The correct answer is false. <span>Chemical equations are balanced not by changing the subscripts of the molecules instead by changing the coefficients of each molecule. However, the subscripts are helpful in balancing equations because they are used in counting the number of atoms or molecules.</span>
Answer:
Alpha feto protein AFP
Explanation:
Plasma protein bio marker alpha feto protein is detected by the liver test to determine the presence of liver cancer in a patient.
High levels of alpha feto proteins is also a sign of cancer of ovaries and testicles and also liver non cancerous diseases that is cirrhosis and hepatitis.
The increased levels of two liver enzyme AST and ALT is also indicator of hepatic cancer.

Answer:
ΔH = - 44.0kJ
Explanation:
H2O(l)→H2O(g), ΔH =44.0kJ
In the reaction above, liquid water changes to gaseous water. This occurs through a process known as boiling. This process requires heat, hence the ΔH is positive.
If he reaction is reversed, we have;
H2O(g)→H2O(l)
In this reaction, gaseous water changes to liquid water. This process is known as condensation. The water vapor loses heat in this reaction. Hence ΔH would be negative but still have the same value.
Liquid oxygen can be used as an oxidizer in rocket fuel as one of two propellants needed.
