Why packaging lemons in cans might not be a good idea?

Answer:

A. The ratio of the element in glucose is different than in ethanol

Explanation:

The compounds given are;

      Glucose      C₆H₁₂O₆

     Ethanol         C₂H₆O

The two compounds given are different from one another. But they have the same elemental composition.

   Ethanol is made up of Carbon, hydrogen and Oxygen and so also, Glucose

Now,

  The number of atoms in both compounds are different;

                                   Number of atoms

                        C                             H                     O

Glucose           6                             12                      6

Ethanol            2                              6                       1

To Find :

The mass, in grams, of [tex]1.505 \times 10^{23}[/tex] molecules of carbon disulfide (CS₂).

Solution :

Molecular mass of CS₂ = 76 gm/mol .

It means that mass of [tex]6.022 \times 10^{23}[/tex] molecules of CS₂ is 76 gm/mol.

Let, mass of [tex]1.505 \times 10^{23}[/tex] molecules of carbon disulfide (CS₂) is x.

So,

[tex]x= 76\times \dfrac{1.505 \times 10^{23}}{6.022\times 10^{23}}\\\\x = 76 \times \dfrac{1.505}{6.022}\\\\x = 19 \ gm[/tex]

Therefore, the mass in gram is 19 gm.

Answer:

Sublimation is the transition in physical state from solid (ice) to vapor with no intermediate liquid stage. In other words, the ice becomes water vapor without melting. Ideal weather conditions would be low humidity (to allow vaporization), high altitude (lower air pressure facilitates the transition), and strong sunlight (to provide the energy for the transition). High snow-packed mountain ranges offer all of these conditions. Since the temperature is too cold for evaporation, sublimation is needed to provide enough water vapor to feed the water cycle and promote precipitation elsewhere on the planet. Without it, the water would stay frozen in the snow and ice and reduce the amount of liquid water that would replenish the planet.

Explanation:

A buffer is made from an acid - base conjugate pair as shown by option A

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.

A) 3amu

Explanation:

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.

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.

Explanation:

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.

Answer:

noble gases

The noble gases rarely form compounds. They have the most stable configuration (full octet, no charge), so they have no reason to react and change their configuration. All other elements attempt to gain, lose, or share electrons to achieve a noble gas configuration

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]

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.

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.

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
