K1x1=k2x2=F
k2x2/k1=x1
F=keqx=keq(x1+x2)
sub.s in for x1:F=keq(k2x2/k1+x2)
sub.s in for F (in terms of k2 and x2)k2x2=keq(k2x2/k1+x2)
x2 is in every term:k2=keq(k2/k1+1)
multiply both sides by (k1/k2+k1)
keq=(k1/k1+k2)k2
keq=(1/k1+1/k2)−1
Formula is moles =massin grams of HNO3/molar mass of HNO3
Answer:
1.99 x 10²³ formula units
Explanation:
Given parameters:
Mass of AgF = 42.15g
Unknown:
The amount of formula units
Solution:
To solve this problem, we set out by find the number of moles in this compound from the given mass.
Number of moles =
molar mass of AgF = 107.9 + 19 = 126.9g/mol
Number of moles = = 0.33 moles
1 mole of a substance = 6.02 x 10²³ formula units
0.33 moles of AgF = 0.33 x 6.02 x 10²³ = 1.99 x 10²³ formula units
<h3>
Answer:</h3>
1170.43 m³
<h3>
Explanation:</h3>
<u>We are given;</u>
- Initial pressure, P1 as 808 kPa
- Initial temperature, T1 as 585 K
- Initial volume, V1 as 295 m³
- New pressure, P2 as 102 kPa
- New temperature, T2 as 293 K
We are required to find the new volume;
- We are going to use the combined gas law
- According to the gas law;
- Thus, rearranging the formula;
Therefore, the volume is 1170.43 m³
Answer:
Salinization is the increase of salt concentration in soil and is, in most cases, caused by dissolved salts in the water supply. This supply of water can be caused by flooding of the land by seawater, seepage of seawater or brackish groundwater through the soil from below.
