Answer: 23 g

Explanation:

Amountafter = Amountbefore * (1/2)^(t/thalf)

Amountafter = (750 grams) * (1/2)^(62.0 hours/12.4 hours)

Amountafter = 23.4375 grams

750 has 2 significant digits

12.4 and 62.0 have 3 significant digits

So we take the lower of 2 significant digits:

23 grams

The half-life of 42K is 12.4 hours. 23.4375 grams of a 750 grams sample left after 62.0 hours.

Half life is the amount of time required to reduce to one-half of its initial value. The symbol of half life is \(t_{1/2}\).

It is expressed as:

\(N(t) = N_{0} (\frac{1}{2})^{\frac{t}{t_{1/2}}\)

where,

N(t) = quantity remaining

N₀ = initial quantity

t = elapsed time

\(t_{1/2}\) = half-life of the substance

Here,

N₀ = 750.0 g

t = 62 hr

\(t_{1/2}\) = 12.4

Now put the values in above equation we get

\(N(t) = N_{0} (\frac{1}{2})^{\frac{t}{t_{1/2}}\)

\(N(t) = 750 \times (\frac{1}{2} )^{\frac{62}{12.4}}\)

\(N(t) = 750 \times (\frac{1}{2})^5\)

\(N(t) = 750 \times \frac{1}{32}\)

N(t) = 23.4375 grams

Thus, from the above conclusion we can say that the 23.4375 grams of a 750 grams sample left after 62.0 hours.

Approximately \(1.10\; {\rm V}\) under standard conditions.

Explanation:

Equation for the overall reaction:

\({\rm CuCl_{2}}\, (aq) + {\rm Zn}\, (s) \to {\rm ZnCl_{2}} \, (aq) + {\rm Cu}\, (s)\).

Write down the ionic equation for this reaction:

\(\begin{aligned}& {\rm Cu^{2+}}\, (aq) + 2\; {\rm Cl^{-}}\, (aq) + {\rm Zn}\, (s)\\ & \to {\rm Zn^{2+}} \, (aq) + 2\; {\rm Cl^{-}}\, (aq) + {\rm Cu}\, (s)\end{aligned}\).

The net ionic equation for this reaction would be:

\({\rm Cu^{2+}}\, (aq) + {\rm Zn}\, (s) \to {\rm Zn^{2+}}\, (aq) + {\rm Cu}\, (s)\).

In this reaction:

Look up the standard potentials for each half-reaction on a table of standard reduction potentials.

Notice that \({\rm Zn}\, (s) \to {\rm Zn^{2+}}\, (aq) + 2\, {\rm e^{-}}\) is oxidation and is likely not on the table of standard reduction potentials. However, the reverse reaction, \({\rm Zn^{2+}}\, (aq) + 2\, {\rm e^{-}} \to {\rm Zn}\, (s)\), is reduction and is likely on the table.

The reduction potential of \({\rm Zn}\, (s) \to {\rm Zn^{2+}}\, (aq) + 2\, {\rm e^{-}}\) would be \(-E(\text{anode}) = -(-0.7618\; {\rm V}) = 0.7618\; {\rm V}\), the opposite of the reverse reaction \({\rm Zn^{2+}}\, (aq) + 2\, {\rm e^{-}} \to {\rm Zn}\, (s)\).

The standard potential of the overall reaction would be the sum of the standard potentials of the two half-reactions:

\(\begin{aligned} E^{\circ} &= E^{\circ}(\text{cathode}) + (-E^{\circ}(\text{anode})) \\ &= 0.3419 - (-0.7618\; {\rm V}) \\ &\approx 1.10\; {\rm V}\end{aligned}\).

At this point the volume of the gas is halved. If the pressure on the piston is again doubled, the volume of gas decreases to one-fourth its original volume. FIGURE 9.8 Boyle's Law: At constant temperature, the volume of a gas sample is inversely proportional to the pressure.

The volume of the gas doubles.

Boyles law state that the pressure of a gas is indirectly proportional to the volume at constant temperature. It is given by:

PV = constant

Let us assume that initially the pressure is P and the volume is V, hence:

\(P_1=P,V_1=V\)

The volume decreases to half its original value, hence:

\(P_2=\frac{P}{2}\)

Therefore:

\(P_1V_1=P_2V_2\\\\\\PV=\frac{P}{2}V_2\\\\V_2=2V\)

Therefore the volume of the gas doubles.

