Answer:

Rusting is an oxidation reaction. The iron reacts with water and oxygen to form hydrated iron (III) oxide, which we see as rust. Here is the word equation for the reaction: iron + water + oxygen → hydrated iron (III) oxide

In this reaction, zinc atoms each will lose two electrons (oxidation) and become Zn 2+ ions. The two electrons that are released by zinc will be gained by the Cu 2+ ions (reduction). The Cu2+ ions become Cu atoms. Total equation: Zn (s) + CuSO 4 (aq) --> Cu (s) + ZnSO 4 (aq)

Explanation:

La manera en la que se podría organizar un grupo institucional o comunal para contribuir en el cuidado de los recursos hídricos de la comunidad, es a través de la formación de Comités interinstitucionales que mitiguen el impacto del cambio climático.

> Primero que nada, es que exista la voluntad política entre cada una de las partes que conformarán el grupo institucional.

> Después, elegir a un Comité que presida las reuniones. Habría un representante gubernamental en ese Comité.

> En ese Comité estarán los líderes de cada agrupación representada.

> Establecer una agenda con los temas, las fechas y los objetivos que se desean conseguir.

> Tener la voluntad política de negociar abiertamente y no anteponer agendas personales y menos, intereses políticos.

> El gobierno tendría que reconocer la autorizad representativa de ese grupo para que realmente sus peticiones tuvieran un peso específico en la toma de decisiones.

> El gobierno debe asignar un presupuesto para que la agrupación pueda operar y en realidad fuera un grupo útil.

Podemos concluir que además del esfuerzo comunal y gubernamental, se podría considerar la participación de la iniciativa privada para fortalecer el presupuesto y los programas de acción para mantener limpios los recursos hídricos de la comunidad.

Answer:  FeO2

Explanation:

 1.116       g  Fe

0.480     g O

We want to compare the NUMBER of Fe and O atoms.  We only have their masses, but since the molar mass of Fe is 5 times that of O, let's multiply the grams of O by 5 to have it "catch up" to the iron in ternms of number of atoms.   If the molar masses were the same, the masses would be in direct proportion to the formula.  Since they aren't, multiply by the molar mass ratio:

(1.116 grams Fe) x 1 = 1.116 g Fe

(0.480 g O) x 5 = 2.40 g O  [Changes the O mass into a number that correlates with the number of atoms relative to iron],

If the molar masses were the same, this would be the ratio of O to Fe atoms in the compound.  Normalize to the Fe number by dividing both by 1.116:

Fe = 1

O = 2.15

Not perfect, but an empiricle formula of FeO2 makes sense.  I don't see enough information here to prove that this is also the molecular formula, but FeO2 is a valid compound.  Fe(IV)O2,

1. The empirical formula of the compound is Fe₂O₃

2. The molecular formula of the compound is Fe₂O₃

1. Determination of the empirical formula of the compound.

Fe = 1.116 g

O = 0.480 g

Divide by their molar mass

Fe = 1.116 / 56 = 0.02

O = 0.480 / 16 = 0.03

Divide by the smallest

Fe = 0.02 / 0.02 = 1

O = 0.03 / 0.02 = 1.5

Multiply by 2 to express in whole number

Fe = 1 × 2 = 2

O = 1.5 × 2 = 3

Therefore, the empirical formula of the compound is Fe₂O₃

2. Determination of the molecular formula of the compound.

Empirical formula = Fe₂O₃

Molar mass = 5 × molar mass of O₂ = 5 × 32 = 160 g/mol

Molecular formula = empirical × n = molar mass

[Fe₂O₃]n = 160

[(2×56) + (3×16]n = 160

[112 + 48]n = 160

160n = 160

Divide both side by 160

n = 160 / 160

n = 1

Molecular formula = [Fe₂O₃]n

Molecular formula = [Fe₂O₃] × 1

Glasswares are glass containers and objects. An Erlenmeyer flask is a piece of glassware that is cone-shaped except for a cylinder-shaped opening. Thus, option B is correct.

Erlenmeyer flask has been commonly called titration or conical flask used in the laboratory to titrate the solution in an experiment. It was named after Emil Erlenmeyer, a German chemist. They are used to heat, cool, mix, titrate, and incubate processes.

They have a distinct shape with a round flat bottom and a narrow neck region that allows swirling and mixing of the solution without any spills. Its narrow opening accommodates the filter funnel that can be used for filtration.

Therefore, option B. Erlenmeyer flask (conical flask) is cone-shaped glassware.

Answer:

The mass of CO22 in total is 264 g.

The atomic mass for C is 12 g / mole.

