A flask filled with oxygen is heated from 5 degrees Celsius to 30 degrees Celsius. The starting pressure was 50 kPa, what is the

final pressure? (Be sure to convert from Celsius to Kelvin, add 273 to your Celsius temperature to get the temperature to kelvin. Ex. 0 degrees Celsius id equal to 273 kelvin)

54.5kPa

Explanation:

Given parameters:

T₂ = 30°C = 30+273 = 303K

T₁ =  5°C = 5+273 = 278K

P₁ = 50kPa

Unknown:

P₂ = ?

Solution:

We can solve this problem using the combined gas law simplification and assuming that volume is constant as seen from the container:

            \frac{P_{1} }{T_{1} } =  \frac{P_{2} }{T_{2} }

Making the unknown the subject of the formula:

            P₂ = \frac{P_{1} T_{2} }{T_{1} }

             P₂ = \frac{50 x 303}{278} = 54.5kPa

What is the volume of an irregular object if the initial volume in the graduated cylinder is 3.50 ml and it rises to 7.50 ml aft
Margarita [4]
Answer is: the volume of an irregular object is 4,00 ml.
<span>Volume is the amount of space the object occupies and can be finded immersing it in water in a container with volume markings and than see how much the level of the container changes (goes up). 
</span>V(irregular object) = V(final volume) - V(initial volume).
V(irregular object) = 7,50 ml - 3,50 ml.
V(irregular object) = 4,00 ml.

Baking soda (NaHCO3) can be added to a fruit mix solution to create a carbonated drink. An example is the reaction between bakin
DanielleElmas [232]

Answer:

74.4 ml

Explanation:

          C₆H₈O₇(aq) + 3NaHCO₃(s) => Na₃C₆H₅O₃(aq + 3CO₂(g) + 3H₂O(l)

Given     15g = 15g/84g/mol = 0.1786mole Sodium Bicarbonate

From equation stoichiometry 3moles NaHCO₃ is needed for each mole citric acid or, moles of citric acid needed is 1/3 of moles sodium bicarbonate used.

Therefore, for complete reaction of 0.1786 mole NaHCO₃ one would need 1/3 of 0.1786 mole citric acid or 0.0595 mole H-citrate.

The question is now what volume of 0.8M H-citrate solution would contain 0.0595mole of the H-citrate? This can be determined from the equation defining molarity. That is => Molarity = moles solute / Liters of solution

=> Volume (Liters) = moles citric acid / Molarity of citric acid solution

=> Volume needed in liters = 0.0.0595 mole/0.80M = 0.0744 Liters or 74.4 ml

QUESTION 7
Temka [501]

The student's test average is : 0.92

Total score obtained = 369

Number of tests = 4

Since Each test is exactly 100 points ;

The total score obtainable is (100 × 4) = 400

Average = score obtained / total score obtainable

Average = 369 / 400

Average = 0.9225

Average = 0.92
