A Runner Wants To Run 11.7 Km. Her Running Pace Is 8.0 Mi/hr. How Many Minutes Must She Run?

Answers

Answer 1

Answer:

8 mi = 12.875 km

12.875 /60 m

= 0.21458 km / min

11.7 / 0.21458 = 54.52 min

At 25 oC , the following liquids have density:

water - 0.9982 g/mL; toluene - 0.8669 g/mL; chloroform - 1.4832 g/mL

What mass would a 10.00-mL sample of each of the liquids?

Answers

Answer:

Water- 9.982 grams

toluene-8.669 grams

chloroform - 14.832 grams

Explanation:

the units of density are listed as g/mL. So for every mL of substance you have, you will have that many grams.

Water- .9982g/mL * 10 mL

As you can see, the units of "mL" cancel each other out, leaving just the gram amount of water.

acetaminophen per tablet.If the dose is not to exceed 3.9g of acetaminophen daily,what
is the maximum number of Percocet tablets a patient can take daily?(unit conversion)

Answers

5.56 Rhats The right answer

The maximum number of Percocet tablets a patient can take daily, while staying within the recommended acetaminophen dose of 3.9g, is 12 tablets.

To determine the maximum number of Percocet tablets a patient can take daily without exceeding the recommended dose of 3.9g of acetaminophen, we need to perform a unit conversion.

1. Convert 3.9g to mg (since the amount of acetaminophen per tablet is given in mg):  3.9g = 3900mg

2. Calculate the number of Percocet tablets based on the amount of acetaminophen per tablet:  Each Percocet tablet contains 325mg of acetaminophen.

3. Divide the maximum allowable dose of acetaminophen (3900mg) by the amount of acetaminophen per tablet (325mg) to find the maximum number of tablets: 3900mg / 325mg = 12 tablets

Therefore, the maximum number of Percocet tablets a patient can take daily without exceeding the recommended dose of acetaminophen (3.9g) is 12 tablets.

Elements on the far right of the periodic table are noble gases. They are generally chemically inert.

What are noble gases ?

The noble gases are a group of chemical elements that share several characteristics. They are all monatomic, odorless, and colorless gases with relatively little chemical reactivity under normal conditions. Helium, neon, argon, krypton, xenon, and radioactive radon are the six types of noble gases that are found in nature.

In order of mass, the noble gases are helium, argon, krypton, xenon, and radon. They are known as noble gases because of how beautiful they are and how little they mostly react with anything.

The noble gases are employed to create inert atmospheres, usually for arc welding, to shield specimens and prevent chemical reactions. The substances are utilized in lasers as well as lamps like neon and krypton headlamps. Helium is used in balloons, air tanks for deep sea divers.

Thus, Elements on the far right of the periodic table are noble gases.

Determine the element symbol, mass number, and charge for an atom or ion that has a 51 neutrons, 38 protons, and 36 electrons.

Answers

Answer:

Strontium

Explanation:

To find the element, we need to know the atomic number. There is this rule in chemistry that says that the number of protons and the atomic number are the same. Since we know that there are 38 protons, the atomic number is also 38, leading us to Strontium. Sr -- element symbol.

The mass number is located below the element symbol on a periodic table. The mass number or the atomic mass for Strontium is 87.62 u.

Since there are an uneven amount of protons and electrons, let's subtract the number of electrons from the number of protons to find the difference. 38-36 = 2. (Also, protons are positive and electrons are negative, meaning there are more + than - in the ionic charge). Which means, the atom has a +2 ionic charge.

3

4
50°C to a system at 333 K

Answers

The heat will flow from the system at 40°C to a system at 293 Kelvin.

Flow of temperature

If two systems at different temperatures have contact with each other, heat will flow from the system at 40°C to a system at 293 Kelvin because temperatures moves from hotter body to cold body.

Reason

We know that 293 kelvin is equals to 20° Celsius which is lower than 40° Celsius so the heat energy moves from the body having 40° Celsius temperature to the body having 293 kelvin temperature so we can conclude that the heat will flow from the system at 40°C to a system at 293 Kelvin.

Explanation:

A rectangular box is 10 inches wide, 8 inches long and 6 inches deep. What is its
volume in cubic inches and cubic centimeters? If the box has a mass of 1 kilogram, what is its
density in gram/milliliter?

Answers

The Volume and the density of the box are 480 in³, 7865.81 cm³, 0.127 g/mL

What is volume?

This is the measure of the capacity of substance an object can hold.

To calculate the volume  of the box, we use the formula below

Formula:

V = LWH................. Equation 1

Where:

V = Volume of the boxL = Length of the boxW = Width of the boxH = Height of the box.

From the question,

Given:

L = 10  inchesW = 8 inchesH = 6 inches.

Substitute these values into equation 1

V = 10(8)(6) V = 480 in³

We convert the volume from cubic inches to cubic centimeters using the expression below.

V = (480×16.3871) = 7865.81  cm³

What is density?

Density can be defined as the ratio of the mass and volume of a body.

To calculate the density of the box, we use the formula below.

D = m/V.................. Equation 2

From the question,

Given:

m = 1 kg = 1000 gV = 480 in³ = (480×16.3871) milliliter = 7865.81 mL

Substitute these values into equation 2

D = 1000/7865.81D = 0.127 g/mL

Hence, The Volume and the density of the box are 480 in³, 7865.81 cm³, 0.127 g/mL.

If all of the energy from burning 281.0 g of propane (ΔHcomb,C3H8 = –2220 kJ/mol) is used to heat water, how many liters of water can be heated from 20.0°C to 100.0°C? (Assume that the density of water is 1.00 g/mL)

Answers

This problem is providing us with the mass of propane, its enthalpy of combustion, and the initial and final temperature of water that can be heated from the burning of this fuel. At the end, the result turns out to be 42.27 L.

Combustion:

In chemistry, combustion reactions are based on the burning of fuels by using oxygen and producing both carbon dioxide and water. For propane, we will have:

[tex]C_3H_8+5O_2\rightarrow 3CO_2+4H_2O[/tex]

Hence, we can calculate the heat released from this reaction by using the mass, which has to be converted to moles, and the given enthalpy of combustion:

[tex]Q=281.0g*\frac{1mol}{44.09g}*-2220\frac{kJ}{mol}*\frac{1000J}{1kJ}\\ \\ Q=-1.415x10^7 J[/tex]

Calorimetry:

In chemistry, we can analyze the mass-specific heat-temperature-heat relationship via the most general heat equation:

[tex]Q=mC\Delta T[/tex]

Thus, since Q was obtained from the previous problem, but the sign change because the released heat is now absorbed by the water, one can calculate the mass of water that rises from 20.0°C to 100.0°C with this heat:

[tex]m=\frac{Q}{C\Delta T} =\frac{1.415x10^7J}{4.184\frac{J}{g\°C}(100.0\°C-20.0\°C)}\\ \\m=4.227x10^4g[/tex]

Finally, we convert it to liters as required:

[tex]V=4.227 x10^4g*\frac{1mL}{1.00g}*\frac{1L}{1000mL} \\\\V=42.27L[/tex]
