Explanation:
To balance equations try to list out each element on both sides and start with the ones that aren't equal
Answer:(1)The urinary system's function is to filter blood and create urine as a waste by-product.
(2) two kidneys we have.
(3)The kidneys act as very efficient filters for ridding the body of waste and toxic substances, and returning vitamins, amino acids, glucose, hormones and other vital substances.
(4)Two ureters.
These narrow tubes carry urine from the kidneys to the bladder. Muscles in the ureter walls continually tighten and relax forcing urine downward, away from the kidneys.
(5)A hollow, muscular, balloon-shaped organ that expands as it fills with urine.
(6)The urethra is the vessel responsible for transporting urine from the bladder to an external opening in the perineum.
(7)Urine is formed in the kidneys through a filtration of blood. The urine is then passed through the ureters to the bladder, where it is stored. During urination, the urine is passed from the bladder through the urethra to the outside of the body.

Answer:
It is observed that H2 gas gives out 286kJ/m, Methane gives out 802.3kJ/m and hexane gives out 4163kJ/m of heat. They are all exergonic or exothermic reaction but have different values of heat given out. The amount of carbon atom present, is what determines the heat given out, as higher carbon compound like Hexane gave out more heat than Methane and Hydrogen gas have out the least.
Explanation:
Answer : If an increase in temperature accompanies a reaction, energy is released. Explanation :In thermodynamics, the reaction is considered as a system and the medium in which the reaction occurs which is usually an aqueous medium is considered as its surrounding. When the heat flows from the system to its surrounding, it increases the temperature of surrounding medium because the heat released by the system is absorbed by its surrounding. This is known as exothermic reaction. An exothermic reaction is always accompanied by energy release. On the other hand, when the heat flows from the surrounding towards system, it decreases the temperature of the surrounding medium. This is known as endothermic reaction. From the above discussion we can say that If an increase in temperature accompanies a reaction, energy is released.
Good luck ;)
