How much heat is absorbed in the complete reaction of 3.00 grams of SiO2 with excess carbon in the reaction SiO2(g) + 3C(s) → Si
defon

Answer:

31.24 kJ

Explanation:

  • SiO₂(g) + 3C(s) → SiC(s) + 2CO(g)        ΔH° = 624.7 kJ/mol

First we <u>convert 3.00 grams of SiO₂ to moles</u>, using its <em>molar mass</em>:

  • 3.00 g SiO₂ ÷ 60.08 g/mol = 0.05 mol

Now we <u>calculate the heat absorbed</u>, using the <em>given ΔH°</em>:

If the complete reaction of 1 mol of SiO₂ absorbs 624.7 kJ, then with 0.05 mol:

  • 0.05 mol * 624.7 kJ/mol = 31.24 kJ of heat would be absorbed.

What is a the volume of a salt crystal measuring 3.22 x 10^-2 cm by 1.5 x 10^-4 cm by 4.30 x 10^-3 cm?
aleksandr82 [10.1K]
Dimension of the salt crystal is:

Length = 3.22 x 10^-2 cm

Breadth = 1.5 x 10^-4 cm

Height = 4.30 x 10^-3 cm

So it is cuboidal in shape.

Volume = L × B × H

V = 3.22 \times  {10}^{ - 2}  \times 1.5 \times  {10}^{ - 4}  \times 4.30 \times  {10}^{ - 3}  \\  \\ V = 3.22 \times 1.5 \times 4.30 \times  {10}^{ (- 2 - 3 - 4)}  \\  \\ V = 20.769\times  {10}^{ - 9} \\  \\ V = 2.0769 \times  {10}^{ - 8} \\  \\ V  \approx 2.1 \times  {10}^{ - 8} \:  {cm}^{3}  \\  \\  \boxed{ \red{ \bold{answer: a}}}
