Answer:
See detailed explanation.
Explanation:
Hello!
In this case, for the reaction:
It is known that the equilibrium constant tends to be greater than 1; therefore, it is a reaction that tends to go rightwards towards the formation of hydrogen iodide.
a) Here, since the reaction tends to form the product, it is clear that the initial concentration of iodine and hydrogen will decrease as the reaction reaches equilibrium in order to increase the concentration of hydrogen iodide.
b) Yes, it stops at the point in which the following expression:
Equals the equilibrium constant.
Best regards!
Answer:
Acid :
Conjugate base :
Base:
Explanation:
According to the Lewis concept :
- An acid is defined as a substance that accepts electron pairs .
- Base is defined as a substance which donates electron pairs.
According to the Bronsted-Lowry conjugate acid-base theory:
- An acid is defined as a substance which looses donates protons and thus forming conjugate base .
- A base is defined as a substance which accepts protons and thus forming conjugate acid.
Given reaction :
is acting as an acid because it is accepting hydroxide ion.And after accepting hydroxide ion it forms its conjugate base that is
Since, is acting as an acid will obviously act as base.
Answer:
Use E = h*c / lambda, where h is Planck's constant, c is the speed of light, and lambda is the wavelength.
E = (6.626 * 10^-34 J*s x 3.00 * 10^8 m/s) / (1*10^-6 m) = 1.99 * 10^-19 J

Hello!
We have the following data:
Area (
A) = 50 square feet
Mass (
m) = 8.5 ounces
Density (
d) = 2.70 g/cm³
Volume (
V) = ?
Thickness (
T) =? (in mm)
To move on, we must transform the area of 50 ft² in cm², let's see:
1 ft² ------- 929,0304 cm²
50 ft² -----
AIn the same way, we will convert the mass of 8.5 oz in grams, see:
1 oz -------- 28,3495 g
8,5 oz -------
mKnowing that the density is 2.70 g/cm³ and the mass is 240.97075 g, we will find the volume, applying the data in the density formula we have:
The statement wants to find the thickness of the packaging, for this we have some important data, such as: V (volume) = 89,25 cm³ and Area (A) = 46451,52 cm² and T (thickness) =? (in mm)
In the calculations of Costs in Surface Treatment of a part within the flat geometry, we will use the following formula:
We will convert to millimeters, going through a decimal place on the right
Hope this helps! :))
