Mole ratio compares the subscripts of two compounds in a balanced reaction.

DerKrebs [107]

Answer:

The correct option is FALSE

Explanation:

Mole ratio is the ratio of the number of moles of two compounds in a balanced chemical reaction. Number of moles of a compound in a chemical reaction is the number written before the compound.

For example, the mole ratio of Iron (Fe) and water (H₂O) in the equation below is 3:4

3Fe + 4H₂O ⇒ Fe₃O₄ + 4H₂

Thus, mole ratio does not compare subscripts of compounds.

For the following reaction, provide the missing information

jenyasd209 [6]

Answer:

19. Option B. ⁰₋₁B

20. Option D. ²¹⁰₈₄Po

Explanation:

19. ²²⁸₈₈Ra —> ²²⁸₈₉Ac + ʸₓZ

Thus, we can determine ʸₓZ as follow:

228 = 228 + y

Collect like terms

228 – 228 = y

y = 0

88 = 89 + x

Collect like terms

88 – 89 = x

x = –1

Thus,

ʸ ₓZ => ⁰₋₁Z => ⁰₋₁B

²²⁸₈₈Ra —> ²²⁸₈₉Ac + ʸₓZ

²²⁸₈₈Ra —> ²²⁸₈₉Ac + ⁰₋₁B

20. ᵘᵥX —> ²⁰⁶₈₂Pb + ⁴₂He

Thus, we can determine ᵘᵥX as follow:

u = 206 + 4

u = 210

v = 82 + 2

v = 84

Thus,

ᵘᵥX => ²¹⁰₈₄X => ²¹⁰₈₄Po

ᵘᵥX —> ²⁰⁶₈₂Pb + ⁴₂He

²¹⁰₈₄Po —> ²⁰⁶₈₂Pb + ⁴₂He

How many moles of N are in .235g of N2O

makkiz [27]

Given the molar mass of Nitrogen is 14.01g/mol you can use that to solve for the moles of nitrogen.
0.235g(1mol/14.01g) = .0168 moles.
