which has the higher temperature? An iceberg or a steaming cup of water?​

Answers

They’re equally as hot at 50˚C each. However the one with the larger water mass has the most heat energy, as every gram of water at the same temperature contains the same amount of heat energy.

To have zero heat energy a substance has to be at absolute zero. This is 0˚K which equals -273˚C. So there’s already a lot of heat energy in a substance at 0˚C. The amount of heat energy per degree per gram varies depending on the temperature, but in rough terms a gram of ice contains 2.11 Joules for every ˚C above -273˚C. So a gram of ice at 0˚C contains roughly 273*2.11 = 576 Joules of heat energy.

It then takes an additional 334 Joules to melt a gram of 0˚C ice into a gram of 0˚C water. After this a gram of water requires 4.19 Joules for every ˚C above 0˚C, and so heating this water up to 100˚C then requires 100\times 4.19=419 Joules per gram. So the total heat energy in a gram of 100˚C water is 576+334+419=1329 Joules.

Putting this together means that a gram of boiling water contains 1329/576 = 2.3 times as much heat energy as a gram of 0˚C ice, or put another way, 2.3 grams of ice contains the same heat energy as 1 gram of boiling water.

So in answer to the question if you freeze 2.3 cups of water to just 0˚C, the resulting ice will contain roughly the same heat energy as 1 cup of water at 100˚C. Ice out at sea may of course be a few degrees cooler and so you’d need a little more, but you certainly don’t need anything like an iceberg!

Use a scientific calculator to calculate [H+] for the following pH values:

7 (a neutral solution)

5.6 (unpolluted rainwater)

3.7 (first acid rain sample in North America)

How many times higher is the concentration of H+ in the Hubbard Brook sample than in unpolluted rainwater?

Answers

Answer:

pH = 7 ⇒ [H⁺] = 1.0x10⁻⁷ M

pH = 5.6 ⇒ [H⁺] = 2.5x10⁻⁶ M

pH = 3.7 ⇒ [H⁺] = 2.0x10⁻⁴ M

H⁺ concentration in the Hubbard Brook sample is 80 times higher than in unpolluted rainwater.

Explanation:

To answer this problem we need to keep in mind the definition of pH:

pH = -log[H⁺]

Meaning that after isolating [H⁺] we're left with:

[H⁺] = [tex]10^{-pH}[/tex]

Now we proceed to calculate [H⁺] for the given pHs:

pH = 7 ⇒ [H⁺] = [tex]10^{-7}[/tex] = 1.0x10⁻⁷ MpH = 5.6 ⇒ [H⁺] = [tex]10^{-5.6}[/tex] = 2.5x10⁻⁶ MpH = 3.7 ⇒ [H⁺] = [tex]10^{-3.7}[/tex] = 2.0x10⁻⁴ M

Finally we calculate how many times higher is [H⁺] when pH = 3.7 than when pH = 5.6.

2.0x10⁻⁴ / 2.5x10⁻⁶ = 80

Answer:

1. 7 (a neutral solution)

Answer: 10-7= 0.0000001 moles per liter

2. 5.6 (unpolluted rainwater)

Answer: 10-5.6 = 0.0000025 moles per liter

3. 3.7 (first acid rain sample in North America)

Answer: 10-3.7 = 0.00020 moles per liter

The concentration of H+ in the Hubbard Brook sample is 0.00020/0.0000025, which is 80 times higher than the H+ concentration in unpolluted rainwater.

An alpha particle is composed of He2+ ions?
true or false​

Answers

Answer: The given statement is False.

Explanation:

Alpha particle is a helium nuclei.

Alpha particles are produced when a larger nuclei decays into smaller nuclei in radioactive decay. Alpha particles have mass number and atomic number as 4 and 2 respectively.

General representation of alpha decay :

[tex]^A_Z\textrm{X}\rightarrow ^{A-4}_{Z-2}\textrm{Y}+^4_2\textrm{He}[/tex]

Thus the given statement that alpha particle is composed of [tex]He^{2+}[/tex] ions is False.

The statement of [tex]\rm He^2^+[/tex] ions has formed the alpha particles is true.

Alpha particles are particles that have been similar to the He-4, with the presence of two protons and two neutrons. The alpha particles have the absence of electrons and have been formed during the alpha decay.

[tex]\rm He^2^+[/tex] has been the ion of He with the positive charge indicating the loss of 2 electrons. Thus, in [tex]\rm He^2^+[/tex], there has been 2 protons, 2 neutrons, and 0 electrons.

The atomic configuration of [tex]\rm He^2^+[/tex]has been similar to the alpha particles. Thus, the statement stating, "the alpha particles to be composed of [tex]\rm He^2^+[/tex]ions " is True.

How many molecules are found in 3.4 moles of carbon dioxide?

Please help me asap! :0

Thank you!

Answers

Answer:

One mole of anything has 6.023 x 10^23 molecules.

That would mean 3.4moles of CO2 have 6.023x 10^23 times 3.0.

So that would be2.04782×10^24 molecules in 3.0 moles of C02.

Mole measure the number of elementary entities of a given substance that are present in a given sample. 2.047×10²⁴ molecules are found in 3.4 moles of carbon dioxide.

What is mole?

The SI unit of amount of substance in chemistry is mole. The mole is used to measure the quantity or amount of substance. We know one mole of any element contains 6.022×10²³ atoms which is also called Avogadro number.

Mathematically,

number of molecules of carbon dioxide = number of moles of carbon dioxide ×6.022×10²³ molecules

Number of moles of carbon dioxide=3.4moles

Substituting the values in the above equation we get

number of molecules of carbon dioxide =3.4moles×6.022×10²³ molecules

number of molecules of carbon dioxide =2.047×10²⁴

Therefore, 2.047×10²⁴ molecules are found in 3.4 moles of carbon dioxide.

how many moles is 130g of cocl2

Answers

Answer:

1.3142 mol CoCl2

Explanation:

Well, to answer this we need to find out how many grams are in a single mole of CoCl2. Two find that we need to get the molar mass of CoCl2

Co = 28.0101 g Co per mole

Cl = 35.453 * g Cl per mole

28.0101 + 2 * 35.453 = 98.9161 g CoCl2 per mole

Now, we divide:

130/98.9161 = 1.3142 mol CoCl2

There are 1.31 moles in 130grams of cobalt chloride (CoCl2). Details about how to convert mass to moles can be found below.

How to calculate number of moles?

The number of moles of a substance can be calculated by dividing the mass of the substance by its molar mass.

According to this question, there are 130g of CoCl2.

molar mass of CoCl2 = 28 + 35.5(2) = 99g/mol

moles = 130g ÷ 99g/mol

moles = 1.31 moles

Therefore, there are 1.31 moles in 130grams of cobalt chloride (CoCl2).

What is electronic configuration?

Electronic configuration is defined as the distribution of electrons which are present in an atom or molecule in atomic or molecular orbitals.It describes how each electron moves independently in an orbital.

Knowledge of electronic configuration is necessary for understanding the structure of periodic table.It helps in understanding the chemical properties of elements.

Elements undergo chemical reactions in order to achieve stability. Main group elements obey the octet rule in their electronic configuration while the transition elements follow the 18 electron rule. Noble elements have valence shell complete in ground state and hence are said to be stable.
