Which of the following is the correct set-up for the problem: How many grams of water will be produced from 3.2 moles of oxygen
suter [353]

Option C is the correct set of the problem for mass of water produced by 3.2 moles of oxygen and an excess ethene.

<h3>Reaction between oxygen and ethene</h3>

Ethene (C2H4) burns in the presence of oxygen (O2) to form carbon dioxide (CO2) and water (H2O) along with the evolution of heat and light.

C₂H₄  + 3O₂   ----- > 2CO₂ + 2H₂O

from the equation above;

3 moles of O₂ ---------> 2(18 g) of water

3.5 moles of O₂ ----------> x

x = 3.2 \times [\frac{2 \ moles \ H_2O}{3 \ moles \ O_2}  ] \times[ \frac{18.02 \ g \ H_2O}{1 \ mole \ H_2O} ]

Thus, option C is the correct set of the problem for mass of water produced by 3.2 moles of oxygen and an excess ethene.

What is the average atomic mass of the element?
morpeh [17]

The average atomic mass of element X is 14.007 u.

The average atomic mass of X is the <em>weighted average</em> of the atomic masses of its isotopes.

We multiply the atomic mass of each isotope by a number representing its <em>relative importance</em> (i.e., its % abundance).

Thus,  

0.996 36 × 14.003 u =13.952 03 u

0.003 64 × 15.000 u = <u>0.054 60 u</u>

__________TOTAL = 14.007     u

Which value would be required to estimate the lattice energy for the hypothetical ionic compound MgH2?
Sonja [21]
D, the energy of formation is equal to the dissociation. so from magnesium ions and Hydrogen ions, when they form the lattice energy is equal to formation-dissociation, as they aren't going to dissociate (fixed in lattice) the formation should be the same as the the overall lattice energy.

julsineya [31]

Answer:

3N2Cl4 + 3CH4--> 3CCl4 + 3N2 + 6H2

This simplifies to:

N2Cl4 + CH4 --> CCl4 + N2 + 2H2

What is the molarity of a solution that contains 9.63 grams of HCl in 1.5 liters of solution? 1 H 1.01 Hydrogen 17 Cl 35.45 Chlo
madam [21]
Hey there !

Molar mass HCl :

HCl =1.01 + 35.45 => 36.46 g/mol

Number of moles ( solute) :

n = m / mm

n = 9.63 / 36.46

n = 0.2641 moles

Therefore :

M = moles / volume ( L )

M = 0.2641 / 1.5

=> 0.176 M