Fog remains suspended in the air because they are supported by slight movement in the air

If the air near the ground cools down enough and is humid and light wind (stable), water vapour in the air may condense into minute water droplets. Near ground level, these raindrops make it harder to see. Fog is the term for the phenomenon.

Fog is defined as "air that is near to the surface and contains suspended water droplets, typically generated by diabatic cooling" in Understanding Weather and Climate.

When the air close to the ground cools down sufficiently, the water vapor condenses into liquid water or ice, creating fog. Fog comes in a wide variety of forms. When the air close to the ground is chilly enough, ice fog develops.

The concentration of bicarbonate ion (HCO³⁻) in a 0.010 m H₂CO₃ solution that has the stepwise dissociation constants ka1 is 2.08 x 10⁻⁴ M.

The stepwise dissociation of carbonic acid can be represented as follows:

H₂CO₃ ⇌ H+ + HCO₃- (Ka1)

HCO₃- ⇌ H+ + CO₃²⁻ (Ka2)

We can use the Ka1 expression to find the concentration of HCO3- ion:

Ka1 = [H+][HCO³⁻]/[H₂CO₃]

[H₂CO₃] = 0.010 M (given)

[H⁺] = [HCO³⁻] (since the solution is neutral)

Therefore, Ka1 = [HCO3-]² / 0.010

[HCO³⁻]² = Ka1 x 0.010

[HCO³⁻] = √(Ka1 x 0.010)

Substituting the given value of Ka1 (4.3 x 10⁻⁷), we get:

[HCO³⁻] = √(4.3 x 10⁻⁷ x 0.010) = 2.08 x 10⁻⁴ M

The concentration of bicarbonate ion (HCO3-) is 2.08 x 10⁻⁴ M.

a) To convert 1.65 moles of magnesium chloride to grams, we need to first determine the molar mass of MgCl.

The molar mass of MgCl is the sum of the atomic masses of magnesium and chlorine:

Mg: 24.31 g/mol

Cl: 35.45 g/mol

Molar mass of MgCl = 24.31 g/mol + 35.45 g/mol = 59.76 g/mol

Now, we can use the molar mass to convert 1.65 moles to grams:

1.65 moles x 59.76 g/mol = 98.70 grams

Therefore, 1.65 moles of MgCl is equal to 98.70 grams.

b) To convert grams of Na2CO3 to moles, we need to first determine the molar mass of Na2CO3.

The molar mass of Na2CO3 is the sum of the atomic masses of sodium, carbon, and oxygen, taking into account the two sodium atoms in each molecule:

Na: 22.99 g/mol

C: 12.01 g/mol

O: 16.00 g/mol

Molar mass of Na2CO3 = (2 x 22.99 g/mol) + 12.01 g/mol + (3 x 16.00 g/mol) = 105.99 g/mol

Now, we can use the molar mass to convert grams to moles:

1 grain = 0.06479891 grams

10 grains = 0.6479891 grams

0.6479891 g / 105.99 g/mol = 0.0061 moles

Therefore, 10 grains (0.6479891 grams) of Na2CO3 is equal to 0.0061 moles.

The molar mass (M) of a chemical product is described in chemistry as the ratio of mass to substance (measured in moles) of any sample of said molecule.  The molar mass of a material is a bulk characteristic, not a molecular trait.

The principle of option D. Uniformitarianism states that the physical, chemical, and biological processes at work shaping the Earth today have also operated in the

Option D. Uniformitarianism is the principle stating that the physical, chemical, and biological processes at work shaping the Earth today have also operated in the geologic past. It is based on the idea that the present is the key to the past. In other words, the same natural laws that operate in the universe today have been operating since the beginning of time.

James Hutton was the first to propose this principle in the late 18th century. He suggested that the Earth was shaped by slow-acting geological forces such as erosion, sedimentation, and uplift over long periods of time. He believed that the same processes were still happening today and that they had operated in the past.

This principle is an important concept in geology because it allows scientists to interpret the Earth's history based on the processes that they observe today. By understanding how these processes work and how they have changed over time, scientists can reconstruct the history of the Earth and its environments.

Uniformitarianism has been tested and proven through many observations and experiments. For example, the study of sedimentary rocks has shown that they were formed in the past through the same processes that are observed today, such as deposition of sediment by water, wind, or ice.

Similarly, the study of volcanoes has shown that they are formed by the same processes as today, such as the movement of magma from deep within the Earth.

In conclusion, Uniformitarianism is the principle that allows us to interpret the Earth's history by observing the processes that shape it today. It is a fundamental concept in geology and has been tested and proven through many observations and experiments.
