Answer:
3.5 Kilometers
Explanation:
If he goes 7k an hour, then 30 minutes is half of that.
Hope this helps! :)
Answer:
no it dosen't matter
Explanation:
because it absorbed the light so it had to damage it.
The amount of matter in an object is said to be its mass. The SI base unit of mass is kilograms i.e. .
The mass of the object = (given)
For converting lbs to kg:
So,
Hence, the mass of object in kilograms is .
To compare the results when the independent variable is not involved
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>
