A cation is a term that indicates a positively charged ion, that essentially results when an electrically neutral atom, loses its electrons, specifically electrons from its outer shell to another atom, primarily for the purpose of ionic bonding. When this occurs, the atom that donated its electrons, now has an indifference of protons and neutrons and this results in a positively charged species.

What is the biological significance of the temperature at which the amylase catalyzed reaction

ipn [44]

Answer:

The biological significance is that it is the normal human body temperature and also the optimum temperature of the enzyme.

Explanation:

Enzymes are biological catalysts that speed up the rate of chemical reactions.
Enzymes catalyze specific reactions by working on a specific substrate to convert it into a product.
The rate of enzyme activity depends on several factors which include pH, temperature, substrate concentration, and enzyme concentration among others.
Enzymes work best at a specific pH and temperature known as optimum pH and optimum temperature respectively.
In this case, enzyme amylase works best at a temperature of 37° C which is equivalent to the normal human body temperature.

Ocean water contains 3.5% NaCl by mass. How many grams of sodium chloride can be obtained from 750 g of seawater

Masteriza [31]

26.25g

Explanation:

Given parameters:

Percentage of NaCl in ocean water = 3.5%

Mass of given seawater = 750g

Unknown:

Mass of NaCl in the seawater = ?

Solution:

This is a simple percentage problem:

We have been given that ocean water contains 3.5% of NaCl;

Therefore;

Mass of NaCl in seawater = Percentage of NaCl in ocean water x Mass of seawater

Mass of NaCl in seawater = $\frac{3.5}{100}$ x 750g = 26.25g
