For the purpose we will here use the ideal gas law:

p×V=n×R×T

V= ?
n = 0.5 moleT= 273.15 K (at STP)
p= 101.325 kPa (at STP)
R is  universal gas constant, and its value is 8.314 J/mol×K

Now when we have all necessary date we can calculate the number of moles:
V=nxRxT/p
V=0.5x8.314x273.15/101.325= 11.2 L = 11200 mL

Answer: D.

lara [203]
<h3>Answer:</h3>

It is balanced

<h3>Explanation:</h3>
  • The equation, 2AgI+Na₂S → Ag₂S+2NaI, is balanced because the number of atoms of each element is equal on both sides of the equation.
  • That is, there are two silver atoms, two iodide atoms, two sodium atoms, and one sulfur atom on the right and left the side of the equation.
  • According to the law of conservation of mass, chemical equations should be balanced for the mass of reactants to be equal to that of the products.
