Commercial fertilizers, which are made by humans, are used to enrich soil for healthier crops. However, erosion may carry the fertilizer chemicals to the oceans. The presence of these chemicals may cause certain kinds of algae to reproduce rapidly. This decreases the amount of oxygen in the water, which can cause organisms that depend on it, like fish, to die.Which statements describe the impact of the use of fertilizers? Select two options.
It improves the growth of crops.
It provides more food for fish.
It causes erosion and washes away soil.
It causes the death of crops.
It harms organisms that live in the oceans.
Answers
The statements that describe the impact of the use of fertilizers are as follows:
- It harms organisms that live in the oceans
- improves the growth of crops
What is the effect of eutrophication?
Eutrophication is the process that involves the addition of artificial or natural nutrients, mainly phosphates, through detergents, fertilizers, or sewage, to an aquatic system.
According to this question, commercial fertilizers, which are made by humans, are used to enrich soil for healthier crops. However, erosion may carry the fertilizer chemicals to the oceans which leads to eutrophication.
This eutrophication may cause certain kinds of algae to reproduce rapidly, hence, having the following impacts:
- It harms organisms that live in the oceans due to reduced oxygen content.
- improves the growth of crops due to excessive nutrients

Answers
Density = 1.504 g/mL⁻¹
Molar mass HNO₃ =63.01 g/mol
M = 1000 * T* D / mm
M = 1000 * 0.68 * 1.504 / 63.01
M = 1022.72 / 63.01
M = 16.23 mol/L

What are the 3 types of rocks existing on earth?
The outermost of them, called the crust, is composed of three types of rocks: magmatic, sedimentary and metamorphic. They are defined through the origin of several minerals and can be characterized with chemical composition, texture or shape, but the most used specification is based on composition.
The property does Valerie use for classification purposes is formation.

4792.3/100 = 47.923 this is the average atomic mass of Titanium
Final answer:
The average atomic mass of titanium, calculated by weighting each isotope's mass by its percent abundance, is approximately 47.923 atomic mass units (amu). This aligns closely with the atomic mass on the periodic table of 47.867 amu.
Explanation:
The average atomic mass of titanium can be calculated by weighting each isotope's mass by its percent abundance, which is essentially what an 'average' is. Here is how each isotope of titanium contributes to the average atomic mass:
- 46Ti: 46 amu * 0.08 = 3.68 amu
- 47Ti: 47 amu * 0.078 = 3.666 amu
- 48Ti: 48 amu * 0.734 = 35.232 amu
- 49Ti: 49 amu * 0.055 = 2.695 amu
- 50Ti: 50 amu * 0.053 = 2.65 amu
Adding it all up: 3.68 amu + 3.666 amu + 35.232 amu + 2.695 amu + 2.65 amu = 47.923 amu. Therefore, the calculated average atomic mass of titanium is approximately 47.923 amu, which aligns closely with the atomic mass on the periodic table of 47.867 amu.

has higher boiling point than
, as there has been stronger hydrogen bonding in
. Thus, option 2 is correct.
The boiling point has been the temperature at which the liquid has been converted to the gaseous form. The boiling point has been based on the intemolecular attractions between the atoms.
Higher boiling point
Based on the intermolecular interactions, the compound with higher intermolecular force required more energy to break the bond and change the state, and thus have high boiling point.
The hydrogen sulfide and water has hydrogen bonding. The hydrogen bonding has been based on the electronegativity of the atom involved. The more electronegative atom, stronger will be hydrogen bonding and thereby higher boiling point.
In and
, the oxygen has been more electronegative than sulfur and thus results in stronger hydrogen bonding.
Thus, has higher boiling point than