The molar mass for CO22 is (12 + (2 × 16)) = 44 g / mole.

m C = (12 / 44) × 264 = 72 g

So, there are 72 g of C in 264 g of CO2

Answer:

0.034 = 34×10^-3

Explanation:

This is because the special point is notated until it goes in front of the first counting number

Scientific notation is a way of expressing numbers that are very large or very small in a compact and standardized format. 0.034 in scientifc notation is written as 3.4 × 10⁻³

In scientific notation, a number is expressed as the product of a coefficient and a power of 10. The coefficient is a decimal number greater than or equal to 1 but less than 10, and the power of 10 represents the magnitude of the number. The power of 10 indicates the number of places the decimal point must be moved to obtain the original number.

For example:

The number 4,500,000 can be written in scientific notation as 4.5 x 10⁶, where the coefficient is 4.5 and the power of 10 is 6.

The number 0.000043 can be written in scientific notation as 4.3 x 10⁻⁵, where the coefficient is 4.3 and the power of 10 is -5.

Scientific notation allows for easy representation of very large or small numbers and simplifies calculations involving these numbers. It is particularly useful in scientific fields where values such as distances, masses, and concentrations can vary over a wide range.

Answer:

[tex]\boxed {\boxed {\sf 0.541 \ mol \ Na_2CO_3}}[/tex]

Explanation:

We are asked to find how many moles of sodium carbonate are in 57.3 grams of the substance.

Carbonate is CO₃ and has an oxidation number of -2. Sodium is Na and has an oxidation number of +1. There must be 2 moles of sodium so the charge of the sodium balances the charge of the carbonate. The formula is Na₂CO₃.

We will convert grams to moles using the molar mass or the mass of 1 mole of a substance. They are found on the Periodic Table as the atomic masses, but the units are grams per mole instead of atomic mass units. Look up the molar masses of the individual elements.

Remember the formula contains subscripts. There are multiple moles of some elements in 1 mole of the compound. We multiply the element's molar mass by the subscript after it, then add everything together.

We will convert using dimensional analysis. Set up a ratio using the molar mass.

[tex]\frac {105.9875386 \ g \ Na_2CO_3}{1 \ mol \ Na_2CO_3}[/tex]

We are converting 57.3 grams to moles, so we multiply by this value.

[tex]57.3 \ g \ Na_2CO_3} *\frac {105.9875386 \ g \ Na_2CO_3}{1 \ mol \ Na_2CO_3}[/tex]

Flip the ratio so the units of grams of sodium carbonate cancel.

[tex]57.3 \ g \ Na_2CO_3} *\frac {1 \ mol \ Na_2CO_3}{105.9875386 \ g \ Na_2CO_3}[/tex]

[tex]57.3 } *\frac {1 \ mol \ Na_2CO_3}{105.9875386 }[/tex]

[tex]\frac {57.3 }{105.9875386 } \ mol \ Na_2CO_3[/tex]

[tex]0.5406295944 \ mol \ Na_2CO_3[/tex]

The original measurement of moles has 3 significant figures, so our answer must have the same. For the number we found that is the thousandth place. The 6 in the ten-thousandth place to the right tells us to round the 0 up to a 1.

[tex]0.541 \ mol \ Na_2CO_3[/tex]

There are approximately 0.541 moles of sodium carbonate in 57.3 grams.

At standard room temperature, [tex][{\rm OH^{-}] \approx 2.5 \times 10^{-7}\; \rm M[/tex] when [tex][{\rm H^{+}] = 4.0 \times 10^{-8}\; \rm M[/tex].

Explanation:

The following equilibrium goes on in water:

[tex]{\rm H_{2}O}\, (l) \rightleftharpoons {\rm H^{+}}\, (aq) + {\rm OH^{-}}\, (aq)[/tex].

The forward reaction is known as the self-ionization of water. The ionization constant of water, [tex]K_{\rm w}[/tex], gives the equilibrium position of this reaction:

[tex]K_{\rm w} = [{\rm H^{+}] \cdot [{\rm OH^{-}}][/tex].

At standard room temperature ([tex]25\; {\rm ^{\circ}C}[/tex]), [tex]K_{\rm w} \approx 10^{-14}[/tex]. Also, [tex][{\rm H^{+}}] = 4.0 \times 10^{-8}\; \rm mol \cdot L^{-1}[/tex]. Substitute both values into the equation and solve for [tex][{\rm OH^{-}}][/tex].

[tex]\begin{aligned} {[}{\rm OH^{-}}{]} &= \frac{K_{\rm w}}{[{\rm H^{+}}]} \\ &\approx \frac{10^{-14}}{4.0 \times 10^{-8}} = 2.5 \times 10^{-7}\end{aligned}[/tex].

In other words, in an aqueous solution at standard room temperature, [tex][{\rm OH^{-}] \approx 2.5 \times 10^{-7}\; \rm M[/tex] when [tex][{\rm H^{+}] = 4.0 \times 10^{-8}\; \rm M[/tex].
