Answer:

pressure of the oxygen gas is 7.88atm

Explanation:

Moles of oxygen in cylinder  =  2.80 mol

volume=8.58L

temperature=294K

molar gas constant(R)= 0.0821 L atm / (mol K)

The pressure is calculated using ideal gas law:

PV = nRT

making Pressure subject of the formula

P = nRT /V

  = 2.80× 0.0821 ×294  /8.58 L

P = 7.88 atm

Answer:

7.88 atm

Explanation:

This question is a very straight forward Question, we have given almost all the parameters needed to solve the question. The parameters given in the question are: Number of moles of oxygen gas = 2.80 mol, the volume of the cylinder= 8.58 L, pressure of the 02 = ???( not given) and the gas temperature = 294 K.

We are going to use the formula for the ideal gas law below to solve this question:

PV = nRT.

Where P = pressure, V = volume , n= number of moles, R= gas constant and T= temperature.

nRT/ V= P.

P= 2.80 × 0.0821 × 294/ 8.58.

P= 67.58472÷ 8.58.

P= 7.87700699300699300.

P= 7.88 atm.

the burning of wood is a chemical reaction between cellulose molecules in the wood and oxygen the products are carbon dioxide an
Sati [7]

Put the <em>wood and excess oxygen in a closed contai</em>ner that contains some device that can create a spark (to start the reaction).

Determine the <em>mass of container + contents</em>.

<em>Start the reaction</em> and, after everything has cooled down, again determine the <em>mass of container + contents</em>.

If the two masses are the same, you have demonstrated that the reaction obeys the Law of Conservation of Mass.

Balance the equation <br><br> __C7H6O2 + __O2 —&gt; __CO2 + __H2O
ser-zykov [4K]

2 C₇H₆O₂ + 15 O₂ → 14 CO₂ + 6 H₂O

<u>Explanation:</u>

C₇H₆O₂ + O₂ → CO₂ + H₂O

First we have to balance the O- atoms, we have to put 6 in front of water so there are 12 H atoms on RHS, to balance it we need to put 2 in front of  C₇H₆O₂, and so we have 14 C - atoms on LHS, 28 + 6 = 34 O - atoms on RHS, so we have to put 15 in front of Oxygen in LHS, so that each and every atom in the equation gets balanced now. The balanced equation is,  2 C₇H₆O₂ + 15 O₂ → 14 CO₂ + 6 H₂O

Most metamorphosis processes take place
Ugo [173]

Most metamorphic processes take place a few kilometers below Earth's surface. Metamorphic processes result due to intense heat and high pressure below the Earth's surface. Also, metamorphism can occur on two scales, contact and regional.
