Draw a structural formula of an alkene or alkenes (if more than one) that undergo acid-catalyzed hydration and without rearrangement give 1-methylcyclohexanol as the MAJOR product. Ignore stereochemistry. If your answer includes more than one alkene, just draw both structures. Do not separate the formulas with + or any other sign.

Answer:

m = 4450 g

Explanation:

Given data:

Amount of heat added = 4.45 Kcal ( 4.45 kcal ×1000 cal/ 1kcal = 4450 cal)

Initial temperature = 23.0°C

Final temperature = 57.8°C

Specific heat capacity of water = 1 cal/g.°C

Mass of water in gram = ?

Solution:

Formula:

Q = m.c. ΔT

Q = amount of heat absorbed or released

m = mass of given substance

c = specific heat capacity of substance

ΔT = change in temperature

ΔT = 57.8°C - 23.0°C

ΔT = 34.8°C

4450 cal = m × 1 cal/g.°C × 34.8°C

m = 4450 cal / 1 cal/g

m = 4450 g

Moving material along certain gradients is necessary for osmosis, diffusion, filtration, and the transport of ions away from similar charges.

Osmosis is the flow of solvent molecules over a semi-permeable membrane from an area of lower concentration to a region of higher concentration Molecules diffuse when they travel from one area of higher concentration to another area of lower concentration The process of filtering involves moving liquid substances through a separating material known as a filter in order to separate solid particles from liquid. Due to the difference in pressures between the solid and liquid substances, this process is made feasible. Because of the difference in electrical potentials between the charges, ions move away from like charges.

Answer:

It loses electrons.

Explanation:

When an atom is oxidized in a redox reaction, it simply loses electrons and the oxidation number increases.

An oxidized atom implies that oxidation has occurred; oxidation can be defined as:

D. It loses electrons

Here's how it works!

Oxidation occurs when an atom, molecule, or ion loses one or more electrons. In the process of oxidation, the oxidation state of the chemical species increases. Originally, the term was used to describe when oxygen caused electron loss in reactions. I hope that helps you!

The equation is ...

  CS₂ +3O₂ ⇒ CO₂ +2SO₂

This indicates 1 molecule of CS₂ combines with 3 molecules of O₂ to produce 1 molecule of CO₂ and 2 molecules of SO₂.

Counting molecules, we see that the original 4 molecules in a 1:3 ratio become 1+2 = 3 molecules. The reactants present are in the necessary 1:3 ratio of CS₂ : O₂, so there are no limitations on the reaction. It can use all of the original molecules to produce ...

molecules of product.

When the reaction completes, there will be 15,000 molecules present.

Explanation:

The concentration of Bovine Hb with absorbance 0.7 at 570 nm has been 2.264 [tex]\mu[/tex]M.

According to Beer's law, the absorbance of the sample can be given by:

Absorbance = Extinction coefficient [tex]\rm \times[/tex] concentration [tex]\times[/tex] path length

The Bovine Hb has the extinction coefficient = 30910 L/mol/cm

The absorbance = 0.7

The path length has been 1 cm.

The concentration of the Bovine Hb can be given as:

0.7 = 30910 [tex]\times[/tex] concentration [tex]\times[/tex] 1

The concentration of Bovine Hb = 2.264 [tex]\rm \times\;10^-^6[/tex] moles/L

The concentration of Bovine Hb = 2.264 [tex]\rm \mu[/tex]moles/L

The concentration of Bovine Hb = 2.264 [tex]\mu[/tex]M.

Answer:

P₂ = 2.60 atm

Explanation:

Given data:

Initial pressure = 2.38 atm

Initial temperature = 25.0 °C

Final pressure = ?

Final temperature = 52.78°C

Solution:

Initial temperature = 25.0 °C (25.0+273 = 298 K)

Final temperature = 52.78°C (52.78+273 = 325.78 K)

According to Gay-Lussac Law,

The pressure of given amount of a gas is directly proportional to its temperature at constant volume and number of moles.

Mathematical relationship:

P₁/T₁ = P₂/T₂

Now we will put the values in formula:

2.38 atm / 298 K = P₂/325.78 K

P₂ = 2.38 atm × 325.78 K  / 298 K

P₂ = 775.35 atm. K /293 K

P₂ = 2.60 atm

Answer:

Yeast is living.

Explanation:

Yeast is a type of fungus used in making bread. Fungus is a group of living organisms.

Answer:

Explanation:

1) The ΔH shows the heat of reaction of the reaction illustrated in the question and the negative sign shows the reaction is an exothermic reaction, meaning heat is released in this reaction. The amount of heat released in this reaction is 851.5 kilojoules per mole of Al₂O₃ produced.

2) The thermal energy of this reaction is however very low when compared to the energy released when 2 moles of protons and 2 moles of neutrons combine to form 1 mole of alpha particles. This is because, the reaction illustrated in the (1) above is a normal chemical reaction while the one that involves the protons and neutrons (as described in this section 2) is a nuclear reaction which involves large amount of energy. Nuclear reactions usually involve way larger amount of energy than ordinary chemical reactions.

Answer:

d) none of the above

Explanation:

The law that describes the relationship between pressure and volume of an ideal gas (under constant temperature and amount of substance) is Boyle's law.

It states that pressure is inversely proportional to the volume. This would mean that a graph of P vs 1/V would be a line.

See the attached picture for a graph of P vs V.

A plot of pressure VS. volume for an ideal gas will result in d) none of the above

[tex]\boxed {\boxed {\sf 53, 346 \ Joules}}[/tex]

Explanation:

We are given the specific heat and change in temperature, so we should use this heat formula:

[tex]q=m C \Delta T[/tex]

where m is the mass, C is the specific heat capacity, and ΔT is the change in temperature.

We know the mass is 150 grams. The specific heat of water is 4.184 J/g °C.

Let's find the change in temperature.

Subtract the initial temperature from the final temperature.

Now we know all the values:

[tex]m= 150 \ g \\C= 4.184 J/ g \ \textdegree C \\\Delta T= 85.0 \textdegree C[/tex]

Substitute them into the formula.

[tex]q=(150 \ g) (4.184 \ J/g \ \textdegree C)(85.0 \textdegree C )[/tex]

Multiply all three numbers together. Note that the grams (g) and degrees Celsius (°C) will cancel out. Joules (J) will be the only remaining unit.

[tex]q=(627.6 \ J/ \textdegree C) ( 85.0 \textdegree C)[/tex]

[tex]q=53346 \ J[/tex]

53,346 Joules of heat are required.
