Answer:
Enthalpy is the amount of heat released or absorb. The total enthalpy can be found by subtracting the products' enthalpy by the reactants' enthalpy
The answer is 2.2 g.
First, we need to calculate a molar mass (M) of AgNO₃<span>. The molar mass is a mass of 1 mole of a substance. It is the sum of relative atomic masses (Ar), which are masses of atoms of the elements.
Relative atomic mass of Ag: Ar(Ag) = 108 g
Relative atomic mass of N: Ar(N) = 14 g
Relative atomic mass of O: Ar(O) = 16 g
So, the molar mass of </span>AgNO₃ is:
M(AgNO₃) = Ar(Ag) + Ar(N) + 3Ar(O) = 108 + 14 + 3*16 = 170 g
Now, we can make a proportion:
If 108 g of Ag is in 170 g of AgNO₃, how many silver will be in 3.4 g of AgNO₃:
108 : 170 = x : 3.4
After crossing the products:
x = 108 × 3.4 ÷ 170 = 2.16 g ≈ 2.2 g
Answer:
Organic fertilizers are those fertilizers that are not artificially produced but are natural and has carbon in them.
Fertilizers in the broad term are used to provide nutrient to the soil and boost growth of crops.
Some of the advantages of organic fertilizers to inorganic fertilizers are:
They do not make crusts on the soil, unlike inorganic fertilizers.
They help add structure to the soil because of the good water movement into the soil
They are easier on the soil because they feed good microbes.
a person not moving at all (if right put brainiest) plz
