Explanation:
A freezing point is defined as the point in which a liquid state of a substance changes into solid state.
Whereas boiling point is defined as the point at which liquid state of substance starts to convert into vapor state.
So, a substance is freezing at 
and boils at 
then it means at room temperature, that is, around 
the substance is present in liquid state.
This is because between the freezing and boiling point a substance will always exist in liquid state.
Thus, we can conclude that state of the material at room temperature is liquid.
Answer:
The atmosphere is the superhighway in the sky that moves water everywhere over the Earth. Water at the Earth's surface evaporates into water vapor which rises up into the sky to become part of a cloud which will float off with the winds, eventually releasing water back to Earth as precipitation.

If you don't want to plagiarize change it up a bit.
Answer:
pH= 8.45
Explanation:
when working with strong accids pH = -log(Concentration)
so -log(3.58e-9) = 8.446
A bimolecular reaction typically takes twice as long as a unimolecular reaction. The answer is true
<h3>
How is activation energy related to temperature?</h3>
- Consider what must occur for ClNO2 to react with NO to understand why reactions have an activation energy.
- First and foremost, these two molecules must clash in order to organise the system.
- Not only must they be brought together, but they must also be kept in precisely the appropriate orientation relative to one other in order for the reaction to occur.
- Some energy must also be used in order to break the Cl-NO2 bond and allow the Cl-NO bond to form.

Explanation:
To balance a chemical equation, there are so many approaches to solve the problem.
A balanced chemical equation is one that obeys the law of conservation of matter.
According to this law "matter is neither created nor destroyed by atoms are just rearranged in chemical reaction".
This implies implies that equal number of atoms must be on both sides of the equation.
There are two main approaches to balancing chemical equation;
- Inspection
- mathematical equation
We can inspect the equation and affix the proper coefficients to combining species.
Mathematically, we establish simple solvable algebraic equations to find the number of respective coefficients that will balance the equation:
For example:
H₂ + O₂ → H₂O
mathematically;
aH₂ + bO₂ → cH₂O
conserving:
H : 2a = 2c
O: 2b = c
let a = 1
c = 1
b = 
multiply by 2 to give;
a = 2, b = 1 , c= 2
2H₂ + O₂ → 2H₂O
