Answer:
Los ácidos húmicos son restos de vida orgánica totalmente descompuestos. Son moléculas de cadena larga que son de alto peso y de color marrón oscuro. No son un solo ácido. Más bien, "ácido húmico" es un término amplio que se refiere a una mezcla compleja de muchos ácidos diferentes que son solubles en soluciones alcalinas. Existen de forma natural como parte del ciclo de vida de la naturaleza en suelos, océanos y arroyos. Cómo se forman?
Cuando las plantas y los animales mueren, sus moléculas quedan disponibles en el suelo para ser utilizadas por otros organismos. Bacterias, hongos, protozoos, lombrices de tierra e incluso insectos consumen el material fresco. Después de largos períodos de tiempo, cuando la materia en descomposición se ha comido y transformado a través de varios ciclos, lo que queda es un material resistente que resiste una mayor descomposición, llamado humus. (Este proceso se conoce como "humificación"). El humus es un término general que se refiere a compuestos estables y altamente complejos que son resistentes a una mayor descomposición. Y el humus consta de tres componentes: ácidos húmicos, ácidos fúlvicos y humus. Los ácidos húmicos y fúlvicos han demostrado ser invaluables para entornos de suelo saludables, particularmente por sus contribuciones a la estructura del suelo y la transferencia de nutrientes entre el suelo y las plantas.
Answer:
4.283M
Explanation:
Hi!
We are given a certain amount of CoCl2, and we are asked to make a smaller portion of it but with a stronger concentration. Dilution is a process where we use this equation: to find the unknown variable.
Think of it this way:
You put a powdered water flavor enhancer into your bottle. You put 5 drops of it, but it evenly distributes around the bottle so it tastes fine.
Now, you put it in a very small, miniscule cup. You have only a certain amount of water and 5 drops of water, but the flavor is so strong since there is less of the water. This is known as the concentration. Volume is just the water+flavor booster.
Let's convert everything to liters since the volume should be in units of liters.
250mL=0.250L
0.150mL=0.150L
Now, let's plug it in. The first two numbers go in the left side of the equation, and we do not know the concentration of the second so we will substitute a variable.
0.250(2.570)=x(0.150) <em>Isolate X.</em>
4.283=x
x=molarity of the solution
The second question asks how many mL of the first solution would you need....since the relationship of MV should be consistent, it should be all of the solution needed.
Hello!
We know that by the Law of Avogrado, for each mole of substance we have 6.02*10²³ atoms, if:
The molar mass of of magnesium = 24.30 g/mol
If:
1 mol we have 6.02*10²³ atoms
1 mole of Mg we have 24.30 g
Then we have:
24.30 g ------------- 6.02*10²³ atoms
x ----------------------- 7.43*10²² atoms
I Hope this helps, greetings ... DexteR! =)
Explanation:
Reaction equation for the given chemical reaction is as follows.
Equation for reaction quotient is as follows.
Q =
=
= 0.256
As, Q > K (= 0.12)
The effect on the partial pressure of as equilibrium is achieved by using Q, is as follows.
- This means that there are too much products.
- Equilibrium will shift to the left towards reactants.
- More is formed.
- Partial pressure of increases.
The temperature change is calculated using the combined gas law
that is P1V1/T1 =P2V2/T2
P1= 100KPa
P2=90kpa
v1= 2.50 L
v2= 3.75 L
T1= 303 K
T2=?
T2 is therefore = P2V2T1/P1V1
=( 90 x 3.75 x303)/ (100 x2.50) = 409.05 K
