The scientific method is defined as a method of research in which a problem is identified, relevant data is gathered, a hypothesis is formulated from this data, and the hypothesis is empirically tested.
Answer:
Hydrometers
Density can be measured using a variety of instruments. A hydrometer is used to determine the density
Explanation:
Answer:
Explanation:
photosynthesis
the given chemical reaction is photosynthesis.
During photosynthesis carbon dioxide absorbed by plants reacts with water in presence of sunlight to give glucose and oxygen.
Answer : The rate of the reaction if the concentration of
is doubled is, 0.006 M/s
Explanation :
Rate law : It is defined as the expression which expresses the rate of the reaction in terms of molar concentration of the reactants with each term raised to the power their stoichiometric coefficient of that reactant in the balanced chemical equation.
The balanced equations will be:

In this reaction,
and
are the reactants.
The rate law expression for the reaction is:
![\text{Rate}=k[CH_3Br][NaOH]](https://tex.z-dn.net/?f=%5Ctext%7BRate%7D%3Dk%5BCH_3Br%5D%5BNaOH%5D)
As we are given that:
= concentration of
= 0.100 M
= concentration of
= 0.100 M
Rate = 0.0030 M/s
Now put all the given values in the above expression, we get:


Now we have to calculate the rate of the reaction if the concentration of
is doubled.
![\text{Rate}=k[CH_3Br][NaOH]](https://tex.z-dn.net/?f=%5Ctext%7BRate%7D%3Dk%5BCH_3Br%5D%5BNaOH%5D)


Thus, the rate of the reaction if the concentration of
is doubled is, 0.006 M/s
It is fresher because of new transportation techniques and refrigerated trailers.
