The primary function of a scuba regulator is to: Reduce high-pressure gas in the scuba cylinder to a more breathable intermediate pressure. Reduce high-pressure gas in the scuba cylinder to ambient (surrounding) pressure. Provide a diver with a continuous flow of oxygenated air. None of the above.

Answers

Answer 1

Answer:

Reduce high-pressure gas in the scuba cylinder to ambient (surrounding) pressure.

Explanation:

The primary function of a scuba regulator would be to reduce high-pressure gas in the scuba cylinder to ambient pressure.

A scuba regulator is a structure found attached to the scuba cylinder usually carried by scuba divers. The structure regulates the pressure of the breathing gas in the cylinder to a safe level before the gas becomes available for the breathing process of divers.

Usually, the gas in a scuba cylinder is at a high level. Hence, what the regulator does is to bring it down to a level that would be safe for the breathing of the diver.

Love, Piper Rockelle

Answers

Answer:

4.30 × 10²⁰ atoms

Explanation:

You need to find out how many moles you have.  First, convert milligrams to grams.

62.5 mg × (1 g)/(1000 mg) = 0.0625 g

Next, use the molar mass to convert from grams to moles.

0.0625 g ÷ 87.62 g/mol = 7.13 × 10⁻⁴ mol

To convert from moles to atoms, you need to use Avogadro's number (6.022 × 10²³).  Avogadro's number is the number of atoms in a mole.

7.13 × 10⁻⁴ mol × 6.022 × 10²³ atoms/mol = 4.296 × 10²⁰ ≈ 4.30 × 10²⁰ atoms

You will have 4.30 × 10²⁰ atoms of strontium.

The number of Strontium atoms are 4.30 × 10²⁰ atoms

Given:

Mass of Strontium = 62.5 mg × (1 g)/(1000 mg) = 0.0625 g

Molar mass of Strontium = 87.62 g/mol

To find:

Moles of Strontium = ?

Number of moles:

It is defined as given mass over molar mass.

[tex]\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}\\\\\text{Number of moles}=\frac{0.0625 g}{87.62 g/mol }\\\\\text{Number of moles}=7.13 * 10^{-4} mol[/tex]

Avogadro's number is the number of atoms in a mole (6.022 * 10²³)

Conversion of moles into atoms:

[tex]7.13 × 10^{-4} mol * 6.022 * 10^{23} atoms/mol \\\\\text{ Sr atoms}= 4.296 * 10^{20} = 4.30 * 10^{20} atoms[/tex]

Thus, Strontium atoms will be 4.30 × 10²⁰ atoms.

Which fact was most likely discovered between the time of Mendeleev’s table and the time of Moseley’s table that helped Moseley develop his version?

Answers

Answer:

The number of protons in an atom is different than the atom’s total mass.  

Explanation:

Mendeleev knew only that, with some anomalies, the properties of elements varied periodically with their atomic masses.

Moseley's X-ray experiments enabled him to remove these anomalies and to show that the properties of elements varied with their atomic numbers.  

Chadwick later discovered that the mass differences were caused by the presence of neutrons.

156. A solid metal sphere has a volume of 4.2 ft}. The mass
of the sphere is 155 lb. Find the density of the metal
sphere in grams per cubic centimeter.

Answers

Answer:

The answer is

0.59 g/cm³

Explanation:

To find the density of the sphere we use the formula

[tex]Density \: = \frac{mass}{volume} [/tex]

To find the density in g/cm³ first convert the mass into grams and the volume into cm³

For the mass we have

155 lb = 70306.82 g

For the volume

4.2 ft³ = 118930.76 cm³

Substitute the values into the above formula

That's

[tex]Density \: = \frac{70306.82 \: g}{118930.76 \: cm³} [/tex]

We have the final answer as

Density = 0.59 g/cm³

Does Na2 gas posses metallic character? Explain your answer..​

Answers

Explanation:

It contains Na2 molecules and the atoms in this molecule are held together by a purely covalent bond because the electronegativity of the two atoms is identical.Metallic bonding would not kick in until you make clusters of quite a few atoms. Such clusters would likely not be very stable because thermodynamically the larger the clump of material the more stable it gets. So they tend to coalesce until you have chunk of metal.Metallic bonding is in a sense a form of covalent bonding, but it is very collective (delocalized over a great many atoms) and electron deficient (there are more states than electrons to fill them up with, leading to conductive properties. This means that “a metallic bond” is a bit of an oxymoron like a forest with only one tree.

Reply me in comments

Yes, Na2 gas possesses a metallic character.

Does NA contain metallic bonds?

In the stable state, metal sodium functions as an array of Na+ ions which can be surrounded by way of a sea of 3s electrons. However, it would be wrong to consider metal sodium as an ion when you consider that the ocean of electrons is shared by using all of the sodium cations, quenching the nice fee.

Sodium most effective has one valence electron. So, in metallic bonding, it is able to only donate one electron to be delocalized at some point of the structure. In steel bonding, the real bonding is the electrostatic force between the effective cations and the delocalized electrons.

