Answer: NH3 and H2O

Explanation:

NH4OH(l) --> NH3(g) + H2O(g)

Ammonia liquor, NH4OH is an highly unstable hydroxide of ammonium, hence it decomposes on heating to produce ammonia gas, NH3 which is liberated to the surroundings and water, H2O evaporated as steam. In a reverse reaction, ammoniacal liquor is formed by dissolving gaseous ammonia in cold water.

Thus, the products of NH4OH break down are NH3 and H2O

Serggg [28]

Answer:

2KClO3 -------> 2KCl + 3O2

Explanation:

First, in balancing a chemical reaction such as the one given in the question, you should understand that for an equation to be balanced, the number of atoms and ions on both sides of the equation that is the right and left side must be equal. This follows the law of conservation of mass which tells us that matter can neither be created nor destroyed but can be changed into another form.

Next is to begin balancing the equation by identifying and writing down the substances given:

KCl03 ---------> KCl + O2

Next is to count he number of the individual atoms on each side and find out if they are the same on both sides and if not you must follow the next step.

Add a corresponding number and use it to multiply the atoms involved

KClO3 ---------> KCl + O2

Oxygen is 3 on the left side and two on the other side, so we multiply the left hand side by 2 and the right hand side by 3

2KClO3 -----> KCl + 3O2

The potassium and Chlorine are no longer balanced, so you multiply the right had=nd side of KCl by 2.

2KClO3 -----> 2KCl + 3O2

The reactionis herefore balanced as both sides have equal number of atoms and ions.

As the two parental (template) DNA strands separate at a replication fork, each of the strands is separately copied by a DNA pol

Lapatulllka [165]

Answer:

Synthesis of leading strand:

daughter strand elongate towards replication fork

only one primer is needed

made continuously

Synthesis of the lagging strand:

multiple primers needed

daughter strand elongates away from replication fork

made in segments

Synthesis of both:

synthesized in 5' to 3'

Explanation:

The replication of DNA involves the unwinding of the double helix structure by the helicase enzyme after which RNA primer binds to form a bubble known as the replication fork.

DNA can only be replicated in the 5' to 3' direction because the polymerase that is responsible for the elongation of new strands can only add nucleotides in the 5' to 3' direction.

Hence, the leading strand is replicated continuously in this direction while the lagging strand is replicated discontinuously or fragments known as the okazaki fragments. The discontinuous replication of the lagging strand therefore requires different primers biding at multiple sites on the DNA strand.

Because of the nature of replication of the lagging strand, the elongation of the fragments moves away from the replication fork while that of the leading strand moves towards the replication fork.
