Below is the balanced equation for the production of methane. Use it to explain how the law of conservation of matter is upheld in the decomposition of organic trash. 4C2H5O2N + 2H2O → 3CH4 + 5CO2 + 4NH3 Glycine + Water yields Methane + Carbon dioxide + Ammonia
Answer:
See explanation
Explanation:
A balanced equation demonstrates the conservation of mass because the same number of of atoms of each element is found on both sides of the reaction equation.
This goes a long way to establish that mass or matter can neither be created nor destroyed but may be transformed from one form to another.
Looking at this balanced reaction equation;
4C2H5O2N + 2H2O → 3CH4 + 5CO2 + 4NH3
There are eight carbon atoms on both sides of the reaction equation
There are 24 hydrogen atoms on both sides of the reaction equation
There are 10 oxygen atoms on both sides of the reaction equation
There are four nitrogen atoms on both sides of the reaction equation
Hence, the law of conservation of matter is upheld in the decomposition of organic trash.
The balanced equation for the production of methane:
[tex]4C_2H_5O_2N + 2H_2O ----> 3CH_4 + 5CO_2 + 4NH_3[/tex]
Balanced chemical equation:A balanced chemical equation occurs when the number of the atoms involved in the reactants side is equal to the number of atoms in the products side. According to the law of conservation of mass, when a chemical reaction occurs, the mass of the products should be equal to the mass of the reactants.
From given balanced equation for the production of methane:
[tex]4C_2H_5O_2N + 2H_2O ----> 3CH_4 + 5CO_2 + 4NH_3[/tex]
There are 8 carbon atoms, 24 hydrogen atoms, 10 oxygen atoms and 4 nitrogen atoms on both sides of the reaction equation, i.e. equal number of atoms on both reactants and products side.
Hence, the law of conservation of matter is upheld in the decomposition of organic trash.

The potassium is an alkali metal which explode in water to produce base and hydrogen gas. The balancing came from the fact that each side needed the same number of hydrogens so I made the products have 4 (the lowest even number) then put the appropriate coefficients in the reactants to make that work. Since there are two molecules of potassium hydroxide there also needed to be 2 atoms of potassium in the reactants.

Explanation:
Will sodium displace iron from iron oxide?
Answer:
Explanation: A more reactive metal will displace a less reactive metal from a compound. The thermite reaction is a good example of this. It is used to produce white hot molten (liquid) iron in remote locations for welding. A lot of heat is needed to start the reaction, but then it releases an incredible amount of heat, enough to melt the iron.
aluminium + iron(III) oxide → iron + aluminium oxide
2Al + Fe2O3 → 2Fe + Al2O3
Because aluminium is more reactive than iron, it displaces iron from iron(III) oxide. The aluminium removes oxygen from the iron(III) oxide:
Answer:
Displacement reactions involve a metal and a compound of a different metal. In a displacement reaction:
Explanation:
a more reactive metal will displace a less reactive metal from its compounds
Displacement reactions are easily seen when a salt of the less reactive metal is in the solution. During the reaction:
the more reactive metal gradually disappears as it forms a solution
the less reactive metal coats the surface of the more reactive metal
For example, magnesium is more reactive than copper. When a piece of magnesium is dipped into blue copper sulfate solution:
the blue colour fades as colourless magnesium sulfate solution forms
brown copper coats the surface of the magnesium
I hope this is correct or answers your question :)
Consider a 0.10 M solution of a weak polyprotic acid (H2A) with the possible values of Ka1 and Ka2 given below. Calculate the contributions to [H3O+] from each ionization step. Ka1=1.0×10−4;Ka2=5.0×10−5
Answer:
The first dissociation occurred at 0.00311 M and the second at 0.0000484 M.
Explanation:
From the given information:
The ICE table can be computed as follows:
H2A → HA⁻ + H⁺
Initial 0.10 0 0
Change -x x x
Equilibrium 0.10 - x x x
[tex]Ka_1 = \dfrac{[HA^-][H^+]}{[H_2A]}[/tex]
[tex]1.0\times 10^{-4}= \dfrac{[x][x]}{[0.10-x]}[/tex]
[tex]1.0\times 10^{-4}= \dfrac{(x)^2}{(0.10-x)}[/tex]
By solving for x;
x² = (1.0 × 10⁻⁴ × 0.1)
x = [tex]\sqrt{1\times 10^{-5}}[/tex]
x = [H⁺] =[HA⁻] = 0.00311 M
The acid then further its dissociation again, So;
The ICE table can be computed as follows:
HA⁻ → A⁻ + H⁺
Initial 0.00311 0 0.00311
Change -x x x
Equilibrium 0.00311 - x x 0.00311 + x
[tex]Ka_2 = \dfrac{[A^-][H^+]}{[HA]}[/tex]
[tex]5.0 \times 10^{-5} = \dfrac{(0.00311+x)x}{(0.00311-x)}[/tex]
By solving for x;
x = [H⁺] = 0.0000484 M
Therefore, the first dissociation occurred at 0.00311 M and the second at 0.0000484 M.
Calculate the atoms of hydrogen in 52.0 g of H2O.
Answer:
34.81 ×10²³ atoms
Explanation:
Given data:
Mass of water = 52.0 g
Number of atoms of hydrogen = ?
Solution:
Number of moles of water:
Number of moles = mass/molar mass
Number of moles = 52.0 g/ 18 g/mol
Number of moles = 2.89 mol
1 mole of water contain 2 mole of hydrogen.
2.89 mole of water contain 2.89× 2= 5.78 moles of hydrogen.
Number of atoms of hydrogen:
1 mole = 6.022×10²³ atoms
5.78 mol × 6.022×10²³ atoms / 1mol
34.81 ×10²³ atoms
Señalar la opción correcta El primer alcalino y el primer gas noble tienen la misma cantidad de niveles ocupados El primer alcalinotérreo tiene 2 e en su CEE El cuarto halógeno tiene 5 electrones de valencia
Answer:
El primer gas alcalino y el primer gas noble tienen el mismo número de niveles ocupados. Cierto.
La primera tierra alcalina tiene 2 e en su CEE. Cierto.
El cuarto halógeno tiene 5 electrones de valencia. Falso.
Explicación:
El primer alcalino y el primer gas noble tienen el mismo número de niveles ocupados porque el primer alcalino tiene 1 electrón y solo tiene una capa, mientras que el gas noble tiene 2 electrones y también tiene una capa. El primer alcalinotérreo tiene 2 e en su CEE debido a la presencia en el segundo grupo en la tabla periódica. El cuarto halógeno no tiene 5 electrones de valencia en su capa más externa, tiene 7 electrones en su capa más externa debido a la presencia en el grupo de siete de la tabla periódica.

