Astronomers observed that the orbit of Uranus was not uniform. Therefore, they hypothesized the existence of another planet. This is an example of scientific investigation being led by _____.

Inductive Reasoning
Deductive Reasoning

Answers

Answer 1

Answer:

This is an example of scientific investigation being led by inductive reasoning.

Explanation:

Inductive reasoning is the type of reasoning used to make broad generalizations from specific observations. We have certain pieces of data and make conclusions based on them. In the given example, astronomers have made a specific observation - that the orbit of Uranus isn't uniform. Based on that fact, they made a broader conclusion - that there is another planet. There are probably more things that could lead to the same conclusion.

The opposite is deductive reasoning, where a person starts off with a broad generalization and tries to make specific, logical conclusions based on it.

4-How does the concentration of ions in a strong acid differ from a weak acid?

Answers

Strong acids have a higher percentage of H+ ions which means that they have a higher pH and will fully dissociate in water. Whereas weak acids have a lower percentage of H+ ions which means that their pH would be lower and they would only partially dissociate.

A piece of silver is heated and added to a styrofoam cup calorimeter containing 26.0 mL (the density of water is 1 g/mL) of water at 19 oC. The water reaches a maximum temperature of 44 oC after the metal was added. If the specific heat of the silver is 0.240 J/g oC and it started at 93.8 oC

Answers

Answer:

m(Ag) = 227.5g

Explanation:

...what is the mass of the piece of silver?

The heat given for the piece of silver is the same heat that is absorbed for the water, that is:

m(Ag)×C(Ag)×ΔT(Ag) = m(Water)×C(Water)×ΔT(Water)

m is mass of water in solution: 26.0mL = 26g of water

And m(Ag) is the mass of Ag, our incognite.

C is specific heat (0.240J/g°C for Ag), and 4.184J/g°C for water

ΔT is change in temperature (93.8°C - 44°C = 49.8°C) for Ag ad (44°C - 19°C = 25°C)

Replacing:

m(Ag)×C(Ag)×ΔT(Ag) = m(Water)×C(Water)×ΔT(Water)

m(Ag)×0.240J/g°C×49.8°C = 26g×4.184J/g°C×25°C

m(Ag)* 11.952J/g = 2719.6J

m(Ag) = 227.5g

Once the temperature reaches 15,000,000 levels Celsius, nuclear fusion takes location in the center, or core, of the cloud. The high-quality heat given off by means of the nuclear fusion technique motives the gasoline to glow creating a protostar. This is the first step in the evolution of a star.

Practitioners of the branch of alternative medicine known as homeopathy claim that very dilute solutions of substances can have an effect. Is the claim plausible? To explore this question, suppose that you prepare a solution of a supposedly active substance, X, with a molarity of 0.10 molL1 . Then you dilute 10. mL of that solution by doubling the volume, doubling it again, and so on, for 90 doublings in all. How many molecules of X will be present in 10. mL of the fi nal solution? Comment on the possible health benefi ts of the solution.

Answers

Answer:

a. 4.865 × 10⁻⁷ molecules. b. The possible health benefits of the drug might be minimal or non-existent.

Explanation:

a. Since we have 0.10 mol/L and 10 mL of solution, the number of moles in 10 mL of solution is n = CV where C = concentration and V = Volume. C = 0.10 mol/L and V = 10 mL = 0.01 L.

So n = CV = 0.10 mol/L × 0.01 L = 0.001 mol.

Since the initial volume of the solution is 10 mL and doubled, it is 2 × 10 mL = 20 mL. It is doubled again to 2 × 20 mL = 40 mL. It is doubled again to 2 × 40 mL = 80 mL. Our third doubling is thus 80 mL = 2 × 2 × 2 × 10 mL = 2³ × 10 mL. So the volume for our nth doubling is V = 2ⁿ × 10 mL. So four our 90 th doubling, the volume is V = 2⁹⁰ × 10 mL = 2⁹⁰ × 10 mL

Since we have 0.001 mol present, the concentration in this new volume is thus C' = 0.001 mol/2⁹⁰ × 10 mL.

