write chemical equations of photosynthesis and cellular respiration and show if carbon is oxidized or reduced

Chemistry
1 answer:
irina [24]2 years ago
6 0

Answer:

Explanation:

  • The chemical reaction for cellular respiration  is as follows -

C₆H₁₂O₆ ( Glucose ) + 6 O₂ ( Oxygen ) --------------> 6CO₂  ( Carbon dioxide ) +  6H₂O ( Water ) + 38 ATP molecules ( Energy ) .

This is an example of oxidation of carbon .

  • The chemical reaction for photosynthesis  is as follows -

6CO₂  ( Carbon dioxide ) + 6H₂O ( Water ) --------------> C₆H₁₂O₆( Glucose ) + 6 O₂  ( Oxygen ).

This is an example of reduction of carbon .

Define cohesion. Describe how the cohesive property of water is useful for living organisms.
kolbaska11 [484]

Answer:cohesion is the action or fact of forming a united whole.

Water is very cohesive in that it "sticks" to itself. Cohesion is what allows a water droplet to form, for example. When water molecules surround one another, they settle toward a low energy state. ... Adhesion and cohesion are water properties that affect living and non-living things on earth through water molecules.

_________ heat is the amount of heat required to change the temperature of 1 gram of a substance by 1 degree Celsius​
Vlada [557]

Answer:

<u>Specific heat capacity</u> is the amount of heat required to change the temperature of 1 gram of a substance by 1 degree Celsius​

Explanation:

Specific heat capacity:

It is the amount of heat required to raise the temperature of one gram of substance by one degree.

Formula:

Q = m.c. ΔT

Q = amount of heat absorbed or released

m = mass of given substance

c = specific heat capacity of substance

ΔT = change in temperature

The substances with higher value of specific heat capacity require more heat to raise the temperature by one degree as compared the substances having low value of specific heat capacity.For example,

The specific heat capacity of oil is 1.57 j/g. K and for water is 4.18 j/g.K. So, water take a time to increase its temperature by one degree by absorbing more heat while oil will heat up faster by absorbing less amount of heat.

Consider that both oil and water have same mass of 5g and change in temperature is 15 K. Thus amount of heat thy absorbed to raise the temperature is,

For oil:

Q = m.c. ΔT

Q = 5 g× 1.67 j/g K × 15 K

Q = 125.25 j

For water:

Q = m.c. ΔT

Q = 5 g× 4.18 j/g K × 15 K

Q = 313.5 j

we can observe that water require more heat which is 313.5 j to increase its temperature.
