Inorganic compounds contain carbon. Inorganic compounds usually lack carbon. Inorganic compounds are not associated with or made from living things
Answer:
when water hot, sugar melt go to the bottom. when water cold sugar freeze separates from water because of different freezing temperatures.
Explanation:
when things are hot they melt and when things get cold they freeze, think of regular water how it freezes and then melts.
15 X 10 ^23 atoms of O2 .. i guess
<span>Balanced nuclear reaction: 234/91 Pa → 4/2 He + 230/89 Ac.
1) number of protons and neutrons on both side of nuclear reaction must be the same. There are 91 protons (atomic number) and 143 neutrons (mass number - atomic number, 234 - 91 = 143 or (4-2) + (230 - 89) = 143)) on both side of reaction.
2) a</span>lpha
decay is radioactive decay<span> in which
an atomic nucleus emits
an alpha particle (helium
nucleus) and transforms into an atom with an atomic
number that is reduced by two and mass number that is reduced by four, so atomic mass of new element is 89 (91 - 2) and mass number is 230 (234 - 4 = 230).
3) look at atomic number, element with atomic number 89 is actinium.</span>
Answer:-
b. helium to carbon and oxygen
Explanation:-
After the red giant phase, stars like the sun follow a different evolutionary path than more massive stars. An alternative fusion process to the proton-proton chain now occurs.
The star will convert all of its core helium into carbon and oxygen, and then fusion will end
