Definition of chemical change

Answers

Answer:

Chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. These processes are called chemical reactions and, in general, are not reversible except by further chemical reactions.

Convert Fahrenheit temperature
to Kelvin scales​

Answers

°C + 273.15 = K. The basic formula for converting Fahrenheit into Celsius is (°F − 32) × 5/9 = °C. To convert Fahrenheit degrees into Kelvins, (°F − 32) × 5/9 + 273.15 = K.

Answer:

K = (F – 32)5/9 + 273.15

Explanation:

You basically convert Fahrenheit to Celcius and then to Kelvin

Here's the entire formula:

K = (x °F – 32)5/9 + 273.15

Draw the structures of organic compounds A and B. Indicate stereochemistry where applicable The starting material is ethyne, a carbon carbon triple bond where each carbon is bonded to a hydrogen. Step 1 is N a N H 2 followed by 1 equivalent of C H 3 C H 2 C H 2 B r to form compound A. Compound A reacts with hydrogen and lindlar's catalyst to form compound B. COmpound B reacts with H 2 O and H 3 O Plus to form a 5 carbon chain with a hydroxy substituent on carbon 2.

Answers

Answer:

See explanation below

Explanation:

In this case we have the starting reactant which is the ethine, In the first step reacts with NaNH₂, a strong base. This base will substract the hydrogen from one of the carbon of the ethine, and form a carbanion. This will react with the propane bromide, displacing the bromine and forming a 5 carbon chain with the triple bond on the carbon 1 and 2.

In the second step, reacts with the lindlar catalyst to do a reduction, and form a double bond between carbon 1 and 2. In essence, compound A is similar to compound B.

Finally B reacts with water in acid and makes a addition reaction, and form an alcohol.

The whole process can be seen in the picture below.

A 1,900-m3 water tower has been cleaned with a chlorine solution. The vapors of chlorine in the tower exceed allowable concentrations for the work crew to enter and finish repairs. If the chlorine concentration is 15 mg/m3 and the allowable concentration is 0.0015 mg/L, how long must the workers vent the tank with clean air flowing at 2.35 m3/s

Answers

Answer:

t = 1862 s

Explanation:

To do this, we need first to determine the theorical detention time, which can be determined with the following expression:

t₀ = ∀/Q  (1)

Where:

t₀: detention time

∀: Volume of the fluid in the reactor

Q: Flow rate in the reactor

With this time, we must use the following expression to determine the time that the workers will take to vent the tank:

C = C₀ e^(-t/t₀)   (2)

From here, we must solve for time t, and the expression will be:

t = ln(C₀/C) * t₀   (3)

Now that we know the expression to use, let's solve for t. Using (1) to determine the detention time, ∀ is 1900 m³, and Q is 2.35 m³/s so:

t₀ = 1900 / 2.35 = 808.51 s

Now, let's solve for the time t. C will be 0.0015 mg/L (or 1.5 mg/m³ cause in 1 m³ we have 1000 L) and C₀ 15 mg/m³:

t = ln(15/1.5) * 808.51

t = 1861.66 s or simply 1862 s

Danielle is designing a system to help race cars slow safely and rapidly at her local racetrack. The racetrack is a straight, 1,000-meter stretch of asphalt. Half of the track is devoted to races and the other half is designed to let cars decelerate after crossing the finish line.

Danielle has designed a pair of small parachutes that are automatically released out the back of a car once it crosses the finish line. When her system works properly, the race car driver does not need to apply the brakes to bring the car to a stop before running out of track.

When Danielle tests a prototype of her design, it brings a race car to a stop 275 meters behind the finish line. After taking some measurements, she decides that her design causes the driver to experience too much force. To correct this, she could
A.
make the parachutes larger in order to increase the drag forces on the car and bring it to a stop 200 meters after crossing the finish line.
B.
add a third parachute in order to increase the drag forces on the car and bring it to a stop 175 meters after crossing the finish line.
C.
make the parachutes smaller in order to decrease the drag forces on the car and bring it to a stop 400 meters after crossing the finish line.
D.
remove one of the parachutes in order to decrease the drag forces on the car and bring it to a stop 550 meters after crossing the finish line.

Answer:

The answer is C

Which substances are released during cellular respiration?

Use complete sentences to explain how the mass of oxygen is conserved during cellular respiration.

Answers

The formula for cellular respiration is the opposite of photosynthesis in a way of remembering it. Glucose (C6H12O6) + oxygen to break it down makes 2 waste products. 6H2O (water) and 6CO2 (carbon dioxide) The most important product would be ATP that the cells use for energy, but I am assuming you wanted to know about what is released. Example: When you exercise, you breath in more oxygen which breaks down more glucose which makes more ATP. That’s why you feel tired. And you start to breath out more and release more CO2 as a waste product being released. Hope this helped!

An industrial synthesis of urea obtains 87.5 kg of urea upon reaction of 68.2 kg of ammonia

with 105 kg of carbon dioxide. Determine the limiting reactant, theoretical yield of urea and percent yeild for the reaction​

Answers

Answer:

NH₃ is the limiting reactant.Theoretical yield = 120 kg% yield = 72.9 %

Explanation:

2NH₃ (aq) + CO₂ (aq) → CH₄N₂O (aq) + H₂O (l)

First we convert the given masses of reactants to moles, using their respective molar masses:

68.2 kg NH₃ ÷ 17 kg/kmol = 4.01 kmol NH₃105 kg CO₂ ÷ 44 kg/kmol = 2.39 kmol CO₂

2.39 kmol of CO₂ would react completely with (2.39 * 2) 4.78 kmol of NH₃. There are not as many NH₃ kmoles so NH₃ is the limiting reactant.

We calculate how much urea would form with a 100% yield, using the moles of limiting reactant:

4.01 kmol NH₃ * [tex]\frac{1kmolCH_4N_2O}{2kmolNH_3}[/tex] = 2.00 kmol CH₄N₂O

We convert that amount to kg:

2.00 kmol CH₄N₂O * 60 kg/kmol = 120 kg CH₄N₂O

Finally we calculate the percent yield:

87.5 kg / 120 kg * 100% = 72.9 %

Which statement correctly describes atoms? *
-Atoms combine to make all the substances on Earth.
-Atoms of all substances have the same chemical properties.
-Atoms are easily destroyed when matter is cooled or heated.
-Atoms come in different sizes, but most are visible using a simple hand lens.

Answers

Answer: Atoms combine to make all the substances on Earth.

Explanation:

Atom is a smallest entity of any matter. The atoms of different elements combine together in order to form new substances. The atoms have electrons, neutrons, as well as protons. The atoms are combined by the chemical bond. When two or more atoms combine they form a molecule. The molecules combine to form compound. Atoms cannot be broken into sub parts. The two atoms of hydrogen and one of oxygen forms water which is an essential liquid on planet earth. Other substances like carbon dioxide, coal, and sodium chloride.

B. It decreases orientation requirements of the molecules.
C. It increases the equilibrium constant for the reaction.
D. It decreases the activation energy of the reaction.

Answers

Answer:

B

Explanation:

"The temperature increases cause the rate of a reaction to increases the kinetic energy"

What is rate of reaction?

The reaction rate, also known as the rate of reaction, is the rate for which a chemical reaction occurs, and is proportional to increase in product concentration per unit time and the reduction in reactant concentration per unit time. The rate of reaction varies greatly.

What is kinetic energy?

An object's kinetic energy is the energy it has as a result of its motion. It is the amount of work required to push a body of a given mass from rest to a certain velocity. The body keeps its kinetic energy gained during acceleration unless that speed changes.