Form a bond: Each electron has a charge of 1–, and each proton has a charge of 1+. You can calculate the charge of an atom by subtracting the number of electrons from the number of protons. Move an electron from the sodium to the chlorine atom.
1. Sodium has a charge of 1+ and chlorine has a charge of 1-
2. Chlorine has a charge of 1+ and sodium has a charge of 1-
3. Both atoms have a charge of 1+
4. Both atoms have a charge of 1-
Answer:
1. Sodium has a charge of 1+ and chlorine has a charge of 1-
Explanation:
Sodium has 11 protons and 11 electrons. If you remove one electrons we now have only 10 electrons.
Hence; number of protons - number of electrons = 11 - 10 = +1
Sodium has a charge of +1
Chlorine has 17 electrons and 17 protons. if it gains 1 electron then it now has 18 electrons.
Hence; number of protons - number of electrons = 17 - 18 = -1
Chlorine has a charge of -1

What is a buffer made from?
A buffer is made from an acid - base conjugate pair as shown by option A
What is a buffer?Buffers are often composed of weak acids and their conjugate bases (or weak bases and their conjugate acids). The weak acid can contribute a proton to balance any new base, whereas the conjugate base can absorb a proton to do so.
This balance between the acid and its conjugate base allows the buffer to survive pH changes. Buffers are essential in biological systems because many biochemical processes are particularly sensitive to pH changes.

Carbonate is a polyatomic ion whose oxidation number is -2. How many carbonate ions would be required to bond with aluminum in a neutral ionic compound?
Answer: Three carbonate ions are required to bond with aluminum in a neutral ionic compound.
Explanation:
An ionic compound is defined as the compound that is formed by the complete transfer of electrons takes place from one atom (forming cation) to another atom (forming anion).
A neutral ionic compound does not carry any charge on it.
As we know, aluminum is a trivalent atom having valency 3 and forms [tex]Al^{3+}[/tex] ion and carbonate is a divalent polyatomic ion having formula [tex]CO_3^{2-}[/tex].
They both combine to form a neutral ionic compound named aluminum carbonate.
By criss cross method, the chemical formula of aluminum carbonate is [tex]Al_2(CO_3)_3[/tex]
Hence, three carbonate ions are required to bond with aluminum in a neutral ionic compound.

Heterotrophic living organisms include all animals and fungi, some protists and bacteria, many types of parasitic plants.
Carnivores (organisms that eat meat) and omnivores (organisms that eat plants and meat) occupy the third level.
