As the soil absorbs manure, nutrients are released. This enriches the soil, which in turn helps the plants. The most important benefit of using manure in the garden is its ability to condition the soil For instance, mixing manure with sandy soils helps to retain moisture levels.

Chemists need the mole concept to bridge the gap between the microscopic world of atoms to the macroscopic world of humans. As you know, the molecular level consists of particles that are invisible to us.

Answer:

it allows us to count atoms and molecules by weighing macroscopic amounts of material.

Answer:

In molecules, there is a pattern to the number of covalent bonds that different atoms can form. Each block with a number indicates the number of covalent bonds formed by that atom in neutral compound

Answer:

Atom

Explanation:

An atom can absorb or emit one photon when an electron makes a transition from one stationary state, or energy level, to another. Conservation of energy determines the energy of the photon and thus the frequency of the emitted or absorbed light.

Answer:

I don't know

Explanation:

pls I need a little bit answer

Answer:

Here

Explanation:

When the atom absorbs energy, it can move to a higher energy state, or excited state. Under what circumstances can an atom emit a photon? A photon is emitted when an atom moves from an excited state to its ground state or to a lower-energy excited state.

Rigor mortis is the stiffening of the body after death. After death, the body begins to get cold. From about two to six hours after death, the muscles start to stiffen, probably because the actin and myosin filaments of the muscle slide into each other. The rigor mortis starts at the eyelids, jaw and neck and then slowly spreads to all parts of the body within six hours.

Contrary to popular belief, rigor mortis will occur more quickly in high ambient temperatures than in cold conditions. This is because the underlying chemical reaction occurs faster at higher temperatures.

Have a good day and drink some water plz

The food molecules during cellular respiration they undergo chemical reactions with oxygen, releasing stored energy.

Chemical reaction is defined as a procedure in which one or more substances, known as reactants, are converted into one or more different substances, known as products.

It can also be defined as a method of chemically transforming one set of chemical substances into another.

There are basically six types of chemical reaction.

Cellular respiration is defined as the process of oxidizing biological fuels in the presence of an inorganic electron acceptor such as oxygen to produce large amounts of energy, which drives the bulk production of ATP.

It can also be defined as the process by which sugar from food is converted into energy within cells.

Thus, the  food molecules during cellular respiration they undergo chemical reactions with oxygen, releasing stored energy.

Bromo-ethene is a product and it is a electrophilic addition reaction.

A chemical equation is a method of representing a symbols and formulas of substance involved in this equation.

For example:  zinc metal reacts with dilute sulfuric acid to form zinc sulfate and hydrogen gas.

Types of chemical reactions:

Electrophilic addition reaction

In this reaction containing a double or triple bond and this one hour breakdown into 2 π and 2 Sigma bonds.

In this reaction HBr undergoes heterolytic bond fusion the protons bonds with the carbon atom of the Carbon triple bond this result in the formation of carbo cation immediate the bromide iron forms a bond with the carbon cation producing Bromo-Ethene.

CH ≡ CBr + 2HBr  →  Br-CH=CH₂ (Bromo-ethene)

In these reaction Bromo-ethyne react with hydrogen bromide it form Bromo-ethene.

Bromo-ethene is a product and it is a electrophilic addition reaction.

Answer:

The required mass to prepare 2.5 L of 1.0 M NaOH solution is 100 g

Explanation:

We do this by preparing the equation:

Mass = concentration (mol/L) x volume (L) x Molar mass

Mass = 1.0 M x 2.5 L x 40 g/mol

Mass = 100 g

Answer:

[tex]100\; \rm g[/tex] of [tex]{\rm NaOH}\; (s)[/tex] would be required.

Explanation:

The quantity of solute in a solution of concentration [tex]c[/tex] and volume [tex]V[/tex] would be [tex]n = c \cdot V[/tex].

It is given that volume [tex]V = 2.5\; \rm L[/tex] for the solution in this question. It is also given that the concentration of the [tex]\rm NaOH[/tex] solute in this solution is [tex]c = 1.0\; \rm M[/tex], which is the equivalent to [tex]c = 1.0\; \rm mol \cdot L^{-1}[/tex].  

Apply the equation [tex]n = c \cdot V[/tex] to find the quantity of [tex]\rm NaOH[/tex] in this solution:

[tex]\begin{aligned}n &= c \cdot V \\ &= 1.0\; \rm mol \cdot L^{-1} \times 2.5\; \rm L \\ &= 2.5\; \rm mol\end{aligned}[/tex].

Multiply the quantity [tex]n[/tex] of [tex]\rm NaOH[/tex] in this solution with the formula mass [tex]M[/tex] of [tex]{\rm NaOH}\![/tex] to find the corresponding mass:

[tex]\begin{aligned}m &= n \cdot M \\ &= 2.5\; \rm mol \times 40\; \rm g \cdot mol^{-1} \\ &= 100\; \rm g\end{aligned}[/tex].

Thus, this solution would contain [tex]100\; \rm g[/tex] of [tex]{\rm NaOH}[/tex].

It would thus take [tex]100\; \rm g[/tex] of [tex]{\rm NaOH}[/tex] to prepare this solution.
