Explain in detail how low density polyethylene is made​

Answers

Answer 1

Answer:

Low-density polyethylene is manufactured by the process of the polymerization of ethylene at very high temperatures in a tubular reactor. In this tubular reactor, high-pressure polymerization allows further copolymerization of ethylene with polar co-monomers. The tubular process has an advantage over autoclave process.

What is the pressure inside a container of 3 moles of gas with a volume of 60 Liters at a temperature of 400 K?


I just need the answer not a link please :)

Answers

1.64 atm

PV = nRT —> P = nRT / V

n = 3 moles
R = 0.08206 L atm / mol K
T = 400 K
V = 60 L

P = (3)(0.08206)(400) / 60 = 1.64 atm

Ali says the climate of a town is rainy because it is raining outside today. Is she correct? In one or two sentences, explain why Ali is or is not correct about the climate of the town.

Answers

Answer:

Ali is incorrect.

Explanation:

Ali is wrong because the climate is a study of the weather pattern over a long period of time. You cannot look outside one day and determine the climate because the climate is long-term.

She could say the weather is rainy, because that is short term, but not the climate.

WILL AWARD BRAINLIEST! I NEED HELP PLEASE! Match the states of matter for each of the five lines below.

Answer:

see explanations

Explanation:

The graphic is the heating curve for water. Note that it is divided into 5 distinct heat flow segments. The segments with changing slopes are single phase segments with changes in temperature values. From left to right segment A is solid ice being warmed to it's melting point. Segment B is the melting segment in which 2 phases are in contact (solid + liquid). Note that addition of heat does not change the temperature. Segment C is warming of the liquid (single phase) up to its boiling point. At the boiling point the liquid begins to pass into the gas phase and again 2 phases are in contact; i.e., liquid & gas. Note again when two phases are in contact no temperature change occurs. Finally, segment E is the heating of the pure, single phase gas.

In summary ...

Segment A => heating single phase (solid) ice up to melting pt.

Segment B => melting of ice => 2 phases in contact (s & l) ΔT = ∅.

Segment C => heating single phase (liquid) water up to boiling pt.

Segment D => boiling of liquid => 2 phases in contact (l & g). ΔT = ∅.

Segment E => heating single phase (steam) up to desired temperature.

For what it's worth, the equation for the segments that show increasing temperature values is q = mcΔT (m= mass, c = specific heat & ΔT temp change.

The segments with zero slopes (horizontal lines) are defined by equations  q = m·ΔHₓ where m = mass & ΔHₓ = heat of fusion (a constant = 335 j/g). The same is true for the line at 100°C where q = m·ΔH(v) where m = mass & ΔH(v) is the heat of vaporization (a constant = 2259 j/g.

Calculations involve calculating the amount heat transfer for each segment individually and then adding the heat values to obtain the total heat transfer.

Answer:

Ingles porfavor

Explanation:

The calorimeter is used to measure the heat of the system. The enthalpy of the combustion of magnesium cannot be measured by the calorimeter as it could melt the cup.

What is a coffee cup calorimeter?

A coffee cup calorimeter is a styrofoam cup that contains partially filled water and is dipped with a thermometer. The reaction occurs in the water of the cup and hence differs from the bomb calorimeter.

The enthalpy of combustion is rigorous which can dissolve the polystyrene cup and hence is not used. They are better insulators than a beaker. The coffee cup calorimeter is not used to measure the enthalpy of hydrogen and oxygen as they involve gases that can escape the cup.

It is a telling fact about our language and our culture that someone dedicated to pursuit of knowledge is compared to a freak biting the head off a live chicken.Even at a prestigious academic institution like Harvard, anti-intellectualism is rampant: Many students are ashamed to admit, even to their friends, how much they study. Although most students try to keep up their grades, there is a minority of undergraduates for whom pursuing knowledge is the top priority during their years at Harvard. Nerds are ostracized while athletes are idolized.The same thing happens in U.S. elementary and high schools. Children who prefer to read books rather than play football, prefer to build model airplanes rather than get wasted at parties with their classmates, become social outcasts. Ostracized for their intelligence and refusal to conform to societys anti-intellectual values, many are deprived of a chance to learn adequate social skills and acquire good communication tools.Enough is enough.Nerds and geeks must stop being ashamed of who they are.
