Answer:
B) 12.5L
Explanation:
-We apply the mixed Gas Law:
Where:
is the given pressure of the gas
is the volume of the gas
is the number of moles of the gas
is the ideal gas constant and temperature respectively.
#We make V the subject of the formula and substitute to solve for it;
Hence, the volume of the gas is 12.5 L
Answer:
The equilibrium concentration of chlorine gas, Cl₂(g), is 0.0625 M
Explanation:
Chemical equilibrium is established when there are two opposite reactions that take place simultaneously at the same speed, so that no changes are observed as time passes, despite the fact that the substances present continue to react with each other.
The mathematical expression that represents Chemical Equilibrium is known as the Law of Mass Action and is stated as: The ratio of the product of high concentrations to the stoichiometric coefficients in the reaction of products and reactants remains constant at equilibrium. For any reaction:
aA + bB ⇄ cC + dD
the equilibrium constant Kc is calculated as:
In this case, you have:
2 ICl(g) → Cl₂(g) + I₂(g)
So, the equilibrium constant Kc is:
Being:
- Kc= 0.10
- [Cl₂]= ?
- [ICl]= 0.50 M
- [I₂]= 0.40 M
Replacing:
Solving:
0.1= 1.6 * [Cl₂]
[Cl₂]= 0.1 ÷ 1.6
[Cl₂]= 0.0625 M
<u><em>The equilibrium concentration of chlorine gas, Cl₂(g), is 0.0625 M</em></u>
One mole contains 6.02×10²³
If x mole contains 3.131×10²⁴
x = 3.131×10²⁴
-------------
6.02×10²³
x = 0.52×10²⁴¯²³
x = 0.52×10¹
x = 5.2moles....

(1) • Balanced Equation : 2HgO (s) ---> 2 Hg (l) + O₂ (g)
• Line a is represented by activation energy, or the smallest amount of energy needed for molecules to undergo a chemical reaction.
• Activated complex is the intermediate state during the conversion of reactants into products. In this case it is represented by Hg----O-----O----Hg. The dashed lines indicate that the bond between Hg and O are breaking and their length is increasing and the dashed line between oxygen atoms indicate that the bond is decreasing and bond formation is taking place.
• This reaction is endothermic as the energy of reactants is smaller than the energy of products.
(2) • Balanced Equation : CH₃Br + OH⁻ ---> CH₃OH + Br⁻
• The hydroxide ion reacts with the bromomethane, resulting in a double replacement reaction. The 'CH₃' in 'CH₃Br' joins with the hydroxide ion to form CH₃OH, while the Br breaks off as an ion.
• Take a look at the energy diagram below.
It all depends on the objects' densities ,because if they're less dense than the oil they will not even sink to the bottom of the beaker
