Answer:
A white dwarf is what stars like the Sun become after they have exhausted their nuclear fuel. Near the end of its nuclear burning stage, this type of star expels most of its outer material, creating a planetary nebula. Only the hot core of the star remains. ... That means a white dwarf is 200,000 times as dense.
Explanation:
they are cold
they are about the size of Earth
these both are not true
Answer is: t<span>he hot soup will lose heat and the ice water will gain heat.
</span><span>Heat spontaneously flows from a hotter to a colder body.
</span>The thermal radiation<span> is </span>electromagnetic radiation<span> generated by the </span>thermal motion<span> of </span>charged particles<span> in </span>matter (in this case from the hot soup to the cold water).
The answer to this question would be: 3.125%
Half-life is the time needed for a radioactive molecule to decay half of its mass. In this case, the strontium-89 is already gone past 5 half lives. Then, the percentage of the mass left after 5 half-lives should be:
100%*(1/2^5)= 100%/32=3..125%
5 electrons
Boron atomic number 5 has five electrons in its ground state.
Commonly Boron will lose 3 electrons leaving 2 electrons in its most common ionic form.
Explanation:
The atomic number gives the number of protons. Protons which have a positive charge are balanced by an equal number of electrons in a neutral atom.
Boron number 5 has five protons and therefore as a neutral atom also has five electrons.
Boron has an electron configuration of
1s22s22p1
The most stable electron configuration for Boron is
1s2
+ 3 charges. By losing three electrons Boron can achieve the stable electron structure of Helium

Hello there!
<span>A vegetable garden is 12 meters long by 7 meters wide. It is home 168 mice. What is the population of the mice.
</span>
The size of the vegetable garden is just extra information.
The only information we need is: "<span>It is home 168 mice"
This means the population of mice is 168. Meaning, there are 168 mice living there.
I hope I helped!
Let me know if you need anything else!
