Explanation:

A water molecule contains two hydrogen atoms bonded with an oxygen atom. That is, formula of water is $H_{2}O$ .

Since there is high difference in electronegativity of both hydrogen and oxygen. Thus, there will be uneven distribution of charge on a water molecule as hydrogen will have a positive charge whereas oxygen will have a negative charge.

This will also make the water molecule polar in nature.

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.

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.

Calculate the specific heat of a piece of wood if 2000 g of wood absorbs 75,250 J of heat, and its temperature changes from 30°C

inna [77]

Answer:

Explanation:

The specific heat capacity=quantity of heat in joule/mass×change in temperature

from this question the quantity of heat is 75250,the mass is 2000 and the change in temperature is 50-30

which is 20

therefore

c=75250/2000×20

c=75250/40000

c=1.88

I hope this helps

NH3 1. Lewis Structure 2. Perspective drawing 3. Number of atoms bonded to central atom 4. Number of non-bonding electron pairs

Stels [109]

This question will be answered in parts:

<h3>1. Lewis Structure</h3>

There are three N-H bonds and one lone pair on the nitrogen atom in the Lewis structure of NH3. On hydrogen atoms, there are no lone pairs that can only hold two electrons.

The lewis structure is as shown in the diagram.

<h3>2. Perspective Drawing</h3>

A molecule is shown from a viewpoint with its atoms' bonds pointing either in your direction (bolded wedge) or away from you (hash wedge).

The perspective drawing of NH3 is given here

<h3>3.Number of atoms bonded to central atom </h3>

Nitrogen is the central atom in the Lewis structure of NH3, which also contains one lone pair and is bound to the three hydrogen atoms.

<h3>4.Number of non-bonding electron pairs on the central atom</h3>

Three bond pairs and two lone pairings exist. This is due to the fact that nitrogen contains five electrons in its outer shell, three of which are bound to hydrogen atoms and two of which are free.

<h3>5. Electronic geometry:</h3>

The electronic geometry of nitrogen is based on a tetrahedral arrangement of electron pairs, and ammonia likewise possesses four electron pairs. There is only one lone pair because there are only three connected groupings. But since the lone pairs are "invisible," the ammonia has a pyramidal form.

<h3>6. Molecular geometry with ideal bond angles</h3>

The molecular geometry of ammonia it has a trigonal pyramidal or distorted tetrahedral structure.

The bond angle in ammonia is less than the standard 109.5⁰. The bond angle is 107⁰

<h3>7.Hybridization of central atom</h3>

The core nitrogen (N) atom in the NH3 molecule has a steric number of (3 + 1) = 4, which causes Sp3 hybridization.

<h3>8. Polarity:</h3>

Because of its asymmetrical form, a trigonal pyramidal structure, and the different electronegativities of N(3.04) and H(2.2), the NH3 (ammonia) molecule is polar in nature .
