emergency?
Answers
Answer:
Yes, I think.
Explanation:
You cannot make an emergency door if you cannot open it easily. So if there is an emergency you need to be able to go threw it fast. So if there is a fire and you needed to just get out of there through the emergency door, just open it and you can get out.
The gates of an emergency exit must be easily opened in case of an emergency to let people out of the building.

Imine formation from an aldehyde and an amine proceeds reversibly under slightly acidic conditions. The reaction is reversible due to acid-catalyzed hydrolysis of the imine. Imine formation generates an equivalent of water. Given these facts, explain why the imine can be isolated from the reaction mixture.
Answers
Answer:
Imine can be isolated from the reaction mixture as water is continuously removed from the reaction chamber
Explanation:
In this reaction, a non -aqueous solvent is not used (not mentioned in the question). Thus, we can say that there is continuous removal water under suitable reacting conditions and hence the imine formed is left behind.
A gas in a sealed container has a pressure of 125 atm at a temperature of 303 K. If the pressure in the container is increased to 200 atm, what is the new temperature if the volume remains constant?
(Show work pls :)!)
Answers
Answer:
485 K
Explanation:
Step 1: Given data
Initial pressure (P₁): 125 atmInitial temperature (T₁): 303 KFinal pressure (P₂): 200 atmFinal temperature (T₂): ?Step 2: Calculate the final temperature of the gas
Assuming constant volume and ideal behavior, we can calculate the final temperature of the gas using Gay Lussac's law.
P₁/T₁ = P₂/T₂
T₂ = P₂ × T₁/P₁
T₂ = 200 atm × 303 K/125 atm = 485 K

C6H1206(s) + 60,(g) <—>6C02(g)+ 6H2O(g)
Answers
Answer: Keq= [CO2]^6[H2O]^6/ [O2]^6
Explanation:
The correct equilibrium constant expression for this equation C6H1206(s) + 60,(g) <—>6C02(g)+ 6H2O(g) will be
keq = 6[co2] 6[h2o] / [c6h1206] 6[o].
What is the equilibrium constant?All reactions tend towards the state of chemical equilibrium. It is the point at which both the forward process and the reverse process are taking place at the same rate.
Since the forward and reverse rates are equal, hence the concentrations of the reactants and products will be constant at the equilibrium state. Here, it is important to remember that even though the concentrations are constant at equilibrium.
The double half-arrow sign we use for writing the reversible reaction equations. It is represented as ⇌ a sign of equilibrium.
therefore, the correct equilibrium constant expression will be C6H1206(s) + 60,(g) <—>6C02(g)+ 6H2O(g)

A gas cylinder initially contains 463 L of gas at a pressure of 159 atm. If the final volume of gas is 817 L, what is the final pressure?
Answers
Answer:
The final pressure is 90.1 atm.
Explanation:
Assuming constant temperature, we can solve this problem by using Boyle's Law, which states:
P₁V₁=P₂V₂Where in this case:
P₁ = 159 atmV₁ = 463 LP₂ = ?V₂ = 817 LWe input the given data:
159 atm * 463 L = P₂ * 817 LAnd solve for P₂:
P₂ = 90.1 atmThe final pressure is 90.1 atm.

The most common experimental technique to perform elemental analysis is combustion analysis, where a sample is burned in a large excess of oxygen and the combustion products are trapped in a variety of ways. A 99.99% pure, 0.4808 g sample containing only carbon, hydrogen, and nitrogen is subjected to combustion analysis, resulting in the formation of 0.6859 g CO2, 0.6973 g H2O, and 0.4646 g NO. What is the empirical formula of the sample
Answers
Answer:
C₂H₅N₂
Explanation:
In the combustion analysis, all NO comes from the nitrogen of the sample, that means:
Moles NO = Moles N in the sample
In the same way:
Moles CO2 = Moles C in the sample
Moles H2O = 1/2 moles H in the sample
To solve this problem we must convert the mass of each gas to moles in order to find the moles of each atom. The empirical formula is the simplest whole number ratio of atoms presents in the molecule:
Moles NO = N -Molar mass: 30g/mol
0.4646g * (1mol / 30g) = 0.01549 moles N
Moles CO2 = C -Molar mass: 44.01g/mol-
0.6859g * (1mol / 44.01g) = 0.01559 moles C
Moles H2O = 1/2moles H -Molar mass: 18.02g/mol-
0.6973g * (1mol / 18.02g) = 0.03870 moles H
The ratio of atoms is -Dividing in the low number of moles = moles N-:
C = 0.01559 / 0.01549 = 1
N = 0.01549 / 0.01549 = 1
H = 0.03870 / 0.01549 = 2.5
Twice this ratio of atoms -Because empirical formula must be given only with whole numbers:
C = 2
N = 2
H = 5
The empirical formula is:
C₂H₅N₂3.

