Answer:
By counting the number of atomic number
Machines that are fairly simple and make working easier
Answer:
d
. H₂SO₄ + 2KOH → K₂SO₄ + 2H₂O
Explanation:
a
. 2HgO → 2Hg + O₂,
It is a decomposition reaction, that HgO is decomposed to give Hg and O.
b
. Na₂SO₄ + BaCl₂ → BaSO₄ + 2NaCl,
It is a double replacement reaction where two salts replaces their cations and anions with each others producing 2 new salts.
c
. Zn + 2AgNO₃ → Zn(NO₃)₂ + 2Ag,
It is a single replacement reaction, that Zn replaces Ag from its salt.
d
. H₂SO₄ + 2KOH → K₂SO₄ + 2H₂O
It is acid-base reaction "neutralization reaction" where H₂SO₄ (acid) reacts with KOH (base) producing K₂SO₄ (salt) and water.
<em>d
. H₂SO₄ + 2KOH → K₂SO₄ + 2H₂O</em>

We assume it as an ideal gas therefore we can use the
ideal gas equation to solve the problem. The ideal gas equation is expressed as
PV = nRT. We are given the volume, temperature and pressure. Therefore, we can solve for the amount of the gas in moles.

n = PV / RT
n = </span>1.00(3L) / (<span>0.08206 atm L/mol K ) 273 K
n = 0.1339 mol
