Calculate the energy required to produce 9.00 mol of Cl₂O₇ based on the following balanced equation. 2Cl₂(g) + 7O₂(g) + 130 kcal

→ 2Cl₂O₇
For 2 mol you need 130 kcal, so how much would you need for 9.00 mol?

9.00 kcal
65 kcal
585 kcal
1,170 kcal

Answer:

585 kcal .

Explanation:

  • From the balanced equation:

<em>2Cl₂(g) + 7O₂(g) + 130 kcal → 2Cl₂O₇.</em>

130 kcal are needed to produce 2 mol of Cl₂O₇.

<em><u>Using cross multiplication:</u></em>

130 kcal are needed to produce → 2 mol of Cl₂O₇.

??? kcal are needed to produce → 9 mol of Cl₂O₇.

<em>∴ The energy required to produce 9.00 mol of Cl₂O₇ </em>= (130 kcal)(9 mol)/(2 mol) = <em>585 kcal.</em>

marishachu [46]

Answer:

3.00 × 10¹¹ g

Explanation:

According to the United States Department of Agriculture (USDA), Texas had 4,015,000 beef cows in 2013. One beef cow produces 205 grams of methane per day. The methane produced by the beef cows in Texas per day is:

4,015,000Cow \times \frac{205gCH_4}{cow \times day} = \frac{8.23 \times 10^{8}gCH_4}{day}

Each year has 365 days. The methane produced by the beef cows in Texas per year is:

\frac{8.23 \times 10^{8}gCH_4}{day} \times \frac{365day}{1y} = 3.00 \times 10^{11}gCH_4

Which of the following molecules or ions is polar? (20 POINTS)
taurus [48]

<u>For NO3- molecule(fig.1)</u>

1.  Bonds are created between elements with different electronegativity, most bonds would be polar. Bonds in NO3 are polar.

2. In the geometry of the molecule  bond polarities cancel out each other (since it is a vector) so NO3- ion molecule is non polar

3.   Nitrate (NO3-)ion  geometry would be trigonal planar

<u>For CCl4 molecule(fig.2)</u>

1. Bonds are created between elements with different electronegativity, most bonds would be polar. Bonds in CCl4 are polar.

2. It is a completely symmetrical molecule.

3.Carbon is the centre of CCl4 have four covalent bonds and it has no lone pairs. They are all equidistant the C-Cl bond polarities cancel out. So CCl4 molecule is non polar

<u>For NH3 molecule(fig.3)</u>

1. Bonds are created between elements with different electronegativity, most bonds would be polar. Bonds in NH3 molecule are polar.

2.  it has a pyramidal structure.

3. the individual N-H bond dipoles don't cancel out. This dipole moment for the molecule indicates that NH3 is a polar molecule

<u>For SF6 molecule(fig.4)</u>

1.F is more electronegative than S. So the bonds are polar.

2. The symmetry of the molecule is  symmetrical so that the dipole moments of bonds cancel correspond so the molecule is non-polar.

3. it has octahedral structure

Fe(NO3)2 not sure how to get the oxidation numbers of all elements
SOVA2 [1]
Fe(NO3)2=0
Fe+2(+3+3*-2)=0
Fe+2*-3=0
Fe=-(-6)
Fe=+6

So, Fe=+6, N=+3, O=-2
