Answer: Option (a) is the correct answer.

Explanation:

Photosynthesis is defined as a chemical process in which plants tend to make their own food in the presence of sunlight, water and carbon dioxide.

During this process, product formed by the plants is glucose and oxygen.

The chemical reaction equation for photosynthesis is as follows.

$6CO_{2} + 6H_{2}O + \text{Sunlight} \rightarrow C_{6}H_{12}O_{6} + 6O_{2}$

Therefore, we can conclude that out of the given options the correct equation is as follows.

$\text{water + carbon dioxide + sunlight} \rightarrow \text{oxygen + glucose}$

Answer:

Unmeltedd ice = 308.109 g

Explanation:

Gibbs Free energy:

A systems Gibbs Free Energy is defined as the free energy of the product of the absolute temperature and the entropy change less than the enthalpy change.

Therefore, G = ΔH-TΔS

where G is Gibbs Free Energy

ΔH is enthalpy change

T is absolute temperature

ΔS is entropy change

Here since there is a phase change, therefore G will be 0.

∴ΔH = TΔS

Given: Temperature, T = 0°C = 273 K

Entropy change,ΔS = 600 J/K

Latent heat of fusion of water = 333 J/g

∴ΔH = TΔS

∴ΔH = 273 x 600

= 163800 J

So this is the amount of enthalpy that will be used into melting of ice.

∴ΔH = mass of ice melted x latent heat of fusion of water

Mass of ice melted = ΔH / latent heat of fusion of water

= 163800 / 333

= 491.891 g

This is the mass of ice melted.

And initial amount of ice is 800 g

Amount of ice left after melting = Initial amount of ice - amount of ice melted

= 800-491.891

= 308.109 g

Amount of ice remained after melting = 308.109 g

Where does the engery of an earthquake originate

From convection of magma under the earths crust makes the plates slowly move and as they move over time they build up potential energy from the different plates grinding against each other and after so long the plates will lose there grip on each other and release the potential energy they've been building up for so long as kinetic energy causing what you know as an earthquake hope this helps please give brainliest
