Organic fertilizers are made from mined rock minerals, and natural plant and animal materials. They include ingredients like manure, guano, dried and powdered blood, ground bone, crushed shells, finely pulverized fish, phosphate rock, and wood.
Inorganic fertilizer is synthetic, comprised of minerals and synthetic chemicals. Most of the minerals in inorganic fertilizer are mined from the earth, and balanced inorganic fertilizers are high in all three macronutrients and can contain ammonium sulfate, magnesium sulfate, and potassium chloride.

The sign of AG is negative a low or high temperature?
Explanation:
AH is negative because the reaction gives out heat (exothermic).
AS is negative because the total entropy of the reactants is greater than that of the products (there are 4 moles of gas on reactant side compared to only 1 mole on the product side). Thus, the reactants are said to be "messier" than the products.
AG is negative at lower temperatures because at low temperatures, -TAS is more negative, resulting in the negative sign of AG.

C. The final substance in beaker A is a pure substance while in Beaker B is a mixture
Explanation:
A pure substance is a substance that contains a constant and definite proportion of a single substance. Elements and compounds are the two known pure substances while mixtures are substances of different compositions mixed together.
In this question, two beakers; A and B are said to contain different substances. Beaker A contains elemental sulfur (S) that forms a yellow powder while beaker B contains sand and water. From the explanation above, the final substance in beaker A is a pure substance (element) while in beaker B is a mixture of sand and water.

what form of the ideal gas law would you use to calculate the volume of gas
Answer:
V = nRT/P
Explanation:
The ideal gas law states that
PV=nRT
where P = pressure, V = volume, n = number of moles, R = ideal gas constant, and T= temperature
P V = n R T
to get V on its own, divide both sides of the equation by P
V = (nRT)/P

I para realizar un receta casera de bizcocho se necesitan 100 gramos de azúcar, calcula los moles a los que equivale y el número de moléculas de sacarosa.
The complete question is as follows: I want to make a homemade cake recipe you need 100 grams of sugar, calculate the moles to which it is equivalent and the number of molecules of sucrose.
Answer: In 100 grams of sugar there are 0.292 moles and the number of molecules of sucrose are [tex]1.76 \times 10^{23}[/tex].
Explanation:
Given: Mass = 100 g
Molar mass of sugar = 342.3 g/mol
As number of moles is the mass of substance divided by its molar mass.
Hence, moles of sucrose are calculated as follows.
[tex]Moles = \frac{mass}{molar mass}\\= \frac{100 g}{342.3 g/mol}\\= 0.292 mol[/tex]
According to mole concept, 1 mole of every substance contains [tex]6.022 \times 10^{23}[/tex] molecules.
Hence, the number of molecules present in 0.292 mol are calculated as follows.
[tex]0.292 mol \times 6.022 \times 10^{23}\\= 1.76 \times 10^{23}[/tex]
Thus, we can conclude that in 100 grams of sugar there are 0.292 moles and the number of molecules of sucrose are [tex]1.76 \times 10^{23}[/tex].

distilling ethanol from a wine to determine the percentage of alcohol in a wine uses what type of property
physical property
bonding property
homeowner's property
Answer:
Bonding property
Explanation:
Distillation deals with boiling solutions. Therefore the boiling point has a major part to play. Boiling point of a substance deals with the type of bonds present. For example water has hydrogen bonding which is a weak intermolecular force therefore the boiling point of water isn't that high. If we were to focus on an ionic compounds the boiling point would be higher because ionic compounds have ionic bonding which are stronger bonds which therefore requires more energy to break those bonds therefore a higher boiling point.
In this case for the ethanol to distill the property it's focusses on is the bonds. The strength of the bonds really.

What is the molarity of a solution of 58.7 grams of MgCl2 in 359 ml of solution?
Answer:
1.72 M
Explanation:
Molarity is the molar concentration of a solution. It can be calculated using the formula a follows:
Molarity = number of moles (n? ÷ volume (V)
According to the information provided in this question, the solution has 58.7 grams of MgCl2 in 359 ml of solution.
Using mole = mass/molar mass
Molar mass of MgCl2 = 24 + 35.5(2)
= 24 + 71
= 95g/mol
mole = 58.7g ÷ 95g/mol
mole = 0.618mol
Volume of solution = 359ml = 359/1000 = 0.359L
Molarity = 0.618mol ÷ 0.359L
Molarity = 1.72 M

A 6.00 g sample of an optically pure compound was dissolved in 40.0 mL of CCl4. The observed rotation was +3.30 °, measured in a 10.0 cm (1.00 dm) polarimeter tube.
The question is incomplete, the complete question is:
If a 6.00 g sample of an optically pure compound was dissolved in 40.0 mL of [tex]CCl_4[/tex] and the observed rotation was +3.30°, measured in a 10.0 cm (1.00 dm) polarimeter tube, how would one determine the specific rotation of the pure compound?
Answer: The specific rotation of the pure compound is [tex]+22^o[/tex]
Explanation:
To calculate the specific rotation of a pure compound, we use the equation:
[tex][\alpha]=\frac{\alpha_{\text{observed}}}{C\times l\text{( in dm)}}[/tex]
where,
[tex][\alpha][/tex] = specific rotation of a pure compound
[tex]\alpha_{\text{observed}}[/tex] = observed rotation of the compound = [ex]+3.30^o[/tex]
C = concentration in g/mL = 6.00 g/40 mL = 0.15 g/mL
l = path length = 1.00 dm
Putting values in above equation, we get:
[tex][\alpha]=\frac{+3.30^o}{0.15\times 1.0}[/tex]
[tex][\alpha]=+22^o[/tex]
Hence, the specific rotation of the pure compound is [tex]+22^o[/tex]

which ancient African Kingdom is located in western Africa?
Answer:
Ghana Empire is was a kingdom in western Africa.
The Oyo Empire was the ancient African Kingdom is located in western Africa.
What is Oyo Empire?The Oyo Empire prospered on regional trade and became a key facilitator in moving slaves from Africa's interior to the coast and waiting European sailing ships, with its capital at Old Oyo near the River.
The human trade was so extensive that this region of Africa became known simply as the "Slave Coast."
Finally, despite all efforts, the Oyo Empire became a protectorate of the United Kingdom in 1888; its states ceased to exist as a superpower, and it never regained its prominence in the region.
During the colonial period, however, the Yoruba were one of Africa's most urbanized groups.
Thus, the ancient African kingdom of the Oyo Empire was located in western Africa.

What is the two major types of chemical bonding?
Answer:
Ionic bond and covalent bond
Explanation:
The two main types of chemical bonding are ionic bond and covalent bond.
In an ionic bond, there is a transfer of electrons from one atom to another. Usually from a metal to a nonmetal leading to the existence of an ion pair. Ionic compounds are soluble in water and have high melting and boiling points due to the strong electrostatic interaction between ions in the compound.
A covalent bond involves sharing of electrons between atoms. In an ordinary covalent bond, the shared electrons are furnished by the two bonding atoms while in a dative covalent bond, the two bonding electrons are furnished by only one of the bonding species.
