On a summer day early in the moming, a balloon is filled with helium when the temperature
MAXImum [283]

Based on the data provided;

  • number of moles of helium gas is 1.25 moles
  • pressure at peak temperature is 259.3 kPa
  • internal pressure is above 256 kPa, therefore, the balloon will burst.
  • pressure should be reduced to a value less than 256 kPa by reducing the temperature

<h3>What is the ideal has equation?</h3>

The ideal gas equation relatesthe pressure, volume, moles and temperature of a gas.

The moles of helium gas is calculated using the Ideal gas equation:

  • PV = nRT

n is the number of moles of gas

R is molar gas constant = 8.314 L⋅kPa/Kmol

P is pressure = 239 kPa

T is temperature = 21°C = 294 K

V is volume = 12.8 L

Therefore;

n = PV/RT

n = 239 × 12.8 / 8.314 × 294

n = 1.25 moles

The number of moles of helium gas is 1.25 moles

At peak temperature, T = 46°C = 319 K

Using P1/T1 = P2/T2

P2 = P1T2/T1

P2 = 239 × 319/294

P2 = 259.3 kPa

The pressure at peak temperature is 259.3 kPa

At 42°C, T = 315 K

Using P1/T1 = P2/T2

P2 = P1T2/T1

P2 = 239 × 315/294

P2 = 256.07 kPa

Since the internal pressure is above 256 kPa, the balloon will burst.

The pressure should be reduced to a value less than 256 kPa by reducing the temperature.

For a price ceiling to be a binding constraint on the market, the government must set it a above the equilibrium price. b below
beks73 [17]

Answer:

B. Below the equilibrium price

Explanation:Price ceiling is the legal price,impose by The Government or Regulatory agencies above which a product should not be sold. It is also a price control mechanism through which the Government and other Regulatory agencies check the excesses of producers and the middle men(Whole sellers and retailers). The price ceiling has to be fixed below the equilibrium price for it to be binding, because businesses are interested mainly for profit maximization.

A chemist wade out 5.96 grams of barium calculate the number of moles of barium she weighed out
PilotLPTM [1.2K]

Answer:

0.04 mol

Explanation:

Given data:

Mass of barium = 5.96 g

Moles of barium = ?

Solution:

Formula:

Number of moles = mass/molar mass

Molar mass of barium = 5.96 g/ 137.33 g/mol

Number of moles = 0.04 mol

Thus the number of moles of barium in 5.96 g are 0.04 moles. The chemist weight out the 0.04 moles .
