The correct answer to this question would be heat energy
Answer:
acquired traits are traits that organisms develops over a lifetime. adaptation are trait that enhances an organism's ability to survive and reproduce in its environment.
Answer:
A balanced chemical equation follows law of conservation of mass. This law states that mass can neither be created nor be destroyed but it can only be transformed from one form to another form. This means that total mass on the reactant side is equal to the total mass on the product side.
Answer:
Sand has a strong non-polar covalent connection, that prevents water to break it down.
Explanation:
Sand being composed of quartz and small particulars of minerals can only be dissolved in hot acids, unlikd sugar which can easily be broken down by water, due to the large magnetic molecular propery of water and the ability to evolve sugar in an Intermolecular manner.
Answer:
Coefficient in front of the
in the balanced equation - 4
Explanation:
The unbalanced reaction is shown below as:-
On the left hand side,
There are 1 nitrogen atom and 3 hydrogen atoms and 3 oxygen atoms
On the right hand side,
There are 1 nitrogen atom and 2 hydrogen atoms and 2 oxygen atoms
Thus,
Right side,
must be multiplied by 6 and
by 4
Left side,
is multiplied by 5 and
by 4 so to balance the whole reaction.
Thus, the balanced reaction is:-
<u>Coefficient in front of the
in the balanced equation - 4</u>
