If an atom has an atomic number of 6 and and abdomens mass of 12 how many electrons does it have
Basile [38]
Atomic number refers to the proton number of the atom itself. Number of electrons in an atom (an atom that is not reacted with any other molecules / Just the atom alone), is the same as the number of protons, because each electron has 1 negative charge, and each proton 1 positive charge, where they cancel out on each other to become a neutral charge.

So, when atomic number is 6, proton number is also 6, and number of electrons will also be 6 in that atom.

Hope this helps! :)

Which is a true statement?
labwork [276]

Answer: B) Particles can be filtered from a suspension.

Explanation: Colloids are solutions with particle size intermediate between true solutions and suspensions. They exhibit tyndall effect that is scattering of light.

Suspensions have large sized particles which settle when left undisturbed for sometime and thus can be filtered off easily.

The particle size in colloids is less and hence they do not settle under the effect of gravity.

A solution can be homogeneous in which the composition is uniform or heterogeneous in which is the composition is not uniform.

Listed below are possible solutes. In your possession is a beaker with 500 milliliters of water. You want to make an aqueous sol
slavikrds [6]

Answer: I & III

Explanation:  Solutes are the substances which are minimum in quantity and which is required to dissolve in the solvent (which is larger in quantity) in order to make a solution.

In the asked question, it is given that the water is the solvent and from the given solutes we have to pick which would make an aqueous solution with the highest concentration of solute possible.

Thus the most appropriate answers could be the Ammonia and hexanol which can make the highest possible concentration of solute as ammonia is the gas which is highly soluble in water and hexanol is an alcohol which has an affinity for water. Thus the correct option is I & III

A battery has chemical energy, which can be used to generate thermal and radiant energy in a lightbulb. Which best explains what
WARRIOR [948]

Answer is: The total energy in the system remains the same as the decrease in chemical energy equals the increase in thermal and radiant energy.

The law of conservation of energy states that the total energy of an isolated system remains constant; energy can neither be created nor destroyed; it can only be transformed or transferred from one form (in this example chemical energy) to another (in this example thermal and radiant energy).

Radiant energy or light is the only kind of energy we can see with our eyes. Light have different wavelenght and different color.

Chemical energy - this type of energy is often found in things like batteries or food.

Strontium-90 is one of the products of the fission of uranium-235. This strontium isotope is radioactive, with a half-life of 28
Firlakuza [10]

Answer:

67.6 years is the time the isotope take to decay from 0.900g to 0.170g

Explanation:

The radioactive decay follows first order law:

Ln [A] = -kt + ln[A]₀

<em>Where [A] is concentration after time t,</em>

<em>k is decay constant:</em>

<em>k = ln 2 / t(1/2)</em>

<em>k = ln2 / 28.1 years</em>

<em>k = 0.02467 years⁻¹</em>

<em>[A]₀ = Initial concentration.</em>

<em />

We can replace concentration and use the mass of the isotope:

Ln [A] = -kt + ln[A]₀

Ln [0.170g] = -0.02467 years⁻¹t + ln[0.900g]

-1.667 = -0.02467 years⁻¹t

t =
