Calculate the final temperature (once the ice has melted) of a mixture made up initially of 70.0 mL liquid water at 28 oC and 5.0 g ice at 0.0 oC.

Answers

Answer:

21.52° C

Explanation:

From the given information:

mass of the liquid water = 70.0 mL

Initial temperature = 20°C

mass of the ice = 5.0 g

temperature of ice = 0.0°C

Using the calorimetric function:

heat lost by water = heat gained by ice.

mass of water × specific heat of water (s) × ΔT = mass of ice × specific heat of ice (s) × ΔT + n (ΔH_fusion}

⇒ 70 × 4.184 × (28 -x) = 5 × 2.108(x - 0) + [tex](\dfrac{5}{18})[/tex] × 6.01 × 10³

By solving the above equation,

x = 21.52° C

The final temperature of the mixture of water and ice is 21.5 ⁰C.

The given parameters;

initial volume of the liquid = 70 mL initial temperature of the water, = 28⁰Cmass of the ice, = 5.0 gtemperature of the ice, = 0⁰ Cspecific heat capacity of ice = 2.09 J/g ⁰Cheat of fusion of ice = 333.55 J/gspecific heat capacity of water = 4.184 J/g⁰ Cdensity of water = 1 g/ml

Let the final temperature of the mixture = t

mass of the liquid water = 1 g/ml  x 70 ml = 70 g

Apply the principle of conservation of energy to determine the final temperature of the mixture;

heat lost by water = heat gained by ice

[tex]70 \times 4.184(28 - t) = 5\times 2.09(t - 0) \ + \ 5 \times 333.55\\\\8200.64 - 292.88t = 10.45 t + 1667.75\\\\303.33t = 6532.89\\\\t = \frac{6532.89}{303.33}\\\\t = 21.5 \ ^0C[/tex]

Thus, the final temperature of the mixture of water and ice is 21.5 ⁰C.

Answers

Answer:

23.55°C

Explanation:

Based on the equation:

Ca²⁺(aq) + 2F⁻(aq) → CaF₂(s) ∆H°=-11.5 kJ

When 1 mole of Ca²⁺ and 2 of F⁻ reacts, 11.5kJ are released.

Thus, we need to find moles of reaction to find the heat released and using:

C = SₓmₓΔT

We can find the final temperature as follows:

Moles of reaction:

0.0500L * (0.400mol / L) = 0.0200moles Ca²⁺ = Moles of reaction

Heat produced is:

0.0200 moles * (11.5kJ / mol) = 0.23kJ

Using:

C = SₓmₓΔT

Where C is heat = 230J

S is specific heat = 4.18J/g

m is mass of solution = 100.00g

And ΔT is change in temperature

230J = 4.18J/gₓ100.00gₓΔT

ΔT = 0.55°C

As initial temperature is 23.0°C

Final temperature = 23.0°C + 0.55°C =

23.55°C

The final temperature of the solution is 23.55°C.

We were given the equation

Ca²⁺(aq) + 2F⁻(aq) → CaF₂(s) ∆H°=-11.5 kJ

This means that 1 mole of Ca²⁺ and 2 of F⁻ reacts to form CaF₂ and  1.5kJ is released.

The formula we need to use is C = SₓmₓΔT

where c is heat, s is specific heat, m is number of mole and ΔT is temperature change.

We need to find the moles of reaction first

Moles of reaction = 0.0500L × (0.400mol / L) = 0.0200moles Ca²⁺

Heat produced = 0.0200 moles ×11.5kJ / mol = 0.23kJ

We can then substitute into the formula

C = SₓmₓΔT

C = 230J

S = 4.18J/g

m = 100.00g

ΔT= ?

230J = 4.18J/gₓ100.00gₓΔT

         = 0.55°C

Since the  initial temperature is 23.0°C

The Final temperature will be 23.0°C + 0.55°C

                                               =23.55°C

The rotation speed and revolution speed should be switched. The revolution speed and solar system speed should be switched. The rotation speed and Milky Way speed should be switched.

Answers

Answer:The Solar System speed and Milky Way speed should be switched

Explanation:

The Milky Way speed and solar system speed should be switched with each other. Therefore, option (A) is correct.

What is the speed of the earth's revolution and rotation?

The rotation of the earth can be described as the spinning of the Earth around its own axis. The axis has an angle of 23(1/2)° and it is perpendicular to the plane of the orbit of the earth. The northern and southern hemispheres lean in a direction away from the Sun because Earth is tilted on its axis. The rotation speed of the earth is 0.3 miles/sec.

The Revolution of the earth is the movement of the Earth around the Sun in a fixed path. The revolution speed of the earth is 30 Km/s or 18.5 miles/sec. The milky way speed of the earth is 370 miles/sec and the solar system speed of the earth is 130 miles/sec.

But according to Luca's chart, the milky way speed is 150 miles/sec and the solar system speed is 370 miles/sec.

Therefore, the solar system speed and Milky Way speed need to be switched.

To distinguish one atom from another or to classify the various atoms, a number which indicates the number of protons in the nucleus of a given atom, is assigned to the atoms of each identified element. This number is known as the atomic number of the element. The atomic numbers for some of the elements which are associated with the study of semiconductors are given in the following table.

Answer:

[tex]\boxed {\boxed {\sf Protons \ and \ neutrons}}[/tex]

Explanation:

The atom is made up of two main parts: the nucleus and the electron cloud.

The nucleus is the center and has two subatomic particles: the protons (positive charge) and the neutrons (no/neutral charge). The nucleus as a whole has a positive charge, since the neutrons don't provide a charge.

The electron cloud surrounds the nucleus and houses the negatively charged electrons in a "cloud" of energy levels.

So, the nucleus of the atom is made up of protons and neutrons.

Answers

Answer:

Explanation:

Here's is the reaction:

2HgO(s) ⇒ 2 Hg(s)+O₂(g)

In this reaction 2mol HgO =  1mol O₂

The molecular weight of HgO = 216.59g

so, 3.0g HgO = 3.0g x 1.00molHgO/216.59gHgO

= 0.0138511 molHgO

The amount of Oxygen follows:

0.0138511 molHgOx1/2= 0.00692555 mol O₂

Now, volume of 1 any gas = 22400mL

so, 0.00692555 mol O₂ x22400mLO₂/1mol O₂

Answers

Answer:

Increasing the temperature of 1 mol of C8H18(l) requires more energy

Explanation:

To answer this question, we need to define molar heat capacity that is the amount of heat required to increase in 1K the temperature of 1 mole of substance.

That means the substance with higher molar heat requires more energy to increase its temperature

Molar heat of octane, C8H18 is 255.68J/Kmol

Molar heat of water is 75.38J/Kmol

That means increasing the temperature of 1 mol of C8H18(l) requires more energy
