Answer:

Facts: A D and maybe C I think you are intended to say C

Explanation:

A is certainly not an opinion. It is either true, or it is not. I think it is intended as a fact.

B is an opinion (which I think is true)

C is kind of iffy. It might be true and it might be an opinion. In looking it up, it is factually incorrect. Cats are related to wildcats in the middle east.

D is also iffy. They can just eat disease free rodents. I'd classify it as more opinion than fact.

E. definitely an opinion.

An excess of a divalent metal M was dissolved in a limited volume of hydrocloric acid. If 576cm³ of hydrogen was librated at s.t.p , what was the mass of metal that produced this volume of gydrogen?( M = 24, H = 1 , molar volume of gas at s.t.p = 22.4dm³)​

Answers

Answer:

14.8 g

Explanation:

step 1 You first have to convert the cm^3 to dm^3 by dividing the volume by 1000 then find the number of mols for Hydrogen gas

from there you can use the of moles for hydrogen to find the moles of the metal step 2

then step 3 you multiply the number of by The Mr or Fr giving you your mass

what is the concentration of hydrogen ion, H+, present in a water sample if 100. ml of the sample requires 7.2 ml of 2.5 x 10 -3 M NaOH to be neutralized

Answers

Answer:  1.8x10^-4 M H+

Explanation:  The number of moles of NaOH added to the 100 ml soultion will be equal to the number of moles of H+ present in that solution.  

Moles NaOH in 7.2 ml of 2.5x10^-3 M NaOH

(2.5x10^-3 M NaOH) is the same as 2.5x10^-3 moles NaOH/liter

(2.5x10^-3 moles NaOH/liter)*(7.2 ml)*(1 liter/1000ml) = 1.8x10^-4 moles NaOH used to titrate 100 ml of the acid.  That means there was 1.8x10^-4 moles of H^+ in 100 ml.  

Concentration of H^+ = (1.8x10^-4 moles H)/0.100 l) = 1.8x10^-4 M H+

(pH of 3.74)

he difference between a stable isotope and an unstable isotope of an element is that __________. ANSWER the unstable isotope decays and is always transformed into a stable form of the same element the stable isotope has a nucleus that decays spontaneously and is radioactive the unstable isotope has a nucleus that does not decay spontaneously and is never radioactive the stable isotope has a nucleus that decays spontaneously but is not radioactive the unstable isotope has a nucleus that decays spontaneously, is radioactive, and can be transformed into an atom of another elemen

Answers

We know that any known element is defined by the number of protons in its nucleus (which is the same as the number of orbiting electrons).

We can define isotopes as the atoms of the same element but that have a different number of neutrons in the nucleus. The correct statement of the difference between stable isotopes and unstable isotopes is:

"The difference between a stable isotope and an unstable isotope of an element is that the unstable isotope has a nucleus that decays spontaneously, is radioactive, and can be transformed into an atom of another element"

Particularly we can define two of these, the stable isotopes, that can remain as they are for a lot of time, and the unstable isotopes, that have more neutrons in its nucleus than a stable isotope, and because having those extra neutrons in the nucleus needs energy, eventually the isotope will experience a spontaneous radioactive decay, which "breaks" the nucleus in different ways, and, in some cases, generates different elements in the process.

Then we can conclude that:

"The difference between a stable isotope and an unstable isotope of an element is that the unstable isotope has a nucleus that decays spontaneously, is radioactive, and can be transformed into an atom of another element"

Is it possible to prove that something is real or true of you can’t directly observe it? If no, why not? If yes, how would you do that?

Answers

Answer:

I don't know if you can directly prove it with evidence if you haven't observed it but you can maybe take an educated guess by the aftermath of it?

For example, you see a burnt log. At this time, people don't know what fire is. After we study the log, we could see that it takes extreme temperature in order to burn the log and that would help people see that there is a force like fire that can cause this. In a way, finding out that extreme temperatures burns stuff is another step closer to the discovery and proof of fire
