Answer:

Nitrogen atom is small in size than phosphorus thus the bond between its nucleus and valence electrons are stronger than phosphorus.

Determine the empirical formula of a compound containing 40. 6 grams of carbon, 5. 1 grams of hydrogen, and 54. 2 grams of oxyge

zavuch27 [327]

The empirical formula is C₂H₃O₂

<h3>What is Empirical formula of a compound ?</h3>

The empirical formula is the simplest whole number ratio of elements present in a compound.

The total molar mass of the compound is 118.084 g/mol.

mass of Carbon present = 40.6

mass of Hydrogen present = 5.1 grams

mass of Oxygen present = 2 grams

Moles of C = 40.6/12 = 3.38

Moles of H = 5.1/1.008 = 5

Moles of Oxygen = 54.2/15.999 = 3.38

Ratio of Moles of C to Oxygen is 1 : 1

Ratio of Moles of C to H is 1/1.5

Multiplying each mole fraction by 2

The empirical formula is C₂H₃O₂

Please help with word equations?

Delvig [45]

For the answer to the questions above,

a) Ag2CO3(s) => Ag2O(s)+CO2(g)

b) Cl2(g)+2(KI)(aq) => I2(s)+2(KCl)(aq) (coefficients are for balanced equation) 
net ionic is Cl2(g)+2I- => I2(s)+2Cl-(aq) 

c) I2(s)+3(Cl2)(g)=>2(ICl3)
I hope I helped you with your problem

Not A because

2-Pentyne, an organic compound, is an internal alkyne. It is an isomer of 1-pentyne, a terminal alkyne

Is B because

1) How many grams of carbon dioxide are produced at the same time as 360 g of water vapor in the

shutvik [7]

Answer:

3520 g of CO₂

Explanation:

2C₂H₆ + 70₂ → 4CO₂ + 6H₂O

molar ratio of the above reaction is;

2 : 7 → 4 : 6

2 moles of C₂H₆ will form 6 moles of H₂O

Thus, 1 mole of C₂H₆ will form 3 moles of H₂O

mass of H₂O = 360 g

molecular weight of H₂O = 18 g/mol

molar mass = mass ÷ molecular weight = 360÷18 = 20 moles

Total number of moles of H₂O formed = 6 * 20 moles = 120 moles

Number of moles of C₂H₆ reacted = 120 moles ÷ 3 = 40 moles

molar ratio of C₂H₆ to CO₂ = 1 : 2

Thus, number of moles of CO₂ formed = 2 * 40 moles = 80 moles

molecular weight of CO₂ = 44 g/mol

mass of CO₂ formed = number of moles x molecular weight = 80 * 44 = 3520 g
