In the uncatalyzed reaction N2O4 (g) ⇌ 2 NO2 (g) the pressure of the gases at equilibrium are PN2O4 = 0.377 atm and PNO2 = 1.56
larisa86 [58]

Answer:

The pressures will remain at the same value.

Explanation:

A catalyst is a substance that alter the rate of a chemical reaction. It either speeds up the or slows down the rate of a chemical reaction.

While a catalyst affects the rate, it is noteworthy that it has no effect on the equilibrium position of the chemical reaction. A catalyst works by creating an alternative pathway for the reaction to proceed. Most times, it decreases the activation energy needed to kickstart the chemical reaction.

Hence, we know that it has no effect on the equilibrium position. Factors affecting equilibrium position includes, temperature and concentration of reactants and products( pressure in terms of gases).

The reactants and the products here are gaseous, and as such pressure affects the equilibrium position. Now, we have established that the equilibrium position is unaffected. And as such the pressure affecting it does not change.

Thus, we have established that the pressure of the products and reactants are unaffected and as such they remain at their value unaffected.

Explain the relationship between plate tectonics and volcanos
ad-work [718]

Answer:

Plates sliding past each other cause friction and heat. Subducting plates melt into the mantle, and diverging plates create new crust material. Subducting plates, where one tectonic plate is being driven under another, are associated with volcanoes and earthquakes.

What quantum numbers specify these subshells 5s 6p 4d?
shutvik [7]
Quantum numbers are used to describe the location of electrons in atoms. 
Principal quantum number(n) tells which energy shell the electrons reside in.
The first energy shell n = 1, second energy shell n = 2 and it goes on.
Azimuthal quantum number (l) states which orbital the electron is most likely to reside in. the number of orbitals in an energy shell depends on the principal quantum number. number of orbitals are from 0 to  n-1 
If l = 0, s orbital 
   l = 1 , p orbital 
   l = 2, d orbital
in 2nd energy shell the number of orbitals are 0,1 etc.

5s-
Principal quantum number n = 5
Azimuthal quantum number l = 0

6p
Principal quantum number n = 6
Azimuthal quantum number l = 1

4d
Principal quantum number n = 4
Azimuthal quantum number l = 2

Ascorbic acid, of vitamin c (c6h8o6), is an essential vitamin. it cannot be stored by the body and must be present in the diet.
Inessa [10]

Molecular formula of ascorbic acid is C_{6}H_{8}O_{6}

Molar mass of ascorbic acid = (6 * 12 g/mol) + (8 * 1 g/mol) + (6 * 16 g/mol) = 176 g/mol

Converting 500.0 mg of ascorbic acid to moles: We use molar mass of ascorbic acid to convert mass to moles.

500.0 mg * \frac{1 g}{1000 g} *\frac{1 mol}{176 g} =   0.00284 mol

Converting 500.0 mg of ascorbic acid to molecules: The conversion factor used is 1 mole = 6.022*10^{23} molecules

500.0 mg * \frac{1 g}{1000 mg}*\frac{1 mol}{176 g} * \frac{6.022*10^{23}molecules}{1 mol} = 1.71 * 10^{21} molecules
