, if q is positive, then H will also be positive. In a similar manner, heat is transferred to the environment when it is released during an exothermic reaction. Thus, q=0 (negative). Therefore, if q is negative, H will also be negative.

Determine the rate law and the value of k for the following reaction using the data provided.NO2(g) + O3(g) → NO3(g) + O2(g)[NO2
Anton [14]

Answer:

Rate = 43 M⁻¹s⁻¹[NO₂][O₃]

Explanation:

We need to find the reaction order in

rate = (NO₂ )ᵃ (O₃ )ᵇ

given:

( NO₂ ) M                ( O₃ )   M         Rate  M/s

  0.10                        0.33                1.420                (1)

  0.10                        0.66               2.840                (2)

  0.25                       0.66                7.10                   (3)

When keeping the NO₂ concentration constant in the first two while  doubling the concentration of O₃ , the rate doubles. Therefore it is first order with respect to O₃

Comparing (2) and (3) increasing   the concentration of NO₂ by a factor of 2.5  and  keeping  O₃ constant  , increased the rate by  a factor of 2.5. Therefore the rate is first order with respect to NO₂

Then rate law is

= k (NO₂) (O₃ )

To find k take any of the three and substitute the values to find k:

1.420 M/s = k (0.10)M x (0.33)M ⇒ k = 43 /Ms

Then the answer is Rate = 43 M⁻¹s⁻¹[NO₂][O₃]

What is the molarity of 50.84 g of Na2CO3 dissolved in 0.400 L solution?
borishaifa [10]

Answer:

1.20 M

Explanation:

Convert grams of Na₂CO₃ to moles.  (50.84 g)/(105.99 g/mol) = 0.4797 mol

Molarity is (moles of solute)/(liters of solvent) = (0.4797 mol)/(0.400 L) = 1.20 M
