Alexandra [31]3 years ago
8 0

Answer:

True is the correct answer.

Explanation:

  • The statement that a prion is an infectious, self-reproducing protein structure is true.
  • prion is an infectious particle and they do not have genetic material.
  • Prion present in the brain region that results in deadly neurodegenerative illnesses in humans and animals.
  • Prions are the self-producing proteinaceous infectious capable of transferring infection in the absence of the nucleic acids.
  • prions enter in the brain by an infection and they emerge from the variation in the gene that encodes the protein and once the prions present in the brain multiply by causing the benign proteins to refold into an abnormal form.

The gases listed are at standard temperature and pressure: · 1 mol of CO2 gas · 1 mol of N2 gas · 2 mol of O2 gas Which statemen
Elena L [17]

Answer : The volume of 1 mole of CO_{2} and N_{2} gases are the same.

Solution: Given,

Moles of CO_{2} = 1 mole

Moles of N_{2} = 1 mole

Moles of O_{2} = 2 mole

Formula used for ideal gas is :

P V = n R T

According to the question, the gases are at standard temperature and pressure. So, the volume of gases only depends on the number of moles. This means that the higher the number of moles, higher will be the volume of gas.

The moles of O_{2} are more than the moles of CO_{2} and N_{2}. So, the volume of O_{2} will be more.

And the moles of CO_{2} and N_{2} are equal. Therefore, their volumes are also equal.

Therefore, the best option is the volume of 1 mole of CO_{2} and N_{2} gases are the same.

PLEASE HELP: 3.01x10^23 molecules of SO3 is how many moles? Please tell me how you got it thank you!
zysi [14]
Divide 3.01x10^23 by the Avogadro's number <span>6.02x10^23

that is 

</span>3.01x10^23 / 6.02x10^23 = 0.5 mol of SO3

Bromine monochloride is synthesized using the reaction
slava [35]

According to ideal gas equation and mole concept, 9.656 g of BrCl is present in the reaction mixture at equilibrium.

<h3>What is ideal gas equation?</h3>

The ideal gas equation is a equation which is applicable in a hypothetical state of an ideal gas.It is a combination of Boyle's law, Charle's law,Avogadro's law and Gay-Lussac's law . It is given as, PV=nRT where R= gas constant whose value is 8.314.The law has several limitations.

Substituting the given values in the ideal as equation, n=PV/RT

∴n=1×190/8.314×273=0.083 moles

mass is calculated as number of moles×molar mass

mass=0.083×115.357= 9.656 g

Thus, 9.656 g of BrCl is present in reaction mixture at equilibrium.
