A statement that describes what scientists expect to happen every time under a given set of conditions is call a scientific

Anss\zyew:yes,the answer is very normal and well done

Answer:

No, there is no evidence or proof that proves the scientific theory. Therefore, the statement is not a scientific theory.

Explanation:

The goats can stretch their necks up to 7 feet, biting branches and low lying leaves. They eat poison oak and can clear rocky cliffs -- something other livestock can't do. And it's easier to control where the goats cut a fire break, unlike controlled burns -- another method of removing wildfire fuel.

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

Density is the measure of a mass per unit volume of a material substance

density= Mass/volume

The unit of density is g/cm^3

Answer:

23.7

Explanation:

The formula to convert from L to dL is:

dL = L x 10

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"

answer

When an electron temporarily occupies an energy state greater than its ground state, it is in an excited state. An electron can become excited if it is given extra energy, such as if it absorbs a photon, or packet of light, or collides with a nearby atom or particle

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.

Answer:

The ability to do work is called energy.

Answer:

A

Explanation:

B: not B. Opinions don't matter. Facts do.

C: its a consideration. It will limit the scope of the experiment. But it's not relevant to the investigation. Not C

D: You might want to contact some scientists to see what they think about your investigation, but randomly interviewing anyone and everyone is not the answer.

You want to do A for certain.

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)
