Explanation:
As density is defined as the mass of a substance divided by its volume.
Mathematically, Density =
It is given that mass is 50 g and density is 0.934 .
Hence, calculate the volume of methyl acetate as follows.
Density =
0.934 =
Volume =
or, = (as 1
= 1 mL)
Thus, we can conclude that the volume of methyl acetate the student should pour out is .
Answer:
The initial rate of the reaction between substances P and Q was measured in a series of
experiments and the following rate equation was deduced.
Complete the table of data below for the reaction between P and Q
Explanation:
Given rate of the reaction is:
Substitute the given values in this formulae to get the [P], [Q] and rate values.
From the first row,
the value of k can be calulated:
Second row:
2. Rate value:
3.Third row:
4. Fourth row:
Answer:
The given statement is true.
Enzymes which are present in the digestive tract such as salivary amylase, pepsin, trypsin, et cetera mainly catalyze the hydrolysis reaction.
The hydrolysis reaction is the reaction by which large molecules are broken down into smaller molecules with the help of water.
Most of the complex molecules or nutrients such as starch, protein et cetera are broken down into their respective smaller units with the help of hydrolysis reaction.
For example, lactase catalyzes the hydrolysis of lactose into glucose and galactose.