Suppose we want to charge a flask with 2.4 g of sugar. We put the empty flask on a balance and it is determined to weigh 150 g. What is the weight we would expect to see on the balance when we're done adding the sugar?

Answers

Answer:

152.4 g

Explanation:

given that

Weight of sugar = 2.4 g

Weight if empty flask = 150 g

All we have to do is add the weight of the empty flask with the weight of the sugar.

The sugar would be put inside an empty flask. This means that it's weight with that of the empty flask would be their new weight. Thus, the new weight is

New weight = weight of empty flask + weight of sugar

New weight = 150 g + 2.4 g

New weight = 152.4 g

therefore, the new weight is 152.4 g.

I hope this helps you

152.4 g

According to the table, a 23-30 watt CFL provides __________ lumens and is equivalent to a ________ incandescent bulb.

Answers

Answer:

The correct options are;

1. 1,600

2. 100 Watts

A 23-30 watt CFL provides 1,600 lumens and is equivalent to a 100 Watts incandescent bulb

Explanation:

Brightness is measured in lumens and watts measure energy usage therefore with the use of an energy saving light bulb, the same lumination can be obtained at a lower energy usage.

According to a comparison chart for LED Lights vs. Incandescent Light Bulbs vs. Compact Fluorescents (CFLs) from USAI lightening website 23-30 watts CFL has a light output of 1,600 and is therefore produces enough light as a 100 Watts Incandescent Light Bulb

Also according to energy.gov website, CFLs save up to 75% energy such that a 23-30 watt CFL can produce the same illumination as a 100 watt incandescent bulb

Therefore we have, a 23-30 watt CFL provides 1,600 lumens and is equivalent to a 100 Watts incandescent bulb.

A balloon is floating around outside your window. The temperature outside is 31 ∘C , and the air pressure is 0.700 atm . Your neighbor, who released the balloon, tells you that he filled it with 4.10 moles of gas. What is the volume of gas inside this balloon? Express to THREE signficant figures.

Answers

Answer:

the volume of gas inside this balloon = 146.3 L

Explanation:

Given that:

The temperature T = 31 °C = ( 31 + 273.15 )K = 304.15 K

The air pressure P = 0.700 atm

number of moles of gas n = 4.10 moles

Gas constant = 0.0821 L atm/K/mol

The objective is to calculate the volume of the gas inside the ballon.

Using the Ideal gas equation

PV = nRT

V = nRT/P

V = (4.10×0.0821×304.15)/0.700

V = 102.3799/0.700

V = 146.257 L

V = 146.3 L

Thus, the volume of gas inside this balloon = 146.3 L

What is the maximum number of balloons that can be inflated? Report your answer to 1 decimal place. (Remember that 14.71 L of helium at 1.086 atm will remain in the exhausted (empty) cylinder)

Answers

Answer:

The number of balloons is 948.8.

Explanation:

The number of balloons can be calculated as follows:

[tex] N = \frac{V_{f}}{V_{T}} [/tex]

Where:

[tex]V_{f}[/tex]: is the volume at 1.086 atm

[tex]V_{T}[/tex]: is the balloon volume = 2.414 L  

The volume at 1.086 atm can be found using Boyle's law:

[tex] P_{i}V_{i} = P_{f}V_{f} [/tex]

[tex] V_{f} = \frac{P_{i}V_{i}}{P_{f}} = \frac{169.1 atm*14.71 L}{1.086 atm} = 2290.5 L [/tex]

Now, the number of balloons is:

[tex] N = \frac{V_{f}}{V_{T}} = \frac{2290.5 L}{2.414 L} = 948.8 [/tex]

Therefore, the number of balloons is 948.8.

Which of the following factors does not determine the movement of particles in the atoms or molecules of a gas according to the ideal gas law? (3 points) Select one: a. Pressure b. Temperature c. Volume d. Type of particles

Answers

Answer:

type of particles

Explanation:

Considering te definition of idela gas law, the correct answer is option C. type of particles is a  factor that doesn't determine the movement of particles in the atoms or molecules of a gas according to the ideal gas law.

An ideal gas is a theoretical gas that is considered to be composed of point particles that move randomly and do not interact with each other. Gases in general are ideal when they are at high temperatures and low pressures.

The pressure, P, the temperature, T, and the volume, V, of an ideal gas, are related by a simple formula called the ideal gas law:  

P×V = n×R×T

where P is the gas pressure, V is the volume that occupies, T is its temperature, R is the ideal gas constant, and n is the number of moles of the gas. The universal constant of ideal gases R has the same value for all gaseous substances.

Finally, pressure, temperature and volume are factors that determine the movement of particles in the atoms or molecules of a gas according to the ideal gas law.

So, the correct answer is option C. type of particles is a  factor that doesn't determine the movement of particles in the atoms or molecules of a gas according to the ideal gas law.
