Answer:

Explanation:

Photosystems are generally involved in photosynthesis, they assist in carrying out basic photochemistry (absorption of light and transfer of energy) during photosynthesis.

Photosystem I (or PSI) produces high energy compounds; ATP and NADPH from light energy absorbed during the light reactions of photosynthesis in algae, plants and some bacteria.

Photosystem II is the first membrane protein complex in organisms that produce oxygen. This oxygen oxidizes two molecules of water (in the presence of light) to produce molecular oxygen.

ATP,O2 and NADPH are the products. H2O,NADP,ADP and Pi are the reactants. acts as an electron carrier between the cytochrome b6f and photosystem 1 (PS1) complexes in the photosynthetic electron-transfer chain.

Photosystem II (or water-plastoquinone oxidoreductase) is the first protein complex in the light-dependent reactions of oxygenic photosynthesis. It is located in the thylakoid membrane of plants, algae, and cyanobacteria.

(b) Why is the heat of sublimation ( ΔH fus ) of a substance greater than its ( ΔHvap ) ?

Ivanshal [37]

This is because solids have less energy than liquids do, hence it takes more energy to excite a solid into its gaseous phase than it does a liquid.

When opposed to merely reducing their separation, from solid to liquid, the energy needed to totally separate the molecules as they move from liquid to gas is substantially higher. The latent heat of vaporization is therefore bigger than the latent heat of fusion for this reason.

<h3>What is heat of sublimation?</h3>

The amount of energy required to change one mole of a substance from its solid to its gaseous state under particular conditions—typically the standard ones—is known as the enthalpy of sublimation or heat of sublimation (STP). A solid's worth is based on its cohesive energy.

<h3>What is heat of vaporization?</h3>

The term "enthalpy of vaporization," which is often referred to as "heat of vaporization" or "heat of evaporation," refers to the amount of energy that must be applied to a liquid substance in order to cause a part of that substance to transform into a gas. Vaporization's enthalpy varies with the pressure at which the transition takes place.

73.5 mol of P4O10 contains how many moles of P ? moles of P:

Sholpan [36]

Answer:

294 moles of P

Explanation:

For every 1 mol of P4O10 contains 4 mol of P

so;

73.5 mol P4O10 × 4 mol P

1 mol P4O10

= 73.5 × 4

= 294 moles of P

Energy pyramid worksheet

Taya2010 [7]

Answer:

From top to bottom coyote, crow, squirrel, then acorn

Explanation:

The coyote has the least amount of energy and its the biggest predator so it belongs at the top. The crows eat squirrels and the squirrels eat acorns.

How does the automatic hammer convert gravitational potential energy into kinetic energy?

Nutka1998 [239]

Answer:

Exolaiend in explanation section

Explanation:

First of all, the automatic hammer is used to drive nails into tight spaces where where we can't get a sufficient striking force if we are to use a normal regular hammer in driving the nail.

So the nail to be driven is lifted out of rest(it's position). The energy here is gravitational potential energy.

Now, when it is driven into the tight spaces, the gravitational energy would be converted to kinetic energy due to the motion and speed involved.
