The deciduous forest supports a diverse ecology. A warm growing season with abundant moisture encourages plants to grow, and the ground is covered with small plants, flowers, ferns, and grasses. In spring the trees and shrubs produce new leaves and colorful flowers. In summer the tall trees cast shade on the forest floor, providing ideal growing conditions for shade-tolerant plants. Seeds and berries provide for plant reproduction, and feed small rodents and birds. The leaves that fall in the autumn provide plenty of material for decomposers, soil bacteria, worms, grubs, and fungi. All these plants together are the primary producers. If berries were destroyed and taken out of the food web, which organisms would be directly affected? *

Answer:

the answer is convalent bonds

Explanation:

Strong linkages—called covalent bonds—hold together the hydrogen (white) and oxygen (red) atoms of individual H2O molecules. Covalent bonds occur when two atoms—in this case oxygen and hydrogen—share electrons with each other.

Work is done when the arrow is released from the bow. When this work is not done, the bow is damaged.

We know that energy is neither created nor destroyed rather is converted from one form to another. When the string of the bow is pulled back the elastic potential energy does work and the arropow is released. The elastic potential energy is converted to the kinetic energy of the moving arrow.

However, when this work is not done, the whole energy in the string does work on the bow thereby damaging it.

When sodium acetate is dissolved in water, it is hydrolyzed into ions.

When a salt of weak acid or base is dissolved in water, this salt hydrolysis in it. Water ionises into hydroxide and hydrogen due to addition of sodium acetate. In water, sodium acetate splits into sodium and acetate ions.

So we can conclude that when sodium acetate is dissolved in water, it is hydrolyzed into ions.

The number of grams of iron present in 14.79 cm length of the same iron rod is 640.51 g.

Ounces is a unit of mass which is used to define a very little amount of anything.

In the question, given that:

In one inch of iron rod whose weighs is 3.88 ounces = 2.54 cm long

In 1 g = 0.035273 ounces present

So we can calcuylate the number of grams in which 3.88 ounces present as:
x = (3.88 ounces) / (0.035273 ounces/g)

x = 110g

So, in 110g = 3.88 ounces present

And in 2.54 cm = 110g of iron present

In 14.79 cm, present grams of iron can be calculated as:

y = (14.79cm x 110g) / 2.54cm

y = 640.51 g

Hence option (c) is correct i.e. 640.51 g.

The weight of the iron rod with 14.79 cm length with same density is given by: Option C; 640.51 g

Suppose that a finite amount of substance is there having its properties as:

Then, they are related as:

[tex]d = \dfrac{m}{v}[/tex]

We know that:

Now, from the facts given in the problem, we have:

The weight of first iron rod which is one inches long = 3.88 ounces

The new rod is 14.79 cm long. And 1 cm = 0.3937 inches approx, thus the new rod is: [tex]14.79 \times 0.3937 \approx 5.8228 \: \rm inches[/tex]

As for 1 inch long rod, there is  weight of 3.88 ounces, thus:

for 5.8228 inch rod, the weight of the rod would be [tex]5.8228 \times 3.88 \approx 22.5924 \: \rm ounces[/tex]

And since 1 ounce = 28.3495 g approx

Thus, weight of the new rod in grams would be [tex]22.5924\times 28.3495 \approx 640.485 \approx 640.51\: \rm g[/tex]

Thus, the weight of the iron rod with 14.79 cm length with same density is given by: Option C; 640.51 g

The name of salt consist of two parts. The first part is the name of metal and second is the name of nonmetal.

So we name the cation first and then anion.

IN given formula cation is potassium while anion is iodine.

The -ine of anion is converted into -ide. Thus the name will be potassium iodide.

Fe₂O₃

First of all we will write the name of cation and then anion.

               Iron    oxygen

Then the we will add -ide at the end of name of anion such as, oxide, chloride, fluoride etc.

               Iron oxide

Now we will calculate the charge on oxygen and iron. We know that the charge on oxide is -2 and thus the total charge on oxygen is 3(-2) = -6. Thus iron must have +3 oxidation state to cancel the charge and make compound neutral. It means 2(+3) = +6

The oxidation state of transition metal will be written in parentheses.

               Iron(III) oxide

(NH₄)₃PO₄

To write the name we must know which is cation and which is anion.

In given formula NH₄⁺ is cation and it carry +1 charge while PO₄³⁻ is anion and it carry -3 charge.

When we write the name we write first the name of cation and then anion.

Here the cation name is ammonium while anion name is phosphate thus the name of compound is ammonium phosphate.

In order to make the compound neutral the opposite charges must be equal to cancel each other.

That's why three ammonium ions are attached with one phosphate ion to make the compound neutral.

Answer:

C ≈ 1.44 × 10⁻³ mol/m³

Explanation:

The given information are;

The liquid volume the pond can hold = 104 m³

The volume of inflow into the pond = 5 m³/h

The volume of outflow into the pond = 5 m³/h

The concentration of the chemical in the inflow water = 0.01 mol/m³

The concentration of the chemical discharged directly into the water = 0.1 mol/h

The concentration, [tex]c_{(inflow)}[/tex], of chemical that enters the water through inflow per hour is given as follows;

[tex]c_{(inflow)}[/tex] = 0.01 mol/m³ × 5 m³/h = 0.05 mol/h

The concentration, [tex]c_{(discharge)}[/tex], of chemical that enters the water through direct discharge per hour is given as follows;

[tex]c_{(discharge)}[/tex] = 0.1 mol/h

The total concentration that enters the pond per hour is given as follows;

[tex]c_{(inflow)}[/tex] + [tex]c_{(discharge)}[/tex] = 0.1 mol/h + 0.05 mol/h = 0.15 mol/h

Whereby the water in the pond properly mixes with the pond, we have;

The concentration of chemicals (C) in the outflow water = 0.15 mol/(104 m³) ≈ 0.00144 mol/m³

C ≈ 1.44 × 10⁻³ mol/m³.

It is defined as a substance which cannot be broken down further into any other substance. Each element is made up of its own type of atom. Due to this reason all elements are different from one another.

Elements can be classified as metals and non-metals. Metals are shiny and conduct electricity and are all solids at room temperature except mercury. Non-metals do not conduct electricity and are mostly gases at room temperature except carbon and sulfur.
