The number of grams of lead product that would theoretically be produced from the given reaction is; <u><em>Mass of lead product = 23.6 g</em></u>

Potassium iodide reacting with Lead(II) Nitrate would yield the balanced equation;

2KI + Pb(NO₃)₂ = 2KNO₃ + PbI₂

2moles : 1 mole = 2 moles : 1 mole

From online tables;

Molar mass of KI = 166 g/mol

Molar mass of Pb(NO₃)₂ = 331.2 g/mol

We are given;

Mass of KI = 17 g

Mass of Pb(NO₃)₂ = 25 g

Thus;

Number of moles of PbI₂ yielded in order to find the limiting reactant will be;

no of moles of PbI₂ from KI = (17g/166 g/mol) × (1 mole of PbI₂/2 mol of KI)

no of moles of PbI₂ from KI = 0.0512 mols

Similarly;

no of moles of PbI₂ from Pb(NO₃)₂ = (25g/331.2 g/mol) × (1 mole of PbI₂/1 mol of Pb(NO₃)₂)

no of moles of PbI₂ from Pb(NO₃)₂ = 0.0755 moles

We can see that KI produced the least amount of moles. Thus;

Mass = 0.0512 * molar mass of  PbI₂

From tables, molar mass of  PbI₂ = 461 g/mol

Thus;

Mass of lead product = 461 * 0.0512

Mass of lead product = 23.6 g

VashaNatasha [74]

Answer:

See explanation below.

Explanation:

There is no better way to catch up, then actually doing the homework. I spend more time, avoiding the homework, then actually doing it. Imagine that!

I have to put away all games and distractions and resolve to do the work. I never really want to, but have to make myself. My suggestion is resolve to do the homework, promise yourself, and do it.

Hope this Helps!! Have an Awesome Day!!

LekaFEV [45]

Answer:

The answer is 18 m/s

Explanation:

Vo=0 m/s

acceleration a=3m/s

t=6s

V=Vo +a×t

Vo=0

V=a×t

V=3 m/s^2 ×6 s

V=18 m/s

when iron rusts and forms iron oxide, the iron oxide has more mass than the iron. which statement correctly explains this observ
GarryVolchara [31]

The reason why iron oxide has more mass than the iron is because Iron oxide has oxygen atoms, and pure iron does not.

When iron rusts and forms iron oxide, the iron oxide has more mass than the iron. Which statement correctly explains this

observation?

(A)Iron oxide has oxygen atoms, and pure iron does not.

(B)The oxygen atoms in iron oxide have more mass than the iron atoms in pure iron.

(C)The iron atoms in iron oxide have more mass than pure iron.

(D)There are more iron atoms in iron oxide than in pure iron.

When a chemical reaction takes place, other atoms are combined with pure elements to form compounds. This addition of another atom (oxygen) after reaction makes iron oxide formed heavier than pure iron.

Iron oxide is a chemical substance formed when pure iron rusts. The formation of iron oxide is a chemical reaction.

Hence, the correct answer to the question is;  the iron is heavier  because Iron oxide has oxygen atoms, and pure iron does not.
