One problem with using pesticides to control insects on crops is that the insects can develop resistance to the chemicals. How is this similar to the overuse of antibiotics?

Answers

Answer:

Explanation:

Overuse of antibiotics leads to bacteria's resistance against our drugs. This is increasing at an alarming rate and the reason is that overuse of antibiotics kills bacteria that lack the "resistance" gene or gene that can help them survive the antibiotics (similar is the case for insects that die to insecticides). But, some bacteria can have random mutations in their gene that can help them survive the antibiotic (similar is the case for some insects that can survive the insecticide), thus the surviving bacteria give rise to next generation of bacteria that are resistant to the given antibiotic (similar to how insects that survive the insecticide give birth to new insects that are resistant to insecticide too). Soon, every generation adds new antibiotic resistant bacteria (or new insecticide resistant insects in the case of insects) which is dangerous for all of life on this planet. Therefore, both are similar in the sense that new generations of these organisms will be resistant to our weapons against them.

Why is H2SO4 regarded as an ampholyte

Answers

I think sulfuric acid cannot be regarded as an ampholyte. Ampholytes are amphoteric molecules or that contains both acidic and basic groups. An amphoteric compound can react both as an acid and a base which sulfuric acid is not capable.

Enter the symbol of a sodium ion, Na+, followed by the formula of a sulfate ion, SO42−. Separate the ions with a comma only—spaces are not allowed.

Answers

Answer: Na⁺, SO₄ ²⁻.


Justification:


This is just a part of a bigger question.


But the instructions are complete to construct the ions.


The first ion requested is the sodium ion.


The symbol of sodium is Na.


When an electron is removed from the neutral atom, the atom wil result with an excess of protons, which translates onto an excess of positive charge.


Then, to show the new particle you must add a positve sign (+) in the form of superscript.


That is why you write Na⁺. By the way, a positive ion is named cation.


Regarding sulfate ion, it comes from the sulfuric acid, when you remove the two hydrogen atoms, each with a positive charge, then the sulfate ion will stand with a negative charge of 2.


The charge is told to belong to the entire ion, not a particular atom, soy you wirte it with the 2- symbol as a superscript for the entire species:


SO₄ ²⁻. A negative ions is called anion.


The answer, then, is: Na⁺, SO₄ ²⁻.

Writing the ion: Na⁺,SO₄²⁻

Further explanation

Ionic compounds consisting of cations (ions +) and anions (ions -)

The naming is preceded by the cation then the anion with the -ide suffix added

Generally for this ion compound consists of metal elements as cations and non-metals as anions

Metal: cation, positively charged.

Nonmetal: negative anion.

The anion cation's charge is crossed

Example:

Fe₂S₃

Fe charge = 3+

S charge = 2-

The writing of the ionic charge is placed as a superscript behind the molecule/ atom, and the number is written before the positive or negative sign. For a single charge, there is no need to write the number

Example

Cl⁻ (single charge)

Mg²⁺ not Mg⁺²

For the element Na symbol which is group 1A and releases one electron, the symbol writing would be: Na⁺(single charge)

For polyatomic ions, the superscript charge is written after the subscript on the polyatomic element, so it becomes SO₄²⁻

These two ions when combined and bind to Na₂SO₄ (The anion cation's charge is crossed)

if written separately as Na⁺, SO₄²⁻
