A geologist was looking at a new

mineral they found. The mineral

sample was gray, non-metallic, had

density of 3.8 g/mL, and a volume

of 48.3 mL

Of the observed properties listed

below, which is considered to be an

extensive property?

A Gray

B Metallic

C Density

Answers

Answer:

D. Volume

Explanation:

Properties mentioned in the question;

colour = gray

Nonmetallic

Density = 3.8 g/mL

Volume = 48.3 mL

Of the mentioned, which is extensive ?

Extensive properties are those properties that are proportional to the amount of substance present.

The correct option is D. Volume. The other properties do not change with increasing or decreasing amount of the mineral

There are 20.8 moles of propanol

Further explanation  

The mole is the number of particles(molecules, atoms, ions) contained in a substance  

1 mol = 6.02.10²³ particles

Can be formulated

N=n x No

N = number of particles

n = mol

No = Avogadro's = 6.02.10²³

1.2 x 10⁵ molecules of propanol

Green light has a frequency of 6.01x10^14Hz what is the wavelength

Answers

Answer:

λ  = 0.5×10⁻⁶ m

Explanation:

Given data:

Frequency of light = 6.01 ×10¹⁴ Hz

Wavelength of light = ?

Solution:

Formula:

Speed of light = wavelength × frequency

Speed of light = 3×10⁸ m/s

3×10⁸ m/s = λ × 6.01 ×10¹⁴ Hz

λ  = 3×10⁸ m/s / 6.01 ×10¹⁴ Hz

        Hz = 1/s

λ  = 0.5×10⁻⁶ m

Which of the following does not apply to water molecules?

Water molecules are polar
Water has cohesive properties
Water is less dense as a solid than a liquid
Water is not a very good solvent

Answers

Answer:

It is the last one.

Explanation:

Water molecules are polar, they have cohesive properties, and water is less dense when it is solid than when it is a liquid, that is why ice floats in liquid water. However, water is a very good solvent, it can dissolve many solids, including sugar, salt, and other hydrophilic substances.

Las disoluciones comerciales de HCl (PF = 36.5 g/mol) típicamente son 39.0% P/P de este ácido en agua. Determine la molalidad de la disolución del HCl si la densidad de la misma es igual a 1.20 g/ml.

Answers

The translation of the question is

Commercial solutions of HCl (MP = 36.5 g / mol) are typically 39.0% W / W of this acid in water. Determine the molality of the HCl solution if its density is equal to 1.20 g / ml.

Answer:

Molality is 17.51 molal

Explanation:

We are given 39% w/w of HCl, this means for every 100g of this solution we have 39g of HCl in it.

to ease the calculation we assume we have 1L(1000ml) of this solution is present.

Density = mass /volume

1.20 = mass/1000

mass = 1200 g of solution

and we are given that 39% of this solution is will contain HCl

so

1200 * 39/100 = 468g of HCl present

no of moles of HCl = 468/36.5 = 12.82moles

mass of solution = mass of water + mass of acid

mass of water = mass of solution - mass of acid

Mass of water = 1200 - 468 = 732g of water

Molality = moles /masss of water in kg

             = 12.82 *1000/732  =17.51molal

When naming acids the prefix hydro- is used when the name of the acid anion ends in___

Answers

Answer:

hydrochloric acid

Explanation:

These anions usually have the ending “-ide.” As acids, these compounds are named starting with the prefix “hydro-,” then adding the first syllable of the anion, then the suffix “-ic.” For example, HCl, which is hydrogen and chlorine, is called hydrochloric acid. More complex acids have oxygen in the compound.

One isotope of oxygen differs from another isotope of oxygen in *

Answers

Each isotope of Oxygen has a different number of neutrons

Further explanation

The elements in nature have several types of isotopes

Atomic mass is the average atomic mass of all its isotopes

Isotopes are atoms has the same number of protons but has a different number of neutrons.

So Isotopes are elements that have the same Atomic Number (Proton)

Some of the isotopes of oxygen are:

[tex]\tt _8^{16}O,_8^{17}O,_8^{18}O[/tex]

Each isotope has 8 protons and 8 electrons but has a different number of neutrons

For O-16: number of neutrons = 16-8 = 8

For O-17: number of neutrons = 17-8 = 9

For O-18: number of neutrons = 18-8 = 10
