Answer:

Heat required to melt 42 g if ice is 13,860 J

Explanation:

The amount of heat required to melt  grams of water at 0°C is given as follows;

The mass of the ice (water), m = 42 g

The latent heat of fusion of ice ΔH_f= 330 J/g

Therefore, heat required to melt 42 grams is given as follows;

Heat required to melt ice = Mass of the ice, m × The specific latent heat of fusion of the ice, ΔH_f

Heat required to melt 42 g if ice = m × ΔH_f = 42 g × 330 J/g = 13,860 J

Heat required to melt 42 g if ice = 13,860 J.

Mice21 [21]

Ecologists use food web diagrams as tools in their studies of different populations of organisms within an ecosystem because it shows the feeding relationship between organisms in the ecosystem.

<h3>What is a Food web?</h3>

This is defined as the graphical representation of the feeding relationship which occurs between organisms in the ecosystem and helps to predict the outcome in the addition or removal of a species.

The food web also helps to determine the various ways in which energy flows and it usually starts from the producers which are the plants as a result of their photosynthetic ability which involves the conversion of solar energy to chemical energy.

There are various organisms in the ecosystem and the food web helps to provide a better understanding of their feeding habits and impact various factors will result in.

What do the individual spheres represent in the model!
Trava [24]

Answer:

the individual atom in the molecule

Explanation:

In chemistry, the ball-and-stick model is a molecular model of a chemical substance.  Invidual spheres there represent atoms in the molecule. The bigger atomic number the atom has, the larger diameter of the spheres this atom has in this model.

I hope this answer will help you. Have a nice day !
