How does the heat content of the reaction change in the process of photosynthesis when a glucose molecule is formed?

patriot [66]3 years ago

In the process of photosynthesis, when a glucose molecule is formed, THE HEAT CONTENT OF THE REACTION INCREASES, THUS, THE VALUE OF Q IS POSITIVE.

There are two types of chemical reaction, these are exothermic and endothermic reaction. Exothermic reactions are those reactions that gives off heat when they are occurring while endothermic reactions are those reactions that absorb heat from their environment during the course of reaction. Photosynthesis is an endothermic reactions; it absorbs energy from the environment when it is occurring, thus, the heat content of the product is always more than that of the reactants. The heat content of compounds are represented by letter q. For photosynthesis, q is positive, because there is an increase in the heat content of the product [glucose] formed.

g All of the molecules below have polar bonds but only one of the molecules is a polar molecule. Which one is a polar molecule?
lbvjy [14]

Answer: NF_3

Explanation:

Geometrical symmetry of the molecule and the polarity of the bonds determine the polarity of the molecule.

The molecule that has zero dipole moment that means it is a geometrically symmetric molecule and the molecule which has some net dipole moment means it is a geometrically asymmetric molecule.

As the molecule is symmetric, the dipole moment will be zero as dipole moments cancel each other and the molecule will be non-polar.

As the molecule is asymmetric, the dipole moment will not be zero and the molecule will be polar.

Example: NF_3

Thus, we can say that NF_3 is a polar molecule.

Chlorine has two isotopes, 35Cl and 37Cl; 75.77 % of chlorine is 35Cl and 24.23 % is 37Cl. The atomic mass of 35Cl is 34.969 amu
storchak [24]

Answer:

35.4528731 amu

Explanation:

To appropriately get the atomic mass unit of chlorine, we can get the answer using the masses from the isotopes. This can be obtained as follows. What we do is that we multiply the percentage compositions by the masses.

Now let’s do this.

[75.77/100 * 34.969] + [24.23/100 * 36.966]

= 26.4960113 + 8.9568618 = 35.4528731

Physical Changes
Talja [164]
C. Physical changes do not change the identity of a substance, only the physical appearance such as shape or form. If you break a pencil in half, it is still composed of the same material and therefore keeps its identity as the substance it was before the physical change. Phase changes, such as ice melting, is also a physical change because it changes form. But ice is still made of H20 just like water and steam are comprised of H20.

During World War One, observation balloons were used in order to spy out enemy positions. An observation
blondinia [14]

Answer:

0.971

Explanation:

The pressure (P) in atmospheres (atm) the balloon was filled to will be

P = P1 +P2 + P3

where P1 is the pressure in atm of Helium (0.5 atm)

P2 is the pressure in atm of Nitrogen (X atm)

P3 is the pressure in atm of Hydrogen (0.4 atm)

The value of P2 provided in the question is in mmHg

To convert we have

1 atm = 760 mmHg

X atm = 54 mmHg

X = 54 × 1/760

X =  0.071 atm

Hence, P2 = 0.071 atm

Thus, from the formula earlier

P = 0.5 + 0.071 + 0.4

P = 0.971 atm
