<span>the balanced equation for the reaction is as follows
2C</span>₄H₁₀ + 13O₂ ---> 8 CO₂ + 10H₂<span>O
stoichiometry of C</span>₄H₁₀ to O₂ <span>is 2:13
stoichiometry applies to the molar ratio of reactants and products. Avagadros law states that volume of gas is directly proportional to number of moles of gas when pressure and temperature are constant.
Therefore volume ratio of reactants is equal to molar ratio, volume ratio of C</span>₄H₁₀ to O₂<span> is 2:13
2 L of </span>C₄H₁₀ reacts with 13 L of O₂<span>
then 100 L of </span>C₄H₁₀<span> reacts with 13/2 x 100 = 650 L
therefore 650 L of O</span>₂<span> are required </span>
The correct answer is 0.72 g/cm3
Explanation:
The density of a material depends on both its mass (amount of matter), which is usually provided in grams (g), and its volume (space occupied), which is provided in units such as cubic centimeters cm3. Moreover, to find how dense the material is, take the mass and divide it into the volume. The process for finding the density of the block of wood is shown below:
![d = \frac{m}{v}](https://tex.z-dn.net/?f=d%20%3D%20%5Cfrac%7Bm%7D%7Bv%7D)
![d = \frac{46 g}{64 cm3}](https://tex.z-dn.net/?f=d%20%3D%20%5Cfrac%7B46%20g%7D%7B64%20cm3%7D)
![d = 0.718 g/cm3](https://tex.z-dn.net/?f=d%20%3D%200.718%20g%2Fcm3)
This means the density is 0.71g/cm3 and this can be rounded to 0.72 g/cm3
Answer:
C.) More NO₂ and SO₂ would form
Explanation:
Equilibrium:
This is the state of reaction in which the rate of forward reaction and reverse reaction are same.
There are three factors that effect the equilibrium condition.
The change in concentration
The change in volume
The change in temperature
In given equilibrium reaction,
SO₂ + NO₂ ⇄ NO + SO₃ + heat
when SO₃ is added it means more amount of product is on right side and equilibrium is disturb. Thus equilibrium is shifted toward the left produced more SO₂ and NO₂ and regain the equilibrium.
The statement that is true about the formation of Earth's oceans is that the atmosphere formed before the oceans.