So the number of moles in 10 mL of this solution is thus n = 0.001 mol/(2⁹⁰ × 10 mL) × 10 mL = 0.001/2⁹⁰ mol

To find the number of molecules of X present we use, number of moles, n = number of molecules, N/Avogadro's number of molecules, N'

n = N/N'

N = nN'

= 0.001/2⁹⁰ mol × 6.022 × 10²³ molecules/mol

= 8.078 × 10⁻³¹ × 6.022 × 10²³

= 48.65 × 10⁻⁸

= 4.865 × 10⁻⁷ molecules.

b. Since the number of molecules of X present in 10 mL solution of the final diluted solution is 4.865 × 10⁻⁷ molecules, this shows that the number of molecules of X is very little so, the possible health benefits of the drug might be minimal or non-existent.

Ozone consists of three oxygen atoms (O3) and water consists of two hydrogen atoms and one oxygen atom (H2O). Would you consider both products to be molecules?

Answers

Answer:

Yes, both are molecules

Explanation:

A molecule is the smallest particle of a substance that can exist alone and still retain the chemical properties of that substance.

Molecules are usually made up of two or more atoms of the same or different elements chemically combined together. for example, two atoms of hydrogen will combine to form a molecule of hydrogen gas. Similarly, an atom of hydrogen can combine with an atom of chlorine to form hydrogen chloride gas molecule.

Ozone is a molecule which consists of three atoms of oxygen chemically combined together.

Similarly, water is a molecule composed of two atoms of hydrogen and an atom of oxygen chemically combined together.

What is the pressure of 64 grams of O2 in a 1L container at a temperature of 10°C?

Answers

So PV=nRT
P=?

We know that:
-V=1L
-R=8.314kPa•L/mol•K
-T=10°C (we need to converse °C in K so 10+273) =283K
For n, we know that we have 64g of O2 and were looking for the quantity of mole in these 64g. 1 mole of O2 is 15.999g so 64g would be 4.0mol ((64g • 1mol)/15.999g) so n=4.0

P•1L= 4.0mol • 8.314kPa•L/mol•K • 283K

How are elliptical galaxies different from spiral galaxies?
a. They contain older stars and less gas and dust.
b. They contain younger stars and more gas and dust.
c. They are bigger than spiral galaxies.
d. They are smaller than spiral galaxies.

Answers

Answer:

A. They contain older stars and less gas and dust.

Explanation:

There are three types of galaxies:

elliptical galaxiesspiral galaxieslenticular galaxies

Elliptical galaxies are galaxies shaped like an ellipse, while spiral galaxies consist of a flat, rotating disk that contains stars, gas, and dust, and a central concentration of stars called the bulge.

The difference between elliptical and spiral galaxies is in the amount of gas and dust they contain. Spiral galaxies contain large amounts of gas and dust, which means that new stars are born very often. This makes them brighter than relatively dim elliptical galaxies, which contain less gas and dust. This is why fewer new and brighter stars are born in elliptical galaxies, leaving them with older, dimmer stars.

One litre of hydrogen at STP weight 0.09gm of 2 litre of gas at STP weight 2.880gm. Calculate the vapour density and molecular weight of gas. ​

Answers

Answer:

we know, at STP ( standard temperature and pressure).

we know, volume of 1 mole of gas = 22.4L

weight of 1 Litre of hydrogen gas = 0.09g

so, weight of 22.4 litres of hydrogen gas = 22.4 × 0.09 = 2.016g ≈ 2g = molecular weight of hydrogen gas.

similarly,

weight of 2L of a gas = 2.88gm

so, weight of 22.4 L of the gas = 2.88 × 22.4/2 = 2.88 × 11.2 = 32.256g

hence, molecular weight of the gas = 32.256g

vapor density = molecular weight/2

= 32.256/2 = 16.128g

hence, vapor density of the gas is 16.128g.
