What process is represented by this redox equation ? 6H 2 O+6CO 2 C 6 H 12 O 6 +6O 2

Physics

Answer:

C. Photosynthesis

Explanation:

The redox reaction given in this question is given as follows:

6H2O + 6CO2 → C6H12O6 + 6O2

In this reaction, water (H2O) reacts with carbon dioxide (CO2) to form glucose (C6H12O6) and oxygen (O2). This is the general equation for PHOTOSYNTHESIS process, which is the process whereby plants manufacture their food (sugar) by combining water and carbon dioxide.

In the equation above, water is oxidized into oxygen, while carbon dioxide is reduced into glucose. This makes it an oxidation-reduction (redox) reaction.

Which of the following has the largest momentum?
san4es73 [151]

Momentum = mass x velocity

Thus Option A is the correct answer

Momentum (dog)  = 10 kg x (0.447 x 30) m/s

= 134.1 Kg m/s

Momentum ( bullet)  = 0.02 kg x (0.447 x 800) m/s

= 7.152 Kg m/s

Momentum ( truck) = 0, as v = 0

tightrope has both low mass  and low speed, thus its momentum will be low

An insulated rigid tank contains 3 kg of H2O in the form of a saturated mixture of liquid and vapor at a pressure of 150 kPa and
Andre45 [30]

Answer:

change in entropy is 1.44 kJ/ K

Explanation:

from steam tables

At 150 kPa

specific volume

Vf = 0.001053 m^3/kg

vg = 1.1594 m^3/kg

specific entropy values are

Sf = 1.4337 kJ/kg K

Sfg = 5.789 kJ/kg

initial specific volume is calculated as

v_1 = vf + x(vg - vf)

      = 0.001053 + 0.25(1.1594 - 0.001053)

v_1 = 0.20964  m^3/kg

s_1 = Sf + x(Sfg)

     = 1.4337 + 0.25 \times 5.7894 = 2.88 kJ/kg K

FROM STEAM Table

at 200 kPa

specific volume

Vf = 0.001061 m^3/kg

vg = 0.88578 m^3/kg

specific entropy values are

Sf = 1.5302 kJ/kg K

Sfg = 5.5698 kJ/kg

constant volume  sov_1 -  v_2  = 0.29064 m^3/kg

v_2 = v_1 = vf + x(vg - vf)

       =0.29064 = x_2(0.88578 - 0.001061)

x_2 = 0.327

s_2 = 1.5302 + 0.32 \times 5.5968 = 3.36035 kJ/kg K

Change in entropy \Delta s = m(s_2 - s_1)

              =3( 3.36035 - 2.88) =  1.44 kJ/kg
