Answer:
Toxicity is how much something can harm you, like poison. A quick example of this is rat poison. You can put it in traps to kill rats, but if you ingest it it'll also kill you. Also, tide pods are perhaps a more relevant example.

What are some limitations of a chemical formula ?
How are elements arranged on the Periodic Table of Elements ?
Why are some elements very reactive while others are unreactive ? ( Please provide a Evidence-based Explanation if you can )
Answer:
1 Answer. Following are the limitations of a chemical equation: (i) A chemical equation does not tell us the physical state of the reactants and the products in the reaction. (ii) It does not tell us the actual concentration or dilution of the reactants used in the reaction.

In an electrical wire, if instead of copper, plastic wire is used. Would it conduct electricity?Justify your answer.
Answer:
No, a plastic wire would not conduct electricity. This is because plastic is an insulator that does not allow electric current to flow through it. In a wire, electrical conductivity is provided by the movement of charged particles - typically, electrons. Copper is an excellent conductor of electricity because it has a high number of free electrons that are not bound to atoms and can move through the wire very easily. However, in a plastic wire, the tightly bound electrons of its atoms do not allow for the free flow of charges, thus preventing the passage of electric current.

Explanation:
Methane is a gas at room temperature and pressure. Explain why this is the case.
Answer:
hope it helps ❤
Explanation:
Methane only has london dispersion forces since it is nonpolar. London dispersion force is the weakest intermolecular force, so the forces between its molecules will be weak. This leads to a low boiling point that is lower than room temperature, which makes it a gas at room temperature.
if the hydroxide-ion concentration of an aqueous solution 1.0 x 10^-3 M, what is the [H+] in the solution? is the solution acidic, basic, or neutral?
Answer:
The pH of a solution with a hydroxyl ion (OH-) concentration of 10−10 M is 4. This is because the pOH of such a solution is 10 since that is the negative logarithm of its OH- ion concentration.

Why do elements within a period of the periodic table have different
properties?
A. They have different arrangements of core electrons.
B. They have different numbers of valence electrons.
C. Some are metals and some are nonmetals.
D. They have different combinations of protons and neutrons.
Answer:
It’s b
Explanation:
(Apex)
They have different numbers of valence electrons. Hence, option B is correct.
What are elements?Elements are the simplest substances which cannot be broken down using chemical methods.
Elements within the same period have different numbers of electrons in their valence shells from left to right and different electron configurations. Thus, all elements in the same period are chemically different from each other.
Hence, option B is correct.

what happens to the luminosity of a star as it moves through its main sequence stage from left to right.
Answer:
The luminosity of a star remains approximately constant during its time on the main sequence. There is a slight increase over time, which is, as you guessed, related to the changing composition of the star due to fusion.
When a star's luminosity and temperature begin to change, the point that represents the star on the H–R diagram moves away from the zero-age main sequence. ... If the rate of fusion goes up, the rate at which energy is being generated also increases, and the luminosity of the star gradually rises.
Hope this helps! have a nice day!

Help PLEASE!! Will mark brainly Calculate the total energy in 1.5 x 10^13 photons of gamma radiation having wavelength = 3.0 x 10^-12 m. Need to show ALL work.
Answer:
The total energy but the photons will give is 6.615 x 10^-14
Explanation:
Formula that can be used in this question is E= hf or E= hc/ λ
This is the formula that can be used to calculate the energy that the photon is carrying where it is given as the Planck's Constant .
Now putting the values given in the equation that can calculate energy we get Planck's Constant is equal to 6.62 x 10^-34
E=(6.62 x 10^-34 x 2.998 x 10^8) / ( 3 x 10^-12 )
E=6.615 x 10^-14
Answer:
The total energy but the photons will give is 6.615 x 10^-14
