I need help with this molecular formula problem really quick!!

Answers

Answer: From top to bottom, 1 3 4 5 6

Explanation: The empirical formula is the most reduced whole number ratio of elements. N2O4 is the only compound that can be further reduced, making the empirical formula NO2, and thus is different from the molecular formula.

Plz help based on graph 1. what is happening to the population of the mice between days 0 and 7? suggest some possible reasons why this trend is occurring? 2. what is the approximate carrying capacity of this mouse population from observing the graph? how do you know this ? 3. the farmer who owns the barn has been given two barn cats how will this affect the size of the mouse population explain your answer 4. What are some other factors that will change the size of the mouse population in the future?

Answers

1.  The population of the mice seemed to grow until day 7.  This likely occurred do to the fact that the mice kept reproducing and they had enough resources to sustain the population growth.
2.  the carrying capacity is around 24 since that is when they reach population equilibrium.
3.  This will lower the mice population since it will introduce a predator that will lower the carrying capacity.
4.  The mice population can change in the future if more predators are introduced, if predators die out/go away, if an invasive species is introduced that competes with the mice for resources, if the climate changes, and if the amount of resources available to the mice increases or decreases.

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

Based on intermolecular forces, which of these substances would have the highest boiling point?(1) He (3) CH4
(2) O2 (4) NH3

Answers

NH3 would have the highest boiling point because the molecules have all 3 types of bonds:
London dispersion, because all molecules do
Hydrogen Bond, because of the fact that hydrogen is present and so is Nitrogen, one of the elements that hydrogen will form a hydrogen bond with.
Dipole Bond: Because the NH3 has a lone pair

Answer: NH3

Hope this helped!!!
Based on intermolecular forces, NH3 would have the highest boiling point.

Bases in solution produce what type of ions?a. sulfide ions
b. chloride ions
c. hydroxide ions
d. hydronium ions

Answers

Bases produce hydroxide ions, while acids produce hydrogen ions. 

Bases have a pH of above 7, and are bitter and slippery. 

Answer: c. hydroxide ions

Final answer:

Bases in a solution produce hydroxide ions (OH-). This ability to donate a hydroxide ion is what characteristically defines a substance as a base.

Explanation:

When bases dissolve in water, they produce hydroxide ions (OH-). In chemistry, bases are substances that can accept hydrogen ions (H+) or donate a hydroxide ion. For example, when sodium hydroxide (NaOH), a common base, dissolves in water, it dissociates into sodium ions (Na+) and hydroxide ions (OH-). This is the characteristic that defines a substance as a base.
