To complete the balancing of the following combustion reaction, we must do elemental balances. For C, there is 5 on the left side hence there should be 5 CO2. For H, H20 should be 9/2. Next we balance O. on theright side we find a total of 29/2. So the o2 on the left side should be 29/4. To  have whole number stoich.coeff. we multiply the numbers by 4, hence answer is
4C5H9O + 9O2= 20 O2 + 18 H20.

A sample of 0.010 mole of oxygen gas is confined at 127 °c and 0.80 atmosphere. what would be the pressure of this sample at 27
devlian [24]
First,let's assume ideal gas behavior for simplicity. This is a special case because the volumes of the two states are equal. At constant volume, we can use the Gay-Lussac equation:

P₁/T₁ = P₂/T₂

(0.8)/(127+273) = (P₂)/(27+273)
Solving for P₂,
P₂ = 0.6 atm

<em>Thus, the answer is 0.6 atm.</em>

What is the pressure in arm exerted by 2.48 miles of gas in 250.0 mL container at 58
konstantin123 [22]

Answer:

T = 58 + 273.15 = 331.15

R = 0.082 atm

V = 250.0 mL / 1000 = 0.25 L

P =  n x R x T / V

P = 2.48 x 0.082 x 331.15 / 0.25

P = 67.342 / 0.25

P = 269.368 atm

6kg of coal (carbon) is burned in air. What mass of carbon dioxide will be produced? (Assume that combustion is complete and ign
Flauer [41]

The mass of carbon dioxide that would be produced will be 22 kg

<h3>Combustion of carbon</h3>

The combustion of carbon in air can be represented by the equation:

C + O2 ---> CO2

The mole ratio of C to O2 to CO2 is 1:1:1.

Mole of 6kg of carbon = mass/molar mass

                                      = 6000/12

                                      = 500 moles

Equivalent mole of CO2 produced = 500 moles

Mass of 500 moles CO2 = mole x molar mass

                                          = 500 x 44.01

                                           = 22,005 g or 22 kg approximately

Calculate the energy required to move from solid water at 0 degrees C to liquid water at 0 degrees C
Serhud [2]

Answer:

Q = 334\,kJ

Explanation:

Let assume that 1 kilogram of water in solid state at one atmosphere of pressure. The fussion latent heat of 334\,\frac{kJ}{kg}, the heat required to change the phase of water is:

Q = m \cdot L_{f}

Q = (1\,kg)\cdot \left(334\,\frac{kJ}{kg} \right)

Q = 334\,kJ
