Answer:

Explanation:

Lead Monoxide: PbO

Nitric Acid: HNO3

PbO + 2 HNO3 ---> Pb(NO3)2 + H2O

4 0

Answer:

Explanation:

mono mean single so lead monoxide is PbO

nitric acid is HNO3

both Pb n O are double-charged while H n NO3 are single

so balanced eqn is:

PbO + 2HNO3 -> Pb(NO3)2 + H2O

Answer:

1. Mass of New atom = 208

2. Atomic number of the new atom is 82

3. Symbol of the new atom is Pb

Explanation:

²¹²₈₄Po —> ⁴₂He + ᴬZX

1. Determination of the mass A of the new atom.

212 = 4 + A

Collect like terms

212 – 4 = A

208 = A

A = 208

Therefore, the mass of the new atom is 208

2. Determination of the atomic number of the new atom.

84 = 2 + Z

Collect like terms

84 – 2 = Z

82 = Z

Z = 82

Therefore, the atomic number of the new atom is 82

3. Determination of symbol of the new atom

The atomic number of the new atom is 82. Comparing the atomic number of the new atom (i.e 82) with those in the periodic table, the new atom is Lead.

Lead has a symbol of Pb

Thus,

Mass of new atom (A) = 208

Atomic number of new atom (Z) = 82

Symbol of new atom (X) = Pb

Therefore,

ᴬZX = ²⁰⁸₈₂Pb

If 5.58 g of iron reacts with sulfur to produce 8.79 g of iron sulfide, what is the mass of reacting sulfur? A) 3215 B) 14:37 C)
gogolik [260]

Answer: A) 3.21 g

Explanation:

According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side.

Fe+S\rightarrow FeS

We are given:

Mass of iron = 5.58 g

Mass of iron sulphide = 8.79 g

Mass of sulphur = x g

Total mass on reactant side = 5.58 + x

Total mass on product side = 8.79 g

Applying law of conservation of mass, we get:

5.58+x=8.79\\\\x=3.21g

Hence, the mass of reacting sulfur is 3.21 g.
