You forgot one...and that happens to be the answer---> Accuracy
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:
C5H12 + 8O2 —> 5CO2 + 6H2O
The coefficients are 1, 8, 5,6
Explanation:
The equation for the reaction is given below:
C5H12 + O2 —> CO2 + H2O
Now let us balance the equation. This is illustrated below:
There are 5 atoms of C on the left side and 1atom on the right side. It can be balance by putting 5 in front of CO2 as illustrated below:
C5H12 + O2 —> 5CO2 + H2O
There are 12 atoms of H on the left side and 2atoms on the right. It can be balance by putting 6 in front of H2O as illustrated below:
C5H12 + O2 —> 5CO2 + 6H2O
There are a total of 16 atoms of O on the right side and 2atoms on the left side. It will be balance by putting 8 in front of O2 as illustrated below:
C5H12 + 8O2 —> 5CO2 + 6H2O
Now we see clearly that the equation is balanced as the number of atoms of the different elements on both sides of the equation are the same.
The coefficients are 1, 8, 5,6