Solid A at 80°C is immersed in liquid B at 60°C. Which statement correctly describes the energy changes between A and B?
Answers
Heat energy will be released by solid A which will then be absorbed by liquid B.
What is heat energy?
These little particles vibrate back and forth or run into each other constantly. All matter contains a type of energy known as heat (or thermal) energy, which is produced by the movement of particles.
Particle energy increases with temperature. It is possible for some of this energy to be transferred to cooler particles. For instance, in the gas state, when a fast-moving particle strikes a slower-moving particle, some of the energy from the collision is transferred to the slower-moving particle, increasing its speed.
A region of high energy will gradually spread throughout the material as a result of billions of moving particles colliding with one another until thermal equilibrium is established.
Therefore, heat energy will be released by solid A which will then be absorbed by liquid B.

Answers
Answer:
The volume is 22.66 mL
Explanation:
D = 22.1 g/cm³, M = 523.1 g, V = ? mL
For Volume
Density = Mass ÷ Volume
Volume = Mass ÷ Density
V = M ÷ D
V = 523.1 g ÷ 22.1 g/cm³
V = 23.66 cm³
Now, 1 cm³ = 1 mL
So,
V = 22.66 mL
Thus, The volume is 22.66 mL

E is the extinction coefficient = 18000M⁻¹cm⁻¹

3 Zn + 2 H3PO4 → 3 H2 + Zn3(PO4)2
How many grams of Zn are needed in order to produce 0.15 g of H2?
Answers
Answer: 4.87 g
Explanation:
We know that for every 3 moles of zinc that are consumed, 3 moles of hydrogen are produced (we can reduce this to the number of moles of zinc consumed = moles of hydrogen produced)
We know that the formula mass of hydrogen is 2(1.00794)=2.01588 g/mol, so in 0.15 g, there is about 0.15/2.01588 = 0.074409191023275 moles.
This means that about 0.074409191023275 moles of zinc are needed, and since the atomic mass of zinc is 65.409 g/mol, the answer is (0.074409191023275)(65.409)=4.87 g

1.2*10^24 molecules of CF4
Explanation:
the molar mass of cf4 is 88.0043 g/mol
176/88.0043 = 2 moles of CF4
Then multiply by avogadro's number (6.022*10^23) to get the number of molecules
2*6.022*10^23 = 1.2*10^24 molecules of CF4
There are 1.204 × 10²⁴ molecules of carbon tetrafluoride in 176 grams of CF4.
HOW TO CALCULATE NUMBER OF MOLECULES:
The number of molecules in a substance can be calculated by multiplying the number of moles in the substance by Avogadro's number:no. of molecules = no. of moles × 6.02 × 10²³The number of moles in CF4 can be calculated as follows:moles of CF4 = mass of CF4 ÷ molar mass of CF4. Molar mass of CF4 = 12 + 19(4)Molar mass of CF4 = 88g/molmoles of CF4 = 176g ÷ 88g/molmoles of CF4 = 2molNo. of molecules = 2 × 6.02 × 10²³no. of molecules = 12.04 × 10²³no. of molecules = 1.204 × 10²⁴ Therefore, there are 1.204 × 10²⁴ molecules of carbon tetrafluoride in 176 grams of CF4.Learn more at: https://brainly.com/question/11815186?referrer=searchResults
